Rh According to Apollodoros, Anaximander was sixty-four years old in Ol. LVIII. 2 (547/6 B.C.); and this is confirmed by Hippolytos, who says he was born in Ol. XLII. 3 (610/9 B.C.), and by Pliny, who assigns his great discovery of the obliquity of the zodiac to Ol. LVIII. We seem to have something more here than a combination of the ordinary type; for, according to all the rules, Anaximander should have "flourished" in 565 B.C., half-way between Thales and Anaximenes, and this would make him sixty, not sixty-four, in 546. Now Apollodoros appears to have said that he had met with the work of Anaximander; and the only reason he can have had for mentioning this must be that he found in it some indication which enabled him to fix its date. Now 547/6 is just the year before the fall of Sardeis, and we may perhaps conjecture that Anaximander mentioned what his age had been at the time of that event. We know from Xenophanes that the question, "How old were you when the Mede appeared?" was considered an interesting one in those days. At all events, Anaximander was apparently a generation younger than Thales.

Like his predecessor, he distinguished himself by certain practical inventions. Some writers credited him with that of the gnomon; but that can hardly be correct. Herodotos tells us this instrument came from Babylon, and Thales must have used it to determine the solstices and equinoxes. Anaximander was also the first to construct a map, and Eratosthenes said this was the map elaborated by Hekataios. No doubt it was intended to be of service to Milesian enterprise in the Black Sea. Anaximander himself conducted
