Anglo Saxon Bling—A Warrior King’s Golden Helmet
In 2009 a metal detectorist discovered a vast hoard (4000 plus discrete and separate items) of Anglo Saxon gold and silver in a field in the U.K. Over the intervening years, most of the larger and recognizably important pieces have been identified and catalogued (https://www.staffordshirehoard.org. uk/staritems). Around 2500 fragments remained unidentified until two experts in Anglo Saxon iconography, over some months, jig-sawed many of these pieces together into what was declared to probably be the finest ever 7th century Anglo Saxon warrior king's helmet to be discovered. This paper describes in detail how two reproductions of the original helmet were made using multiple digital, technological and traditional jewelry and silversmithing techniques, some of which were developed specifically for the project. These techniques ranged from laser scanning, CAD and 3D printing to a new and novel method for stamping out highly detailed foil panels and repetitively decorated gallery strips almost three feet in length. Wire drawing tooling was also developed to enable the manufacture of many meters of “reeded” strips. Manufacturing the edging pieces required rediscovering the art of anticlastic raising. Finally, all of the parts had to be highly polished without losing the fine details and plated in gold or silver before being attached to a leather inner helm using riveting and glues made from bees wax and tree resins. The spectacular end result is now on display at the two museums in Birmingham and Stoke that share ownership of the original Staffordshire Hoard.
