This architectural drawing, "Altarentwurf," by Johann Baptist Straub, is a design for an elaborate altar. The design is characterized by symmetrical, classical elements such as columns, pilasters, and an ornate pediment. The drawing includes two figures, likely St. John the Baptist, on either side of the central space reserved for the altar piece. This drawing, currently held by the Städel Museum, provides a glimpse into Straub's approach to altar design and his skill in rendering architectural details. The composition reflects a typical Baroque architectural style with its emphasis on grandeur and ornamentation.
