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.
Tolkien's elves were enemies of goblins and orcs and had a longstanding quarrel with the dwarves: these motifs also often reappear in Tolkien-inspired works. In gaming, and to some extent fantasy, elves have a great depth of knowledge (especially regarding magic) due to a racial inclination as well as their extreme age. There are also "dark elves" popularized by TSR as drow.
Christopher Paolini's Eragon also features elves of a Nordic persuasion.Tad Williams's Memory, Sorrow, and Thorn trilogy focuses heavily on a long-lived, fair-skinned, magical race known as the Sithi, which are described as elves in all but name.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".Buy elven jewelry online in the largest elvish storeIn 1954, Poul Anderson introduced grim Norse-style elves in his fantasy novel The Broken Sword and made them full-sized.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).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").
