Uccello is best known for his battle scenes for the Medici palace and for frescoes in the cloister of Santa Maria Novella, Florence; however, he also painted small devotional panels. This portable triptych includes the depiction of a nun of the Brigitine order at the foot of the cross, identified by an inscription as Sister Felicity. It was for her private devotions in her cell at the Brigitine convent of Santa Maria del Paradiso near Florence that the triptych was painted. A Felicità di Francesco Casavecchia joined the order in January 1455, which is about the date of the painting.
