Carsac - Saint-Caprais

The church, dedicated to Saint-Caprais (aka "Caprais d'Agen"), Bishop of Agen, martyred in the 4th century, is located at the confluence of the rivers Nea and Dordogne. The original design (nave and transepts) dates to the 12th century. During the 15th century two aisles were added to the (once) single nave church.

This capital is from the 12th century. It is very strange and enigmatic. Who is the roped person? Is he getting kicked and beaten? Martyred?
