The majority of sources provide only incomplete insights into the life worlds of late medieval couples. How did spouses behave within their relationship and how did they present themselves as a couple to others? Beginning with the marriage ceremony and ending with the death of one partner, Nicole Matter-Bacon also examines the behavior of Zurich couples as parents, as a united front, in conflict, and in cases of infidelity. She relies on the court records of the city of Zurich from the 15th century, as there is no documentation of informal norms, unlike the formal rules of marriage that were recorded in city law and canon law. However, these informal norms can be reconstructed based on the behavior patterns of spouses in court—as plaintiffs, defendants, or witnesses. In this way, the author provides unprecedented insights.
