IV.] MAP-MAKING. 65 describe these features on a level surface, and names appended to explain what was designated by them. The first mention that we meet with of the employment of such a map is in Herodotus, where the historian is Arjsta oras recounting the circumstances of the Ionian revolt and his Map at Quarto 4nnR f* against Persia. Aristagoras, tyrant of Miletus, he tells us, who was the leader of that rising, visited Sparta in order to persuade Cleomenes the king to lend his assistance to their undertaking. In the course of the interview that followed, in order to set forth the advantages to be gained by an expedition against Persia, he described the wealth of the lands which lay between the sea-coast of Asia Minor and that country: and that he might explain this more clearly, he produced "a bronze tablet whereupon the whole circuit of the Earth was engraved, with all its seas and rivers1." On this he pointed out to the king with his finger the position of the different peoples that lay on the way, at the same time descanting on the riches which they possessed. Cleomenes for the time postponed his reply, and at 'their next conference enquired how many days' journey it was from the Ionian sea to Susa. In an incautious moment Aristagoras answered that it was a journey of three months; whereupon Cleomenes, discouraged by the magnitude of the undertaking, at once dismissed him from Sparta. The map that was exhibited on this occasion by the tyrant of Miletus was in all probability an adaptation of that which had been designed by his fellow-countryman Anaximander, and afterwards improved by Hecataeus. A point, the determination of which must have gone some way towards regulating the shape and arrangement of the early maps, was the position of the centre of the Earth's surface. This was fixed at Delphi for the Greeks by religious associations, in the same way as at a later time Jerusalem became the central point of the world in the minds of Dante and his contemporaries. The popular belief on this subject gave rise to the fable which Pindar relates, that two eagles which were let go by Zeus, the one from the east, the other from the west, met at Delphi2.
