In Greek mythology, the Gigantes were a race of giants. They were born of Gaia, who was fertiziled by the blood of Ouranos that resulted from his castration by Cronus.
The Gigantes attacked the Olympians in what is known as the Gigantomachia. Led on by Alcyoneus and Porphyrion, the Gigantes hoped to reach the top of Mount Olympus by stacking the mountain ranges of Thessaly, Pelion and Ossa, on top of each other. The Olympians called upon the aid of Heracles after a prophecy warned them that he was required to defeat the Gigante. Heracles slew not only Alcyoneus, but dealt the death blow to the Gigantes who has been wounded by the Olympians.
The Gigantes were Alcyoneus or Alkyonios, Athos, Clytias or Klytias, Enceladus, or Enkelados, Echion, and Pallas.
In Greek mythology, Enceladus was one of the Gigantes, who was defeated in battle by Zeus's thunderbolts and buried under Mount Etna by Athena. Mount Etna's fires were supposed to be the breath of Enceladus, and its eruptions were caused by his rolling his injured side inside the mountain. Some believe that he is the same as Typhon.
