Plato 
Phaedo 

After an interval of some months or years, and at Phlius, a town of Peloponnesus, the tale of the last hours of Socrates is narrated to Echecrates and other Phliasians by Phaedo the ‘beloved disciple.’ The Dialogue necessarily takes the form of a narrative, because Socrates has to be described acting as well as speaking. The minutest particulars of the event are interesting to distant friends, and the narrator has an equal interest in them.During the voyage of the sacred ship to and from Delos, which has occupied thirty days, the execution of Socrates has been deferred. (Compare Xen. Mem.) The time has been passed by him in conversation with a select company of disciples. But now the holy season is over, and the disciples meet earlier than usual in order that they may converse with Socrates for the last time.
