A bronze metalworking die found in Denmark depicting a warrior on horseback suggests that the famous seventh-century helmet from Sutton Hoo in England may have been crafted in southern Scandinavia. The design on the stamp is remarkably similar to the horse-and-rider motifs on the ceremonial helmet, indicating a widespread motif throughout Northern Europe at that time.

The Sutton Hoo helmet, a mixture of Northern European and Roman styles, was rebuilt from fragments found at the burial site, which also contained ornate grave goods. While Anglo-Saxon smiths were capable of crafting such a helmet, the discovery of the stamp adds strength to the idea that it originated overseas, possibly as an heirloom or diplomatic gift.

Experts in England are excited about the new support for the idea that the iconic Anglo-Saxon helmet may have originated overseas. The similarity between the motifs on the stamp and the helmet suggests interconnected military elites in north-western Europe during that period, possibly indicating that the helmet was made in southern Scandinavia or heavily influenced by that artistic style.
