Writers' lurid tales of their rulers' sex lives are a familiar part of our image of ancient Rome, but how reliable are these accounts and what can such stories tell us about Roman attitudes to sexual behaviour and morality? Drawing on twelve centuries of evidence from literature, inscriptions, graffiti, medical handbooks, legal texts, magic spells and frequently explicit visual arts, this wide-ranging account explores the Roman view of love, marriage, childbirth, homosexuality, prostitution and infidelity.
