On the Purification of Women: Churching in Northern France, 1100-1500 (2011)

This book is a social history of the ritual and custom of churching, a liturgical rite of purification after childbirth performed on a woman's first visit to church after giving birth. The book describes the development of the rite from its original meaning as a response to blood pollution to its redefinition as a rite that honoured marriage.
