pursuits the world over. To the requests presented even the antipodes have responded.
In concluding, the author might refer to his interest in globes as dating from his early boyhood days, when, in that country school in western Illinois, bearing the name Liberty, for it had been established in the first years of the Civil War, he studied his geography and indeed his astronomy lessons with the aid of a terrestrial globe and an orrery. Can it be that we have revised our educational methods so far in this country as practically to have eliminated the intelligent use of aids so valuable in the study of the branches which globes concern? They enter in fact but little into modern methods of instruction. If this work could be made to encourage their extensive use, and serve in their rehabilitation as aids of inestimable interest and value in geographical and astronomical studies, it will have served the purpose which is most pleasing to the author.

Terrestrial Globes in Antiquity
The beginnings of astronomical and of geographical science.—Primitive attempts at map construction, as seen in the Babylonian plan of the world.—Anaximander probably the first scientific cartographer.—Statements of Herodotus.—The place of Hecataeus, Hipparchus, Marinus, Ptolemy.—The Romans as map makers.—The earliest beliefs in a globular earth.—Thales, the Pythagoreans, Aristotle.—Eratosthenes and his measurements of the earth.—Crates probably the first to construct a terrestrial globe.—Statements of Strabo.—Ptolemy’s statements concerning globes and globe construction.—The allusions of Pliny.
THE beginnings of the science of astronomy and of the science of geography are traceable to a remote antiquity. The earliest records which have come down to us out of the cradleland of civilization contain evidence that a lively interest in celestial and terrestrial phenomena was not wanting even in the day of history’s dawning. The primitive cultural folk of the Orient, dwellers in its great plateau regions, its fertile valleys, and its desert stretches were wont, as we are told, to watch the stars rise nightly in the east, sweep across the great vaulted space above, and set in the west as if controlled in their apparent movement by living spirits. To them this exhibition was one marvelous and awe-inspiring. In the somewhat strange grouping of the stars they early fancied they could see the forms of many of the objects about them, of many of their gods and heroes, and we find their successors outlining these forms in picture in their representations of the heavens on the material spheres which they constructed. Crude and simple, however, were their astronomical theories relative to the shape, the structure, and the magnitude of the great universe in which they found themselves placed.1
Then too, as stated, there was something of interest to the people of that early day in the simple problems of geography; problems suggested by the physical features of their immediate environment; problems arising as they journeyed for trade or traffic, or the love of adventure, to regions now near, now remote. Very ancient records tell us of the attempts they made, primitive indeed most of them were, to sketch in general outline small areas of the earth’s surface, usually at first the homeland of the map maker, but to which they added as their knowledge expanded. The early Egyptians, for example, as we long have known, made use of rough outline drawings (Fig. 1)2 to represent certain features of special sections of their country, and recently discovered tablets in the lower Mesopotamian valley (Fig. 2) interestingly show us how far advanced in the matter of map making the inhabitants of that land were two thousand years before the Christian era.3 We are likewise assured, through references in the literature of classical antiquity, that maps were made by the early Greeks and Romans, and perhaps in great numbers as their civilization advanced, though none of their productions have survived to our day. To the Greeks indeed belongs the credit of first reducing geography and map making to a real science.4 No recent discovery by archaeologist or by historian, interesting as many of their discoveries have been, seems to warrant an alteration of this statement, long accepted as fact.

The credit of being the first scientific cartographer has been generally assigned to the Greek Anaximander of Miletus (610–547 BC).5 While there is not a detailed description extant of the maps he is reputed to have made, we know that he accepted the so-called Homeric idea, that the earth has the form of a circular disc,6 and is surrounded by the Ocean Stream, an idea generally approved by the Ionic School of Philosophers.7 It is not improbable that we have an allusion to the work of Anaximander in the History of Herodotus (484–400? BC), wherein we are told that Aristagoras, the tyrant of Miletus, when on a mission to Cleomenes, the King of Sparta, carried with him “a copper plate on which was engraved the whole circuit of the earth, and likewise all the Seas and Rivers.”8 In another passage, Herodotus takes occasion to criticise maps of this circular character. “I laugh,” he says, “when I see that, though many before this have drawn maps of the Earth, yet no one has set the matter forth in an intelligent way; seeing that they draw the Ocean flowing round the Earth, which is circular as if drawn with compasses, and they make Asia equal in size to Europe. In a few words I shall declare the size of each division and of what nature it is as regards outline.”9 It is, however, interesting to observe that the father of historical geography and of history nowhere records his idea of a properly constructed map, and further that the circular form, which he condemned, is one which found wide acceptance even to the close of the middle ages.
We are not definitely informed as to just the course of improvement or advancement in early scientific map making among the Greeks, yet not a few names are known to us of those who made it a matter of special endeavor, as they specifically stated, to improve the work of their predecessors. We, for example, are told that Hecataeus (550–480 BC),10 likewise a native of Miletus, improved the maps of Anaximander, and that scientists of his day were astonished at his results; that Dicaearchus of Massina (350–290 BC)11 was the first to employ a central line of orientation on a map, one passing through the Mediterranean east and west, and that he represented on his map all the lands known since the expedition of Alexander the Great into the Far East; and further, that Eratosthenes, the librarian of Alexandria (276–196 BC),12 was the first to attempt a representation of the curved surface of the earth on a plane in accord with geometrical rules. The scientific cartographical ideas of Eratosthenes were further developed by Hipparchus (180–125 BC),13 who is generally referred to as the greatest astronomer of antiquity, and by Marinus of Tyre (fl. ca. 100 AD),14 who introduced the idea of inscribing lines of latitude and longitude on a map, crossing
