Clement of Alexandria suggests that Plato traveled to Heliopolis (a notion that Strabo also held) and was a disciple of the Egyptian priest Sechnuphis. Plutarch adds the detail that Plato sold oil to the Egyptians while in Egypt to offset his travel expenses. And Strabo suggests that Plato and his travel companion courted the favor of the priests of Heliopolis to “let them learn some of the principles of their doctrines.” We find additional accounts of Plato’s sojourn in Egypt in the writings of Diogenes Laertius and Cicero.
