Ghent Altarpiece
The Ghent Altarpiece, also called the Adoration of the Mystic Lamb (Dutch: De aanbidding van het Lam Gods), is a very large and complex 15th-century polyptych altarpiece in St Bavo's Cathedral, Ghent, Belgium. It was begun around the mid-1420s and completed by 1432, and it is attributed to the Early Netherlandish painters and brothers Hubert and Jan van Eyck. The altarpiece  is a prominent example of the transition from Middle Age to Renaissance art and is considered a masterpiece of European art, identified by some as "the first major oil painting." 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 represents the heavenly redemption, and includes the central classical Deësis arrangement of God (identified either as Christ the King or God the Father), flanked by the Virgin Mary and John the Baptist.
