Cebes
Cebes of Thebes (Greek: Κέβης, gen.: Κέβητος; c. 430 – 350 BCE) was an Ancient Greek philosopher from Thebes remembered as a disciple of Socrates. One work, known as the Pinax (Πίναξ) or Tabula, attributed to Cebes still survives, but it is believed to be a composition by a pseudonymous author of the 1st or 2nd century CE.
Life
Cebes was a disciple of Socrates and Philolaus, and a friend of Simmias of Thebes. He is one of the speakers in the Phaedo of Plato, in which he is represented as an earnest seeker after virtue and truth, keen in argument and cautious in decision. Xenophon says he was a member of Socrates' inner circle, and a frequent visitor to the hetaera, Theodote, in Athens. He is also mentioned by Plato in the Crito and Epistle XIII.
Three dialogues, the Hebdome, the Phrynichus, and the Pinax or Tabula, are attributed to him by the Suda and Diogenes Laërtius. The two former are lost, and most scholars deny the authenticity of the Tabula on the ground of material and verbal anachronisms.
