The triptych of Saint Ildefonso
Peter Paul Rubens
The Ildefonso Altarpiece is a triptych painting by Peter Paul Rubens, dating to between 1630 and 1631. It is now in the Kunsthistorisches Museum of Vienna.
It is named after the central panel, which shows Saint Ildefonsus's vision of the Virgin Mary, in which she gave him a casula. On the side panels are Isabella Clara Eugenia and Albert VII, regents of the Spanish Netherlands, with their patron saints Albert and Elisabeth of Hungary. Albert had founded the Ildefonso Brotherhood in the church of Saint Jacques-sur-Coudenberg in Brussels, to encourage loyalty to the Habsburg dynasty - the altarpiece was commissioned for the Brotherhood by his widow shortly after his death.
