Crypts are rare in Saxon churches and suggests an Italian or a Carolingian influence . There is also strong evidence of the Carolingian influence , particularly in the crypt . Viking art , the Carolingian and Ottonian renaissances , Romanesque architecture and the convergence of Christian and Islamic influences in Spain , Sicily and the Crusader states . Capetian and Carolingian dynasties in France , during a period when the Capetian dynasty was using the Church to help establish their claim to the throne at the expense of the last Carolingian claimant . The development that the vestment has undergone from the Carolingian period up to the present time has been in all points similar to that of the dalmatic ; during the course of this development the distinction between the dalmatic and the tunic steadily decreased .
