Restoration of the Triptych of the Redemption (c. 1450) by the Master of the Prado Redemption, with commentary by Herlinda Cabrero Cabrera, conservator at the Museo Nacional del Prado.

The triptych once belonged to Leonor de Mascarenhas (1503–1584), a Portuguese noblewoman who arrived in Spain in 1526 and served first as governess to Philip II and later to his son, Prince Don Carlos. In 1564, when she founded a convent of Franciscan nuns in Madrid under the dedication of Our Lady of the Angels, she donated several paintings to the institution, among them the triptych discussed here. Nothing is known about its earlier history.
