Scholars have regularly debated the question of how the Galli, priests of Magna Mater/Cybele, fit into the Roman social milieu. Several have argued (citing Domitian’s legislation) that membership of the Galli was restricted to foreign citizens, whilst others have argued that the chief priests—the Archigalli—were Roman citizens, while the ‘lower’ Galli were non-citizens, thus separating the Galli and the Archigalli within the Cybele cult. These views remain prevalent in modern discussions on the cult, and have not undergone significant scrutiny or analysis. By assessing these views as well as the existing material and literary evidence for the Galli, this article argues that the Archigalli and the Galli were indistinct in terms of behaviour and affiliation. Moreover, this article uses archaeological and literary evidence to suggest that the Galli most likely included Roman citizens among their members, contrasting with the prevailing view of them as foreign residents in Rome.
