Eudoxus of Cnidus
Plutarch gives a more detailed description on the Greek philosophers who visited Egypt and received advice by the Egyptian priests in his book "On Isis and Osiris". Thus, Thales of Miletus, Eudoxus of Cnidus, Solon, Pythagoras, (some say Lycurgus of Sparta also) and Plato, traveled into Egypt and conversed with the priests. Eudoxus was instructed by Chonupheus of Memphis, Solon by Sonchis of Saïs and Pythagoras by Oenuphis of Heliopolis.
