In Greek mythology, Enceladus was one of the Giants, the offspring of Gaia (Earth) and Uranus (Sky). Enceladus was the traditional opponent of Athena during the Gigantomachy, the war between the Giants and the gods, and was said to be buried under Mount Etna in Sicily.

In Greek and Roman mythology, the Giants, also called Gigantes, were a race of great strength and aggression, though not necessarily of great size. They were known for the Gigantomachy, their battle with the Olympian gods. According to Hesiod, the Giants were the offspring of Gaia (Earth), born from the blood that fell when Uranus (Sky) was castrated by his Titan son Cronus.
