Phaedo
Socrates offers four arguments for the soul's immortality:The scene is set in Phlius where Echecrates who, meeting Phaedo, asks for news about the last days of Socrates. Phaedo explains why a delay occurred between his trial and his death, and describes the scene in a prison at Athens on the final day, naming those present. He tells how he had visited Socrates early in the morning with the others. Socrates' wife Xanthippe was there, but was very distressed and Socrates asked that she be taken away. Socrates' relates how, bidden by a recurring dream to "make and cultivate music", he wrote a hymn and then began writing poetry based on Aesop's Fables.
Chaerephon
In Plato's "Apology", an account of the Trial of Socrates in 399 BCE, Socrates calls Chaerephon his longtime friend and the friend of many present. Socrates says that Chaerephon is now deceased but indicates that his brother is in attendance at the trial. Socrates suggests that Chaerephon had a reputation for being impetuous and we learn that it was Chaerephon who journeyed to Delphi to ask the Delphic oracle who was the wisest of men. (The oracle replied that there was none wiser than Socrates.) Socrates also alludes to a period of exile which was endured by Chaerephon and some others present. This is sometimes taken as evidence that Chaerephon, unlike Socrates, was an active supporter of the Athenian Democracy and was persecuted on this account when the democracy was temporarily deposed after the defeat of Athens by Sparta.
