And the Gorgoneion amulet (Medusa's face on a plate, and on the shield Aegis) adorning every door in Athens to scare away evil spirits predates all the Perseus stories.

From OSP, I learned about Dread Persephone predating Hades in running the underworld and Aphrodite washing up on Kythira as Astarte (Ishtar) and bringing the alphabet that would replace Linear-B. The Hellenic myths go deep.

Oh and Ishtar might be Asherah, consort to Adonai, id est Yahweh.
