The first volume of Lévi-Strauss' series Mythologiques, this long book in very small print (not enlargeable in the format Open Library uses) is a classic of twentieth-century anthropology (also available in English translation as The Raw and the Cooked.) He begins by analyzing a myth of the Bororo people (one of the central Brazilian tribes which were the subject of his own fieldwork, described in Les tristes tropiques) about the origins of destructive weather (heavy wind and rains). He then moves to a group of similar myths of neighboring tribes which speak languages of the Gé family, dealing with the origins of (domestic cooking) fire, which have elements in common with the Bororo myth. Throughout the book, he picks up new elements in certain myths and then seeks other myths which contain those elements, ending up discussing groups of myths about (inter alia) the origins of cultivated plants, fishing and hunting with poisons, death and diseases, and the differentiation of various species of animals and birds. In so doing, he also brings in many different regions of Brazil and the Amazon basin, and occasionally analogues from elsewhere in South and North America.
Lévi-Strauss' basic theory of structuralism is that myths (and other cultural traits), like language, are built up from underlying (and pre-conscious) structures of oppositions analogous to phonemes, which are expressed in various "codings" analogous to grammar, then modified by sytematic transformations to provide specific messages (content). Important oppositions include Nature/Culture (which can be coded as the raw and the cooked), Heaven/Earth/Water, Male/Female, Life/Death, Animal/Human/Plant, and so forth. Some categories "mediate" others; thus the cooked mediates between the raw and the spoiled (pourri). He explains the functions of particular birds and animals through the various myths in terms of the oppositions they represent (many myths are about opposums, vultures, jaguars, turtles and armadillos, for example.) His theory is much too complex to summarize in a short review.
Whatever one thinks of structuralism as a theory, this book would be worth reading just for the myths alone.
