In the light of the very fancy firearms portrayed in an earlier article today, this video clip of a secretary cabinet made for King Frederick William II of Prussia is a fitting way to end the day. It was made by Abraham and David Roentgen, master cabinetmakers of the 18th century. It's a remarkable combination of craftsmanship and artistry. I recommend watching this video clip in full-screen mode, if possible.
The cabinet is currently owned by a museum in Berlin. I shudder to think what its value must be today!
