Peter Francis Jr. has devoted much of his research to Indo-Pacific glass beads. These productions are among the emblematic objects made by South Asian glass workshops for nearly two millennia. Despite their wide distribution, both in Asia and Africa and in the Middle East, these tiny beads have never been reported in Western Europe. They have recently been found in large numbers on funerary sites in Merovingian Gaul, dated to between the middle of the 5th and the middle of the 6th century AD (mainly in the form of necklaces or clothing ornaments). Their presence stimulates reflection on the extensive trade between the Merovingian and the Indian worlds. This contribution discusses the technological, typological and chemical characteristics of these beads, as well as their use.
