Okay so looking up details of Lombard helmets gets me to the Broe helmet. Some of the other fragments in the grave include part of a “ring sword” - I’ve seen these but never known the name for the type. Okay BUT Wikipedia also gives Migration Period words for swords, including what might’ve entered Slavic languages as a loan word and is familiar to me as Russian Меч. Okay cool but also I hadn’t previously thought, the biologist L David Mech? That’s where the last name comes from.
