Damarco (~400 BC), the Dynite, was an Olympic hero of Ancient Greece hailing from Parrasia (Arcadia). Legendary accounts say that this boxer assumed the form of a wolf after a sacrifice to Jupiter Lyceus (epithet of Zeus in Arcadian feasts), returning to human condition nine years after the fact, thus constituting one of the oldest references to lycanthropy.
The name Damarchus comes from the Doric Greek Δάμαρχος (Latin Damarchus) and means alcalde. It is composed of the roots of the words δάμος (people) and άρχος (chief). Its correlate in Attic dialect is Δήμαρχος.
