Hop as light as bird from brier;
And this ditty after me
Sing, and dance it trippingly.”
Midsummer-Night’s Dream (Shakespeare).
These elves, like the brownies, Huldra folk, kobolds, etc., were also supposed to visit human dwellings, and it was said that they took mischievous pleasure in tangling and knotting horses’ manes and tails. These tangles were known as elf-locks, and whenever a farmer descried them he declared that his steeds had been elf-ridden during the night.
Alf-blot
In Scandinavia and Germany sacrifices were offered to the elves to make them propitious. These sacrifices consisted of some small animal, or of a bowl of honey and milk, and were known as Alf-blot. They were quite common until the missionaries taught the people that the elves were mere demons, when they were transferred to the angels, who were long entreated to befriend mortals, and propitiated by the same gifts.
Many of the elves were supposed to live and die with the trees and plants which they tended, but these moss, wood, or tree maidens, while remarkably beautiful when seen in front, were hollow like a trough when viewed from behind. They appear in many of the popular tales, but almost always as benevolent and helpful spirits, for they were anxious to do good to mortals and to cultivate friendly relations with them.
Images on Doorposts
In Scandinavia the elves, both light and dark, were worshipped as household divinities, and their images were carved on the doorposts. The Norsemen, who were driven from home by the tyranny of Harald Harfager in 874, took their carved doorposts with them upon their ships. Similar carvings, including images of the gods and heroes, decorated the pillars of their high seats which they also carried away. The exiles showed their trust in their gods by throwing these wooden images overboard when they neared the Icelandic shores and settling where the waves carried the posts, even if the spot scarcely seemed the most desirable. “Thus they carried with them the religion, the poetry, and the laws of their race, and on this desolate volcanic island they kept these records unchanged for hundreds of years, while other Teutonic nations gradually became affected by their intercourse with Roman and Byzantine Christianity.” These records, carefully collected by Sæmund the learned, form the Elder Edda, the most precious relic of ancient Northern literature, without which we should know comparatively little of the religion of our forefathers.
