The philosopher Cebes has been a native of Thebes and lived in the 5th and 4th centuries BCE, also in Athens of the classical times. He has been a disciple of Socrates and his name appears in works of that period (e.g. Plato and Xenophon). Two other works appear under his name, but they are lost. It is stated that he had been a Pythagorean, because of his discipleship under Philolaus.
The “Tablet” contains a teaching about human life, in the form of a dialogue between an old man and a group of younger persons. The old man explains the paintings (or carvings) on a stone at a Cronos sanctuary, which the young ones cannot figure out. In a few words it is about the way to a happy life; one that comes through true virtue and a soundly developed mind.
For more information you can read here a seemingly exhaustive study around the Cebes’ Tablet, from a moral and religious perspective with many scholarly details as well. The whole book (pdf) is in German language.
