E is for Enceladus
|Taken from here|
During the battle between the Gigantes and the Olympian gods, Athena hit Enceladus with a spear and proceeded to crush him beneath the island of Sicily, so that he lay beneath Mount Etna. It is said that his breath feeds the fires of Mount Etna, and he causes volcanic tremors when he rolls his injured side beneath the volcano.
Other versions of the story say that Zeus killed Enceladus with a flash of lightning, and then buried him underneath the volcano.
