KronosCronos

One of the Titans, i.e. one of the children of Gaia (Earth) and Ouranos (the Heavens).

Kronos was dethroned by his son Zeus just as Kronos had dethroned his father Ouranos; Kronos and Rheia (Rhea) are best known as the parents of the Olympians: Zeus, Poseidon, Hades, Histia (Hestia), Hera and Demeter.

As each of his children was born Kronos would swallow them so that they could not grow to be adults and threaten his power; finally, when Zeus was born, Rheia substituted a stone for the infant and Kronos swallowed it down thinking that he had devoured the last of his children; Zeus was spirited away and allowed to grow to adulthood.

When Zeus was grown, he ambushed his father and attacked him with such violence that the previous five children were disgorged from Kronos’ stomach; Kronos was forced into the darkness of Tartaros (Tartarus) and the six children became the new rulers of heaven and earth.
