Picus, the son of Saturn and father of Faunus, was a woodland divinity, gifted with prophetic powers.

An ancient myth relates that Picus was a beautiful youth, united to a nymph called Canens. The sorceress Circe, infatuated by his beauty, endeavoured to secure his love, but he rejected her advances, and she, in revenge, changed him into a woodpecker, under which form he still retained his powers of prophecy.

Picus is represented as a youth, with a woodpecker perched upon his head, which bird became henceforth regarded as possessed of the power of prophecy.
