Ghent Altarpiece Ghent Altarpiece The Ghent Altarpiece (or the Adoration of the Mystic Lamb, ) is a very large and complex 15th-century polyptych altarpiece in St Bavo's Cathedral, Ghent, Belgium. It is attributed to the brothers Hubert and Jan van Eyck, who were Early Flemish painters. It is considered a masterpiece of European art and one of the world's treasures. The panels are organised in two vertical registers, each with double sets of foldable wings containing inner and outer panel paintings. The upper register of the inner panels form the central Deësis of Christ the King, Virgin Mary and John the Baptist.
Ildefonso Altarpiece was commissioned for the Brotherhood by his widow shortly after his death. Ildefonso Altarpiece 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
