There is much disagreement among scholars as to how to define the folktale; consequently, there is disagreement about the relation between folktale and myth. One view of the problem is that of the American folklorist Stith Thompson, who regarded myths as one type of folktale; according to this approach, the particular characteristic of myth is that its narratives deal with sacred events that happened “in the beginning.” Other scholars either consider folktale a subdivision of myth or regard the two categories as distinct but overlapping. The latter view is taken by the British Classicist Geoffrey S. Kirk, who in Myth: Its Meaning and Functions in Ancient and Other Cultures (1970) uses the term myth to denote stories with an underlying purpose beyond that of simple story-telling and the term folktale to denote stories that reflect simple social situations and play on ordinary fears and desires. Examples of folktale motifs are encounters between ordinary, often humble, human beings and supernatural adversaries such as witches, giants, or ogres; contests to win a bride; and attempts to overcome a wicked stepmother or jealous sisters. But these typical folktale themes occur also in stories normally classified as myths, and there must always be a strong element of arbitrariness in assigning a motif to a particular category.
A different and important aspect of the problem of defining a folktale relates to the historical origin of the concept. As with the notion of folklore, the notion of folktale has its roots in the late 18th century. From that period until the middle of the 19th century, many European thinkers of a nationalist persuasion argued that stories told by ordinary people constituted a continuous tradition reaching back into the nation’s past. Thus, stories such as the Märchen (“tales”) collected by the Grimm brothers in Germany are folktales because they were told by the people rather than by an aristocratic elite. This definition of folktale introduces a new criterion for distinguishing between myth and folktale—namely, what class of person tells the story—but it by no means removes all the problems of classification. Just as the distinction between folk and aristocracy cannot be transferred from medieval Europe to tribal Africa or Classical Greece without risk of distortion, so the importing of a distinction between myth and folktale on the later European model is extremely problematic. Sagas and epics
The word saga is often used in a generalized and loose way to refer to any extended narrative re-creation of historical events. A distinction is thus sometimes drawn between myths (set in a semidivine world) and sagas (more realistic and more firmly grounded in a specific historical setting). This rather vague use of saga is best avoided, however, since the word can more usefully retain the precise connotation of its original context. The word saga is Old Norse and means “what is said.” The sagas are a group of medieval Icelandic prose narratives; the principal sagas date from the 13th century and relate the deeds of Icelandic heroes who lived during the 10th and 11th centuries. If the word saga is restricted to this Icelandic context, at least one of the possible terminological confusions over words for traditional tales is avoided.
While saga in its original sense is a narrative type confined to a particular time and place, epics are found worldwide. Examples can be found in the ancient world (the Iliad and Odyssey of Homer), in medieval Europe (the Nibelungenlied), and in modern times (the Serbo-Croatian epic poetry recorded in the 1930s). Among the many non-European examples are the Indian Mahabharata and the Tibetan Gesar epic. Epic is similar to saga in that both narrative forms look back to an age of heroic endeavour, but it differs from saga in that epics are almost always composed in poetry (with a few exceptions such as Kazak epic and the Turkish Book of Dede Korkut). The relation between epic and myth is not easy to pin down, but it is in general true that epics characteristically incorporate mythical events and persons. An example is the ancient Mesopotamian epic of Gilgamesh, which includes, among many mythical episodes, an account of the meeting between the hero Gilgamesh and Utnapishtim, the only human being to have attained immortality and sole survivor (with his wife) of the flood sent by the gods. Myth is thus a prime source of the material on which epic draws. Legends
In common usage the word legend usually characterizes a traditional tale thought to have a historical basis, as in the legends of King Arthur or Robin Hood. In this view, a distinction may be drawn between myth (which refers to the supernatural and the sacred) and legend (which is grounded in historical fact). Thus, some writers on the Iliad would distinguish between the legendary aspects (e.g., heroes performing actions possible for ordinary humans) and the mythical aspects (e.g., episodes involving the gods). But the distinction between myth and legend must be used with care. In particular, because of the assumed link between legend and historical fact, there may be a tendency to refer to narratives that correspond to one’s own beliefs as legends, while exactly comparable stories from other traditions may be classified as myths; hence a Christian might refer to stories about the miraculous deeds of a saint as legends, while similar stories about a pagan healer might be called myths. As in other cases, it must be remembered that the boundaries between terms for traditional narratives are fluid, and that different writers employ them in quite different ways. Parables
The term myth is not normally applied to narratives that have as their explicit purpose the illustration of a doctrine or standard of conduct. Instead, the term parable, or illustrative tale, is used. Familiar examples of such narratives are the parables of the New Testament. Parables have a considerable role also in Sufism (Islamic mysticism), rabbinic (Jewish biblical interpretive) literature, Hasidism (Jewish pietism), and Zen Buddhism. That parables are essentially non-mythological is clear because the point made by the parable is known or supposed to be known from another source. Parables have a more subservient function than myths. They may clarify something to an individual or a group but do not take on the revelatory character of myth. Etiologic tales
Etiologic tales are very close to myth, and some scholars regard them as a particular type of myth rather than as a separate category. In modern usage the term etiology is used to refer to the description or assignment of causes (Greek aitia). Accordingly, an etiologic tale explains the origin of a custom, state of affairs, or natural feature in the human or divine world. Many tales explain the origin of a particular rock or mountain. Others explain iconographic features, such as the Hindu narrative ascribing the blue neck of the god Shiva to a poison he drank in primordial times. The etiologic theme often seems to be added to a mythical narrative as an afterthought. In other words, the etiology is not the distinctive characteristic of myth. Approaches to the study of myth and mythology
The importance of studying myth to provide a key to a human society is a matter of historical record. In the middle of the 19th century, for instance, a newly appointed British governor of New Zealand, Sir George Grey, was confronted by the problem of how to come to terms with the Maori, who were hostile to the British. He learned their language, but that proved insufficient for an understanding of the way in which they reasoned and argued. In order to be able to conduct negotiations satisfactorily, he found it necessary to study the Maori’s mythology, to which they made frequent reference. Other government officials and Christian missionaries of the 19th and 20th centuries made similar efforts to understand the mythologies of nations or tribes so as to facilitate communication. Such studies were more than a means to an end, whether efficient administration or conversion. They amounted to the discovery that myths present a model or charter for human behaviour and that the world of myth provides guidance for crucial elements in human existence—war and peace, life and death, truth and falsehood, good and evil. In addition to such practically motivated attempts to understand myth, theorists and scholars from many disciplines have interested themselves in the study of the subject. A close study of myth has developed in the West, especially since the 18th century. Much of its material has come from the study of the Greek and Roman classics, from which it has also derived some of its methods of interpretation.
