Elf. An elf is a type of humanoid supernatural being in Germanic mythology and folklore.
Elves appear especially in North Germanic mythology, being mentioned in the Icelandic Poetic Edda and Snorri Sturluson's Prose Edda. In medieval Germanic-speaking cultures, elves generally seem to have been thought of as beings with magical powers and supernatural beauty, ambivalent towards everyday people and capable of either helping or hindering them.
However, the details of these beliefs have varied considerably over time and space and have flourished in both pre-Christian and Christian cultures. Sometimes elves are, like dwarfs, associated with craftmanship.
Wayland the Smith embodies this feature. He is known under many names, depending on the language in which the stories were distributed.
The names include Völund in Old Norse, Wēland in Anglo-Saxon and Wieland in German. The story of Wayland is also to be found in the Prose Edda. The word elf is found throughout the Germanic languages and seems originally to have meant 'white being'. However, reconstructing the early concept of an elf depends largely on texts written by Christians, in Old and Middle English, medieval German, and Old Norse. These associate elves variously with the gods of Norse mythology, with causing illness, with magic, and with beauty and seduction. After the medieval period, the word elf tended to become less common
