Despite the considerable number of private associations attested in the Peloponnese, epigraphic sources from this region only rarely allow us an insight into norms of the associations’ internal organisation. Beyond a regulation for the use of an hestiatorion, ‘banquet-hall’, and a chalkion (in this context the term probably refers to ‘bronze cooking utensils’ or the place where they were stored) on a metal tablet from Sicyon (sixth/fifth century BC), which is followed by a list of seventy-three male names,1 and an extremely fragmentary inscription from Mantinea,2 which refers to a nomos and to imposition of fines, texts of this type are not preserved. Some indirect light on private associations’ rules and regulations is further shed by a small number of honorific decrees originating in Peloponnesian towns. This chapter will focus on this category of texts from Mantinea.
