In USA, Canada, and the United Kingdom, the modern children's folklore of Santa Claus typically includes diminutive, green-clad elves as Santa's assistants. They wrap Christmas gifts and make toys in a workshop located in the Arctic. In this portrayal, elves slightly resemble nimble and delicate versions of the dwarfs of Norse mythology. However, the elf legends are in fact, even older than Saint Nicholas, the bishop on whom Santa Claus was originally based.
The twentieth-century philologist and fantasy writer J. R. R. Tolkien had little use for Shakepearean fairy portrayals or for Victorian diminutive fairy prettiness and whimsy, aligning his elves with the god-like and human-sized elves of Norse mythology, the Ljoslfar. He conceived a race of beings similar to humans but fairer, with greater spiritual powers, keener senses, and a closer empathy with nature. They are great smiths and fierce warriors on the side of good. Tolkien's Elves of Middle-earth are not deathless and can be killed by injury, and while they are sufficiently long-lived to be called immortal by humans, they do age.
Elves were imported into Britain with the Anglo-Saxons.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).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.
