Folklore is the body of expressive culture, including tales, music, dance, legends, oral history, proverbs, jokes, popular beliefs, customs, and so forth within a particular population comprising the traditions (including oral traditions) of that culture, subculture, or group. It is also the set of practices through which those expressive genres are shared. The academic and usually ethnographic study of folklore is sometimes called folkloristics. The word 'folklore' was first used by the English antiquarian William Thoms in a letter published by the London Journal Athenaeum in 1846.
The term was coined in 1846 by an Englishman, William Thoms, who wanted to use an Anglo-Saxon term for what was then called "popular antiquities." Johann Gottfried von Herder first advocated the deliberate recording and preservation of folklore to document the authentic spirit, tradition, and identity of the German people; the belief that there can be such authenticity is one of the tenets of the romantic nationalism which Herder developed. The definition most widely accepted by current scholars of the field is "artistic communication in small groups," coined by Dan Ben-Amos a scholar at the University of Pennsylvania, and the term, and the associated field of study, now include non-verbal art forms and customary practices.
Sometimes "folklore" is religious in nature, like the tales of the Welsh Mabinogion or those found in Icelandic skaldic poetry. Many of the tales in the Golden Legend of Jacob de Voragine also embody folklore elements in a Christian context: examples of such Christian mythology are the themes woven round Saint George or Saint Christopher. In this case, the term "folklore" is being used in a pejorative sense. That is, while the tales of Odin the Wanderer have a religious value to the Norse who composed the stories, because it does not fit into a Christian configuration it is not considered "religious" by Christians who may instead refer to it as "folklore."
"Folktales" is a general term for different varieties of traditional narrative. The telling of stories appears to be a cultural universal, common to basic and complex societies alike. Even the forms folktales take are certainly similar from culture to culture, and comparative studies of themes and narrative ways have been successful in showing these relationships. Also it is considered to be an oral tale to be told for everybody.
On the other hand, folklore can be used to accurately describe a figurative narrative, which has no sacred or religious content. In the Jungian view, which is but one method of analysis, it may instead pertain to unconscious psychological patterns, instincts or archetypes of the mind. This may or may not have components of the fantastic (such as magic, ethereal beings or the personification of inanimate objects). These folktales may or may not emerge from a religious tradition, but nevertheless speak to deep psychological issues. The familiar folktale, "Hansel and Gretel," is an example of this fine line. The manifest purpose of the tale may primarily be one of mundane instruction regarding forest safety or secondarily a cautionary tale about the dangers of famine to large families, but its latent meaning may evoke a strong emotional response due to the widely understood themes and motifs such as “The Terrible Mother”, “Death,” and “Atonement with the Father.”
There can be both a moral and psychological scope to the work, as well as entertainment value, depending upon the nature of the teller, the style of the telling, the ages of the audience members, and the overall context of the performance. Folklorists generally resist universal interpretations of narratives and, wherever possible, analyze oral versions of tellings in specific contexts, rather than print sources, which often show the work or bias of the writer or editor.
Contemporary narratives common in the Western world include the urban legend. There are many forms of folklore that are so common, however, that most people do not realize they are folklore, such as riddles, children's rhymes and ghost stories, rumors (including conspiracy theories), gossip, ethnic stereotypes, and holiday customs and life-cycle rituals. UFO abduction narratives can be seen, in some sense, to refigure the tales of pre-Christian Europe, or even such tales in the Bible as the Ascent of Elijah to heaven. Adrienne Mayor, in introducing a bibliography on the topic, noted that most modern folklorists are largely unaware of classical parallels and precedents, in materials that are only partly represented by the familiar designation Aesopica: "Ancient Greek and Roman literature contains rich troves of folklore and popular beliefs, many of which have counterparts in modern contemporary legends" (Mayor, 2000).
Vladimir Propp's classic study Morphology of the Folktale (1928) became the basis of research into the structure of folklore texts. Propp discovered a uniform structure in Russian fairy tales. His book has been translated into English, Italian, Polish and other languages. The English translation was issued in USA in 1958, some 30 years after the publication of the original. It was met by approving reviews and significantly influenced later research on folklore and, more generally, structural semantics.
