/**
Son of Poseidon (PERSEUS)

In Greek mythology, Perseus is the legendary founder of Mycenae and of the Perseid dynasty.
He was, alongside Cadmus and Bellerophon, the greatest Greek hero and slayer of monsters before the days of Heracles.
He beheaded the Gorgon Medusa for Polydectes and saved Andromeda from the sea monster Cetus.
He was the son of Zeus and the mortal Danaë, as well as the half-brother and great-grandfather of Heracles.
