In Greek mythology, Cronus, Cronos, or Kronos was the leader and youngest of the first generation of Titans, the divine descendants of Uranus and Gaia. He overthrew his father and ruled during the mythological Golden Age, until he was overthrown by his own son Zeus and imprisoned in Tartarus. According to Plato, however, the deities Phorcys, Cronus, and Rhea were the eldest children of Oceanus and Tethys.
