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.
Tolkien's The Lord of the Rings (1954-1958), became astoundingly popular and was much imitated. In the 1960s and afterwards, elves similar to those in Tolkien's novels became staple non-human characters in high fantasy works and in fantasy role-playing games (RPGs).
English folktales of the early modern period typically portray elves as small, elusive people with mischievous personalities (see illustration). They are not evil but might annoy humans or interfere in their affairs. They are sometimes said to be invisible. In this tradition, elves became more or less synonymous with the fairies that originated from native British mythology, for example, the Welsh Ellyll (plural Ellyllon) and Y Dynon Bach Tg.
The Scandinavian elves were of human size, which allowed "normal" human interactions: for example, in Hrlf Kraki's saga, the Danish king Helgi finds an elf-woman on an island and rapes her. Famous men could be elevated to the rank of elves after death, and in one such case, the full-sized smith hero Vlund is called an elf.In the Nordic countries where elves have since become associated with Christmas, elves are clad all in red and have long beards and black boots. On Christmas Eve, one must give the elves a bowl of porridge to keep them from playing pranks. In Iceland, from December 12 until Christmas Eve, thirteen elves called the Yule lads visit homes, a lad each day for 13 days, and play tricks on the children, as well as leaving presents for them.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.What remained of the belief in elves in German folklore was that they were mischievous pranksters that could cause disease to cattle and people, and bring bad dreams to sleepers. The German word for nightmare, Albtraum, means "elf dream". The archaic form Albdruck means "elf pressure"; it was believed that nightmares are a result of an elf sitting on the dreamer's chest.Elves are mythical creatures of Germanic mythology that have survived in northern European folklore. Originally a race of minor gods of nature and fertility, they are often pictured as small, youthful-seeming men and women of great beauty living in forests and other natural places, underground, or in wells and springs. They have been imagined to be long-lived or immortal and magical powers have been attributed to them. Something associated with elves or the qualities of elves is described by the adjectives elfin, elven, elfish, or elvish. Elves are staple characters in modern fantasy. They are also called:The term lfsciene ("elf-shining") is used in the Old English poem Judith referring to elven beauty. On the other hand oaf is simply a variant of the word elf, presumably originally referring to a changeling or to someone stupefied by elvish enchantment.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.
