Thor was one of the most worshipped Norse gods. He was god of thunder and lightning, justice and war, harmony and order in the universe, agriculture, crops and fruitful fields.
He had a hammer of gold called Midnir, that returned to him like a bomerangm with which he threw thunder and lightning. To hold the hammer, he had to have iron gauntlets and he also had a strength increasing belt. He rose in a chariot pulled by two goats, Toothnasher and Toothgrinder.
His parents were Odin and Frigg. He was married to Sif, and had a son called Magni. He lived in the Paddocks and Power, in a castle called Bilskirnir, or lightning. As the patron of people, he was an extremely popular god and before Christianity, oaths were sworn on Thor's hammer and this symbol was worn by people as a protective charm.
He was a wielder of great 'natural' magic and was once considered to be chief of all gods. About 3, 500 years ago in India, they called him Indra. He loved to fight giants and monsters.
This red-headed god appeared as a wild, menacing, roaring, violent force (copied straight from the book too :) that swept through the sky surrounded by crashing thunder and lightning flashes. He was an untidy, big-eating god who often acted first, thought last.
In the Battle of Ragnarok, Thor was fighting the Midgard Serpent, hurling thunderbolts at it. He then hit it in the head with his hammer and a venomous smoke came out of it's mouth. It died, but the smoke also choked and killed Thor.
Thor is still remembered today, and if you didn't know it, Thursday was named afterhim: Thor's day.
