Saint Gregory the Great, possibly

These figures are from the Abbey of SS. Nazaro e Celso in Verona. In the fourteenth century, this abbey was run by the Knights Hospitaller. They probably represent two of the four Fathers of the Church - Saints Ambrose and Gregory. There would originally have been two other figures. It is not certain how they were originally intended to be displayed. Although they may have been intended for a church facade, the figures are unweathered, suggesting that they have spent most of their lives indoors.
