1. Early drafts of this paper were improved immensely thanks to the careful and generous comments of Kristi Upson-Saia and Julie Kelto Lillis, and Julie's students in her “Virgins and Virginity in Early Christianity” seminar at the University of Virginia. I am also grateful for the comments and suggestions of the two anonymous readers for the journal, and the audience at the 2016 annual meeting of the North American Patristics Society, where I delivered a draft of the paper.

Fischer, “Abstention from Sex and Other Pre-Game Rituals Used by College Male Varsity Athletes,” Journal of Sport Behavior 20.2 (1997): 176–84 provides evidence of the belief's continuing influence in modern athletics. On the excesses typically associated with athletes in Greco-Roman antiquity, see Pierre Villard, “Le régime des athlètes: vivre avec une santé excessive,” in Thérapies, médecine et démographie antiques, ed. Christine Didier, Jean-Nicolas Corvisier, and Martine Valdher (Arras: Artois Pr. Université, 2001), 157–70.
