Lycaon was an Arcadian sacred king, and considered the ancestor of all “lycanthropes” or werewolves. His totemic form, of course, was the wolf. He was formerly worshipped in the Lyceum or “wolf-temple” where Aristotle taught.
Lycaon seems to have been an earthly incarnation of several elder gods able to assume the form of a wolf, such as Apollo Lycaeus and Zeus Lycaeus.
