This article re-analyses in detail the meaning of the expression ludi Graeci which appears in two of Cicero’s letters (Ad Fam. 7,1 and Ad Att. 15,5). A careful examination of the first instance reveals that ludi Graeci indeed referred to theatrical performances in Greek language and not merely to Latin plays that followed Greek models. A brief survey of contemporary epigraphical sources shows that no occurrence excludes this interpretation. The question of the apparent contradiction between Cicero’s philhellenism and his criticism of the ludi Graeci in the two letters is also addressed, in order to demonstrate that the two attitudes are not mutually exclusive.
