Background Mythology
Perseus (Greek: Περσεύς) was the legendary founder of Mycenae and one of the earliest mythological Greek heroes. He was famous for killing the Gorgon Medusa. He was the son of Zeus and Danae, daughter of the King of Argos. After his exploits, he would be the father of the Perseid dynasty, which at four generations included Amphitryon, Alcmene, Heracles, and Iphicles.
