Serpents figured prominently in archaic Greek myths. According to some sources, Ophion ("serpent", a.k.a. Ophioneus), ruled the world with Eurynome before the two of them were cast down by Kronos and Rhea. The oracles of the ancient Greeks were said to have been the continuation of the tradition begun with the worship of the Egyptian cobra goddess, Wadjet. We learn from Herodotus of a great serpent which defended the citadel of Athens.
