Perseus

Perseus was the son of Zeus and Danae, a princess whose father locked her in a bronze tower after an oracle predicted her son would kill him. Zeus visited Danae as a shower of gold, and Perseus was conceived. Mother and child were cast out to sea in a chest but survived.

When the tyrant Polydectes demanded the head of Medusa as a wedding gift, Perseus embarked on his greatest quest. Athena and Hermes aided him, providing a reflective shield, winged sandals, the cap of invisibility, and an unbreakable sword. Using Athena's shield as a mirror, Perseus approached Medusa without meeting her petrifying gaze and cut off her head.

On his return journey, Perseus spotted the princess Andromeda chained to a rock as a sacrifice to a sea monster. He slew the beast and married Andromeda. Later, at an athletic competition, a discus thrown by Perseus accidentally struck and killed his grandfather Acrisius — fulfilling the prophecy exactly.
