This volume contains thirteen papers from a conference held in the Römisch-Germanisches Zentralmuseum in Mainz in 2015. The contributions primarily deal with the material culture of goldsmiths’ works, such as crosses, reliquary caskets, jewellery, enamel works, and precious stones, spanning the wide geographical area of Byzantium and many of its neighbours, from Russia via Trebizond and Serbia to Crete. Furthermore, written sources on Byzantine goldsmiths, their craft and the provenance of precious metals provide evidence for goldsmithing in Byzantium throughout its history.
