Legends of giants permeate folklore of cultures around the world. The ancient Greeks had Gigantes who were born of Gaia (Earth) when blood from the castrated Uranus (Sky) fell on earth. The Gigantes clashed frequently with the Olympian gods, and those who were vanquished were said to be buried under volcanoes. In Norse mythology, the giants stormed Asgard in the battle of Ragnarök and fought the gods until the world was destroyed. Arguably, the most famous of the giants was Goliath, who was slain by David with a single blow from his slingshot.
