The Tjele helmet fragment is a Viking Age fragment of iron and bronze, originally comprising the eyebrows and noseguard of a helmet. It was discovered in 1850 with a large assortment of smith's tools in Denmark, and though the find was sent to the National Museum of Denmark, for 134 years the fragment was mistaken for a saddle mount. In 1984 it was properly identified by an assistant keeper at the museum as the remainder of one of only five known helmets from the Viking era. Dating to approximately 950 to 970 AD, the Tjele fragment is joined by the Gjermundbu helmet, two fragments from Gotland, and one from Kiev, as the known Viking Age helmets. These represent the final evolution of the "crested helmets" used in Europe from the sixth century onwards, and known primarily for Anglo-Saxon and Vendel Period examples such as the Sutton Hoo helmet. The Tjele fragment is one of only two such helmets discovered in Denmark; the earlier Gevninge helmet fragment, made in approximately 550 to 700 AD, was discovered in 2000. Description A "wing-shaped object", the fragment measures approximately wide and tall. It was made in one piece, and has "evidence of possible extensions towards the base of the nasal". Though now the fragment comprises only the eyebrows and nasal of a helmet, it likely once formed part of a face mask like that on the Gjermundbu helmet, which had "curved linking strips" circling under the wearer’s eyes. The method employed to construct the remainder of the helmet is unknown. "There is not a trace of chain mail in the find, nor any iron plates fit for making up the rest of the helmet." Eight fragments of "thin iron strips, about broad and of varying length" were found, however, and may have been originally used to join the helmet plates. Discovery The Tjele fragment was discovered amidst a tenth century collection of smith's tools in 1850, but its significance was not understood until 1984. Originally discovered by a farmer planting saplings by Tjele Manor, between Viborg and Randers, it was sent by the manor's owner to the National Museum of Denmark, where it remains today. In 1858 the collection of tools—two anvils, five hammers, three pairs of tongs, a pair of plate shears, two files, a chisel, two drawplates, two foundry ladles, a whetstone, a set of balance scales with ten weights, five sickles,
