One of the most scandalous verses of Martial, devoted to the description of a feminine sexual intercourse (1.90.7 inter se geminos audes committere cunnos) show very close and unexpected resemblance to one of Alcimus Avitus’ De spiritalis historiae gestis (carm. 4.499 inter se tumidos gaudet conmittere fluctus). This paper presents and discusses the hypotesis that both authors imitate a very solemn, archaic model, namely that of Ennius’ Annales.
