Quite intricately made with angled notched bit and square section shank with tapered flare to stop the key in position. Pierced circular terminal to allow suspension, probably with others as each lock and key were unique. Just over 4” length and particularly well forged. Slaving was a primary occupation for Vikings. European slaves were kept in Viking communities and sold to the North African trade. Coastal Italian towns were particularly vulnerable as they could be raided and the captives immediately transported across the Mediterranean to the North African markets.
