Its plan remains square during first half of the 13th century, but then it is more decorated only by profiles of a cut very-male (3), always overflowing the foliages and ornaments of the capital.

One often meets circular abacuses in the buildings of the province of Normandy, with the cathedral of Coutances, in Bayeux, in Have, the Mount-Saint-Michel; the circular abacuses appear about the middle of the 13th century: the profiles high, are deeply overhanging it, like those of the English capitals of the same time.
