Saturn/Chronos in Mythology

Cronus was the ruling Titan who came to power by castrating his Father Uranus. His wife was Rhea. There offspring were the first of the Olympians. To insure his safety Cronus ate each of the children as they were born. This worked until Rhea, unhappy at the loss of her children, tricked Cronus into swallowing a rock, instead of Zeus. When he grew up Zeus would revolt against Cronus and the other Titans, defeat them, and banish them to Tartarus in the underworld.

In Greek mythology, Chronos in pre-Socratic philosophical works is said to be the personification of time. He emerged from the primordial Chaos. He is often mythologically confused with the Titan Cronus. He was depicted in Greco-Roman mosaics as a man turning the zodiac wheel. Often the figure is named Aeon (Eternal Time), a common alternate name for the god. His name actually means "Time", and is alternatively spelled Khronos (transliteration of the Greek), Chronos, Chronus (Latin version). Some of the current English words which show a tie to khronos/chronos and the attachment to time are chronology, chronic, and chronicle.
