The literature of the Middle Ages is an expression of the spirit of feudalism and of the genius of the Church. From the union of feudalism and Christianity arose the chivalric ideals, the new courtesy, the homage to woman. Abstract ideas, ethical, theological, and those of amorous metaphysics, were rendered through allegory into art. Against these high conceptions, and the overstrained sentiment connected with them, the positive intellect and the mocking temper of France reacted; a literature of satire arose.
