Literature is a human apocalypse, man's revelation to man, and criticism is not a body of adjudications, but the awareness of that revelation, the last judgement of mankind.
Northrop FryeCharacters tend to be either for or against the quest. If they assist it, they are idealized as simply gallant or pure; if they obstruct it, they are characterized as simply villainous or cowardly. Hence every typical character...tends to have his moral opposite confronting him, like black and white pieces in a chess game.
Northrop FryeMyths, as compared with folk tales, are usually in a special category of seriousness: they are believed to have "really happened,"or to have some exceptional significance in explaining certain features of life, such as ritual. Again, whereas folk tales simply interchange motifs and develop variants, myths show an odd tendency to stick together and build up bigger structures. We have creation myths, fall and flood myths, metamorphose and dying-god myths.
