Ghent Altarpiece(detail), Van Eyck Brothers Tissue Paper

The Ghent Altarpiece (or the Adoration of the Mystic Lamb, Dutch: Het Lam Gods) is a large and complex 15th-century polyptych altarpiece in St Bavo's Cathedral, Ghent, Belgium. It was begun c. the mid-1420s and completed before 1432, and is attributed to the Early Flemish painters and brothers Hubert and Jan van Eyck. The altarpiece 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 represent the heavenly redemption, and include the central Deësis of Christ the King (or perhaps God the Father), the Virgin Mary and John the Baptist. They are flanked in the next panels by angels playing music and, on the far outermost panels, the figures of Adam and Eve. The four lower-register panels are divided into two pairs; sculptural grisaille paintings of St John the Baptist and St John the Evangelist, and on the two outer panels, donor portraits of Joost Vijdt and his wife Lysbette Borluut. The central panel of the lower register shows a gathering of saints, sinners, clergy and soldiers attendant at an adoration of the Lamb of God. There are several groupings of figures, overseen by the dove of the Holy Spirit.[A] The altarpiece is one of the most renowned and important artworks in European history. Quote:Wikipedia
