1 Anaximenes was:

  • the son of Eurystratus, a Milesian
  • a pupil of Anaximander

Some say that he was also a pupil of Parmenides.

He said that:

  • the principles of everything were the air, and the Infinite.
  • the stars moved not under the earth, but around the earth.

He wrote in the pure unmixed Ionian dialect.

According to Apollodorus, he:

  • lived in the 63rd Olympiad
  • died about the time of the taking of Sardis.

2 There were 2 other persons named Anaximenes, both citizens of Lampsacus:

  • an orator
  • a historian, who was the son of the sister of the orator, and who wrote an account of the exploits of Alexander.

3-4 He wrote the following letters:

ANAXIMENES TO PYTHAGORAS.

Thales, the astronomer of Miletus, 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 out of his house with his maid-servant, to observe the stars but he fell in a precipice and died.

But we, his pupils will lecture on his principles. At all events, the beginning of all wisdom ought to be attributed to Thales.

ANAXIMENES TO PYTHAGORAS

You are more prudent. You have migrated from Samos to Crotona, and live there in peace. The descendants of Æacus commit unheard-of crimes. Tyrants oppress the Milesians.

The king of the Medes too is formidable unless we choose to become tributary to him.

But the Ionians are on the point of engaging in war with the Medes for universal freedom.

If we remain quiet there is no longer any hope of safety for us. How then can Anaximenes apply his mind to the contemplation of the skies, while he is in perpetual fear of death or slavery?

But you are beloved by the people of Crotona, and by all the rest of the Italians; and pupils flock to you, even from Sicily.
