Rhea gave her newborn son to the nine nymphs that attended his birth (including Hagno), and returned to Mount Orthys. On Crete, in a cave at the base of Mount Ida, Rhea gave birth to her sixth and final child. Claiming that Koios, her clairvoyant brother had advised her to do so, Rhea successfully departed for Crete without any question from Kronos.

A distraught Rhea soon heard the voice of Gaea, advising her to give birth to her final child (who would save his other siblings) on the island of Crete. As a result, Kronos became known as 'King Cannibal.' Rhea pleaded with Kronos to spare their children, but with no success, since even Kronos' great love for Rhea was not enough to overpower his selfish and evil nature.

Hence, determined to retain his place as king, Kronos consecutively swallowed Hestia, Demeter, Hera, Hades and Poseidon as soon as they were born in the fear of being overthrown. All of Zeus's elder siblings had been earlier devoured by Kronos, who was terrified that one of his children (who were gods, a more powerful race of immortals than the Titans) would ultimately overpower him as predicted by his father Ouranos/Uranus before Kronos cut him into pieces. Zeus was the youngest child of Kronos, the Titan King of Mount Othrys, and his sister-wife Rhea. 14.1 Percy Jackson and the Olympians: The Lightning Thief.1.5 Becoming the King of the Olympian Gods.1.3 Rescuing the Elder Cyclopes and Hekatonkheires.
