A medieval ship flag captured by forces from Lübeck in the 1420s showed the arms of Denmark, Sweden, Norway and Pomerania. It remained in this city for 500 years, until destroyed in a World War II bombardment that damaged St. Mary's Church where the flag was kept. A 19th century copy remains in Frederiksborg Palace, Denmark. The saint accompanying the Virgin Mary and infant Christ is Saint James the Greater, identified by his scallop shell emblem. The flag was made of coarse linen; all figures and heraldic insignia were created using oil-based paint.
