Saturn, who was the previous king of the gods, began to swallow the children that he had with his wife,(Greek equivalent Rhea), when they were born. This was because he had been warned that one of his children would overthrow him. Saturn swallowed the children Neptune, Pluto, Ceres, Juno and Vesta. When Ops realised that she was pregnant with Jupiter, she had the baby secretly and moved to Crete, giving a stone wrapped in baby clothes to Saturn for him to eat. Saturn believed he had eaten Jupiter but Jupiter was saved.
