A copper alloy fibula discovered in August 2017 by a treasure hunter in the immediate vicinity of Hesdin (Pas-de-Calais) can be attributed to the Jansson II.D class of the Borre style circular fibulae. This group can be dated from the 1st half of the 10th century; it is found mostly in the Scandinavian area (Denmark, Sweden, Faroe Islands, Danelaw). Since the archaeological context is missing, it is not possible yet to determine by what route it came (through the Danelaw or the Friesians?) and for what purpose (trade, transit, heterogamic wedding present…).
