Tabula Cebetis (The Table of Cebes)

I have read the book The Table of Cebes" (Κέβητος Πίναξ) many years ago. If my memory serves me good its about a painting that Cebes contributed to a philosophy school (Pythagorean maybe?). The book describes the painting in detail, which is one's journey through life. I had pictured it myself but I didn't know there were actual paintings done in the past. I researched it tonight and found these images! Do some research and read the book. Way better than just looking at a painting.

Wikepedia says The Table of Cebes was probably written pseudonymous author of the 1st or 2nd century.
Any comments or info?
