The most powerful of the giants that conspired against Zeus (Jupiter). The king of gods and men cast him down, and threw Mount Etna over him. The poets say that the flames of this volcano arise from the breath of this giant. The battle-field of his contest was Phlegra, in Macedonia.
“So fierce Enceladus in Phlegra stood.”
I tell you, younglings, not Encelados, With all his threatning band of Typhon's brood ... Shall seize this prey out of his father's hands.
