Thor or Donar, Thunder, is said to be the mightiest of the gods; he is identified, as we saw, with Jove, but he is a rougher and more primitive deity. He drives in a chariot drawn by two goats, and is possessed of three things which have wonderful properties. The first is the hammer Mjoelnir, which the Frost- and Mountain-giants cannot resist when he throws it; the second is the belt of strength, which makes him twice as strong when he puts it on; and the third a pair of gauntlets with which he grasps his mallet. Many stories are told of his prowess, of his conflicts with the giants, who, however, give him a good deal of trouble with their cunning; and of his catching the Midgard serpent which surrounds the world at the bottom of the sea. Being a god of storm, he forms a connection with agriculture, and thus gains a more sedate aspect; he has also to do with marriage, and a hammer is used symbolically at Icelandic weddings. Thor is only half-brother to the other sons of Odin; his mother was Fioergyn, the earth; the worships of Odin and Thor, originally distinct, seem to have been united at an early period. The god Tyr, son of Odin by a giantess, is the Eddic figure of the German Tiw or Ziu, etymologically equivalent to Zeus or Jupiter, but identified by the Romans with Mars. His greatness belongs to early times; he was then a sword-god, and had an extensive worship in various parts of Europe. In the Eddas he has scarcely any character, and seldom takes a prominent part in the legend. Loki, by etymology a fire-god (Germ. _Loehe_, Scot. _Lowe_),[8] is in one account the brother of Odin, in another his son by a giantess. His character is fitful; sometimes he acts a brotherly part by the gods and helps them out of their difficulties by clever devices, and sometimes he provides entertainment for them; but for the most part he is an embodiment of cunning and mischief; his course is downwards, he tends to become a being purely evil, setting himself heartlessly against the wishes of the other gods, and acting so as to imperil them and their world till they are obliged to cast him out of heaven. He is thus a kind of Lucifer or Satan, and like the Christian devil, his ultimate fate is to be bound till the end of the world shall arrive. Baldur, the son of Odin and Frigga, is the best and brightest of the gods. Like Apollo, he has to do with light, and no pollution can come near him; he has also to do with the administration of justice, and pronounces sentences which can never be reversed. Heimdall also is a light and gracious god; he is the warder of the Aesir, and stays near the bridge Bifroest. Of him it is told that he wants less sleep than a bird, sees a hundred miles off by night or day, and hears the grass grow on the ground and the wool on the sheep's back. Bragi is the god of poetry and eloquence, the best of all skalds.
