III. He also was the first discoverer of the gnomon; and he placed some in Lacedæmon on the sun-dials there, as Phavorinus says in his Universal History, and they showed the solstices and the equinoxes; he also made clocks. He was the first person, too, who drew a map of the earth and sea, and he also made a globe; and he published a concise statement of whatever opinions he embraced or entertained; and this treatise was met with by Apollodorus, the Athenian. IV. And Apollodorus, in his Chronicles, states, that in the second year of the fifty-eighth Olympiad, he was sixty-four years old. And soon after he died, having flourished much about the same time as Polycrates, the tyrant, of Samos. They say that when he sang, the children laughed; and that he, hearing of this, said, “We must then sing better for the sake of the children.” V. There was also another Anaximander, a historian; and he too was a Milesian, and wrote in the Ionic dialect. LIFE OF ANAXIMENES. I. Anaximenes, the son of Eurystratus, a Milesian, was a pupil of Anaximander; but some say that he was also a pupil of Parmenides. He said that the principles of everything were the air, and the Infinite; and that the stars moved not under the earth, but around the earth. He wrote in the pure unmixed Ionian dialect. And he lived, according to the statements of Apollodorus, in the sixty-third Olympiad, and died about the time of the taking of Sardis. II. There were also two other persons of the name of Anaximenes, both citizens of Lampsacus; one an orator and the other a historian, who was the son of the sister of the orator, and who wrote an account of the exploits of Alexander. III. And this philosopher wrote the following letters:— ANAXIMENES TO PYTHAGORAS. Thales, the son of Euxamias, has died in his old age, by an unfortunate accident. In the evening, as he was accustomed to do, he went forth out of the vestibule of his house with his maid-servant, to observe the stars: and (for he had forgotten the existence of the place) while he was looking up towards the skies, he fell down a precipitous place. So now, the astronomer of Miletus has met with this end. But we who were his pupils cherish the recollection of the man, and so do our children and our own pupils: and we will lecture on his principles. At all events, the beginning of all wisdom ought to be attributed to Thales. IV. And again he writes:— ANAXIMENES TO PYTHAGORAS.
