The figures in the four panels of the lower register are all positioned within uniform niches. The outer panels show the donors Joost Vijdt and his wife Lysbette Borluut. The inner panels contain grisaille paintings of Saint John the Baptist and Saint John the Evangelist. The grisaille is used to give the illusion of sculpture and imply that these are cult representations of the two saints before which the donors kneel, gazing into the distance with their hands clasped together in veneration. As with the most of the other panels on the inner and outer views, they are lit from the right. Shadows thrown by the figures establish depth, and bring realism to both the faux statues and painted niches.
