Saint Diego of Alcalá

Saint Diego of Alcalá — a 15th-century Franciscan lay brother canonized in 1588 — was a popular devotional figure in Counter-Reformation Spain, particularly associated with miraculous healings. Zurbarán painted him for Franciscan communities who celebrated the saint's miraculous transformation of hidden food into roses. The 1640 date places this among Zurbarán's mature works, when his mastery of devotional figure painting was at its height.

Diego is shown in Franciscan habit, typically with roses or bread miraculously revealed in the folds of his habit. Zurbarán renders the rough Franciscan brown wool with the same sculptural precision he brings to any textile, and the figure's humble, joyful bearing is characteristic of his treatment of this gentle saint.
