  • Cebes was a citizen of Thebes. Three dialogues of his are extant:

  • Menedemus belonged to Phaedo’s school; he was the son of Clisthenes, a member of the clan called the Theopropidae, of good family, though a builder and a poor man; others say that he was a scenepainter and that Menedemus learnt both trades. Hence, when he had proposed a decree, a certain Alexinius attacked him, declaring that the philosopher was not a proper person to design either a scene or a decree. When Menedemus was dispatched by the Eretrians to Megara on garrison duty, he paid a visit to Plato at the Academy and was so captivated that he abandoned the service of arms.
