Early medieval window glass from Müstair

More than 2000 coloured glass fragments unearthed in the excavations at the UNESCO World Heritage Site of St John’s monastery in Müstair (the Grisons) have been studied in this interdisciplinary project. Archaeological, technological and art historical research aimed at casting light on the provenance of the glass and the fabrication of flat glass in the early Middle Ages, as well as the design of the ornamental windows in the Carolingian monastery. The study was part of a larger project, which also encompasses the early medieval window glass found at the funeral church at Soux-le-Scex, Sion.
