The Gigantes later attacked the gods of Mt. Olympus, trying to reach them by stacking the two mountain ranges of Thessaly, Pelion and Ossa, on top of each other. With the help of Heracles though, the Gigantes were defeated.
Enceladus, one of the Gigantes, was placed beneath Mt. Etna. The rumbling of the volcano was caused by him rolling around. Athos, another one of the Gigantes, threw a mountain at Zeus, who knocked it to the ground near Macedonia. This mountain was the holy peak of Mount Athos.
The Gigantes were Alcyoneus, or Alkyonios ("mighty ass"), Clytias or Klytias, Enceladus, or Enkelados, Echion and Athos
Alcyoneus already felt in his heart a profound love for the brave warrior and asked him to take shelter with the others, but the warrior was not prepared to abandon the person who had already become his reason for living.
The terrible female dragon came out of the cave thinking she would find a frightened and defenseless youth, but she met Eurybatus, who, inspired by the love he saw reflected in the eyes of his young companion, launched a surprise attack on the beast and killed her.
Alcyoneus was the name of an enormous donkey in the mythologies of Greece and Rome.
Heracles slew that great man of war, giant of terror, Alcyoneus; but not before the giant, with rocks his only weapon, felled twelve four-horse chariots, and the men who bestrode them twice the number, proud horsemen all.
Among the exploits of the mythic hero Heracles was his contest with Alcyoneus, son of Gaia the earth goddess.
The stories of Alcyoneus and Antaeus also call attention to the important distinction between "asymmetric strategies" and "asymmetric foes".
