Perseus

Perseus (Greek: Περσεύς), the legendary founder of Mycenae and of the Perseid dynasty of Danaans there, 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 the Greek hero who killed the Gorgon Medusa, and claimed Andromeda, having rescued her from a sea monster sent by Poseidon in retribution for Queen Cassiopeia declaring that her daughter, Andromeda, was more beautiful than the Nereids.
