Recto: St Mary Cleophas and Alphaeus (with the features of Friedrich the Wise) and his two sons are depicted on the front of the panel. The interior shown on the central panel opens out onto a terrace on the left wing. At the back a wall with pillars and a section of a defensive wall separate the terrace from the landscape beyond. St Mary Cleophas sits on the ground with her head bowed and nurses a child (James the Less). Her legs are stretched out to the right, whereas her upper body is shown from the front. She wears a black robe under her red coat and a black bonnet with a gold border on her head. Alphaeus stands behind her in contemporary dress. He wears a white shirt and green leggings under a gold brocade coat and a beret on his head. A small boy (Barnabas) sits on his honkers in the foreground and leafs through a book. Verso: The Virgin and Child are depicted in grisaille on the reverse of the panel. They are shown frontally in an arched niche. She holds the naked Christ Child in both hands symmetrically in front of her chest. He sits on the palms of her hands and is turned in profile to the right with his arms around the Virgin's neck. She wears a coat with wide sleeves, which falls in broad tubular folds and billows out on the ground at the left. The folds of the skirt of her robe are only visible at the bottom right. Both have a halo in the form of a disk, which emphasizes the impression that they are sculptural elements. [see Cat. Frankfurt 2005, 204-225]
