Thor

Snorri Sturluson calls Thor the foremost of the Æsir after Odin and the strongest of all gods and men. His father is Odin and his mother is Jörð, whose name means 'Earth' and whom Snorri counts among the goddesses; his wife is Sif, his sons are Magni and Móði, and his daughter is Þrúðr. He rules Þrúðvangar, 'fields of strength', where his hall Bilskirnir has five hundred and forty rooms. Two goats, Tanngnjóstr and Tanngrisnir, draw his chariot, which is why he is also called Öku-Þórr, 'Driving Thor'.
He owns three treasures. The hammer Mjölnir, forged by the dwarves Brokkr and Eitri, never misses and returns to his hand when thrown. The belt of strength, megingjarðar, increases his divine strength by half when he buckles it on. He cannot do without the iron gloves when he grips the hammer's shaft. Most of his myths are fights with giants: he recovers the stolen hammer by going to the giant Þrymr dressed as Freyja, fishes up the World Serpent with an ox head for bait, and at Ragnarök kills the serpent, walks nine steps and falls dead from its venom.
No other Norse god is as well attested outside the manuscripts. Runestones in Denmark and Sweden ask him to hallow them: the Glavendrup stone on Funen, carved around 900 to 950, reads 'May Thor hallow these runes', and the Velanda stone in Västergötland ends with the same prayer. The Kvinneby amulet from Öland, usually dated to the eleventh century, is generally read as asking Thor to protect its owner with his hammer, and hammer pendants are among the commonest Viking-Age amulets. Personal names built on his, such as Þorsteinn, Þórólfr and Þórdís, outnumber those formed from any other god's name, both in Landnámabók and in the runic inscriptions. Around 1075 Adam of Bremen described Thor, 'the mightiest of them', enthroned in the middle of the temple at Uppsala between Wodan and Fricco, ruling the air, thunder and lightning, wind and rain, fair weather and crops. Thursday is still his day.
The sources say little about how he looked. Snorri's Prologue gives Tror, whom it identifies with Thor, hair fairer than gold, while Icelandic sagas of the thirteenth and fourteenth centuries, among them Eiríks saga rauða, the sagas of Olaf Tryggvason and Flóamanna saga, picture him as a big, red-bearded man. No source gives him a horned helmet, and no Viking-Age battle helmet yet found has horns.
