School of Ulm, circa 1510

Two wings by the same hand, traditionally given to Bartholomaeus Zeitblom, are in the Fogg Art Museum, Harvard University, and the Biberach Museum, near Ulm. The panel depicts Bishop Severus of Ravenna, with his attribute of a white dove, and the Apostle Simon Zelotes with his wooden club. As Ludwig Meyer notes (private correspondence, March 2005), it is likely that the complete altarpiece would only have had two wings enclosing a shrine with sculpture, and that the other wing would have possibly portrayed another holy bishop and the Apostle Judas Thaddeus, who was the brother of Simon Zelotes.
