Scandinavian mythology includes light-elves (Lioslfar) who dwell in the third space in heaven, dark-elves (Dcklfar), and black-elves (Svartalfar). The black-elves were skilled smiths, and the most skilled were reputed to be the sons of Ivaldi, the father of Idun.
Little documentation exists on English rustic beliefs and terminology before the nineteenth century, but it seems that the term elf was used, at least on some occasions or in some places, for various kinds of uncanny wights, either human-sized or smaller. But other terms were also used.In Denmark the elves seem to have merged with the Huldra and are beautiful females who can dance a man to death. If you see them from the back, they are hollow.
German folklore held that elves had a particular fondness for children and would appear to those about to die, rather like the Irish banshee. This aspect of the legend was immortalised by Goethe in his poem Der Erlknig, later set to music by Schubert.
The elves of Norse mythology have survived into folklore mainly as females. The lvor (Swedish, singular lva) were stunningly beautiful girls who lived in the forest with an elven king. They were long-lived and light-hearted in nature. They could be seen at night dancing over meadows. The circles they left were called lvdanser (elf dances) or lvringar (elf circles). If a human watched their dance, he would discover that even though only a few hours seemed to have passed, many years had passed in the real world. (This time phenomenon is retold in Tolkien's Lord of the Rings when the Fellowship of the Ring discovers that time seems to have run more slowly in elven Lothlrien. It also has a remote parallell in the Irish sdhe).Elf-shot was the name use for found neolithic flint arrow-heads, imagined as created and used by the elvish folk, and sudden paralysis was sometimes attributed to elf-stroke.
