The nave’s ten capitals are among the most unusual of Anjou’s Romanesque works. They are divided into three groups :
the first is exclusively of plants,
the second shows fantastic monsters
and the third is made of two historiated capitals. These last face the North doorway, the lay people’s doorway, and so a favoured position. They symbolize the two powers around which the medieval world was organised : the clergy and the nobility. On the first capital, one of the angles shows a priest with raised hands, officiating and accompanied by two assistants carrying sacred vessels. The other angle is occupied by an ecclesiastical figure carrying a tau-shaped, pastoral baton. On the second capital, a crowned knight, accompanied by a falconer, strikes down a dragon, representing evil.
