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 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".
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.
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.Before they became diminutive and whimsical, elves were probably akin to powerful pre-Christian forest spirits like the woodwose, the Green Man, and the drusi in the mythology of the Gauls beings to be respected and even feared. A trace of the former importance of elves in Germanic culture exists in names like Alfred (Old English lfrd, "elf-counsel") and Alvin (Old English lfwine, "elf-friend").In 1954, Poul Anderson introduced grim Norse-style elves in his fantasy novel The Broken Sword and made them full-sized.
