Kronos, known to the Romans as Saturn, was a Titan who was the son of Uranus and Gaia and the father of Zeus, Hera, Poseidon, Hades, Hestia, Demeter, and Chiron by his wife Rhea. He overthrew his father and ruled during the mythological Golden Age, but his father and mother warned him that he would one day be overthrown by his own sons. He responded by eating his children, but Rhea saved their child Zeus and hid him on Crete while giving Kronos a stone to eat in his place. Zeus used an emetic to force Kronos to vomit up his siblings, and, in the Titanomachy, Kronos' children, based on Mount Olympus, overthrew the Titans. Kronos and the other Titans were then imprisoned in Tartarus, but his association with the Golden Age led to Kronos being celebrated by Hellenists as a patron of the harvest in Athens.
