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).
The elves (light-elves) are often mentioned along with the Aesir, instead of the Vanir (a race of gods). The names Vanir and Alfar (light elves) may have been either synonymous, since the expression "Aesir and Alfar" meant "all the gods", or designating a difference in status between the major fertility gods, the Vanir, and the minor ones, the elves. The Van Freyr was the lord of lfheim (meaning "elvenhome"), the home of the light-elves, and he had as servants two elves: Byggvir and Beyla. Like the Vanir the elves were associated with fertility and, in late fall, the "alfablt" (elven sacrifice) was performed in the homes. It was secret, no strangers were allowed in the homes, and so next to nothing is known of it.
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.Elf, fairy, and other terms for nature spirits like pwcca, hobgoblin, Robin Goodfellow, the Scots brownie, and so forth are no longer clearly distinguished in popular English folklore, nor are similar terms in other European languages.Christopher Paolini's Eragon also features elves of a Nordic persuasion.The influence of Shakespeare and Michael Drayton made the use of elf and fairy for very small beings the norm. In Victorian literature, elves usually appeared in illustrations as tiny men and women with pointed ears and stocking caps. There were exceptions, such as the full-sized elves who appear in Lord Dunsany's The King of Elfland's Daughter.Post-Tolkien literary elves (popularized by the Dungeons & Dragons role-playing game) tend to be human-sized or only slightly smaller than humans, and tend also to be capable warriors, especially skilled in archery. Terms like hob or brownie or other genuine regional folklore terms are seldom used of such creatures: they are unlikely to sneak in at night and help a cobbler mend his shoes. The canonical role-playing style elf is Deedlit, a major character of the anime series Record of Lodoss War.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.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.
