King Acrisius of Argos imprisons his daughter Danaë, jealous of her beauty. Calibos, the spoiled and rebellious son of the sea goddess Thetis, is betrothed to Princess Andromeda, daughter of Queen Cassiopeia of Joppa; but for committing several atrocities against Zeus, including destroying Zeus’s sacred flying horses, Zeus transforms Calibos into a deformed monstrous satyr-like creature.
