Ducal hat

The Duke's hat did not take on its present compact shape until 1766. The prongs made of profiled metal strips with a stamped diamond pattern and quatrefoil motif as well as the bow with crabs date from the time of Duke Ernst the Iron (1377-1424), father of the later Emperor Frederick III. Instead of the high ermine brim, only the triangles of the prongs were probably originally lined with fur.
