This database of magical gems, named after Campbell-Bonner’s famous collection of 1954, is in fact far more extensive, containing over 1,000 items. These are drawn from over 30 collections, including the British Museum, and the Budapest Museum of Fine Arts, which is curating the website with the University of Fribourg, under the direction of an international editorial board. According to the site, the database, which is currently expanding, contains “a fourth of the known corpus of magical gems.” Its search functions allow the user to browse the gems by collection, material, place of discovery (only a few of which are known), iconographical schemes and elements, vocabulary (gem inscriptions in Greek and Latin), names, voces magicae, Logoi, and Characteres. The entries themselves contain this information, when available, along with digital images of the gems; these can even be sent as electronic postcards! There is a small glossary and bibliography, which has the helpful feature of noting the gems referred to in each entry. Clearly this is a major resource, which will become even more important as the site grows.
