GLOBALGLASS is a Marie Skłodowska-Curie project based at the Newcastle University (2015-2017). It focuses on the cross-cultural consumption of glass bangles, i.e. rigid, ring-shaped objects composed of coloured glass, used by the inhabitants of the European northwest borderland regions during the transition from the Late Iron Age to Roman period, c. 100 B.C. – A.D. 250. This project introduces the pan-European ‘glass adornments event horizon’, which signals the existence of an active multicultural community with its own forms of decorative identification in the borderland regions. It assesses the evidence for this phenomenon in four north-western European countries (Germany, the Netherlands, Belgium, and United Kingdom) and explores its regional ramifications, by concentrating on one area, United Kingdom, in order to understand the manifestation of this inter-cultural event in a local setting. At the center of attention are the transformative role these annulars played in the formation of inter-European and regional identities in a transitional period when new cultural forms and practices emerged in the European Northwest.
