International audience Two crossbow fibulae, belonging to the clothing tradition of the Eastern Germans, were unearthedin a tomb (n° 94) in the necropolis of Saint-Chéron, in Chartres (France). These fibulaeare derived from those of the Ambroz 16/4-III type, belonging to the late Roman period andcharacteristic of the Chernyakhov culture (in the southern part of Eastern Europe), i.e. Germanicand non-Germanic population (the Goths and their allies). These fibulae are attested,yet more scarcely, on the sites of the cultures of Wielbark and Przeworsk in the Vistula basin,belonging to the Eastern Germans. These fibulae from Eastern and Central Europe are datedfrom the 3rd and the 4th centuries. Concerning the time of the Great Migrations, mainly forthe 5th century, crossbow fibulae derived from those of Ambroz 16/4-III are rare and attestedoutside of the main area of distribution of their prototypes: in the North-East of the BlackSea (1 site), in Spain (1 site), in Italy (1 site) and especially in Gaul (3 sites). Fibulae of theAmbroz 16/4-III type and their derivatives were found mainly in the area of activity of theGoths during the Roman Period and the Great Migrations, between the Vistula, the Black Seaand the Iberian Peninsula. The few fibulae of this type discovered elsewhere, in Northern Gaulfor example, probably attest to the displacement of isolated individuals. Indeed, in the tomb ofSaint-Chéron, the position of the pair of fibulae, on the thorax, is entirely in accordance withthat adopted by the Eastern Germans in Roman times.
