PERSEUS
Perseus
Perseus, the legendary founder of Mycenae and of the Perseid dynasty of Danaans, was the first of the heroes of Greek mythology whose exploits in defeating various archaic monsters provided the founding myths of the Twelve Olympians. Perseus was a demi-god, the Greek hero who killed the Gorgon Medusa, and claimed Andromeda, having rescued her from a sea monster sent by Poseidon. Cassiopeia declaring that her daughter, Andromeda, was more beautiful than the Nereids is what initially resulted in Andromeda being plagued by Poseidon's sea monster.The above text is a snippet from Wikipedia: Perseus
