Balder, says the Edda, dreamed of death. A goddess made everything in nature swear not to hurt him, except a mistletoe plant, which she thought too young to understand the nature of an oath! Loki learned this, plucked the plant, and, when the gods were hurling things at Balder, asked the blind Hödur to throw the mistletoe. It pierced and slew Balder, and his funeral was of a kind which may, or may not, have been used before the period of inhumation in 'howes' or barrows. Balder's dead body was burned on board his ship, 'the hugest of all ships.'[27] I had an impression that this was a not uncommon Viking form of incremation, but Mr. Craigie thinks that it had quite gone out before the historic period. In the legendary period he remembers but one case, in Ynglinga Saga.[28] King Haki, being mortally wounded, had his ship piled with the bodies and weapons of the slain; a funeral pyre was erected on board and lit, and the body of Haki was borne forth to sea in the flaming vessel. 'The thing was famous long after.' The story may be borrowed from the Balder story or the Balder story from that of King Haki. In any case Balder was not sacrificed, but cremated, and the 'huge ship,' of course, is a late Viking idea, an idea the reverse of primitive. Mr. Frazer, however, goes on, apparently assuming that in the original form of the myth Balder was sacrificed, to a theory about certain religious or ritual fires, which survive in folklore. These fires are lit by peasants at various seasons, but are best known at midsummer, while a pretence of burning a man is made, and this at a season when mistletoe is gathered as a magical healing herb, not as a weapon of death. He seems to think that Balder was the spirit of the oak, that human victims, representing the oak and Balder, were, of old, periodically sacrificed, and that people deemed that the oak could not be injured by axes before the mistletoe (in which, they thought, lay its life) was plucked off. Unluckily, I see no evidence that people ever did entertain this opinion--namely, that the oak was invulnerable till the mistletoe was plucked.[29]
