The term mythology can refer either to the study of myths, or to a body or collection of myths. As examples, comparative mythology is the study of connections between myths from different cultures, where as Greek mythology is the body of myths from ancient Greece. In the field of folkloristics, a myth is defined as a sacred narrative explaining how the world and humankind came to be in their present form.Many scholars in other fields use the term "myth" in somewhat different ways.In a very broad sense, the word can refer to any story originating within traditions.
The main characters in myths are usually gods, supernatural heroes and humans.As sacred stories, myths are often endorsed by rulers and priests and closely linked to religion or spirituality.In the society in which it is told, a myth is usually regarded as a true account of the remote past. In fact, many societies have two categories of traditional narrative, "true stories" or myths, and "false stories" or fables. Creation myths generally take place in a primordial age, when the world had not yet achieved its current form, and explain how the world gained its current form and how customs, institutions and taboos were established.
Closely related to myth are legend and folktale. Myths, legends, and folktales are different types of traditional story. Unlike myths, folktales can be set in any time and any place, and they are not considered true or sacred by the societies that tell them. Like myths, legends are stories that are traditionally considered true, but are set in a more recent time, when the world was much as it is today. Legends generally feature humans as their main characters, whereas myths generally focus on superhuman characters.
The distinction between myth, legend, and folktale is meant simply as a useful tool for grouping traditional stories. In many cultures, it is hard to draw a sharp line between myths and legends. Instead of dividing their traditional stories into myths, legends, and folktales, some cultures divide them into two categories, one that roughly corresponds to folktales, and one that combines myths and legends. Even myths and folktales are not completely distinct. A story may be considered true (and therefore a myth) in one society, but considered fictional (and therefore a folktale) in another society. In fact, when a myth loses its status as part of a religious system, it often takes on traits more typical of folktales, with its formerly divine characters reinterpreted as human heroes, giants, or fairies.
Myth, legend, and folktale are only a few of the categories of traditional stories. Other categories include anecdotes and some kinds of jokes. Traditional stories, in turn, are only one category within folklore, which also includes items such as gestures, costumes, and music.
One theory claims that myths are distorted accounts of real historical events.According to this theory, storytellers repeatedly elaborated upon historical accounts until the figures in those accounts gained the status of gods. For example, one might argue that the myth of the wind-god Aeolus evolved from a historical account of a king who taught his people to use sails and interpret the winds. Herodotus (5th century BC) and Prodicus made claims of this kind. This theory is named "euhemerism" after the mythologist Euhemerus (c.320 BC), who suggested that the Greek gods developed from legends about human beings.
Some theories propose that myths began as allegories. According to one theory, myths began as allegories for natural phenomena: Apollo represents fire, Poseidon represents water, and so on. According to another theory, myths began as allegories for philosophical or spiritual concepts: Athena represents wise judgment, Aphrodite represents desire, etc. The 19th century Sanskritist Max Müller supported an allegorical theory of myth. He believed that myths began as allegorical descriptions of nature, but gradually came to be interpreted literally: for example, a poetic description of the sea as "raging" was eventually taken literally, and the sea was then thought of as a raging god.
Some thinkers believe that myths resulted from the personification of inanimate objects and forces. According to these thinkers, the ancients worshipped natural phenomena such as fire and air, gradually coming to describe them as gods.For example, according to the theory of mythopoeic thought, the ancients tended to view things as persons, not as mere objects; thus, they described natural events as acts of personal gods, thus giving rise to myths.
According to the myth-ritual theory, the existence of myth is tied to ritual. In its most extreme form, this theory claims that myths arose to explain rituals. This claim was first put forward by the biblical scholar William Robertson Smith. According to Smith, people begin performing rituals for some reason that is not related to myth; later, after they have forgotten the original reason for a ritual, they try to account for the ritual by inventing a myth and claiming that the ritual commemorates the events described in that myth. The anthropologist James Frazer had a similar theory. Frazer believed that primitive man starts out with a belief in magical laws; later, when man begins to lose faith in magic, he invents myths about gods and claims that his formerly magical rituals are religious rituals intended to appease the gods.
Functions of myth
Mircea Eliade argued that one of the foremost functions of myth is to establish models for behavior and that myths may also provide a religious experience. By telling or reenacting myths, members of traditional societies detach themselves from the present and return to the mythical age, thereby bringing themselves closer to the divine.
Lauri Honko asserts that, in some cases, a society will reenact a myth in an attempt to reproduce the conditions of the mythical age. For example, it will reenact the healing performed by a god at the beginning of time in order to heal someone in the present. Similarly, Roland Barthes argues that modern culture explores religious experience. Because it is not the job of science to define human morality, a religious experience is an attempt to connect with a perceived moral past, which is in contrast with the technological present.
Joseph Campbell defined myths as having four basic functions: the Mystical Function—experiencing the awe of the universe; the Cosmological Function—explaining the shape of the universe; the Sociological Function—supporting and validating a certain social order; and the Pedagogical Function—how to live a human lifetime under any circumstances.
