The decoration of the voluminous capitals of the narthex, masterpieces of composition, uses plant or animal motifs, such as these wolves and she-wolfs whose heads come together, at the corner, to remove a sheep, a bird or a cub in their mouth. These animals with outstretched bodies, arranged in an X on the main face, announce those of the trumeau; these plant and animal images can evoke the Garden of Eden.
