Towards the end of the 20th century, a number of people have begun to describe themselves as elves, usually more of the Tolkien than the folkloric Santa type. Many of these people can be found in the Otherkin subculture.
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 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.The Harry Potter book series by J. K. Rowling features house-elves that resemble brownies or goblins more than modern high-fantasy elves. Rather like the elves in The Shoemaker & the Elves, Rowling's house-elves are released from servitude when they are given clothes.However, in Elizabethan England, Shakespeare imagined elves as little people. He apparently considered elves and fairies to be the same race. In Henry IV, Part 1, i. 4, he has Falstaff call Prince Henry, "you starveling, you elfskin!", and in his Midsummer Night's Dream, his elves are almost as small as insects. On the other hand, Edmund Spenser applies elf to full-sized beings in The Faerie Queene.The Brothers Grimm fairy tale The Shoemaker & the Elves is probably the most famous original elf tale. The elves are only one foot tall in this story, naked, and like to work on shoes, as leprechauns do. When the shoemaker rewards their work with little clothes, the elves are so delighted, that they run away and are never seen again. (This tales is echoed in J. K. Rowling's Harry Potter stories: see below.)The Discworld novels by Terry Pratchett feature extradimensional creatures called elves, that go back to the old myths of cradle-robbing fairies. The book Lords and Ladies is about an encounter with "the fair folk".Tolkien is responsible for reviving the older and less-used terms elves, elven, and elvish rather than Edmund Spenser's invented elfs, elfin, and elfish. He probably preferred the word elf over fairy because elf is of Anglo-Saxon origin while fairy entered English from French.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.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.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.
