Otis and Ephialtes, the twin giants were together called the Aloadae. These giants are said to have grown every year by one cubit in breadth and three cubits in height. They once threatened to wage a war on gods and attempted to storm Mt. Olympus by piling up mountains. They also threatened to change land into sea and sea into land. Some say they even dared to seek the hand of Hera and Artemis in marriage. Angered by this, Apollo killed them by shooting arrows at them. According to another tale, Apollo killed them with a trick. He sent a deer between them. As they tried to kill it with their javelins, they accidentally stabbed each other and died.
