There can be no doubt that before the time of Eratosthenes the ideas of the learned world on the subject of geography had assumed a more regular and systematic form. It appears indeed from repeated statements of Strabo that Eratosthenes made it the object of his special attention to a€?reform the map of the world,a€? as it had existed down to his time, and to reconstruct it upon more scientific principles. With regard to the fundamental idea of all geography - the position and figure of the earth - Eratosthenes adopted the views that were current among the astronomers of his day, which had been received almost without exception from the times of Aristotle (ca. But Eratosthenes had the merit of making one valuable addition to the previously existing ideas upon this subject, by a more careful and successful measurement than had ever been previously attempted, of the magnitude of the earth, or circumference of the terrestrial globe. The method pursued by Eratosthenes was theoretically sound, and was in fact identical in principle with that which has been adopted by astronomers in modern day.
While still keeping to the geocentric views of the universe, Eratosthenes started from the assumption that the sun was so distant that for practical purposes one could consider its rays parallel anywhere on earth. The only theoretical error in this mode of calculation was in the assumption - which was inevitable in the days of Eratosthenes - that the earth was exactly spherical, instead of being as it really is, a slightly oblate spheroid, and that therefore a meridian great circle was equal to that of the equator. In the first place, it was assumed that Syene lay directly under the tropic, it being a well-known fact that at the summer solstice the sun could be seen from the bottom of a deep well, and that at the same time the gnomon cast no perceptible shadow. It is remarkable that while the terrestrial measurement was thus grossly inaccurate, the observation of latitude as deduced from the gnomon at Alexandria was a very fair approximation to the truth: a fiftieth part of a great circle being equivalent to an arc of 7A°12a€™, thus exceeding by about 7a€™ only the true interval between Alexandria and Syene, while falling short of that between Alexandria and the real Tropic by about 30a€™ or half a degree. It appears indeed almost certain that Eratosthenes himself was aware of the imperfection of his data, and regarded the result of his calculation only as an approximation to the truth. After all it must be admitted that the calculation of Eratosthenes, considering the disadvantages under which he labored, came surprisingly near the truth. Once the value of 252,000 stades was accepted, it was feasible also to work out the circumference of any parallel circle. Having thus laid the foundation of what has been called in modern times a€?geodesya€? - the determination of the figure and dimensions of the earth, considered in its entirety, as a part of the system of the universe, Eratosthenes next proceeded to consider that portion of it which was in his time geographically known, or supposed to be inhabited.
In his Geographica Eratosthenes discussed the best method of drawing a map of the inhabited area of the earth as known.
Therefore, as with earlier map construction, the length of the oikumene greatly exceeds the width, though by what proportion depends on how much of the northern, eastern and southern extremities were regarded as inhabited.
As approximations to sizes and shapes of parts of the world, Eratosthenes first divided the inhabited world by a line stretching from the Pillars of Hercules [Straits of Gibraltar] to the Taurus Mountains and beyond, then subdivided each of these two sections into a number of irregular shapes, or sphragides, which literally meant a€?an official seala€™ and later was extended to represent a plot of land numbered by a government surveyor, then by extrapolation to a numbered area on a map. Eratosthenes undoubtedly conceived, in accordance with the prevalent belief in his day, that the Ocean was found immediately to the east of India, and that the Ganges flowed directly into it. From that point he supposed the coast to trend away towards the northwest, so as to surround the great unknown tracts of Scythia on the north, but sending in a deep inlet to the south, which formed the Caspian Sea. His ideas of the geographical position and configuration of India were also in great measure erroneous. Physical geography, in the modern sense of the term, was still quite in its infancy in the days of Eratosthenes, and it cannot be said that he did much to impart to it a scientific character. Eratosthenes also adopted, and apparently developed at considerable length, an idea first suggested by the physical philosopher Strabo, that the Mediterranean and the Euxine [Black] Seas had originally no outlet, and stood in consequence at a much higher level, but that they had burst the barriers that confined them, and thus given rise to the Straits of the Bosphorus, the Hellespont and that of the columns. This map of the known world was a very striking achievement and may be considered to be the first really scientific Greek map. Description: The Globe of Euphrosynus Ulpius, constructed in 1542, is now preserved in the museum of the New York Historical Society, having been found in Madrid by Buckingham Smith.
It will doubtless prove of interest to note upon this map the line running from pole to pole and cutting through the border of South America. The Ulpius globe is 15.5 inches in diameter, and is supported upon a worm-eaten stand of oak, the iron cross tipping the North Pole, making the height of the instrument three feet and eight inches. The literal translation is as follows: Regions of the Terrestrial globe handed down by ancients, or discovered in our memory or that of our fathers. This may be rendered: Marcellus Cervino, Cardinal-Presbyter and Doctor of Divinity of the Holy Roman Church. This work is of great historical interest, for the reason that it bears direct and independent testimony to the voyage of Verrazano in 1524, certified first by the Letter of Verrazano to Francis I, confirmed by Carli, and attested to by the map of Hieronimo da Verrazano (#347); this witness being followed by the author of the Discourse of the Dieppe Captain, in 1539. The present representation of one hemisphere of the globe, without being a facsimile, is nevertheless sufficiently correct for historical purposes, and may be relied upon. It will be observed that Ulpius does not give the exact date of the discovery by Verrazano. In the northwest, near Alaska, is Tagv Provincia, the Tangut of Marco Polo, the coast, once again, being joined to Asia.
The Ulpius globe corrects many errors of preceding geographers, though not free from errors itself.
Perhaps the most surprising thing on the globe is to find that the portion of North America above Florida is called Verrazana sive Nova Gallia [Verrazano or New France].
The names scattered along the coast of North America in Ulpiusa€™ delineation of it, are practically all of them of Italian form and termination, though many of them are evidently adaptations of place names well known in France. In Brazil the aborigines appear in the scant wardrobe that they were accustomed to affect, and display, on the whole, what may be regarded as an animated disposition. No true indication of the terminus of the continent of South America is given, but south of the Straits of Magellan is seen a vast continent spreading around the pole.
In the more easterly portion of this continent is written, Terra Australis adhuc incomperta, being an unexplored region, while in passing around the border of this continent we come to Brasieeli, a corruption of a€?Brazil,a€? a name earlier applied to an island in the Atlantic before the discovery of America. The Old World is depicted substantial1y as it appeared in the re-constructed Ptolemaic maps of this period.
Near the bank of the Nile a robed ecclesiastic sits upon a canopied throne with a triple crown upon his brow and a triple cross in his hand. The Conger eel, without much regard to the proprieties, stretches complacently over several degrees of latitude, herein following the example of the gold fish (Aurata), which puffs itself up to half the size of the whale. The fish represented upon the globe are so well done that they might claim a full and separate treatment, evidently belonging to the earliest scientific delineations in Ichthyology.
Besides the historic groups of islands, there are also many of lesser note, together with a few not found today. Bermuda is prominent, having been laid down for the first time on Martyra€™s map of 1511, and southward is Catolica, possibly an alternate name for the a€?Island of the Seven Cities,a€? which was reported in various places, the inhabitants being a€?good Catholics.a€? Near this spot, on Ruyscha€™s map of 1508 (#313), is the word Cata. It would not, however, be proper to treat all these islands of Ulpius now missing in accordance with the volcanic theory. Turning to the Greenland section of the globe, a gratifying improvement upon Verrazanoa€™s outline is found, showing that Ulpius had consulted the maps of Ruysch, 1508 (#313), and Orontius Fines, 1531 (#356), though it will be well to remember in this connection that Behaima€™s globe of 1492 shows land in the same direction. It will be necessary next to speak of the coast names on the North American continent, though it has been indicated previously that certain of them show an agreement with the names on the Verrazano map. In 1612 he made a seventeen daysa€™ journey into the wilderness from Montreal to find the sea upon whose shore Vignan professed to have seen the wreck of an English ship. As mentioned above, the globe is further interesting for illustrations of many different kinds of fish that are found in the different oceans.
It also serves to show how deeply interested were the Popes and the high ecclesiastics near them at Rome in securing and diffusing the best available scientific information. Lithograph facsimile of the Ulpius Globe, Western Hemisphere, 1542, New York Historical Society, 23 cm from Dr. More symmetrical than accurate, its partitions were the forerunners of parallels and meridians after DicA¦archus (#111). And it is certain also that these had been embodied in the form of maps, which, however imperfect, were unquestionably very superior to anything that had preceded them.
It is this enlarged and philosophical view of the subject that constitutes his special merit, and entitles him to be justly called as the a€?parent of scientific geographya€?. Once the idea of a spherical earth was accepted, and that it was a perfect sphere, the measurement of this body was a logical step, even to Greek scholars who were more given to philosophical speculation than to quantification and experimentation. The method pursued by Eratosthenes is fully stated and explained by the astronomer Cleomedes, in his work on the Circular Motion of the Heavenly Bodies.
He observed that the rays of the sun, at midday, at the time of the summer solstice, fell directly over Syene [modern-day Aswan] and that the vertical rod of the sun dial (gnomon or style) would not cast a shadow (predicated on the assumption that Syene was situated exactly under the Tropic of Cancer). But, though these facts were perfectly correct as matters of rough observation, such as could be made by general travelers, they were far from having the precise accuracy requisite as the basis of scientific calculations.
Hence, as mentioned above, he felt himself at liberty to add 2,000 stades to the 250,000 obtained by his process, in order to have a number that would be readily divisible into sixty parts, or into degrees of 360 to a great circle. His measurement of 250,000 stades (the immediate result of his calculation) would be equivalent to 25,000 geographical miles, while the actual circumference of the earth at the equator falls very little short of 25,000 English miles.
Thus Eratosthenes calculated that the parallel at Rhodes, 36A°N., was under 200,000 stades in circumference. And here it must be observed that the relation between the habitable world, which was alone regarded as coming within the scope of the geographer (properly so called), and the terrestrial globe itself, was, in the days of Eratosthenes, and even long afterwards, a very different one from that which we now conceive as subsisting between them. The first task of the geographer therefore, according to the notions then prevailing, was to determine the limits and dimensions of the map of the world, which was to form the subject of his special investigations.
India he suggested drawing as a rhomboid; Ariana [the eastern part of the Persian Empire] would be illustrated as approximating a parallelogram. Just to the north of the Ganges the great mountain chain of Imaus, which he regarded as the continuation of the Indian Caucasus and the Taurus, descended (according to his ideas) to the shores of the Eastern Ocean; and he appears to have given the name of Tarnarus to the headland which formed the termination of this great range. Of the northern shores of Asia or Europe he had really no more knowledge than Herodotus (#109), but, unlike that historian, he assumed the fact that both continents were bounded by the Ocean on the north; a fact which is undoubtedly true, but in a sense so widely different from that supposed by Eratosthenes that a can hardly be held as justifying his theory.
As mentioned above, he conceived it to be of a rhomboidal form, which may be regarded as a rough approximation to the truth, and he even knew that the two sides, which enclosed the southern extremity, were longer than the other two. In treating the mountain chains of Asia as one continuous range, to which he applied the name of Taurus, he may be regarded as having made a first attempt, however crude, at that systematic description of mountain ranges to which we now give the name of orography. In proof of this theory he alleged the presence of marine shells far inland in Libya, especially near the temple of Jupiter Ammon, and on the road leading to it, as well as the deposits and springs of salt that were also found in the Libyan deserts. Although the dimensions are not known exactly, as it was presented to the Egyptian court a may be assumed to have been fairly large. This important and deeply interesting instrument was discovered in the collections of a Spanish dealer in 1859, and brought to New York the same year, after the death of its owner, being purchased for the society by John David Wolfe.
Ulpius, in 1542 stands as the fifth witness to the voyage by the following inscription: Verrazana sive Nova Gallia a Verrazano Florentino comperto anno Sal.
The Old and New Worlds are represented as they were known at the time, the latitude of Florida, which was too high on the Verrazano map (#347), being given quite correctly, while the excessive easterly trend of the North American coast line on that map is corrected. On the North American section of the globe various new points are indicated, and the advance of the Spaniards in New Mexico is noticeable.
The peninsula of Lower California does not appear, though exploration had been extended to that region, as proved by Domingo del Castello, on his map of 1541 (Lorenzana Historia de Nueva Espana, 1770). This is a reference to the a€?Seven Cities of Cibola,a€? which were credited with such vast wealth, it being declared that the houses were supported by massive pillars of crystal and gold. The name of America had been reserved for South America for the better part of half a century, at least for over thirty years, from the time of Canon WaldseemA?llera€™s map in 1507 (#310), which followed the descriptions given in the notes of Amerigo Vespuccia€™s voyages. For the first time the peninsula of Florida receives a proper location and the shore of North America generally is rather well outlined. This, it is noted, was discovered by Verrazano, the Florentine, in the year of grace (anno salutis), 1524. Breton, for instance, is mentioned, but there is a Selva de Cervi [a forest of deer or stags]; there is, of course, a San Francisco and a Porto Reale [Port Royal], and then there is a Terra Laboratoris, evidently what was later to be Labrador, but Ulpius, following Verrazano, places this very much farther south than our present-day Labrador. From the Straits of Magellan to Chinca, just north of the Tropic of Capricorn, the coast is marked Terra Incognita. A couple of Brazilians, broad ax in hand, are on the point of taking off a fellow beinga€™s head, while a third, with a knife, is artistically dressing a leg.
With respect to the East Indies, however, a clear improvement is made upon the Verrazano map. Canton is displayed as a collection of houses, near which is a bird, in company with a couple of goats with ears that reach to the ground. Tall ships, laden with the wealth of a€?Ormus and of Ind,a€? move bravely homeward with billowing sails, while light galleys glide around the borders of the newly found lands.
The Kraken of Pontoppidan, or at least what resembles the sea-serpent of Nahant, appears in the Atlantic off South Africa, corrugating his hirsute back.
The fish upon the Ulpius globe bear a close resemblance to those of Rondelatius (Lugduni, 1554).


An island that appears to be a duplicate of Cape Breton that lies eastward of that region, and is called Dobreta. The Greenland section of Ulpius also indicates that the knowledge in possession of the Zeno family at Venice found some expression in Italy before the publication of the Zeno Voyage and Map in 1558. Along the eastern border of the Gulf of Mexico, adjoining Florida, may be seen Rio Del Gato [the Cat River], the Rio de Los Angelos, or [River of the Angels], the P.
As far northward as the coast of the Carolinas, the territory is considered Spanish, while thence to the Gulf of St. The sea and isthmus were copied from Verrazano, and the existence of a body of water in close proximity to the Atlantic was generally believed. This man, who marched before Champlain through the tangled forests, has been called an impostor, and, with a musket leveled at his head, Vignan confessed himself one; yet no doubt he was as much deceived as Champlain, having acted upon the trusted relation of another, a course which he supposed would succeed, and bring him great credit. This globe, surmounted with a cross, remains as a very definite demonstration that the too common impression of Roman ecclesiastical authorities as hampering the progress of science or keeping information away from the people, is one founded entirely on ignorance of the actual conditions. Geographic information that was gathered by Alexander the Great and his successors was the primary source used by Eratosthenes, a scholar with vision large enough to put this information into a logical framework. The first use of world maps by the Greeks had been introduced at a very early period by Anaximander (ca. The materials at his command were still very imperfect, and the means of scientific observation were wanting to a degree which we can, at the present-day, scarcely figure to ourselves; but the methods which he pursued were of a strictly scientific character, and his judgment was so sound that he proved in many instances to be better informed and more judicious in his inferences than geographers of two centuries later.
He was not indeed the first who had attempted the solution of this problem, which would naturally engage the attention of astronomers and geometers, as soon as it was agreed that the earth was of a spherical form. Both the method and the accuracy of Eratosthenesa€™ well-known measurement of the earth have evoked the admiration of later workers, and his calculation is regarded as one of the greatest achievements of Greek science. Syene is in fact situated in latitude 24A° 5a€™ 30a€?, or nearly 37 miles to the north of the Tropic. Ever since the discoveries of the great Portuguese and Spanish navigators in the 15th and 16th centuries opened out to us new continents, and extensions of those already known, far beyond anything that had previously been suspected or imagined, men have been accustomed to regard the a€?map of the worlda€? as comprising the whole surface of the globe, and including both the eastern and western hemispheres, while towards the north and south it is capable of indefinite extension, until it should reach the poles, and is in fact continually receiving fresh accessions. This question, which was taken up by Eratosthenes at the beginning of his second book, had already been considered by several previous writers, who had arrived at very different results. Rather than a rectangle, he thought of the oikumene as tapering off at each end of its length, like a chlamys [short Greek mantle]. In fact the conclusion of Eratosthenes was mainly based upon the erroneous belief that the Caspian communicated with the Ocean to the north in the same manner that the Persian Gulf did to the south; a view which was adopted by all geographers for a period of three centuries, on the authority of Patrocles. Yet the erroneous idea of its communication with the Ocean to the north sufficiently shows how questionable the information possessed by the Greeks really was. But as he supposed the range of Imaus that bounded the country to the north to have its direction from west to east, while the Indus flowed from north to south, he was obliged to shift around the position of his rhomb, so as to bring the other two sides approximately parallel to the two thus assumed.
He also arrived at a sound conclusion concerning the causes of the inundation of the Nile, a subject that must naturally have engaged the attention of a geographer resident in Egypt. It must have been drawn as closely as possible to scale, and its influence on subsequent Greek and Roman cartography was tremendous. That nation, according to his decree, was entitled to lands discovered by them west of the line, while the Portuguese were to confine their new possessions to the region east of the line, inscribed, Terminus Hispanis et Lusitanis ab Alexando VI. The resemblance of the globe to that planned by Mercator, 1541, taken with the fact that Mercator and the Italian, Moletius, were in a sense associated, might possibly lead us to inquire whether or not Moletius had any influence in connection with the production of the work of Ulpius. The wheat or barley heads appear to have formed a device in the family arms, as they are given with his portrait, while the Deer form a proper allusion to his name. This part of the continent is called Verrazana, sive Nova Gallia, while on the Verrazano map is found, Ivcatania. Undoubtedly, Verrazano was the first to explore the coast behind which lies this immense geographic region, and yet very little was known of that fact until quite recently.
In the distant northwest of the North American continent there is a Tagu Provincia, which is evidently a reminiscence of previous mapmakers who had used that name.
The giants themselves are wanting, like Raleigha€™s men with heads in their breasts, notwithstanding we are told by Pigafetti and other voyagers that there was a plenty of giants in those days; yet, further north, the chameleon roost upon a broad-leaved plant, and still higher up, one of the tall ostriches, described by Darwin, is trying to exhibit himself, using as a pedestal the house formerly of solid gold. Near by, two other amiable representatives of the tribe are engaged in turning a huge spit, upon which, comfortably trussed up, is another superfluous neighbor, whom the blazing fire is transmuting into an acceptable roast. Its existence was considered probable, for the reason that it seemed to be required in order to maintain the balance of land and water.
Prester John has been regarded as a king in Tibet, but the Portuguese claim that he was a convert to the Nestorian faith in Abyssinia. The whale (Balena) is not so well executed as the rest, and is attended by the dolphin (Orca), also called Marsuin by the French. On globes and maps prior to 1542 may be found a variety of intriguing marine monsters, but correct representations of fish are scarce. Roque is De Ferna Loronha, or Fernando de Noronha, discovered in 1506 by the Portuguese navigator of that name. The French were nevertheless ambitious, and would have founded New France on the central portion of our coast if circumstances had proved more favorable. Lawrence it is French, the rest being Portuguese, as allowed by the general use of Portuguese names.
Often it was represented as lying further to the south, and hence some suppose that what was referred to may have been the Gulf of Mexico. The instrument in question is a Roman production, the design of which may yet be traced to Pope Marcellus himself, who was known for his ability and skill in this kind of work.
He regarded the earth as a sphere, placed in the center of the universe, around which the celestial sphere revolved every twenty-four hours: besides which, the sun and moon had independent motions of their own.
Aristotle refers to the calculation of a€?mathematiciansa€? who had investigated the subject (without naming them) that the earth was 400,000 stades in circumference.
Secondly, Alexandria, instead of being exactly on the same meridian with Syene, lay in fact not less than three degrees of longitude to the west of it: an error of no trifling moment when the distance between the two was assumed as the basis of calculation. Thus was established the basis of a fairly accurate system of coordinates for any sectional mapping of the Mediterranean based upon the Rhodes parallel. With the Greek geographers on the contrary, from Eratosthenes to Strabo, the known or habitable world was conceived as a definite and limited portion of the eartha€™s surface, situated wholly within the northern hemisphere, and comprised within about a third of the extent of that section. On one point indeed they were all agreed, that the length of the habitable world, from west to east, greatly exceeded as breadth, from north to south.
Moreover, Strabo tells us that to the above total of 74,000 stades Eratosthenes, using another mathematical ploy, added 2,000 at each end, to prevent the width being more than half the length. Hence he conceived the projecting angle of India to have a direction towards the southeast instead of the south, and even supposed it to advance farther towards the east than the mouth of the Ganges. On the other hand he stated a strange hypothesis: that the surplus waters of the Euphrates were carried by subterranean channels to Coele, Syria, and thence again underground so as to feed the streams which broke out near Rhinocorura and Mount Casius. Indeed, with Ptolemya€™s inaccurate alterations to the overall dimensions of the world and the oikumene, it can be said to have affected world maps right down to the Age of Discovery. Da Costa, in The Magazine of American History (1879), called attention to a reference in Hakluyt to a€?an olde excellente globe in the Queena€™s privie gallery at Westminister which seemeth to be of Verarsanus makinge.a€? On that globe he says the a€?coaste is described in Italiana€? and, as this is the special characteristic of many of the names to be found on this globe, it might possibly seem as though this were the one which Queen Elizabeth I frequently consulted in the privacy of the gallery at Westminster. Everything is done in accordance with the best science of the age, and proves that the globe was intended for careful use. Hakluyta€™s reference to an olde excellent globe in the Queen's privie gallery at Westminster, which seemeth to be of Verarsanus makinge, is also of interest, for, like the globe of Ulpius, it had the Coaste described in Italian, and a necke of lande in the latitude of 40 degrees.
Purchas says that South America was called Peruviana, and North America, Mexicana; which explains the action of Hieronimo da Verrazano in 1529 (#347), who employs the name of Yucatan in accordance with the same principle. The wealth of Cibola eventually became the subject of sport, as was the case respecting the whole continent, at first supposed to be a part of the East Indies, and remarkably auriferous.
His brother published, in 1529, a large map, preserved in the College of the Propaganda at Rome, which outlines Giovanni Verrazanoa€™s discoveries.
Curiously enough, Greenland is pictured not very far from where we know it and under a name not very different from ours, but Islandia is placed very close to the Greenland coast. Gvito, or Quito, happens to be placed nearly in the centre of the South American continent, and close by we read, Domus olim ex solido auri, [the House formerly of solid gold]. The parrot, evidently an edified spectator, gazes placidly down from its perch in the tree. Regio Patalis, a part of this continent, lies southwesterly from the Straits of Magellan, the name perhaps having been transferred from the coast of Africa.
This lonely, harborless isle, with its remarkable peak appears ready to be what it is now, the Sing Sing of Brazil; while St.
An instance is found in the Isle de Fer, a reflection of which, often noticed by sailors, and called the Land of Butter [Terre de beurre], was gravely ceded by the Spanish Government to Louis Perdignon. The editor of the Ptolemy of 1482 knew of the Chronicle of Ivar Bardsen, and some of the names mentioned by him appear upon the editora€™s map; yet at the same time he assigns a false position to Greenland, which is shown as an extension of Norway, while Iceland is laid down in the sea west of what is given as Greenland. 2, 1591) represents the sea in his map, while the Virginia colonists entertained a similar idea. Nevertheless, by whomsoever it may have been designed, this ancient globe has come to us from the Eternal City, finding a permanent resting place at last, not without a certain fine justice, in the great metropolis which looks out upon the splendid harbor visited and described by him whose name is so prominently engraved upon the portion representing the New World.
24, #115) to whom we are indebted for much of our knowledge of geography in antiquity, including the work of Eratosthenes whose relevant works, neither of which have survived, were On the Measurement of the Earth and Geographica, Cleomedes summarized the former, Strabo criticized the latter. The obliquity of the suna€™s course to that of the celestial sphere was of course well known; and hence the great circles of the equinoctial, and the ecliptic, or zodiacal circle, as well as the lesser circles, called the tropics, parallel with the equinoctial, were already familiar to the astronomers of Alexandria. But a much graver error than either of these two was that caused by the erroneous estimate of the actual distance between the two cities. Towards the north and south it was conceived that the excessive cold in the one case, and the intolerable heat in the other, rendered those regions uninhabitable, and even inaccessible to man. Democritus, two centuries before Eratosthenes, had asserted that it was half as long again as it was broad, and this view was adopted by DicA¦archus (#111), though recent discoveries had in his day materially extended the knowledge of its eastern portions. On the parallel of Rhodes, this total of 78,000 stades corresponds to about 140A° longitude, which is roughly the distance from Korea to the west coat of Spain.
He appears in fact to have obtained, probably from the information collected by Patrocles, a correct general idea of the great projection of India in a southerly direction towards Cape Comorin, but was unable to reconcile this with his previously conceived notions as to its western and northern boundaries, and was thus constrained altogether to distort its position in order to make it agree with what he regarded as established conclusions. It would be interesting to trace, at least conjecturally, the possibilities of how the globe found its way over to England.
The latitudes are found by the nicely graduated copper equator, upon which the names of the zodiacal signs are engraved; while the equatorial line of the globe itself has the longitude divided into sections covering five degrees each. What we know as Central America is called Nova Andalusia; the Pacific Ocean is named Mare Pacificum, but also Mare del Sur, which became the familiar South Sea in English, and in South America we find such names as Peru, Bresilia [Brazil], Venazola, Terra Paria, and Rio de Platta. It was doubtless from this that the detailsa€”some of them at leasta€”of the Ulpius globe were secured.
Hibernia [Ireland] has much the form we know and looks like the little dog we see on our maps, but Scotia [Scotland], much less well known at that time, does not extend far enough north, and England is much compressed in length. On a peninsula may be found the following inscription: Lusitani vltra promotorium bone spei i Calicutium tendentes hanc terra viderut, veru non accesserut, quaobrem neq nos certi quidq afferre potuimus [The Portuguese, sailing beyond the Cape of Good Hope to Calcutta, saw this land but did not reach it, wherefore, neither have we been able to assert anything with certainty].
Helena, discovered on the festival of that saint, 1501, is waiting to imprison one of the worlda€™s great disturbers.
To a similar origin may be assigned Jaquet Island, which came from the Jaquet Bank, a shoal near the edge of Grand Bank. The Fata Morgana is perhaps quite as unsatisfactory as the theory of satanic delusion, sometimes resorted to for the purpose of explaining the mystery.
Ulpius, on the contrary, and in accordance with fact, places Iceland east of Greenland, though both are placed too close to mainland Europe. Then follow Selvi di Cervi, the Deer Park of Verrazano, and Calami, similar to the Carnavarall of the Spanish maps.
But for a head wind when off Cape Cod, sailing southward in 1605, Champlain might have reached the Hudson, and instead of planting Port Royal in Nova Scotia, he might have established its foundations on Manhattan Island, in the region where Port Royal (Porto Reale) was laid down by Ulpius. Lawrence River, a belief that led the French to attempt the colonization of that cold and inhospitable country, in preference to the sunny and fertile regions explored farther southward by Verrazano. As late as 1651 the western sea was represented within about two hundred miles of the Atlantic coast, as appears from a map of that year, found in some copies of The Discovery of Nevv Brittaine (see #472). If the history of the globe could be written, it would be found to possess the charms of romance.
Paul Jovius wrote a book on ichthyology, which was published in 1524, but it was not illustrated.


Nor can it be doubted that the discoveries resulting from the conquests of Alexander the Great (ca. Future scholars, however, would have a higher opinion of Eratosthenes, regarding him, a€?as the parent of scientific geographya€? and at least a€?worthy of alphaa€? in that subject, particularly for his remarkable measurement of the circumference of the earth. Moreover it appears that these conceptions, originally applied to the celestial sphere, had been already transferred in theory to the terrestrial globe. What mode of measurement had been resorted to, or how Eratosthenes arrived at his conclusion upon this point, we are wholly without information: but it may well be doubted whether he had recourse to anything like actual menstruation. That there might be inhabitants of the southern hemisphere beyond the torrid zone, or that unknown lands might exist within the boundless and trackless ocean that was supposed to extend around two-thirds of the globe from west to east, was admitted to be theoretically possible, but was treated as mere matter of idle speculation, much as we might at the present day regard the question of the inhabitants on Mars. The astronomer Eudoxus on the other hand maintained that the length was double the breadth; Eratosthenes went a step farther and determined the length to be more than double the breadth, a statement that continued to be received by subsequent geographers for more than three centuries as an established fact. It was doubtless from the same source that he had learned the name of the Coniaci, as the people inhabiting this southernmost point of India; a name that hence forward became generally received, with slight modifications, by ancient geographers. Four distinct meridional lines divide the globe into quarters, while four more lines are faintly indicated. The name Nova Gallia [New France] is not surprising, though that term was applied later to territory farther north than here delineated, and indeed continued to be a favorite geographic designation for Canada and the French possessions until the middle of the 18th century.
The Orkney Islands, under the name of Orcades, are given a very prominent place, thus leaving insufficient room for northern Scotland. The Amazon and the La Platt Rivers appear, but Ulpius does not show any clear knowledge of the Orinoco River seen by Pinzon around 1500. There is also Insvle Tristan Dacvnha, found by the Portuguese, Dacuna, in 1506; and Insvle Formose, while in the southern part of the Indian Ocean is Insvle Grifonvm [the Isle of Griffins].
Here we might pause to remark upon the ease with which islands that have no existence are found in the sea, and the corresponding difficulty of getting rid of them. Mayda is simply the a€?Maidasa€? of the early maps, while the Three Chimnies, if not explained by some eruption, may have originated in such peculiarities of the bottom as that known as the a€?Whale Holea€? on the bank of Newfoundland. The waters of Greenland are represented as navigated, and nothing is perhaps more susceptible of proof than the fact that communication was never lost with Greenland from the tenth century down to the present day.
Perhaps this last one was placed here in honor of Andrea Corsali, the Florentine navigator in the service of Emanuel, King of Portugal, though no record is found of any voyage made by him to this region. This would have made the greatest city in America a French city, and, possibly, changed the destiny of the continent. At the same time the globe, as pointed out, bears the line of Pope Alexander, by which the most of the New World was given to Spain.
The Spaniards, on the same principle, as previously noted, proposed to fortify and colonize the Straits of Magellan.
This error had its day, and then died though not without manifesting a remarkable vitality. This may be the very globe that, as Hakluyt said, a€?seemetk to be of Verrasanus making,a€? and which Queen Elizabeth I was accustomed to consult in the gallery at Westminster. The whale is represented as living in the distant north and is, perhaps, the poorest illustration of all. Thus the idea of the globe of the earth, as it would present itself to the mind of Eratosthenes, or any of his more instructed contemporaries, did not differ materially from that of the modern geographer. But as a mathematical ploy, in order to achieve a number divisible by 60 or 360, so as to correlate stades with his subdivisions or degrees, he emended this to 252,000 stades [a stade, stadion, stadia], originally the distance covered by a plough before turning, was 600 feet of whatever standard was used].
Indeed the difficulty which modern experience has shown to attend this apparently simple operation, where scientific accuracy is required, renders it highly improbable that it was even attempted; and the round number of 5,000 stades at once points to its being no more than a rough approximation. This was the year of the restoration of Catholicism in England under Mary Tudor, and the following year Cardinal Pole became her principal adviser. That line was drawn from pole to pole at ninety degrees west longitude, giving the Portuguese the right over all the territory of Africa, but only a small portion of South America which projects beyond that line. The latitudes are found by the aid of a brass meridian, the Tropic of Cancer being called A†TIVVS, and Capricorn HYEMALIS. The principal adverse critic of Verrazano frankly concedes that the Globe of Ulpius affords indubitable evidence that the maker had consulted the map (Murphya€™s Verrazano).
There is a Terra Gigantum and a Terra de los Fuegos, as well as an immense Terra Australisa€”a great southern continent below the Strait of Magellan (the initium freti Magellanici is carefully noted)a€”but with regard to this southern continent the globe tells us that it had not yet been explored, perhaps not yet actually found, for the Latin words are ad hue incomperta. It was on Verrazanoa€™s discoveries and voyage, authorized and financed by the French king, that the French based their claims to this part of North America. Upon some of our best maps may be found such islands as Jaquet Island, Three Chimnies, Mayda, Amplimont, and Green Rock. Brendana€™s Island, without any great stretch of the imagination, might be referred to as a burning insular peak, so far as the etymology may be concerned; while, again, as the Irish monks were abroad upon the sea at an early period, some of them may have landed upon an island that afterward disappeared.
Ulpius, who seems to copy Ruyscha€™s basic outline, leaves the space between Greenland and the west as unexplored; while Ruysch, on the other hand, makes Greenland, together with Newfoundland, part of Asia, Gog and Magog being in close proximity. These facts, however, are consistent with one another, even on the supposition that the globe was made at the Vatican under the direction of the Cardinal-Presbyter Cervinus. The belief was shared by Ulpius in common with Verrazano, the latter being as positive on the subject as Frobisher himself, both having committed the belief to maps.
Of course, the sea serpent finds a place here, but then the sea serpent has been seen many times, ever since, without scientists being able to locate him. The same thing was the case in ancient times, and it is highly probable that if you could now recover the map of the world as it was generally received in the time of the first Ptolemies, we should find it still retaining many of the erroneous views of Herodotus and HecatA¦us (#109 and #108). For all geographical purposes, at least as the term was understood in his day, the difference between the geocentric and the heliocentric theories of the universe would be unimportant. A conversion to modern units of measure finds Eratosthenesa€™ calculation to be somewhere between 45,007 km (27,967 miles) to 39,690 km (24,663 miles), as compared to actual equatorial circumference of 40,075 km (24,902 miles), there has always been some controversy over the equivalent modern length of a stade as used by Eratosthenes. But even considered as such, it exceeds the truth to a degree that one could hardly have expected, in a country so well known as Egypt, and in an age so civilized as that of the Ptolemies. Through him the globe might easily have found its way into England at this time, and an interesting question would be to trace the relations of friendship between Reginald Pole during his sojourn in Rome and Cardinal Cervinus before he became Pope, so as to discover how this globe could have come into Polea€™s possession and be taken to England. Nevertheless attention has been called to the fact that, in an appendix to his work, the same critic refers to what is called an a€?authority,a€? which says that the map of Verrazano was originated sometime after 1550.
In the case of the monks, it would have received due embellishment, since they were as fond of the marvelous. It remained for the Zeno Map, published sixteen years after the Ulpius globe, to show the position of Greenland more distinctly, and at the same time to reveal the sites of the eastern and western colonies of Greenland, so erroneously supposed in later times to have been situated on the opposite coasts of that country. That person, though loyal to the Papal throne, which he was destined to occupy, was not over friendly to Spain, having three years before refused a pension of ten thousand piastres from Charles V., who wished to win his support.
Lawrence was supposed to lead directly into the a€?Sea of China.a€? When Champlain went to Canada in 1608, he declared that he would not return until he reached that sea.
It certainly went to Spain, and there, the instrument upon which perhaps more than one Pope read the decree of his predecessor, Alexander, was finally banished to the realm of worthless antiquities. Alexandria is in fact situated at a distance of about 530 geographical miles (5,300 stades) from Syene, as measured on the map along the nearest road but the direct distance between the two, or the arc of the great circle intercepts between the two points, which is what Eratosthenes intended to measure, amounts to only 453 miles or 4,530 stades. Even with that problem settled, however, the question as to how the globe found its way back to Spain, would remain. A brass hour-circle enables the student to ascertain the difference of time between any two given points, while the graduated path of the Ecliptic is a prominent and indispensable aid. If this were so, it would appear that the Verrazano map was based upon the Globe of Ulpius in connection with certain maps, and that, instead of having influenced the production of other maps, it is itself a composition made up of early material.
On Coltona€™s Atlas these islands lie in the track of navigation between France and Newfoundland. Germano, both Verrazano names, the former being Longueville, near Dieppe, and the latter St. Therefore, while recognizing the decree of Alexander, he might have been fair with the French, and thus conceded what they had accomplished in the New World by the aid of his countryman, Verrazano. But we have no information as to the data on which these first crude attempts were based, or the mode by which he authors arrived at their results. Eratosthenes, therefore, in fixing the length of this arc at 5,000 stades, was 470 beyond the truth. If there were a replica, one could easily understand that one of the two should find its way there since Marya€™s husband was Philip II of Spain, and he doubtless would have been very much interested in this globe which, better than almost any other map of the time, set forth the Spanish possessions on the other side of the water. It is said that they originated with icebergs in the fog-banks, or possibly in the fog-banks themselves. However this may be, the French are recognized, and the most of the region now occupied by the United States was claimed for France as New Gaul.
But Hakluyta€™s reference is to Elizabeth, perhaps thirty or forty years after Marya€™s death, and when there was no possibility of any such communication between England and Spain as would account for the globe reaching Spanish dominions.
It should be noticed, however, that this part of the ocean is volcanic, and that islands of considerable magnitude have risen from the sea at different times. It stands connected with its maritime enterprise and adventure, and with its naval and geographical romance. The difference in latitude between Alexandria and Syene really amounts to only 7A° 5a€™, so that the direct distance between the two cities, supposing them to have been really situated on the same meridian (as Eratosthenes assumed them to be) would not have exceeded 425 miles or 4,250 stades, instead of 5,000. The earliest eruption on record in the north Atlantic is that mentioned on the Ruysch map in the Ptolemy edition of 1508. Between Iceland and Greenland is the legend Insule hac 1456 anno Dno fvit totaliter combusta [This island was entirely burned up, A.
Especially does it prove to the student how the exploration of our continent tried the courage, tested the endurance, baffled the skill and dissipated the fortunes of some of the noblest of men.
Cartiera€™s voyage of 1534 is not mentioned, as he made no discoveries, but the Gulf of St. Porto Reale follows, when suddenly we reach the river intended for the Penobscot or Norombega, which, as on the Allefonsce map, which is positioned too far south. Ribero on his map (#346) indeed closes the Gulf, yet it was well known to the French at a very early period.
Next is Refvgivm Promont, intended for the Cape of Refuge of the Verrazano map, which afforded Verrazano a land-locked harbor, today identified with Newport, RI.
It must be observed again, however, that the outline of the Ulpius globe is a bit confusing.
The next name is Corte Magiore, unless indeed Magiore belongs with the succeeding inscription. The signification is obscure, like that of Flora, though the latter occurs in several of the Ptolemaic maps of the period, including the Maggiolo map (#340) of 1548, and in Ramusioa€™s Verrazano sketch. Finally, Cavo de Brettoni is reached, or Cape Breton, a name usually referred to the French, but which may have been given by the Portuguese.
The reading may be cdmeri, and thus refer to the Cosin de mer annano, or Oceanus on the SchA¶ner globe of 1520 (#328), signifying the Ocean Cape. With Terra Laboratoris we reach, not Labrador, the Portuguese a€?Land of the Laborers,a€? but Newfoundland. By mistake, Laboratoris is applied to Newfoundland, as later to Cape Breton, the inland waters of which are today called a€?Bras da€™or,a€? previously lengthened from Brador, which, according to the fancy of someone, signified a€?the Arm of Gold,a€? Thus easily are names emptied of their original signification. By mistake, Laboratoris is applied to Newfoundland, as later to Cape Breton, the inland waters of which are today called a€?Bras da€™or,a€? previously lengthened fromA  Brador, which, according to the fancy of someone, signified a€?the Arm of Gold,a€? Thus easily are names emptied of their original signification. Frio [the Cold Cape of the Portuguese] represents Newfoundland, one part of which is marked Terra Corterealis. Yet, whatever name may be given to Newfoundland by the old cartographers, that of Bacca laos always adheres, being derived from Baculum, a stick, often used to keep fish spread open when drying. As in several other maps of the period, the name is repeated on an island lying westward as Grovelat. The greater portion of the region around the Pole is shown as land, but north of Asia is an immense lake, Mare Glaciale, also found on the Nancy globe (#363).
