Xenophon 
The Memorabilia [EPUB ebook] 

Xenophon the Athenian was born 431 B.C. He was a pupil of Socrates. He marched with the Spartans, and was exiled from Athens. Sparta gave him land and property in Scillus, where he lived for many years before having to move once more, to settle in Corinth. He died in 354 B.C.
The Memorabilia is a recollection of Socrates in word and deed, to show his character as the best and happiest of men.
