Abstract
Near the end of his Euboean Discourse, Dio attacks prostitution because it encourages men to seek sexual pleasure from other sources as well, including youths from noble households. While some scholars find no evidence in this diatribe for Dio's revulsion against male-male sexual relations per se, others conclude that it does indeed reflect Dio's contempt for all sexual relations between men. This study considers afresh Dio's treatments of sexual relations between men in his Discourses, and concludes that Dio may endorse both male-male and male-female sexual relations when the agent initiating sexual contact pursues philia and eunoia. On the other hand, Dio expresses his disgust when the agent uses sexual relations self-indulgently for pleasure. The content and form of his arguments illustrate his familiarity with both Stoic doctrine and the forms of popular moralizing discourse. The paper first examines Dio's remarks in the third Discourse on Kingship, where he praises sexual relations in a measured way, indicating his familiarity with Stoic teachings on eros. Second, it considers Dio's remarks in the Euboean Discourse and supports John Winkler's argument that Dio objects to prostitution because it is rooted in self-indulgent pleasure-seeking. Dio's rhetorical approach reflects his awareness of popular teachings against self-indulgence typical of Cynic-Stoic diatribe. Third, the essay argues that Dio's remarks in the First Tarsian oration condemn adult male sexual passivity, not all aspects of sexual relations between males. Fourth, brief remarks in his Borystheniticus are not to be taken as evidence for Dio's hostility to sexual relations between men, though they possibly indicate his discomfort with how he imagines non-Greeks engage in sex
