The Elder Edda and the Younger Edda/Younger Edda/Thor and His Hammer
22. "I now ask thee," said Gangler, "what are the names of the other gods. What are their functions, and what have they brought to pass?"
"The mightiest of them." replied Har, "is Thor. He is called Asa-Thor and Auku-Thor, and is the strongest of gods and men. His realm is named Thrudvang, and his mansion Bilskirnir, in which are five hundred and forty halls. It is the largest house ever built."
"Thor has a car drawn by two goats called Tanngniost and Tanngrisnir. From his driving about in this car he is called Auku-Thor (Charioteer-Thor). He likewise possesses three very precious things. The first is a mallet called Mjolnir, which both the Frost and Mountain Giants know to their cost when they see it hurled against them in the air; and no wonder, for it has split many a skull of their fathers and kindred. The second rare thing he possesses is called the belt of strength or prowess (Megingjardir). When he girds it about him his divine might is doubly augmented; the third, also very precious, being his iron gauntlets, which he is obliged to put on whenever he would lay hold of the handle of his mallet. There is no one so wise as to be able to relate all Thor's marvellous exploits, yet I could tell thee so many myself that hours would be whiled away ere all that I know had been recounted."
