For this war against the giants Odin has bestowed upon his son three precious objects, which in the inventory of the Ases appear under the name of Thor’s Three Jewels. The first is his weighty hammer.
Mjoïner (some people call it his club), which goes forth by itself to meet giants and crushes their heads. One of the commentators upon the Edda professes to see in the giants of the mountains nothing but the mountains themselves, and in the hammer Mjoïner, nothing but lightning, which generally strikes their summit. We must evidently put as little faith in commentators as in astronomers.
The second of Thor’s jewels was a pair of iron gloves. As soon as he puts them on, his spear no sooner reaches the point at which it is aimed, than it returns to his hand, precisely as the falcon comes back to the keeper’s gauntlet, after having destroyed its victim.
The third jewel of Thor is his war belt; when he puts it on, his strength is twice as great as before; in fact, he becomes irresistible and would overthrow the great Odin himself. But Odin has nothing to fear on his part, for in spite of his brutal and passionate temper, Thor is always an obedient and submissive son.
Asa-Thor, that is to say, the Lord Thor, was most highly respected among men as the redhaired master of thunder and lightning, and as the destroyer of giants; and he was also greatly feared as an active, blustering god, of a troublesome, turbulent temper and of somewhat eccentric manners.
Another weapon, at least as marvelous as Asa-Thor’s famous hammer, was the sword of the god Freyr. This sword was endowed with an intelligence very rarely to be met with among swords, and punctually obeyed the orders of its master. Even in his absence, it went promptly and faithfully to carry out his orders, striking here and there at a given point, or making terrible havoc in the midst of a battle, without a hand at the hilt to direct its mortal blows.
