The eyebrow has been roughly dated to the beginning of the
Vendel Period, during the second half of the sixth century. Based on this period, and location, it fits into the corpus of "crested helmets", each characterized by a rounded cap and usually a prominent nose-to-nape crest, that appeared around this time in
England and
Scandinavia. More than half of the known examples are from Sweden; up to twenty are from Gotland alone, although these were typically found in cremation burials and, like the Hellvi example, comprise only a fragment or two. The Hellvi example is one of many crested helmets to have featured decorated eyebrows. The
Broe helmet—also from Gotland—and the
Sutton Hoo helmet both have eyebrows with animal-head terminals, and inlaid strips of metal. The decorative motif of incised vertical strips has been repeated on other helmets, such as from
Vendel and
York, in what is probably a cheaper imitation, or an invocation of an earlier style. Other decorated helmet eyebrows have also been discovered alone. These include
another decorated eyebrow from Gotland, in
Lokrume, an eyebrow from
Uppåkra on the mainland, and an
ornate helmet eyepiece from
Gevninge, Denmark. The singularity of at least the latter two finds has led to an association with the
Germanic god
Odin, who reputedly gave one of his eyes to drink from the well of wisdom. Another artefact found in Hellvi—a Roman mask that saw continued use in the
Iron Age, and was found in a house dating to around 550—had one eye removed and buried nearby, further suggesting the contemporaneous significance of singular eyes. == See also ==
