This chapter discusses social concepts, notions and assumptions that prevailed in the ancient Near East concerning human sexuality. Its introduction supplies chronological, geographical, and cultural definitions to explicate what is meant by the term ‘ancient Near East’, and expands on the sources of information used in the chapter, their contributions and limitations. The introduction also elaborates on the categories and aspects of human sexuality discussed in the chapter. Subsequently, the chapter is organized thematically. Each theme focuses on a specific category of sexuality, which is discussed according to the pertinent sources of information available to us, including legal, literary, cultic, and others. The categories surveyed in the chapter are: Sex and Reproduction, Sex and the Body, Gender Norms and Inequality, Sex and Marriage, Sex and Slavery, Sex and Politics, Sex and Religious and Cultic Practices, and Sex and Criminal Law. The chapter demonstrates how different textual genres reflect the role of sexuality in ancient Near Eastern societies: official law regulated sexual behaviour, literary texts echoed social norms, and cultic texts related to a variety of matters that involved human sexuality. The chapter highlights topics such as male privilege and gender inequality, social hierarchy, and cultural differentiation.
