Its panel of the Just Judges was stolen in 1934, and, on the outside, the donors Jodocus Vijd and Lysbette Borluut appear along with grisaille depictions of Sts. John the Baptist and John the Evangelist. Between them and the prophets and sibyls in the top register is an Annunciation in which the shadow of the frame is visible. Also in grisaille are the Sacrifice and Murder of Abel on the interior atop nude depictions of Adam and Eve, which frame two angelic choirs and a deesis group. In its bottom register, hermits, pilgrims, martyrs, and prophets approach the Fountain of the Water of Life and the Lamb of God. FTP, name this polyptych by two Netherlandish brothers, Hubert and Jan van Eyck.
