This type of hammer pendant was the symbol of the god Thor, the Nordic god of thunder and lightning. Similar examples have been found chiefly in south and central Scandinavia, but some have been found as far away as Iceland, England and Poland. They are usually cast, like the present example, but some are cut from sheet metal and embellished with filigree and granulation. For a description of the type and for another of similar form see p. 190 in A.-S. Gräslund, "Thor's hammer, pendant crosses and other amulets," in E. Roesdahl and D.M. Wilson, eds., From Viking to Crusader, The Scandinavians and Europe 800-1200.
