"The Four Apostles"
The Bavarian Elector Maximilian I obtained The Four Apostles in the year 1627 due to pressure on the Nuremberg city fathers. Since then, the painting has been in Munich and, despite all the efforts of Nuremberg since 1806, it has not been returned.
When Dürer moved back to Nuremberg he produced many famous paintings there, including several self-portraits. He gave The Four Apostles to the town council. Saints John and Peter appear in the left panel; the figures in the right panel are Saints Mark and Paul. Mark and Paul both hold Bibles, and John and Peter are shown reading from the opening page of John's own Gospel. At the bottom of each panel, quotations from the Bible are inscribed.
The apostles are recognizable by their symbols:
St. John the Evangelist: open book
St. Peter: keys
St. Mark: scroll
St. Paul: sword and closed book
