1 scholars have traditionally opted for units of study comprising distinct cultural and political entities, such as ‘Classical Greek,’ ‘Hellenistic,’ or ‘Roman’ associations. Occasionally, though, Greek and Roman traditions for associating have been treated as an implicit case of Mediterranean institutional unity, constituting one overarching fenomeno associativo, ‘associational phenomenon’.2 Thus, particularly the older historiography of the subject reflects this basic premise of wider Greco-Roman institutional connectedness and compatibility, in that even though the two subjects are most often dealt with separately, they are assumed to add up to a mutually coherent framework for interpreting one or the other or both.
