The image of the angel on coins replaces that of the Victory starting from the solidi of Justin I in 522. Its assimilation to the Eternal Victory of Rome gave it the wings that would become its characteristic feature. It also completed the slow Christianisation of this element derived from Hellenistic and Imperial coinage. In the 5th century numerous Christian attributes (labarum, globus cruciger, cross) were added and later disappeared completely at the beginning of the 6th century. From the 11th century onwards, the predominant image is that of the Archangel Michael, the patron saint of the military aristocracy. The archangel remains associated with the ideal of power and illustrates the protection granted to the emperor by the Pantocrator of whom he is, after the angels, another winged envoy. The late numismatics of the Thessaloniki workshop made the wings, attached to an effigy of the sovereign or alone, an imperial attribute, symbol of power and legitimacy.
