Proteus
A shape-shifting sea god near Egypt whom Menelaus seizes in the Odyssey to learn the truth of his return.

Overview
Proteus is the sea god of Odyssey Book 4. Eidothea describes him as one who knows the depths of the sea and warns Menelaus that, once seized, he will shift through many forms. Near Egypt, Menelaus follows her instructions, holds him through the transformations, and forces him to reveal the return route, divine anger and the fates of other heroes. Proteus turns sea-knowledge into a test: truth does not appear freely, but must be held through uncertainty with patience, technique and divine help.
