The sacrifice of Isaac (Gen. 22: 1-14) is among the most represented in religious sculpture. The theme reached its apogee in the romanesque period, specifically throughout the twelfth century. The Fathers viewed this as a prefiguration of Christ's sacrifice, especially when the sacrifice of Isaac is sculpted on capitals near the sanctuary, as at Conques. The carved text here is very similar to a 7th century inscription that accompanies a sculpted representation of the sacrifice of Isaac at San Pedro de la Nave: + Ubi Habraam obtulit Isaac filium suum olocaupstum Domino.
