Named others on the file: Jakob Heller as patron, unnamed assistants on wings, and later copyists share the file. The public setting is the file around 1509-01-01. Unnamed clerks, soldiers, printers, or later editors may appear without becoming this instrument. The instrument stays Dürer delivers the Heller Altar central panel for a Frankfurt patron.
