Some of these monographs may be thought of as an anthology of maps, which, like all anthologies, reflects the taste and predilection of the collector. Cartography, like architecture, has attributes of both a scientific and an artistic pursuit, a dichotomy that is certainly not satisfactorily reconciled in all presentations. The significance of maps - and much of their meaning in the past - derives from the fact that people make them to tell other people about the places or space they have experienced. It is assumed that cartography, like art, pre-dates writing; like pictures, map symbols are apt to be more universally understood than verbal or written ones. As previously mentioned, many early maps, especially those prior to the advent of mass production printing techniques, are known only through descriptions or references in the literature (having either perished or disappeared). Many libraries and collections were not in the habit of preserving maps that they considered a€?obsoletea€? and simply discarded them. A series of maps of one region, arranged in chronological order, can show vividly how it was discovered, explored by travelers and described in detail; this may be seen in facsimile atlases like those of America (K.
As mediators between an inner mental world and an outer physical world, maps are fundamental tools helping the human mind make sense of its universe at various scales. The history of cartography represents more than a technical and practical history of the artifacts. The only evidence we have for the mapmaking inclinations and talents of the inhabitants of Europe and adjacent parts of the Middle East and North Africa during the prehistoric period is the markings and designs on relatively indestructible materials.
Although some questions will always remain unanswered, there can be no doubt that prehistoric rock and mobiliary art as a whole constitutes a major testimony of early mana€™s expression of himself and his world view.
Despite the richness of civilization in ancient Babylonia and the recovery of whole archives and libraries, a mere handful of Babylonian maps have so far been found.
Egypt, which exercised so strong an influence on the ancient civilizations of southeast Europe and the Near East, has left us no more numerous cartographic documents than her neighbor Babylonia. In so far as cartography was concerned, perhaps the greatest extant Egyptian achievement is represented by the Turin Papyrus, collected by Bernardino Drovetti before 1824 (see monograph #102) .
In so far as cartography was concerned, perhaps the greatest extent that Egyptian achievement is represented is by the Turin Papyrus, collected by Bernardino Drovetti before 1824 (#102). It has often been remarked that the Greek contribution to cartography lay in the speculative and theoretical realms rather than in the practical realm, and nowhere is this truer than in the Archaic and Classical Period. To the Arab countries belongs chief credit for keeping alive an interest in astronomical studies during the so-called Christian middle ages, and we find them interested in globe construction, that is, in celestial globe construction; so far as we have knowledge, it seems doubtful that they undertook the construction of terrestrial globes.
Among the Christian peoples of Europe in this same period there was not wanting an interest in both geography and astronomy. Above the convex surface of the earth (ki-a) spread the sky (ana), itself divided into two regions - the highest heaven or firmament, which, with the fixed stars immovably attached to it, revolved, as round an axis or pivot, around an immensely high mountain, which joined it to the earth as a pillar, and was situated somewhere in the far North-East, some say North, and the lower heaven, where the planets - a sort of resplendent animals, seven in number, of beneficent nature - wandered forever on their appointed path. Now, it is remarkable that the Greeks, adopting the earlier Chaldean ideas concerning the sphericity of the earth, believed also in the circumfluent ocean; but they appear to have removed its position from latitudes encircling the Arctic regions to a latitude in close proximity to the equator. Notwithstanding this encroachment of the external ocean - encroachment which may have obliterated indications of a certain northern portion of Australia, and which certainly filled those regions with the great earth - surrounding river Okeanos - the traditions relating to the existence of an island, of immense extent, beyond the known world, were kept up, for they pervade the writings of many of the authors of antiquity. In a fragment of the works of Theopompus, preserved by Aelian, is the account of a conversation between Silenus and Midas, King of Phrygia, in which the former says that Europe, Asia, and Africa were lands surrounded by the sea; but that beyond this known world was another island, of immense extent, of which he gives a description. Theopompus declareth that Midas, the Phrygian, and Selenus were knit in familiaritie and acquaintance. The side of the boat curves inwards, so that when reversed the figure of it would be like an orange with a slice taken off the top, and then set on its flat side.
Comparing these early notions, as to the shape and extent of the habitable world, with the later ideas which limited the habitable portion of the globe to the equatorial regions, we may surmise how it came to pass that islands--to say nothing of continents which could not be represented for want of space - belonging to the southern hemisphere were set down as belonging to the northern hemisphere. We have no positive proof of this having been done at a very early period, as the earlier globes and maps have all disappeared; but we may safely conjecture as much, judging from copies that have been handed down. Early maps of the world, as distinguished from globes, take us back to a somewhat more remote period; they all bear most of the disproportions of the Ptolemaic geography, for none belonging to the pre-Ptolemaic period are known to exist. We have seen that, according to the earliest geographical notions, the habitable world was represented as having the shape of an inverted round boat, with a broad river or ocean flowing all round its rim, beyond which opened out the Abyss or bottomless pit, which was beneath the habitable crust.
The description is sufficiently clear, and there is no mistaking its general sense, the only point that needs elucidation being that which refers to the position of the earth or globe as viewed by the spectator. Our modern notions and our way of looking at a terrestrial globe or map with the north at the top, would lead us to conclude that the abyss or bottomless pit of the inverted Chaldean boat, the Hades and Tartaros of the Greek conception, should be situated to the south, somewhere in the Antarctic regions.
The internal evidence of the Poems points to a northern as well as a southern location for the entrance to the infernal regions.
Another probable source of information: The Phoinikes of Homer are the same Phoenicians who as pilots of King Solomona€™s fleets brought gold and silver, ivory, apes and peacocks from Asia beyond the Ganges and the East Indian islands. European mariners and geographers of the Homeric period considered the bearing of land and sea only in connection with the rising and setting of the sun and with the four winds Boreas, Euros, Notos, and Sephuros. These mariners and geographers adopted the plan - an arbitrary one - of considering the earth as having the north above and the south below, and, after globes or maps had been constructed with the north at the top, and this method had been handed down to us, we took for granted that it had obtained universally and in all times.
Such has not been the case, for the earliest navigators, the Phoenicians, the Arabs, the Chinese, and perhaps all Asiatic nations, considered the south to be above and the north below.
It is strange that some historians, in pointing out so cleverly that the Chaldean conception was more in accordance with the true doctrine concerning the form of the globe than had been suspected, fails, at the same time, to notice that Homer in his brain-map reversed the Chaldean terrestrial globe and placed the north at the top.
During the middle ages, we shall see a reversion take place, and the terrestrial paradise and heavenly paradise placed according to the earlier Chaldean notions; and on maps of this epoch, encircling the known world from the North Pole to the equator, flows the antic Ocean, which in days of yore encircled the infernal regions. At a later period, during which planispheric maps, showing one hemisphere of the world, may have been constructed, the circumfluent ocean must have encircled the world as represented by the geographical exponents of the time being; albeit in a totally different way than expressed in the Shumiro-Accadian records. It follows from all this that, as mariners did actually traverse those regions and penetrate south of the equator, the islands they visited most, such as Java, its eastern prolongation of islands, Sumbawa, etc., were believed to be in the northern hemisphere, and were consequently placed there by geographers, as the earliest maps of the various editions of Ptolemya€™s Geography bear witness.
These mistakes were the result doubtless of an erroneous interpretation of information received; and the most likely period during which cognizance of these islands was obtained was when Alexandria was the center of the Eastern and Western commerce of the world. But to return to the earlier Pre-Ptolemaic period and to form an idea of the chances of information which the traffic carried on in the Indian Ocean may have offered to the Greeks and Romans, here is what Antonio Galvano, Governor of Ternate says in 1555, quoting Strabo and Pliny (Strabo, lib. Now as the above articles of commerce, mentioned by Strabo and Pliny, after leaving their original ports in Asia and Austral-Asia, were conveyed from one island to another, any information, when sought for, concerning the location of the islands from which the spices came, must necessarily have been of a very unreliable character, for the different islands at which any stay was made were invariably confounded with those from which the spices originally came. From these facts, and many others, such as the positions given to the Mountain of the East or North-East of the Shumiro-Accads, the Mountain of the South, or Southwest, of Homer, and the Infernal Regions, we may conclude that the North Pole of the Ancients was situated somewhere in the neighborhood of the Sea of Okhotsk. It is in the Classical Period of Greek cartography that we can start to trace a continuous tradition of theoretical concepts about the size and shape of the earth. Likewise, it should be emphasized that the vast majority of our knowledge about Greek cartography in this early period is known primarily only from second- or third-hand accounts. There is no complete break between the development of cartography in Classical and in Hellenistic Greece. In spite of these speculations, however, Greek cartography might have remained largely the province of philosophy had it not been for a vigorous and parallel growth of empirical knowledge. That such a change should occur is due both to political and military factors and to cultural developments within Greek society as a whole.
The librarians not only brought together existing texts, they corrected them for publication, listed them in descriptive catalogs, and tried to keep them up to date. The other great factor underlying the increasing realism of maps of the inhabited world in the Hellenistic Period was the expansion of the Greek world through conquest and discovery, with a consequent acquisition of new geographical knowledge. Among the contemporaries of Alexander was Pytheas, a navigator and astronomer from Massalia [Marseilles], who as a private citizen embarked upon an exploration of the oceanic coasts of Western Europe. As exemplified by the journeys of Alexander and Pytheas, the combination of theoretical knowledge with direct observation and the fruits of extensive travel gradually provided new data for the compilation of world maps.
The importance of the Hellenistic Period in the history of ancient world cartography, however, has been clearly established. In the history of geographical (or terrestrial) mapping, the great practical step forward during this period was to locate the inhabited world exactly on the terrestrial globe. Thus it was at various scales of mapping, from the purely local to the representation of the cosmos, that the Greeks of the Hellenistic Period enhanced and then disseminated a knowledge of maps.
The Roman Republic offers a good case for continuing to treat the Greek contribution to mapping as a separate strand in the history of classical cartography. The remarkable influence of Ptolemy on the development of European, Arabic, and ultimately world cartography can hardly be denied. Notwithstanding his immense importance in the study of the history of cartography, Ptolemy remains in many respects a complicated figure to assess. Still the culmination of Greek cartographic thought is seen in the work of Claudius Ptolemy, who worked within the framework of the early Roman Empire. When we turn to Roman cartography, it has been shown that by the end of the Augustan era many of its essential characteristics were already in existence.
In the course of the early empire large-scale maps were harnessed to a number of clearly defined aspects of everyday life. Maps in the period of the decline of the empire and its sequel in the Byzantine civilization were of course greatly influenced by Christianity. Continuity between the classical period and succeeding ages was interrupted, and there was disruption of the old way of life with its technological achievements, which also involved mapmaking. The Byzantine Empire, though providing essential links in the chain, remains something of an enigma for the history of the long-term transmission of cartographic knowledge from the ancient to the modern world. It may be necessary to emphasize that the ancient Greek maps shown in this volume are a€?reconstructionsa€? by modern scholars based upon the textual descriptions of the general outline of the geographical systems formed by each of the successive Greek writers so far as it is possible to extract these from their writings alone. China is Asiaa€™s oldest civilization, and the center from which cultural disciplines spread to the rest of the continent. An ancient wooden map discovered by Chinese archaeologists in northwest China's Gansu Province has been confirmed as the country's oldest one at an age of more than 2,200. The map of Guixian was unearthed from tombs of the Qin Kingdom at Fangmatan in Tianshui City of Gansu Province in 1986 and was listed as a national treasure in 1994. Unlike modern maps, place names on these maps were written within big or small square frames, while the names of rivers, roads, major mountains, water systems and forested areas were marked directly with Chinese characters. Whoever sets out to write on the history of geography in China faces a quandary, however, for while it is indispensable to give the reader some appreciation of the immense mass of literature which Chinese scholars have produced on the subject, it is necessary to avoid the tedium of listing names of authors and books, some of which indeed have long been lost. As for the ideas about the shape of the earth current in ancient Chinese thought, the prevailing belief was that the heavens were round and the earth square. The following attempts to compare rather carefully the parallel march of scientific geography in the West and in China. DESCRIPTION: During the Middle Ages the Greek tradition of disinterested research was stifled in Western Europe by a theological dictatorship which bade fair, for a time, to destroy all hope of a genuine intellectual revival.
Most Arab cartographers also used Ptolemya€™s instructions in the construction of their own maps. Over the years, these enlightened Arabs injected new life and a storehouse of knowledge into the relatively backward science of Western Europe, and, for centuries, Arab culture actually dominated the Iberian Peninsula and Sicily. In the year 1138, the royal palace at Palermo, Sicily was the scene of a long-awaited meeting between an unusual Christian king and a distinguished Muslim scholar. The monarch was Roger II, King of Sicily; his distinguished guest the Arab geographer Abu Abdullah Mohammed Ibn al-Sharif al-Idrisi [Edrisi].
Al-Idrisia€™s writings tell us less about his own character and personality than about those of the man who became his host and patron. Sicily in particular was an ideal meeting ground for the two civilizations a€“ Christian Europe and the Muslim Middle East.
Early in the 11th century a band of Norman adventurers, the Hautevilles, had ridden into southern Italy to wrest it from the Byzantine Greeks and the Muslims, and in 1101 Count Roger da€™Hauteville capped his career by conquering Sicily.
Tall, dark-haired, bearded and corpulent, Roger, from a magnificent palace in Palermo, ruled his kingdom with a balanced mixture of diplomacy, ruthlessness, wisdom and skill that has led many historians to term his kingdom the best-governed European state of the Middle Ages.
Rogera€™s interest in geography was the expression of a scientific curiosity just awakening in Europe, but inevitably he turned to a Muslim for help. A few practical maps did exista€”marinersa€™ charts showing coastlines, capes, bays, shallows, ports of call and watering and provisioning placesa€”but in a typical medieval divorce of science and technology, these remained in the hands of navigators. To carry out the project, Roger established an academy of geographers, with himself as director and al-Idrisi as permanent secretary, to gather and analyze information. The academy began by studying and comparing the works of previous geographersa€”principal among them 12 scholars, 10 of them from the Muslim world.
Al-Idrisia€™s two geographers from the pre-Islamic era were Paulus Orosius, a Spaniard whose popular History, written in the fifth century, included a volume of descriptive geography; and Ptolemy, the greatest of the classical geographers, whose Geography, written in the second century, had been entirely lost to Europe, but preserved in the Muslim world in an Arabic translation. After examining at length the geographical works they had collected, the king and the geographer observed that they were full of discrepancies and omissions, and decided to embark on original research.
During this research, al-Idrisi and Roger compared data, keeping the facts on which travelers agreed and eliminating conflicting information.
Finally, however, the long 15-year geographical study was finished and the task of map making began. Al-Idrisi explained that the disk merely symbolized the shape of the world: The earth is round like a sphere, and the waters adhere to it and are maintained on it through natural equilibrium which suffers no variation. By al-Idrisia€™s time, Muslim astronomers had made great strides in methods of reckoning latitude. Al-Idrisi himself gave three figures for the eartha€™s circumference, without deciding among them: Eratosthenesa€™ approximately correct estimate, a slightly smaller figure arrived at by Indian astronomers, and a still smaller numbera€”though larger than Ptolemya€™sa€”which was apparently agreed on by Sicilian scholars.
On the disk, according to al-Idrisia€™s own account, were incised a€?by skillful workersa€? lines marking the limits of the seven climates of the habitable world, arbitrary divisions established by Ptolemy running east and west and bounded by parallels of latitude, from the Arctic to the Equator. The map, written in Arabic, shows the Eurasian continent in its entirety, but only shows the northern part of the African continent. The resulting book and associated maps which took 15 years to amass are, for this and the above reasons, unquestionably among the most interesting monuments of Arabian geography. Modern geographers have attempted to reconstruct the features of the silver planisphere by using a combination of the maps of Rogera€™s Book, which has survived in several texts, and its tables of longitudes and latitudes. Distortions, omissions, and misconceptions notwithstanding, the superiority of al-Idrisia€™s map over the world maps of medieval Europe is striking. The first division of the first climate commences to the west of the Western Sea, which Idrisi called the Sea of Darkness. Following the Nile, still eastward, we find the nomadic Berbers who pasture their flock on the borders of a river flowing from the east, debouching into the Nile stream.
It is clear that the part of southern Africa which is extended far to the east is a legacy from Ptolemy, but Arabian seafarers had taught Idrisi that the sea was open in the east, and in his own commentaries he writes: a€?The Sea of Sin [China] is an arm of the ocean which is called the Dark Sea [the Atlantic]a€?. To the south al-Idrisi pictured a great river, the Nile of the Negroes, a composite of the Senegal and the Niger Rivers that flowed from Central Africa west to the Atlantic.
Sicily, naturally, came in for special praise; it was a pearl of the age, and al-Idrisi told the story of the Norman conquest of the island by Roger da€™Hauteville, the greatest of Frankish princes, followed by the succession of the great king who bears the same name and who follows in his footsteps.
Idrisi was not, however, able to put the countries around the Baltic into proper shape, even though his notes show him to have been familiar with a great many places there, as in the rest of Europe.
The impressive assemblage of facts from travelersa€™ accounts and geographical writings was interrupted now and then by fables, some taken directly from Ptolemy, some from popular folklore. Al-Idrisia€™s Rome had an oriental magnificence; ships with their freight sailed up the Tiber to be drawn thus loaded right up to the very shops of the merchants. The Arabs knew these islands through Ptolemy, and called them Jazaa€™ir al-Khalidat [The Eternal Isles], presumably a version of the Greek name. After telling us that the Canaries had been visited by Alexander the Great and that the tomb of a pre-Islamic South Arabian king, made of marble and colored glass, can be seen on one of them, al-Idrisi gives the names of two of the islands. Even more interesting is al-Idrisia€™s account of an actual voyage of exploration into the western Atlantic, undertaken by 80 brave men from Lisbon whom he calls the mugharrirun, best rendered as a€?intrepid explorers.a€? The expedition must have taken place before 1147 - the date Lisbon fell to the Christians - but it is impossible to be more precise. It was from the city of Lisbon that the mugharrirun set out to sail the Sea of Darkness in order to discover what was in it and where it ended, as we have mentioned before. The inhabitants of the island of al-Sua€™ali are shaped like women and their canine teeth protrude. The island of Qalhan is inhabited by animal-headed people who swim in the sea to catch their food. Al-Ghawr makes sense; it means a depression surrounded by higher land, and occurs elsewhere in the Arab world as a place name. Al-Idrisi gives the names of 13 islands in the western Atlantic; a 14th, visited by the mugharrirun, is nameless.
On his map, Idrisi shows a long string of islands in the Western Ocean reaching north from the equator to Brittany. However, Arab geographers and astronomers were much too accurate in their latitude calculations to mistakenly spread the Canary Islands so widely over the ocean. The three intermediate islands in the chain may be the first cartographic representation of the Azores. Idrisia€™s description of other islands in the Atlantic appear to have more to do with fanciful legends than with reality.
Some of these islands resemble the islands of Irish legend, and the Arabs may have incorporated parts of the Celtic tradition into their own legends. At the latitude of Tangier, in the Grand Sea, there are situated islands named a€?The Fortunate Islands.a€? These are spread in the sea, not far away from the west coast [of Africa], the Barbary Coast.
Al-Idrisi presented the planisphere, a silver celestial sphere and the book to his patron in 1154, just a few weeks before Roger died at 58, probably of a heart attack; he went on to compose another geographical work for William I, Rogera€™s successor. According to Arab sources, Idrisi composed yet another more detailed text and map in 1161 for Rogera€™s son William II. In 1160, however, Sicilian barons rose in rebellion against William and during the disorders looted the palace; in a great fire in the courtyard, they burned government records, books and documentsa€”including a new Latin edition of Rogera€™s Book which al-Idrisi had presented to William. Since the barons had attacked the Muslims of Sicily with particular ferocitya€”killing, among many others, a famous poet named Yahya ibn al-Tifashia€”al-Idrisi fled to North Africa where, six years later, he died.
As he had brought the Arabic text with him, however, his great work lived on, winning widespread fame, serving as a model for Muslim geographers and historians for centuries and providing the great Muslim historian, Ibn Khaldun, with practically all his geographical knowledge.
It is a curious thought that had Columbus been aware of the true distancea€”from al-Idrisia€™s estimatesa€”he might have hesitated to undertake his epoch-making voyage and might never have discovered that new world which came to light one morning on the far side of the Sea of Darkness.
Idrisia€™s works are of exceptional quality when considered in comparison with other geographical writings of their period, partly by reason of their richness of detail, but mainly because of the afore mentioned a€?scientific methoda€™ that was employed, a procedure which was indeed unlike that adopted by most Latin scholars of that era. There is, however, a markedly retrograde character to certain portions of his work, such as East Africa and South Asia; despite his narrative of the Lisbon Wanderers (see above and Beazely, vol.
In view of its modernity and high intrinsic worth, it is difficult to understand why Idrisia€™s work, composed as it was at the chronological and geographical point of contact between the Islamic and Christian civilizations, remained so long un-utilized by Christian scholars in Sicily, Italy, or other Christian countries, until we remember that the primary - we might even say the sole - interest of the Latin West in Arabic literature centered on the preparation of calendars, star tables and horoscopes, and, to some extent, the recovery of ancient lore. Al-Idrisia€™s map places Gog and Magog in northern China, behind a great wall with a tower and a door; at the wall is an inscription, translated as a€?belongs to the Kufaya mountain range which encloses Gog and Magoga€?.
The first translation known of Idrisia€™s work was published in Rome only in 1619, and then in a very much shortened form (the translator did not even know the authora€™s name). On the other hand, there is no question but that the Sicilo-Norman enthusiasm for geography exerted an indirect influence on the evolution of geographical knowledge, an influence that was to make itself felt more especially after the close of the Crusades period.

A knowledge of maps and their contents is not automatic - it has to be learned; and it is important for educated people to know about maps even though they may not be called upon to make them. Some maps are successful in their display of material but are scientifically barren, while in others an important message may be obscured because of the poverty of presentation. Maps constitute a specialized graphic language, an instrument of communication that has influenced behavioral characteristics and the social life of humanity throughout history.
Maps produced by contemporary primitive peoples have been likened to so-called prehistoric maps. In earlier times these maps were considered to be ephemeral material, like newspapers and pamphlets, and large wall-maps received particularly careless treatment because they were difficult to store. When, in 1918, a mosaic floor was discovered in the ancient TransJordanian church of Madaba showing a map of Palestine, Syria and part of Egypt, a whole series of reproductions and treatises was published on the geography of Palestine at that time. Kretschner, 1892), Japan (P.Teleki, 1909), Madagascar (Gravier, 1896), Albania (Nopcsa, 1916), Spitzbergen (Wieder, 1919), the northwest of America (Wagner, 1937), and others. Indeed, much of its universal appeal is that the simpler types of map can be read and interpreted with only a little training. Crone remarked that a€?a map can be considered from several aspects, as a scientific report, a historical document, a research tool, and an object of art. It may also be viewed as an aspect of the history of human thought, so that while the study of the techniques that influence the medium of that thought is important, it also considers the social significance of cartographic innovation and the way maps have impinged on the many other facets of human history they touch. It is reasonable to expect some evidence in this art of the societya€™s spatial consciousness. There is, for example, clear evidence in the prehistoric art of Europe that maps - permanent graphic images epitomizing the spatial distribution of objects and events - were being made as early as the Upper Paleolithic. In Mesopotamia the invention by the Sumerians of cuneiform writing in the fourth millennium B.C. In the former field, among other things, they attained a remarkably close approximation for a?s2, namely 1.414213.
The courses of the Tigris and Euphrates rivers offered major routes to and from the north, and the northwest, and the Persian Gulf allowed contact by sea along the coasts of Arabia and east to India. Within this span of some three thousand years, the main achievements in Greek cartography took place from about the sixth century B.C.
Stevenson, it is not easy to fix, with anything like a satisfactory measure of certainty, the beginning of globe construction; very naturally it was not until a spherical theory concerning the heavens and the earth had been accepted, and for this we are led back quite to Aristotle and beyond, back indeed to the Pythagoreans if not yet farther. We are now learning that those centuries were not entirely barren of a certain interest in sciences other than theological.
It has now been ascertained and demonstrated beyond doubt that the earliest ideas concerning the laws of the universe and the shape of the earth were, in many respects, more correct and clearer than those of a subsequent period. Ragozin, says the Shumiro-Accads had formed a very elaborate and clever idea of what they supposed the world to be like; they imagined it to have the shape of an inverted round boat or bowl, the thickness of which would represent the mixture of land and water (ki-a) which we call the crust of the earth, while the hollow beneath this inhabitable crust was fancied as a bottomless pit or abyss (ge), in which dwelt many powers. The account of this conversation, which is too lengthy here to give in full, was written three centuries and a half before the Christian era. Of the familiaritie of Midas, the Phrigian, and Selenus, and of certaine circumstances which he incredibly reported. This Selenus was the sonne of a nymphe inferiour to the gods in condition and degree, but superiour to men concerning mortalytie and death. The Chaldean conception, thus rudely described, shows a yet nearer approximation to the true doctrine concerning the form of the globe, when we bear in mind that this actually is in shape a flattened sphere, with the vertical diameter the shorter one.
A curious example of the difficulties that early cartographers of the circumfluent ocean period had to contend with, and of the sans faA§on method of dealing with them, occurs in the celebrated Fra Mauro mappamundi (Book III, #249), which is one of the last in which the external ocean is still retained. The influence of the Ptolemaic astronomical and geographical system was very great, and lasted for over thirteen hundred years. There are reasons to believe however, apart from the evidence we gather in the Poems, that these abyssal regions were supposed or believed to be situated around the North Pole. Homer, The Outward Geography Eastwards: a€?The outer geography eastwards, or wonderland, has for its exterior boundary the great river Okeanos, a noble conception, in everlasting flux and reflux, roundabout the territory given to living man. The Phoenician reports referred to came most likely therefore, not so much from the north, as from these regions which, tradition tells us (Fra Mauroa€™s mappamundi #249), were situated propinqua ale tenebre.
These winds covered the arcs intervening between our four cardinal points of the compass, which points were not located exactly as with us; but the north leaning to the east, the east to the south, the south to the west and the west to the north (see Beatusa€™ Turin map, Book II, #207). The reason for this is plausible, for whereas the northern seaman regulated his navigation by the North Star, the Asiatic sailor turned to southern constellations for his guidance. This is all the more strange when we take into consideration that, in the light of his context, the fact is apparent and of great importance as coinciding with other European views concerning the location of the north on terrestrial globes and maps. The Chaldeans placed their heaven in the east or northeast; Homer placed his heaven in the south or southwest. In this ocean we find also EA the Exalted Fish, but, deprived of his ancient grandeur and divinity, he is no doubt considered nothing more than a merman at the period when acquaintance is renewed with him on the SchA¶ner-Frankfort gores of Asiatic origin bearing the date 1515 (Book IV, #328). The divergence was probably owing in a great measure to the inability of representing graphically the perspective appearance of the globe on a plane; but may be also traceable to an erroneous interpretation of the original idea, caused by the reversion of the cardinal points of the compass. According to this division other continents south of the equator were supposed to exist and habited, some said, but not to be approached by those inhabiting the northern hemisphere on account of the presumed impossibility of traversing the equatorial regions, the heat of which was believed to be too intense.
We shall see, when dealing with Ptolemy's map of the world, some of the results of this confusion. Thomas, after the dispersion of the Apostles, preached the Gospel to the Parthians and Persians; then went to India, where he gave up his life for Jesus Christ.
That he corroborates Homera€™s views as to the sphericity of the earth by describing Cratesa€™ terrestrial globe (Geographica; Book ii.

That he accentuates Homera€™s views concerning the black races that lived some in the west (the African race) others in the east (the Australian race). That he shows the four cardinal points of the compass to have been situated somewhat differently than with us, for he says (Book 1, c. That he appears to be perpetuating an ancient tradition when he supposes the existence of a vast continent or antichthonos in the southern hemisphere to counterbalance the weight of the northern continents. The relativeness of these positions appears to have been maintained on some mediaeval maps. To appreciate how this period laid the foundations for the developments of the ensuing Hellenistic Period, it is necessary to draw on a wide range of Greek writings containing references to maps.
We have no original texts of Anaximander, Pythagoras, or Eratosthenes - all pillars of the development of Greek cartographic thought. In contrast to many periods in the ancient and medieval world and despite the fragmentary artifacts, we are able to reconstruct throughout the Greek period, and indeed into the Roman, a continuum in cartographic thought and practice.
Indeed, one of the salient trends in the history of the Hellenistic Period of cartography was the growing tendency to relate theories and mathematical models to newly acquired facts about the world - especially those gathered in the course of Greek exploration or embodied in direct observations such as those recorded by Eratosthenes in his scientific measurement of the circumference of the earth. With respect to the latter, we can see how Greek cartography started to be influenced by a new infrastructure for learning that had a profound effect on the growth of formalized knowledge in general. Thus Alexandria became a clearing-house for cartographic and geographical knowledge; it was a center where this could be codified and evaluated and where, we may assume, new maps as well as texts could be produced in parallel with the growth of empirical knowledge. In his treatise On the Ocean, Pytheas relates his journey and provides geographical and astronomical information about the countries that he observed. While we can assume a priori that such a linkage was crucial to the development of Hellenistic cartography, again there is no hard evidence, as in so many other aspects of its history, that allows us to reconstruct the technical processes and physical qualities of the maps themselves.
Its outstanding characteristic was the fruitful marriage of theoretical and empirical knowledge. Eratosthenes was apparently the first to accomplish this, and his map was the earliest scientific attempt to give the different parts of the world represented on a plane surface approximately their true proportions.
By so improving the mimesis or imitation of the world, founded on sound theoretical premises, they made other intellectual advances possible and helped to extend the Greek vision far beyond the Aegean.
While there was a considerable blending and interdependence of Greek and Roman concepts and skills, the fundamental distinction between the often theoretical nature of the Greek contribution and the increasingly practical uses for maps devised by the Romans forms a familiar but satisfactory division for their respective cartographic influences. The profound difference between the Roman and the Greek mind is illustrated with peculiar clarity in their maps. Through both the Mathematical Syntaxis (a treatise on mathematics and astronomy in thirteen books, also called the Almagest and the Geography (in eight books), it can be said that Ptolemy tended to dominate both astronomy and geography, and hence their cartographic manifestations, for over fourteen centuries. A modern analysis of Ptolemaic scholarship offers nothing to revise the long-held consensus that he is a key figure in the long term development of scientific mapping. In its most obvious aspect, the exaggerated size of Jerusalem on the Madaba mosaic map (# 121) was no doubt an attempt to make the Holy City not only dominant but also more accurately depicted in this difficult medium. In both Western Europe and Byzantium relatively little that was new in cartography developed during the Dark Ages and early Middle Ages, although monks were assiduously copying out and preserving the written work of many past centuries available to them. Researcher He said that the map, drawn in black on four pine wood plates of almost the same size, had clear and complete graphics depicting the administrative division, a general picture of local geography and the economic situation in Guixian County in the Warring States era. Only a few examples can be given, but it should be understood, even when it is not expressly said, that they must often stand simply as representative of a whole class of works.
It may be said at the outset that both in East and West there seem to have been two separate traditions, one which we may call a€?scientific, or quantitative, cartographya€™, and one which we may call a€?religious, or symbolic, cosmographya€™.
With this basis the Muslims combined the accumulated knowledge gained through exploration and travel.
As his visitor entered the hall, the king rose, took his hand and led him across the carpeted marble to a place of honor beside the throne. Born in Ceuta, Morocco, across the strait from Spain, al-Idrisi was then in his late 30a€™s. Roger II, son of a Norman-French soldier of fortune who had conquered Sicily at the beginning of the 12th century, was an anomaly among Christian monarchs of his time.
Captured by the Arabs in 831, the island had remained in Muslim control until the end of the 11th century.
Four years later, he passed the territory on to his son, Roger, who in 1130 was crowned king as Roger II. His energy was a legenda€”one commentator remarked that Roger accomplished more asleep than other sovereigns did awakea€”and his court boasted a collection of philosophers, mathematicians, doctors, geographers and poets who had no superior in Europea€”and in whose company he spent much of his time. Christian Europea€™s approach to map-making was still symbolic and fanciful, based on tradition and myth rather than scientific investigation, and used to illustrate books of pilgrimage, Biblical exegesis and other works.
He wanted to know the precise conditions of every area under his rule, and of the world outsidea€”its boundaries, climate, roads, the rivers that watered its lands, and the seas that bathed its coasts.
Sicilya€™s busy and cosmopolitan ports provided an ideal place for such an inquiry, and for years hardly a ship docked at Palermo, Messina, Catania or Syracuse without its crew and passengers being interrogated about the places they had visited. This process of collecting and assessing material took 15 years, during which, according to al-Idrisi, hardly a day passed when the king did not confer personally with the geographers, studying accounts that disagreed, examining astronomical coordinates, tables and itineraries, poring over books and weighing divergent opinions. First, under al-Idrisia€™s direction, a working copy was produced on a drawing board, with places sited on the map with compasses, following the tables that had already been prepared. Although Ptolemy had discussed several kinds of projection (Book I, #119), the problem of flattening out the surface of a sphere so that it could be represented on a flat map would not be solved until the 16th and 17th centuriesa€”the Age of Explorationa€”and none too satisfactorily even then. Zach states in 1806 that a€?the oldest terrestrial globe that is known was made for King Roger II of Sicily in the 12th century, and is especially remarkable for the value of the metal which was used in its construction, this being 400 pounds of silver.
Below the Equator, an unexplored southern temperate zone was thought to be separated from the familiar northern one by an impassable area of deadly heat.
Two are in the BibliothA?que Nationale de France, including the oldest, dated to about 1300 (MS Arabe 2221). From this reconstruction it is evident that, like Ptolemy, al-Idrisi pictured the habitable world as occupying 180 of the 360 degrees of the worlda€™s longitude, from the Atlantic in the West to China in the East, and 64 degrees of its latitude, from the Arctic Ocean to the Equator. Contrasted with the quaint and picturesque, but almost totally uninformative maps of the Christian scholars, the features of Europe, North Africa and the Middle East are easily recognizable in al-Idrisia€™s representationa€”Britain, Ireland, Spain, Italy, the Red Sea and the Nile. He had no doubt met travelers and merchants from Scandinavia at the court of King Roger and received important information from them, but we know that the Arabs too had connections with the Baltic peoples and also those in Russia at that time.
In Russia, winter daylight periods were so short that there was hardly time for Muslim travelers to perform all five obligatory daily prayers. Paris (Abariz) earned a condescending reference as a town of mediocre size, surrounded by vineyards and forests, situated on an island in the Seine, which surrounds it on all sides; however, it is extremely agreeable, strong, and susceptible of defense. The Strait of Gibraltar, according to Rogera€™s Book, did not exist when Alexander the Greata€”as medieval legend had ita€”invaded Spain.
Discovered by Hanno in the fifth century BC, they were explored and colonized in 25 BC by Juba II, erudite king of Mauretania and husband of Cleopatra Selene, daughter of Antony and Cleopatra. Some sources speak of these islands as if they were legendary, telling us for example that on each of the six islands - there are in fact seven - there was a bronze statue, like the one in CA?diz, warning voyagers to turn back. The mugharrirun were so famous for their exploit that a street in Lisbon was named after them. A street in Lisbon, near the hot springs, is still known as a€?The Street of the Intrepid Explorersa€?; it is named after them.
It is hard to escape the impression that we owe the preservation of this account largely to the folk etymology in the last line. The Azores are named after a kind of goshawk - in Portuguese, aA§or - prevalent there at the time of discovery.
The inhabitants threw stones at the travelers and hurt several of Alexandera€™s companions. A small fresh-water river runs down from the foot of the mountain, where the inhabitants live.
Al-Mustashkin is probably a corruption of al-mushtakin, meaning a€?the complainersa€? - appropriate enough for a population in thrall to a dragon. The Two Brothers could be the two small islands off Lanzarote in the Canaries, Alegranza and Graciosa, or indeed, any two prominent rocks off their coasts. This unnamed island, together with Masfahan, Laghus, The Two Brothers and possibly Sawa, are almost certainly islands in the Canary group. After describing the Canary Islands, Idrisi refers to an island in the Western Sea named Raqa, which is the Isle of the Birds, Djaziratoa€™t-Toyour. Distinct from the Canary Islands were the Isle of Female Devils, the Isle of Illusion, the Island of Two Sorcerers, and the Isle of Lamentation [Gazirat al-Mustashkin], which was inhabited and fertile, with tilled fields, but controlled by a terrible dragon. An exchange of ideas and reciprocal influences between the two cultures certainly took place. This work is said to have been even more extensive than his earlier one, but only a few extracts have survived.
At the same time, the silver planisphere and celestial sphere disappeared, apparently cut up and melted down. Although the Arabic text of Rogera€™s Book was published in Rome by the Medici press in 1592, it was not again available to Europeans in Latin until the 17th century.
Certainly the influence of Idrisia€™s Geography could not have been great in the world of letters or else traces of it would more easily be detected in Western literature. An explicit reference to Dul-Karnaia€™in (an Arabic name for Alexander, among others) by the gate, leaves no doubt as to Idrisia€™s source. Displays a Ptolemaic construction with an arrangement of horizontal divisions into seven parallel climate zones, originally oriented with South at the top. When it comes to creating custom windows and doors of distinction, steel is the obvious choice. They have often served as memory banks for spatial data and as mnemonics in societies without the printed word and can speak across the barriers of ordinary language, constituting a common language used by men of different races and tongues to express the relationship of their society to a geographic environment. Certain carvings on bone and petroglyphs have been identified as prehistoric route maps, although according to a strict definition, they might not qualify as a€?mapsa€?. In the present work, reconstruction of maps no longer extant are used in place of originals or assumed originals. Since the maps were missing, he drew them himself from indications in the ancient text, and when the work was finished, he commemorated this too in verse. The map answered many hitherto insoluble or disputed questions, for example the question as to where the Virgin Mary met the mother of John Baptist. A series of maps of a coastal region (for example, that of Holland or Friesland) or of river estuaries (the Po, Mississippi, Volga, or lower Yellow River) gives information on the rate of changes in outline and their causes.
Maps represent an excellent mirror of culture and civilizationa€?, but they are also more than a mere reflection: maps in their own right enter the historical process by means of reciprocally structured relationships. But when it comes to drawing up the balance sheet of evidence for prehistoric maps, we must admit that the evidence is tenuous and certainly inconclusive. The same evidence shows, too, that the quintessentially cartographic concept of representation in plan was already in use in that period. Our divisions into 60 and 360 for minutes, seconds and degrees are a direct inheritance from the Babylonians, who thought in these terms. The Pharaohs organized military campaigns, trade missions, and even purely geographical expeditions to explore various countries. From earliest times much of the area covered by the annual Nile floods had, upon their retreat, to be re-surveyed in order to establish the exact boundaries of properties. We find allusions to celestial globes in the days of Eudoxus and Archimedes, to terrestrial globes in the days of Crates and Hipparchus. In Justiniana€™s day, or near it, one Leontius Mechanicus busied himself in Constantinople with globe construction, and we have left to us his brief descriptive reference to his work.
But above all these, higher in rank and greater in power, is the Spirit (Zi) of heaven (ana), ZI-ANA, or, as often, simply ANA--Heaven. On this map of the world the islands of the Malay Archipelago follow the shores of Asia from Malacca to Japan. Even the Arabs, who, after the fall of the Roman Empire, developed the geographical knowledge of the world during the first period of the middle ages, adopted many of its errors. Volcanoes were supposed to be the entrances to the infernal regions, and towards the southeast the whole region beyond the river Okeanos of Homer, from Java to Sumbawa and the Sea of Banda, was sufficiently studded with mighty peaks to warrant the idea they may have originated. Many cartographers of the renascence, whose charts indeed we cannot read unless we reverse them, must have followed Asiatic cartographical methods, and this perhaps through copying local charts obtained in the countries visited by them. Taprobana was the Greek corruption of the Tamravarna of Arabian, or even perhaps Phoenician, nomenclature; our modern Sumatra.
Geographical science was on the eve of reaching its apogee with the Greeks, were it was doomed to retrograde with the decline of the Roman Empire. John III, King of Portugal, ordered his remains to be sought for in a little ruined chapel that was over his tomb, outside Meliapur or Maliapor. In some cases the authors of these texts are not normally thought of in the context of geographic or cartographic science, but nevertheless they reflect a widespread and often critical interest in such questions.
In particular, there are relatively few surviving artifacts in the form of graphic representations that may be considered maps. Despite a continuing lack of surviving maps and original texts throughout the period - which continues to limit our understanding of the changing form and content of cartography - it can be shown that, by the perioda€™s end, a markedly different cartographic image of the inhabited world had emerged. Of particular importance for the history of the map was the growth of Alexandria as a major center of learning, far surpassing in this respect the Macedonian court at Pella.
Later geographers used the accounts of Alexandera€™s journeys extensively to make maps of Asia and to fill in the outline of the inhabited world. Not even the improved maps that resulted from these processes have survived, and the literary references to their existence (enabling a partial reconstruction of their content) can even in their entirety refer only to a tiny fraction of the number of maps once made and once in circulation.
It has been demonstrated beyond doubt that the geometric study of the sphere, as expressed in theorems and physical models, had important practical applications and that its principles underlay the development both of mathematical geography and of scientific cartography as applied to celestial and terrestrial phenomena.
On his map, moreover, one could have distinguished the geometric shapes of the countries, and one could have used the map as a tool to estimate the distances between places. To Rome, Hellenistic Greece left a seminal cartographic heritage - one that, in the first instance at least, was barely challenged in the intellectual centers of Roman society. Certainly the political expansion of Rome, whose domination was rapidly extending over the Mediterranean, did not lead to an eclipse of Greek influence. Such knowledge, relating to both terrestrial and celestial mapping, had been transmitted through a succession of well-defined master-pupil relationships, and the preservation of texts and three-dimensional models had been aided by the growth of libraries.
The Romans were indifferent to mathematical geography, with its system of latitudes and longitudes, its astronomical measurements, and its problem of projections. Yet Ptolemy, as much through the accidental survival and transmission of his texts when so many others perished as through his comprehensive approach to mapping, does nevertheless stride like a colossus over the cartographic knowledge of the later Greco-Roman world and the Renaissance. Pilgrims from distant lands obviously needed itineraries like that starting at Bordeaux, giving fairly simple instructions. When we come to consider the mapping of small areas in medieval western Europe, it will be shown that the Saint Gall monastery map is very reminiscent of the best Roman large-scale plans. Some maps, along with other illustrations, were transmitted by this process, but too few have survived to indicate the overall level of cartographic awareness in Byzantine society. Eighty-two places are marked with their respective names, locations of rivers, mountains and forested areas on the map. Experts said that graphics, symbols, scales, locations, longitude and latitude are key elements of a map. Thus in the Ta Tai Li Chi, Tseng Shen, replying to the questions of Shanchu Li, admits that it was very hard to see how, on the orthodox view, the four comers of the earth could be properly covered. Almost at once the two men began to discuss the project for which the scholar had been asked to come from North Africa: the creation of the first accuratea€”and scientifica€”map of the entire known world. After studying in Cordoba, in Muslim Spain, he had spent some years in travel, covering the length of the Mediterranean, from Lisbon to Damascus. His co-religionists, commenting on his oriental life-style, complete with harem and eunuchs, disparagingly referred to him as the a€?half-heathen kinga€? and a€?the baptized Sultan of Sicily.a€? Educated by Greek and Arab tutors, he was an intellectual with a taste for scientific inquiry, and relished the company of Muslim scholars, of whom al-Idrisi was one of the most celebrated.
Like Muslim Spain, it was a beacon of prosperity to a Europe caught in the economic slow-down we call the Dark Ages. In mathematics, as in the political sphere, al-Idrisi wrote of his patron, the extent of his learning cannot be described.
Picturesque and colorful, European maps showed a circular earth composed of three continents equal in sizea€”Asia, Africa and Europea€”separated by narrow bands of water. While medieval Europe had become fragmented and parochial, both politically and commercially, the Muslim world was unified by a flourishing long-distance commerce as well as by religion and culture. The commissiona€™s agents haunted the ports, and if they discovered a traveler who had visited any particularly exotic region, he was conducted to the palace at Palermo to be questioned by al-Idrisi or even by Roger. Then a great disk almost 80 inches in diameter and weighing over 300 pounds was fabricated out of silver, chosen for its malleability and permanence. The great geographer Gerardus Mercator commented, If you wish to sail from one port to another, here is a chart .
A knowledge of this globe would not have come down to our day had not Idrisi, a famous geographer of that time, given an especial description of the same, under the title Nothatol mostak [Pleasure of the Soul].a€? According to other scholars it is more probable that the reference here is to a circular disc or planisphere made by Idrisi, or an armillary sphere, but not to a terrestrial globe.
Following the rough sketch prepared by al-Idrisi, the silversmiths transferred the outlines of countries, oceans, rivers, gulfs, peninsulas and islands to the planisphere.
The planisphere showed the sources of the Nilea€”not explored by Europeans until the 19th century, but evidently known to 12th century Muslim travelersa€”and the cities of central Sudan.
Al-Idrisi described the lost city of Ghana (near Timbuktu, on the Niger) as the most considerable, the most densely peopled, and the largest trading center of the Negro countries.
Few cities are comparable in the solidity and height of buildings, the beauty of the surrounding country, and the fertility of the lands watered by the Tagus.
The Norwegians had to harvest their grain when it was still green and dry it at their hearths since the sun shines very rarely upon them. Because the inhabitants of Africa and Europe waged continual warfare, Alexander decided to separate them by a canal, which he cut between Tangier and al-Andalus (southern Spain). A passionate art collector, Juba was also interested in science and technology, inventing a new method of making purple dye from the orchil plant - and the export of orchil from the Atlantic islands was of economic importance until early this century. But al-Idrisi tells of an attempted expedition to the Canaries in the late 12th century, during the reign of the Almoravid amir Yusuf ibn Tashafin. This is probably Tenerife, and the round mountain would be the 3,600-meter-high (12,000-foot) volcano called Pico de Teide. Eighty men, all ordinary people, got together and built a large ship and stocked it with enough food and water for several months.
The sheep are a problem, for the Azores were uninhabited when settled in the 15th century, and even if we slightly stretch the meaning of the word ghanam, which can also mean a€?goats,a€? we are still left with the problem of the origin of the creatures. There are many rivers and pools, and thickets where donkeys and long-horned cattle take refuge.
There used to be a dragon in the area, and the people were forced to feed it with bulls, donkeys or even humans, according to the legend; when Alexander arrived, the people complained to him of the dragona€™s depredations. Al-Sa€™ali is a word that refers to a kind of female demon or vampire; judging by al-Idrisia€™s description of the female inhabitants of the island, it is apt.
This story of Alexander and the dragon echoes the Eleventh Labor of Hercules, the Golden Apples of the Hesperides, guarded by the dragon Ladon.
It could be argued that the first six islands, spread over three entire climate zones between the equator and the Strait of Gibraltar, represent the six known Canary Islands, forced into this north-south alignment by the physical constraints of the circular map with its narrow band of the Surrounding Ocean.
The first two islands are the Canary Islands, properly shown in the first climate zone and carried forward from Ptolemya€™s map as the Fortunate Islands or Islands of the Blest.
This story may be a borrowing from Greek mythology, where a dragon guarded the golden apples of the Hesperides. In the 1400a€™s, therefore, Christopher Columbus had to rely on other sources of information. Unlike a multitude of Arabic writings of far less intrinsic value, the Rogerian Description found no Gerard of Cremona (translator of Ptolemy into Latin) to put it into Latin, and the authoritative geographical knowledge of the Western world was destined to develop unenriched by the treasures which Roger and Idrisi together had amassed.
Gog and Magog appeared on Arabian maps as Yajoj wa Majoj from the 10th century; they appear on Al-Idrisia€™s map of 1154 under the same names.
The climate numbers are given along the vertical axis, and the ten longitudinal divisions are given across the top. The text was accompanied by 71 part maps, a world map and 70 sectional itinerary maps, representing the seven climates each divided longitudinally into 10 sections. This implies that throughout history maps have been more than just the sum of technical processes or the craftsmanship in their production and more than just a static image of their content frozen in time. The reconstructions of such maps appear in the correct chronology of the originals, irrespective of the date of the reconstruction. After the fall of Byzantium in 1453, its conqueror, the Turkish Sultan Mohammed II, found in the library that he inherited from the Byzantine rulers a manuscript of Ptolemya€™s Geographia, which lacked the world-map, and he commissioned Georgios Aminutzes, a philosopher in his entourage, to draw up a world map based on Ptolemya€™s text.
Comparison of travelersa€™ maps from various periods show the development and change of routes or road-building and allows us to draw conclusions of every kind about the development or decay of farms, villages and towns. They were artistic treasure-houses, being often decorated with fine miniatures portraying life and customs in distant lands, various types of ships, coats-of-arms, portraits of rulers, and so on. The development of the map, whether it occurred in one place or at a number of independent hearths, was clearly a conceptual advance - an important increment to the technology of the intellect - that in some respects may be compared to the emergence of literacy or numeracy. The historian of cartography, looking for maps in the art of prehistoric Europe and its adjacent regions, is in exactly the same position as any other scholar seeking to interpret the content, functions, and meanings of that art. Moreover, there is sufficient evidence for the use of cartographic signs from at least the post-Paleolithic period. They are impressed on small clay tablets like those generally used by the Babylonians for cuneiform inscriptions of documents, a medium which must have limited the cartographera€™s scope. The survey was carried out, mostly in squares, by professional surveyors with knotted ropes.
We find that the Greek geographer Strabo gives us quite a definite word concerning their value and their construction, and that Ptolemy is so definite in his references to them as to lead to a belief that globes were by no means uncommon instruments in his day, and that they were regarded of much value in the study of geography and astronomy, particularly of the latter science. With stress laid, during the many centuries succeeding, upon matters pertaining to the religious life, there naturally was less concern than there had been in the humanistic days of classical antiquity as to whether the earth is spherical in form, or flat like a circular disc, nor was it thought to matter much as to the form of the heavens. Hyde Clarke has more than once pointed out in The Legend of the Atlantis of Plato, Royal Historical Society 1886, etc., that Australia must have been known in the most remote antiquity of the early history of civilization, at a time when the intercourse with America was still maintained.
Between the lower heaven and the surface of the earth is the atmospheric region, the realm of IM or MERMER, the Wind, where he drives the clouds, rouses the storms, and whence he pours down the rain, which is stored in the great reservoir of Ana, in the heavenly ocean. Then in a northeasterly direction Homera€™s great river Okeanos would flow along the shores of the Sandwich group, where the volcanic peak of Mt.
Aristotlea€™s writings, for example, provide a summary of the theoretical knowledge that underlay the construction of world maps by the end of the Greek Classical Period. Our cartographic knowledge must, therefore, be gleaned largely from literary descriptions, often couched in poetic language and difficult to interpret. The ambition of Eratosthenes to draw a general map of the oikumene based on new discoveries was also partly inspired by Alexandera€™s exploration. In this case too, the generalizations drawn herein by various authorities (ancient and modern scholars, historians, geographers, and cartographers) are founded upon the chance survival of references made to maps by individual authors.
Yet this evidence should not be interpreted to suggest that the Greek contribution to cartography in the early Roman world was merely a passive recital of the substance of earlier advances.
If land survey did play such an important part, then these plans, being based on centuriation requirements and therefore square or rectangular, may have influenced the shape of smaller-scale maps. This is perhaps more remarkable in that his work was primarily instructional and theoretical, and it remains debatable if he bequeathed a set of images that could be automatically copied by an uninterrupted succession of manuscript illuminators. While almost certainly fewer maps were made than in the Greco-Roman Period, nevertheless the key concepts of mapping that had been developed in the classical world were preserved in the Byzantine Empire. What is more surprising is that the map marks the location of Wei Shui, now known as the Weihe River, and many canyons in the area. The map of Guixian County has all these elements except longitude and latitude, according to historians. As a young man with poetic pretensions he had written student verse celebrating wine and good company, but in the course of his journeys he had discovered his real passion: geography. The occupying Arabs had built dams, irrigation systems, reservoirs and water towers, introduced new cropsa€”oranges and lemons, cotton, date palms, ricea€”and exploited the islanda€™s mines and fishing grounds. Nor is there any limit to his knowledge of the sciences, so deeply and wisely has he studied them in every particular. The Garden of Eden and Paradise were at the top and Jerusalem at the center, while fabulous monsters occupied the unexplored regionsa€”Sirens, dragons, men with dogsa€™ heads, men with feet shaped like umbrellas with which they protected themselves from the sun while lying down (see #205, #207, #224, #226). The mission he entrusted to al-Idrisi was intellectually Herculean: to collect and evaluate all available geographical knowledgea€”from books and from on-the-spot observersa€”and to organize it into an accurate and meaningful representation of the world. Muslim merchants, pilgrims and officials used so-called a€?road booksa€?, itineraries that described routes, traveling conditions and cities along the way. What was the climate of the country, its rivers and lakes, mountains, coastal configurations and soil? All creatures are stable on the surface of the earth, the air attracting what is light, the earth what is heavy, as the magnet attracts iron. The mathematician al-Khwarizmi reduced Ptolemya€™s estimate of the length of the Mediterranean Sea from 62 to 52 degrees; the Spanish Muslim astronomer al-Zarqali further adjusted the figure to the correct 42 degrees.
Roger II of Sicily had his world map drawn on a six-foot diameter circle of silver weighing about 450 pounds. The Baltic area and Poland were represented much more precisely than on Ptolemya€™s maps, showing the fruit of the geographersa€™ investigations.

In the fourth section of the first climate, al-Idrisi located the sources of the Nile in their approximately correct position, though he pictured the Nile of the Negroes as joining the Egyptian Nile at that point. The gardens of Toledo are laced with canals on which are erected water wheels used in irrigating the orchards, which produce in prodigious quantity fruits of inexpressible beauty and quality. Juba populated the Canaries with Berber-speaking colonists, perhaps the ancestors of the Guanches. The admiral in charge of the expedition died just as it was about to set out, so the venture came to nothing. Then they set sail with the first gentle easterly and sailed for about eleven daya€™s, until they came to a sea with heavy waves, evil-smelling, ridden with reefs and with very little light.
The a€?sea with heavy waves, evil-smelling, ridden with reefs and with very little lighta€? can probably be ignored, for the passage is influenced by the a€?land of darknessa€? thought to exist in the farthest West, and the reefs may echo a passage in Platoa€™s Timeus which speaks of the shallows in the Atlantic marking the site where Atlantis sank. No large mammals are indigenous to the Azores, and sheep or goats could only have been brought to the island by previous mariners. In the Arabic-speaking world, popular legend transferred a number of the heroic deeds of Hercules to Alexander - including the building of a land bridge across the Pillars of Hercules. The wood is deep black, and merchants come to the island to harvest it and then sell it to the kings of the farthest West.
The same linear arrangement of islands appears on 14th century maps such as the 1351Laurentian portolano (Book III, #233), and, a full century later, on the Bartolomeo Pareto map (1455), since it was still impossible to determine longitude. The sixth island, shown opposite the entrance to the Mediterranean, would be al-Ghanam [Island of Sheep], Madeira. I think that Babcock comes close, but, rather than the cormorant, the bird referred to is the goshawk [Afar], a species of hawk that closely resembles an eagle and abounds in the Azores, and from which the entire archipelago gets its name. On the Island of Two Heathen Brothers, two pirates lived until they were turned into rocks, and the inhabitants of the Island of Kalhan had the bodies of men and the heads of animals. Using a globe prepared by a German cartographer named Martin Behaim (Book III, #258), based on Ptolemya€™s miscalculations, Columbus also added in Marco Poloa€™s equally misleading estimates of distances and concluded, incorrectly, that by sailing west from Spain he could reach Japan or India after no more than a 4,000 mile voyage. The consecutive numbers sometimes used to refer to the sectional maps are shown in the upper right corner of each section. Indeed, any history of maps is compounded by a complex series of interactions, involving their intent, their use and their purpose, as well as the process of their making.
All reconstructions are, to a greater or lesser degree, the product of the compiler and the technology of his times. He knew it would be out of date, but that is precisely what he wanted - an ancient map; to perpetuate it, he also had a carpet woven from the drawing. Inferences have to be made about states of mind separated from the present not only by millennia but also - where ethnography is called into service to help illuminate the prehistoric evidence - by the geographical distance and different cultural contexts of other continents. Two of the basic map styles of the historical period, the picture map (perspective view) and the plan (ichnographic view), also have their prehistoric counterparts. However, the measurement of circular and triangular plots was envisaged: advice on this, and plans, are given in the Rhind Mathematical Papyrus of ca. From Ptolemaic Egypt there is a rough rectangular plan of surveyed land accompanying the text of the Lille Papyrus I, now in Paris; also two from the estate of Apollonius, minister of Ptolemy II. There is, however, but one example known, which has come down to us from that ancient day, this a celestial globe, briefly described as the Farnese globe. Yet there was no century, not even in those ages we happily are learning to call no longer a€?darka€?, that geography and astronomy were not studied and taught, and globes celestial as well as armillary spheres, if not terrestrial globes, were constructed.
Here however he makes his hero confess that he is wholly out of his bearings, and cannot well say where the sun is to set or to rise (Od. Although these views were continued and developed to a certain extent by their successors, Strabo and Ptolemy, through the Roman period, and more or less entertained during the Middle Ages, they became obscured as time rolled on.
The bones of the holy apostle were found, with some relics that were placed in a rich vase. Again, if we consider the Atlantic and North Pacific Oceans as devoid of the American Continent, and the Atlantic Ocean as stretching to the shores of Asia, as Strabo did, the parallel of Iberia (Spain) would have taken Columbusa€™ ships to the north of Japan--i.e. At the time when Alexander the Great set off to conquer and explore Asia and when Pytheas of Massalia was exploring northern Europe, therefore, the sum of geographic and cartographic knowledge in the Greek world was already considerable and was demonstrated in a variety of graphic and three-dimensional representations of the heavens and the earth.
In addition, many other ancient texts alluding to maps are further distorted by being written centuries after the period they record; they too must be viewed with caution because they are similarly interpretative as well as descriptive. Eudoxus had already formulated the geocentric hypothesis in mathematical models; and he had also translated his concepts into celestial globes that may be regarded as anticipating the sphairopoiia [mechanical spheres]. And it was at Alexandria that this Ptolemy, son of Ptolemy I Soter, a companion of Alexander, had founded the library, soon to become famous through the Mediterranean world. It seems, though, that having left Massalia, Pytheas put into Gades [Cadiz], then followed the coasts of Iberia [Spain] and France to Brittany, crossing to Cornwall and sailing north along the west coast of England and Scotland to the Orkney Islands. On the contrary, a principal characteristic of the new age was the extent to which it was openly critical of earlier attempts at mapping. Disregarding the elaborate projections of the Greeks, they reverted to the old disk map of the Ionian geographers as being better adapted to their purposes.
This shape was also one which suited the Roman habit of placing a large map on a wall of a temple or colonnade. 90-168), Greek and Roman influences in cartography had been fused to a considerable extent into one tradition. The Almagest, although translated into Latin by Gerard of Cremona in the 12th century, appears to have had little direct influence on the development of cartography.
Ptolemya€™s principal legacy was thus to cartographic method, and both the Almagest and the Geography may be regarded as among the most influential works in cartographic history. However, the maps of Marinus and Ptolemy, one of the latter containing thousands of place-names, were at least partly known to Arabic geographers of the ninth to the 10th century.
The most accomplished Byzantine map to survive, the mosaic at Madaba (#121), is clearly closer to the classical tradition than to maps of any subsequent period. He Shuangquan, a research fellow with the Gansu Provincial Archaeological Research Institute, has made an in-depth study of the map and confirmed its drawing time to be 239 B.C.
He is responsible for singular innovations and for marvelous inventions, such as no prince has ever before realized. His purpose was partly practical, but mostly scientific: to produce a work that would sum up all the contemporary knowledge of the physical world. Other Muslim scholars, like the Iraqi astronomer al-Battani and the Persian al-Biruni (#214.3), composed tables giving the latitudes of leading cities. The works of Al-Idrisi include Nozhat al-mushtaq fi ikhtiraq al-afaq - a compendium of the geographic and sociological knowledge of his time as well as descriptions of his own travels illustrated with over seventy maps; Kharitat al-`alam al-ma`mour min al-ard [Map of the inhabited regions of the earth] wherein he divided the world into seven regions, the first extending from the equator to 23 degrees latitude, and the seventh being from 54 to 63 degrees followed by a region uninhabitable due to cold and snow. The British Isles also were treated with a surprising insight, probably due to contacts between Norman England and Norman Sicily.
It is a considerable island, whose shape is that of the head of an ostrich, and where there are flourishing towns, high mountains, great rivers and plains. Gradually, knowledge of the location of the Canaries was lost, even though Lanzarote, the island nearest the North African coast, lies less than 100 kilometers [60 miles] west of the mainland.
Al-ldrisi says the admirala€™s curiosity was aroused by smoke rising from the sea in the west, probably the result of volcanic activity. Neither name is Arabic, nor do they appear to be transcriptions of Greek, Latin or Romance - but the fact that these two islands had names at all means mariners must have visited them, and the names are either native designations or hark back to some lost, perhaps oral, source. They were sure they were about to perish, so they changed course to the south and sailed for twelve days, until they came to Sheep Island, There were so many sheep it was impossible to count them, and they ranged freely, with no one to watch them. The Azores lie almost 1,300 kilometers (about 800 miles) west of the coast of Portugal - one-third of the way to America. Some Greek mythographers thought the Islands of the Hesperides lay off the coast of North Africa, and we have already seen how al-Idrisi associates Alexander with two of the Atlantic islands. The island is said to have been inhabited in the past, but it fell to ruin and serpents infested the land. Al-Sua€™ali and al-Mustashkin both sound completely legendary, but there is nothing legendary about Hasran and Qalhan, which sound as if they might belong together.
During the period of rediscovery of the Azores under Prince Henry the Navigator, these birds were supposedly responsible for guiding the sailors to these distant islands.
According to one historian, friendly relations were established between the Sultan of Spain and the invaders. Therefore, reconstructions are used here only to illustrate the general geographic concepts of the period in which the lost original map was made. It was said that as the Archangel Gabriel appeared to Zacharias in the holy of holies, Zacharias must have been High Priest and have lived in Jerusalem; John the Baptist would then have been born in Jerusalem. I have not been able to find any such evidence or artifacts of map making that originated in the South America or Australia. This is described in an inscription in the Temple of Der-el-Bahri where the ship used for this journey is delineated, but there is no map.
It is of marble, and is thought by some to date from the time of Eudoxus, that is, three hundred years before the Christian era.
The Venerable Bede, Pope Sylvester I, the Emperor Frederick II, and King Alfonso of Castile, not to name many others of perhaps lesser significance, displayed an interest in globes and making. See the sketch below of an inverted Chaldean boat transformed into a terrestrial globe, which will give an idea of the possible appearance of early globes. Indeed, wherever we look round the margin of the circumfluent ocean for an appropriate entrance to Hades and Tartaros, we find it, whether in Japan, Iceland, the Azores, or Cape Verde Islands. Terrestrial maps and celestial globes were widely used as instruments of teaching and research.
Despite what may appear to be reasonable continuity of some aspects of cartographic thought and practice, in this particular era scholars must extrapolate over large gaps to arrive at their conclusions. By the beginning of the Hellenistic Period there had been developed not only the various celestial globes, but also systems of concentric spheres, together with maps of the inhabited world that fostered a scientific curiosity about fundamental cartographic questions. The library not only accumulated the greatest collection of books available anywhere in the Hellenistic Period but, together with the museum, likewise founded by Ptolemy II, also constituted a meeting place for the scholars of three continents.
From there, some authors believe, he made an Arctic voyage to Thule [probably Iceland] after which he penetrated the Baltic. Intellectual life moved to more energetic centers such as Pergamum, Rhodes, and above all Rome, but this promoted the diffusion and development of Greek knowledge about maps rather than its extinction. The main texts, whether surviving or whether lost and known only through later writers, were strongly revisionist in their line of argument, so that the historian of cartography has to isolate the substantial challenge to earlier theories and frequently their reformulation of new maps.
There is a case, accordingly, for treating them as a history of one already unified stream of thought and practice. With translation of the text of the Geography into Latin in the early 15th century, however, the influence of Ptolemy was to structure European cartography directly for over a century. It would be wrong to over emphasize, as so much of the topographical literature has tended to do, a catalog of Ptolemya€™s a€?errorsa€?: what is vital for the cartographic historian is that his texts were the carriers of the idea of celestial and terrestrial mapping long after the factual content of the coordinates had been made obsolete through new discoveries and exploration. Similarly, in the towns, although only the Forma Urbis Romae is known to us in detail, large-scale maps were recognized as practical tools recording the lines of public utilities such as aqueducts, displaying the size and shape of imperial and religious buildings, and indicating the layout of streets and private property. But the transmission of Ptolemya€™s Geography to the West came about first through reconstruction by Byzantine scholars and only second through its translation into Latin (1406) and its diffusion in Florence and elsewhere. But as the dichotomy increased between the use of Greek in the East and Latin in the West, the particular role of Byzantine scholars in perpetuating Greek texts of cartographic interest becomes clearer. Forested areas marked on the map also tallies with the distribution of various plants and the natural environment in the area today. Others belonged to a later tradition of systematic geography, like the 10th century scholars Ibn Hawqal (#213) and al-Masa€™udi (#212), who produced books intended as something more than practical guides for the tax collector or the postman: as additions to the fund of human knowledge. An element of subjectivity entered into the fact that southern Italy was represented as larger than the north, and that Sicily occupied a substantial part of the Western Mediterranean, in contrast to Sardinia and Corsica, which shrank in scale. This country is most fertile; its inhabitants are brave, active and enterprising, but all is in the grip of perpetual winter. The Greeks called the Canary Islands TA?n MakarA?n NA“soi [The Islands of the Blessed], and they were regarded as the furthest known land to the west.
In another passage al-Idrisi gives more details of this island - incidentally showing that a longer account of the voyage of the mugharrirun must have existed.
In the 19th century, Carthaginian coins were found on the most westerly of the islands, Corvo - 31A° west longitude - and although the find has been questioned, the origin of the coins has never been satisfactorily explained. But if the word is Arabic, one would expect it to be preceded by the definite article a€?ala€?. Since the only inhabited islands in the western Atlantic just before the coming of the Europeans were the Canaries, Hasran may belong to that groupa€”unless, of course, it is to be sought in the Caribbean! If the isle of Raqa is indeed one of the Azores, then the discovery of these islands occurred as early as the 10th century. No one person or area of study is capable of embracing the whole field; and cartographers, like workers in other activities, have become more and more specialized with the advantages and disadvantages which this inevitably brings.
Nevertheless, reconstructions of maps which are known to have existed, and which have been made a long time after the missing originals, can be of great interest and utility to scholars. It has been shown how these could have appealed to the imagination not only of an educated minority, for whom they sometimes became the subject of careful scholarly commentary, but also of a wider Greek public that was already learning to think about the world in a physical and social sense through the medium of maps. The relative smallness of the inhabited world, for example, later to be proved by Eratosthenes, had already been dimly envisaged. The confirmation of the sources of tin (in the ancient Cassiterides or Tin Islands) and amber (in the Baltic) was of primary interest to him, together with new trade routes for these commodities. Indeed, we can see how the conditions of Roman expansion positively favored the growth and applications of cartography in both a theoretical and a practical sense. The context shows that he must be talking about a map, since he makes the philosopher among his group start with Eratosthenesa€™ division of the world into North and South. Here, however, though such a unity existed, the discussion is focused primarily on the cartographic contributions of Ptolemy, writing in Greek within the institutions of Roman society. In the history of the transmission of cartographic ideas it is indeed his work, straddling the European Middle Ages, that provides the strongest link in the chain between the knowledge of mapping in the ancient and early modem worlds. Finally, the interpretation of modem scholars has progressively come down on the side of the opinion that Ptolemy or a contemporary probably did make at least some of the maps so clearly specified in his texts.
Some types of Roman maps had come to possess standard formats as well as regular scales and established conventions for depicting ground detail. In the case of the sea charts of the Mediterranean, it is still unresolved whether the earliest portolan [nautical] charts of the 13th century had a classical antecedent. Byzantine institutions, particularly as they developed in Constantinople, facilitated the flow of cartographic knowledge both to and from Western Europe and to the Arab world and beyond. In addition, scientific expeditions were dispatched to areas on which information was lacking.
Contrary to a still popular misconception that up to the time of Columbus everyone believed the world was flat, many scholars and astronomers since at least the fifth century B.C. Not surprisingly, the best part of both map and text, accurate and detailed, dealt with Sicily itself. It forms an island 300 miles long by 150 miles wide: this is surrounded by the Nile on all sides and at all seasons .
Al-Idrisi gave the names of many English towns, principally ports, with the distances between them. They caught some of the sheep and slaughtered them, but the flesh was so bitter they could not eat it. He says Sheep Island is large, shrouded in shadows, and filled with small sheep whose flesh is bitter and inedible.
Corvo is marked on the Canterino map of 1351, where the name occurs as Corvini - considerably before its official discovery. The possibilities include those for which specific information is available to the compiler and those that are described or merely referred to in the literature. Some saw in the a€?hill countrya€™ Hebron, a place that had for a long time been a leading Levitical city, while others held that Juda was the Levitical city concerned. The fact that King Sargon of Akkad was making military expeditions westwards from about 2,330 B.C. The whole northern region, of sea as he supposed it, from west to east, was known to him only by Phoenician reports. If a literal interpretation was followed, the cartographic image of the inhabited world, like that of the universe as a whole, was often misleading; it could create confusion or it could help establish and perpetuate false ideas. It had been the subject of comment by Plato, while Aristotle had quoted a figure for the circumference of the earth from a€?the mathematiciansa€? at 400,000 stades; he does not explain how he arrived at this figure, which may have been Eudoxusa€™ estimate. It would appear from what is known about Pytheasa€™ journeys and interests that he may have undertaken his voyage to the northern seas partly in order to verify what geometry (or experiments with three dimensional models) have taught him. Not only had the known world been extended considerably through the Roman conquests - so that new empirical knowledge had to be adjusted to existing theories and maps - but Roman society offered a new educational market for the cartographic knowledge codified by the Greeks. Ptolemy owed much to Roman sources of information and to the extension of geographical knowledge under this growing empire: yet he represents a culmination as well as a final synthesis of the scientific tradition in Greek cartography that has been highlighted in this introduction.
Yet it is perhaps in the importance accorded the map as a permanent record of ownership or rights over property, whether held by the state or by individuals, that Roman large-scale mapping most clearly anticipated the modern world.
If they had, one would suppose it to be a map connected with the periploi [sea itineraries]. Our sources point to only a few late glimpses of these transfers, as when Planudes took the lead in Ptolemaic research, for example. Draftsmen and cartographers accompanied these expeditions so that a visual record of the country could be made. The greater part of the country is only habitable on the borders of the Nile for the rest of the country .
Hastings was a considerable town, densely populated, with many buildings, markets, much industry and commerce; Dover, to the east, was an equally important town not far from the mouth of the river of London, the broad and swiftly flowing Thames. In 1402 the Normans partially conquered them, meeting stiff resistance from the indigenous Guanches. They took some sheepskins and sailed on to the south for another twelve days until they sighted an island. Nearby is another island, called Raqa, which is the home of a red bird the size of an eagle, which catches fish in its claws and never flies far from the island.
Certain adventures of Sinbad the Sailor, from Tales of the Arabian Nights, are almost identical to those of Saint Brendan. Viewed in its development through time, the map is a sensitive indicator of the changing thought of man, and few of these works seem to reflect such an excellent mirror of culture and civilization.
Of a different order, but also of interest, are those maps made in comparatively recent times that are designed to illustrate the geographical ideas of a particular person or group in the past but are suggested by no known maps. Many solutions to this problem were put forward, but it was solved once and for all by the Madaba map, which showed, between Jerusalem and Hebron, a place called Beth Zachari: the house of Zacharias. The paucity of evidence of clearly defined representations of constellations in rock art, which should be easily recognized, seems strange in view of the association of celestial features with religious or cosmological beliefs, though it is understandable if stars were used only for practical matters such as navigation or as the agricultural calendar. The celestial globe had reinforced the belief in a spherical and finite universe such as Aristotle had described; the drawing of a circular horizon, however, from a point of observation, might have perpetuated the idea that the inhabited world was circular, as might also the drawing of a sphere on a flat surface.
Aristotle also believed that only the ocean prevented a passage around the world westward from the Straits of Gibraltar to India.
The result was that his observations served not merely to extend geographical knowledge about the places he had visited, but also to lay the foundation for the scientific use of parallels of latitude in the compilation of maps. Many influential Romans both in the Republic and in the early Empire, from emperors downward, were enthusiastic Philhellenes and were patrons of Greek philosophers and scholars. In this respect, Rome had provided a model for the use of maps that was not to be fully exploited in many parts of the world until the 18th and 19th centuries.
But in order to reach an understanding of the historical processes involved in the period, we must examine the broader channels for Christian, humanistic, and scientific ideas rather than a single map, or even the whole corpus of Byzantine cartography. You may get there sooner or you may not get there as soon as you expected, but you will certainly get there.
In the mid-15th century, the Spanish took control of the Canaries and continued the conquest.
The settlers quickly burned down all the forests, so it is now hard to know for certain, but some sort of scented wood may have once grown there.
But whether the Irish borrowed these myths from the Arabs, or vice versa, or if they both obtained them from an earlier common source is a matter of conjecture. The maps of early man, which pre-date other forms of written communication, were attempts to depict earth distributions graphically in order to better visualize them; like those of primitive peoples, the earliest maps served specific functional or practical needs. Excavations on this site revealed the foundations of a little church, with a fragment of a mosaic that contained the name a€?Zachariasa€?. What is certainly different is the place and prominence of maps in prehistoric times as compared with historical times, an aspect associated with much wider issues of the social organization, values, and philosophies of two very different types of cultures, the oral and the literate.
Later we encounter itineraries, referring either to military or to trading expeditions and provide an indication of the extent of Babylonian geographical knowledge at an early date.
Another of a land, also in the north, where a man, who could dispense with sleep, might earn double wages, as there was hardly any night. There was, however, evidently no consensus between cartographic theorists, and there seems in particular to have been a gap between the acceptance of the most advanced scientific theories and their translation into map form. Viewed in this context, some of the essential cartographic impulses of the 15th century Renaissance in Italy are seen to have been already active in late Byzantine society.
Al-Idrisia€™s silver disk, or planisphere, was a form of projection considerably in advance of others of its time. Fighting was still going on when Columbus used the islands as the first stop on all four of his voyages to the Caribbean. They headed toward it in order to explore and when they were not far offshore, they suddenly found themselves surrounded by boats, which forced their ship to land beside a city on the shore.
A king of the Franks heard of this, al-Idrisi adds, and sent a ship to the island to bring him that fruit and some of the birds, but the ship was lost and never returned.
Maps were also frequently used purely for decoration; they furnished designs for Gobelins tapestries, were engraved on goblets of gold and silver, tables, and jewel-caskets, and used in frescoes, mosaics, etc. They do not go so far as to record distances, but they do mention the number of nights spent at each place, and sometimes include notes or drawings of localities passed through. He probably had the first account from some sailor who had visited the northern latitudes in summer; and the second from one who had done the like in winter. The influence of these views on Chinese cartography, however, remained slight, for it revolved around the basic plan of a quantitative rectangular grid, taking no account of the curvature of the eartha€™s surface. The Guanches were not finally subdued until the end of the 16th century, when they and their language virtually disappeared. They saw the men who lived there; they were light-complexioned, with very little facial hair. It was not until the 18th century, however, that maps were gradually stripped of their artistic decoration and transformed into plain, specialist sources of information based upon measurement.
As in Greek and Roman inscriptions, some documents record the boundaries of countries or cities.
At the same time Chinese geography was always thoroughly naturalistic, as witness the passage about rivers and mountains from the LA? Shih Chhun Chhiu.
And in the ninth century, 70 Muslim scholars, working under the patronage of Caliph al-Maa€™mun, gathered in the Syrian Desert to determine the length of a degree of latitude. There are arid wastes where one must walk two, four, five, or twelve days before finding water . From the few words of Guanche preserved in the Spanish chronicles, we know they spoke a form of Berber, and were therefore probably descended from Jubaa€™s colonists. Rather than rely on travelersa€™ guesses of distance, as previous astronomers had done, they used wooden rods to measure the road they traveled until they saw a change of one degree in the elevation of the polestar. Yet when Europeans encountered them, they had no memory of the mainland; having no boats, they were unaware that the other islands in the group were inhabited.
Their calculation resulted in a figure for the eartha€™s circumference equivalent to 22,422 miles, an error of 3.6 percent, almost as accurate as Eratosthenesa€™ estimate and a considerable improvement over Ptolemya€™s. On the fourth day a man who spoke Arabic entered and asked them who they were and where they were going and what was the name of their country.
They told him everything and he said not to worry, and that he was the kinga€™s interpreter. The next day they were taken into the kinga€™s presence and he asked the same questions they had been asked by the interpreter.
They told him what they had told the interpreter the day before, of how they had embarked upon the ocean in order to find out about it and see the wonders it contained, and how they had come to this place.
When dawn broke and the sun rose, we found we were in great pain because we had been so tightly bound. One of them asked us: a€?Do you know how far you are from your country?a€™ a€?No,a€™ we answered.
