Large-sized glass beads of undetermined use have been repeatedly found in graves of Northern Gaul, mostly dated from the first quarter of the 6th century (MA1). These distinctively shaped beads (Legoux 50 or 51) are usually found near the lower members in women’s graves. Archaeologists often identify them as belt pendants. There also remains the old hypothesis of their being luxury spindle-whorls, lucky charms or swordbeads in the case of rare occurrences in men’s graves. All three hypotheses are discussed and validated in this study. An experimental archaeology protocol, augmented by the study of production traces, shows that the use of these large-sized beads as spindle whorls is highly likely. The hypothesis according to which these beads were strung does not contradict that of a spindle suspended from the belt since other suspended objects are found, such as knives, keys or shearing scissors.
