This triptych consists of five panels, the central one depicting a bust of Christ with a halo incorporating a cross. He presides over the composition, flanked on the inside of the lateral panels by Saint Peter with his keys and Saint John the Baptist wearing his hair shirt. On the exterior of the lateral panels are Saint John the Evangelist holding a pen and his Gospel, and Saint Columba (9th century), accompanied by the bear that miraculously saved this Spanish nun from rape. All the saints have banners with inscriptions praising Christ. This altarpiece is typical of Romano’s traditional approach in which the figures are treated as icons, set against gold backgrounds and isolated from any narrative context.
