 This is either an undocumented first wife of Giovanni di Arrigo or a second wife of Giovanni di Nicolao, or, according to a recent proposal, Giovanni di Nicolao's first wife Costanza Trenta, who had died perhaps in childbirth by February 1433.In the latter case, this would make the painting partly an unusual memorial portrait, showing one living and one dead person.Details such as the snuffed candle above the woman, the scenes after Christ's death on her side of the background roundel, and the black garb of the man, support this view.
