 A motif of father-against-son conflict was repeated when Cronus was confronted by his son, Zeus. Because Cronus had betrayed his father, he feared that his offspring would do the same, and so each time Rhea gave birth, he snatched up the child and ate it. Rhea hated this and tricked him by hiding Zeus and wrapping a stone in a baby's blanket, which Cronus ate. When Zeus was full grown, he fed Cronus a drugged drink which caused him to vomit, throwing up Rhea's other children and the stone, which had been sitting in Cronus's stomach all along. Zeus then challenged Cronus to war for the kingship of the gods. At last, with the help of the Cyclopes (whom Zeus freed from Tartarus), Zeus and his siblings were victorious, while Cronus and the Titans were hurled down to imprisonment in Tartarus.
