Ephialtes- Greek GiantGiant

The Aloadae

Ephialtes and his twin Otus were sons of Poseidon by Iphimedeia, wife of Aloeus. In the Odyssey, Homer calls them the tallest and handsomest men the earth nourished after Orion. By the age of nine they measured nine fathoms tall and nine cubits broad, and they were still growing. They piled Ossa on Olympus and Pelion on Ossa to build a stairway to the gods.

In the Iliad, Homer adds what they did to Ares. The twins seized the war god and crammed him into a bronze jar. He stayed there for thirteen months. Hermes learned of it from Eriboea, the giants' stepmother, and stole Ares free. The ordeal had nearly broken him.

Death

Homer says the twins would have stormed heaven had they reached manhood, but Apollo destroyed them before their beards grew. Apollodorus gives a different account: Artemis appeared between the brothers in the form of a deer, and both hurled their spears at the same instant. Each struck the other.

In the Underworld, Homer describes them bound back to back against a pillar, serpents coiled around them.
