Perseus was the son of Zeus and a mortal woman.
As a young man, he attended a king’s banquet where the king requested a gift from each of his guests.
Each of the other guests offered a horse.
But Perseus, who was broke, could only offer his services.
The king demanded that Perseus bring him the head of the Gorgon Medusa.
Perseus claimed Andromeda rescuing her from a sea monster sent by Poseidon in retribution for Queen Cassiopeia declaring herself more beautiful than the sea nymphs.
