Restored to St. Bavo Cathedral. 12 panels comprise the polyptych. The altarpiece has two tiers, each with four hinged wings. When closed for weekday Masses and in Lent , it represents the moment of the Incarnation, depicted as an Annunciation. On the lower tier Vijd and his wife (donors) are shown with SS. John the Baptist and the Evangelist, painted in grisaille. When the upper tier was open on ordinary Sundays, it showed Christ, the Virgin and St John the Baptist. When the retable was fully opened for a major feast, these figures presided over a paradisical scene below of the Adoration of the Lamb.
