Although it is probable that the traditions formed around these objects, which were equally familiar at Rome and at Constantinople, never entirely died out, still little evidence exists of the use of medals in the Middle Ages. No traces of such objects that survive are remarkable either for artistic skill or for the value of the metal. In the life of St. Genevieve, it is recounted that St. Germanus of Auxerre, having stopped at Nanterre while on his way to Britain, hung around her neck a perforated bronze coin marked with the sign of the cross, to remind her of having consecrated her virginity to God. The language seems to suggest that an ordinary coin was bored for the purpose. Many of the coins of the late empire were stamped with the chrisma or with the figure of the Saviour, and the ordinary currency may often have been used for similar pious purposes.
