The concept of the mythical charter, validating claims to ritual or political authority, is a familiar one to social anthropologists, although, due to a better understanding of the interaction of myth and history, there has been a tendency in recent years to speak of the ‘historical’ rather than the ‘mythical’ charter. Those who use such terms are not primarily interested in the charter as evidence of a system of ideas, worth studying for its own sake. Their emphasis is on the function of the charter, rather than on its meaning. However, a brilliant lead has been given in the exploration of myths as systems of ideas by Claude Lévi-Strauss who places a given text within the whole corpus of oral literature proper to a society. Going, perhaps, further than this, Victor Turner corrects the predominantly literary approach of Lévi-Strauss by his examination of the ‘positional meaning’ of the symbols employed by such texts—a meaning derived from a totality of elements, rites, and institutions within a whole culture.
