Despite these precautions, Danaë was visited by Zeus, the god of gods, who appeared to her in a shower of gold. Danaë and Zeus had a son together, Perseus. When Acrisius discovered that Danaë had given birth, he placed her and Perseus in a wooden chest and cast it into the sea.
The chest drifted until it washed ashore on the island of Seriphos, where Perseus was raised by a fisherman named Dictys. As Perseus grew up, he became a skilled warrior and athlete. One day, he was challenged to compete in a discus-throwing contest, and he accidentally killed Acrisius with a stray throw. Thus, the oracle's prophecy was fulfilled.
Perseus returned to Argos and became king. He later founded the city of Mycenae, which became one of the most powerful city-states in ancient Greece.
