Juan de Borgona illustrates Saint Gregory wearing a cope (cloak) over a white rochet (linen or muslin tunic) and the triple crown of a Pope. He was one of the four theologians known as the ‘Doctors of the Church’ together with Saints Augustine, Ambrose and Jerome. Saint Augustine is depicted writing, which is a reference to the many books that he produced. These books are still used by theologians today. De Borgona is thought to have been born in Burgundy, France. He is later believed to have visited Italy and worked in the studio of Domenico Ghirlandaio. He entered the service of the archbishop of Toledo in 1495, decorating churches in Gerona and Toledo, and becoming a wealthy man as a result.
