The recognition that the majority of glass was made from sand and soda in the eastern Mediterranean, then shipped as unworked chunks to be shaped in glass workshops across the known world, has led to renewed interest in glass as an item of trade, and the ebb and flow of its manufacture and movement. The present volume grew out of a symposium held to address issues around the movement of glass. In November 2014, 125 delegates from across the world attended a two- day conference held in the British Museum, the Wallace Collection and UCL’s Institute of Archaeology. It was organised by UCL’s Early Glass Technology Research Network (EGTRN), the Association for the History of Glass (AHG) and the British Museum. The success of the meeting and the high level of dis- cussion prompted us to explore the possibility of a volume on the topic and number of participants agreed to prepare chapters related to their contributions. The title, Things that Travelled: Mediterranean Glass in the First Millennium CE, references a 2004 article by the late David Whitehouse (‘ “Things That Travelled”: The Surprising Case of Raw Glass’, Early Medieval Europe 12 (3), 301– 5). Whitehouse’s article was intended to be ‘an interim report on work in progress on glass’ and was inspired by Michael McCormick’s Origins of the European Economy: Communications and Commerce, AD 300–900 (Cambridge University Press, 2001) who had expressed the hope that, in the near future, archaeologists would contribute fresh information on the movement of ceramics and glass. Ten years later, it seemed to be a fitting time for archaeologists and scientists to give an update on their progress. v vi The volume aims to contribute to our understanding of glass pro- duction, distribution, trade and technologies and to contextualise this material within the social, economic and cultural framework of ancient societies. Chapters encompass various glass artefact groups (jewellery, vessels, secondary and primary production remains) from a plethora of regions such as Greece (Antonaras), Bulgaria (Cholakova and Rehren), Cyprus (Cosyns and Ceglia), the Libyan Sahara (Duckworth and Mattingly), Egypt (Rosenow and Rehren), Italy (Maltoni et al., Silvestri et al.), Jordan (O’Hea), Israel (Phelps), Britain (Sainsbury, Davis and Freestone), covering the Roman, Late Antique and early Islamic periods. Aspects discussed include the place of origin and production of raw glass, technology, patterns of distribution and trade, raw glass ingredients, the usage and spread of specific object groups such as gold- glass (Cesarin, Walker et al.), gems (Antonaras) or objects made of emerald green glass (Cottam and Jackson), as well as the relationship between objects made of glass and other materials. Analytical chapters focus on the chemical definition, introduction and distribution of various raw glass groups such as HIMT glass (Freestone et al.), aspects such as glass recycling (Sainsbury), the supply and trade of natron and plant ash glass in Upper Egypt (Rosenow and Rehren), and the characterisation of new plant ash glass groups in early Islamic Palestine (Phelps). We would like to thank all authors of the chapters included here as well as the other contributors to the conference for presenting their research. Further thanks are due to the British Museum, the Wallace Collection, and UCL’s Institute of Archaeology for providing conference space; to UCL and the Association for the History of Glass for providing funding (grants for travel and accommodation for participants, print per- missions for images); and to UCL Press. Finally, we would like to thank all those students of UCL who helped in the organisation of the conference, in particular Laura Adlington, Ana Franjić, Umberto Veronesi, Carlotta Farci, Nyree Manoukian, Martina Bertini and Jo Ahmet.
