Of the Asa-burgh;
The war-exposed plains
The Vanir trampled on.
A fight is also mentioned in the Ynglinga Saga which seems to be the same as the one referred to in Völuspa.
“Odin went with a host against the Vanir, but they withstood him well and defended their land. Asar and Vanir got the victory by turns; each waged war in the other’s land and plundered. When they became tired of this they appointed a meeting for agreement between themselves, and made peace and gave each other hostages. The Vanir gave their foremost men, Njörd the wealthy and his son Frey, and the Asar gave a man called Hœnir, and said he was well fitted to be a chief. He was a tall and very handsome man. The Asar sent with him a man called Mimir, who was very wise; in exchange for him the Vanir gave one, who was the wisest among them, called Kvasir. When Hœnir came to Vanaheim he was at once made chief; Mimir taught him everything. And when Hœnir was at the Things or meetings, and Mimir was not near, and some difficult cases were taken to him, he always gave the same answer, ‘Let others say what is to be done.’ Then the Vanir suspected that the Asar had deceived them in the exchange of men. They took Mimir and beheaded him, and sent his head to the Asar. Odin took the head and besmeared it with the juice of plants, so that it could not rot. He sang charms over it, and by spells made it so powerful that it spoke with him, and told him many unknown things” (Ynglinga, c. 4).
Thór was one of the greatest of the Norse gods after Odin; indeed, these with Frey formed a sort of triad.
“Thór is the foremost of them (the gods); he is called Asa-Thór or Öku-Thór. He is the strongest of all gods and men. His realm is Thrúdvángar (= plains of strength), and his hall is called Bilskirnir; in it there are 540 rooms. It is the largest house built by men. (See Grimnismal.) Thór owns two he-goats, which are called Tanngnjóst (tooth-gnasher) and Tanngrísnir (tooth-gnasher), and a chariot (reid), on which he drives and the he-goats draw it. Therefore he is called Oku-Thór (= the driving Thór). He also owns three costly things. One of them is the hammer Mjolnir which the Hrim Thursar and Berg Risar know when it is aloft, and that is not strange, for he has broken many a head of their fathers or kinsmen. The next best of his costly things is the belt of strength. When he girds himself with it his Asa-strength doubles. He owns a third thing, which is worth much, iron-gloves, without which he cannot hold the handle of the hammer. No man is so wise that he may reckon up all his great feats, but I can tell thee so many tales of him that the hours will be whiled away before I have told all that I know.”
“Hár said: ‘Furthermore there is an As called Týr. He is the boldest and most daring and has much power over victory in battles. It is useful for valiant men to make vows to him. It is a saying that the one surpassing others in valour and fearing nothing is Tý-brave. He is so wise that the wisest man is called Tý-wise. One of the proofs of his daring is this. When the Asar persuaded the Fenriswolf to allow them to tie it with the chain Gleipnir, it did not believe that they would untie it till they laid Týr’s hand into its mouth as a pledge. When they would not untie it then it bit off his hand at the place now called Wolf-joint (wrist). He is therefore onehanded and said not to be the reconciler of men.’” (Later Edda, Gylfaginning, 21).
The Later Edda differs from the Grimnismal in giving the number of gods or Asar which it mentions. When Gylfi asks how many Asar there are he is told twelve, and the names of Odin, Höd, and Baldr are omitted from the list. Only a few of these gods seem to have been of sufficient prominence to have had sacrifices offered to them, as is seen in the chapter on Religion, and we cannot depend on the Later Edda for reliable information concerning them.
“The Asar went to their feast, and the twelve Asar who were to be judges sat down in the high-seats: their names were—Thór, Njörd, Frey, Týr, Heimdall, Bragi, Vidar, Vali, Ull, Hœnir, Forseti, Loki” (Later Edda).
