The severed member was thrown into the sea, and Aphrodite emerged from it. Kronos later recieved a prophecy that his children would overthrow him, and therefore, when they were born, he devoured them. When the sixth child, Zeus, was born, Rhea gave Kronos a rock instead, which Kronos thought was Zeus. He ate it, and was finally content. Rhea felt terrible about the children, and Gaea gave her an idea. She fed poison to Kronos, causing him to throw up all the children, who came out fully grown. Soon after, they overthrew their father, and cast him into Tartarus. His children (by Rhea) are: Hestia, Poseidon, Demeter, Hades, Hera, and Zeus.
