The story of the word

In the Odyssey Menelaus is told he must ambush Proteus while the old sea god sleeps among the seals, hold on through every shape he takes, lion, serpent, water, tree, and only then will he answer a question. That is the whole force of the word: not merely changeable, but evasive under pressure. The name may come from πρῶτος, first, though the ancients themselves were unsure.
