Transitions in religious traditions over such long periods of time may make some strange turns. Gorgons are often depicted as having wings, brazen claws, the tusks of boars, and scaly skin. The oldest oracles were said to be protected by serpents and a Gorgon image was often associated with those temples. Lionesses or sphinxes are frequently associated with the Gorgon as well. The powerful image of the Gorgon was adopted for the classical images and myths of Athena and Zeus, perhaps being worn in continuation of a more ancient religious imagery. In late myths, the Gorgons were said to be the daughters of two sea deities: Keto, the sea monster, and Phorcys, her brother-husband.
