[7] háseymða hjálma ‘rivet-studded helmets’: Háseymðr, p. p., means lit. ‘nailed high up’ (LP: hôseymðr). What seem to be in question here are helmets of the type illustrated by Thordeman (1941, 93), of which fragments dating from the C5th and C6th have been found at Tuna on Gotland. This type of helmet, not commonly found in Scandinavia, appears to have consisted of a circlet from which four or six metal strips shaped like upturned Ts curve upwards and inwards, forming a conical shape, and meet at a rounded top where they are held together by a boss, the spaces between the strips being filled by convex metal plates attached from below to the strips by rivets, the heads of which appear on the exterior of the helmet.
