Chapter 5 examines indigenous sexual ideology and attitudes based on the analysis of Mesoamerican metaphors and symbols that were used to discuss and represent sexual matters. The chapter shows that the principal concern in these texts was the necessity for moderation in sexual relations. Excessive intercourse, adulterous relations, and the use of aphrodisiacs could all lead to impotence, illness, and violence. Flowers, food, feathers, speech, and sight were invoked in metaphors and as symbols to represent sexuality in alphabetic and pictorial texts. They continued to resonate in the narratives and actions of indigenous people in colonial times. Chapter 5 considers how Spanish friars adopted some indigenous concepts in their efforts to promote Christian morality, and in turn how Spanish mores, Christian teaching, and colonial law affected native sexuality. The chapter argues, however, that Spanish Christian values regarding morality and sexuality influenced, but did not completely change, indigenous attitudes and practices.
