409 abstract This paper discusses technological and stylistic variations in copper-alloy workshops in Viking Age towns. In the decades around year 800 a cluster of new technologies, art styles and object types, including the characteristic oval brooches, were adopted across Scandinavia. Shared details of technology indicate close communication between workshops in Ribe and Birka, yet craftspeople cultivated styles which were specific to the particular town. However, the distribution of the products is not confined to specific regions. The persistence of the stylistic choices is suggested to be a marker of professional identity among craftspeople. This could indicate that the first urban craftspeople in Scandinavia were communities with a sense of civic identity, rather than itinerant cosmopolitans. Crafted products, along with the refuse from workshops, are among the rich- est and most informative categories of archaeological evidence pertaining to the urban sites of the Viking period. They allow rare insights into the cultural knowledge and communication of people in Scandinavia’s first towns. Debate surrounds the character of these places: Were Viking Age town-dwellers a supra-regional society of itinerant cosmopolitans, or relatively settled commu- nities with a sense of civic identity? The technological and stylistic similarities of products crafted in urban workshops across the Viking world have gained ground for the former view. This paper draws attention to some observations, which move the balance towards the latter. In the early Viking period a cluster of new technologies for copper- alloy working were adopted in urban workshops in Scandinavia. The recep- tion of these innovations, and the styles they inspired, created a new range of ornaments, including the characteristic oval brooches of the traditional Scandinavian female dress. Finds from urban workshops indicate that despite close communication and shared technology, craftspeople cultivated styles which were specific to particular towns. The persistence of these choices in individual sites contrasts with the randomness that characterises the regional Urban Crafts and Oval Brooches Style, Innovation and Social Networks in Viking Age Towns SøRen M.
