Book excerpt: This collection builds on the foundational work of Penelope D. Johnson, John Boswell's most influential student outside queer studies, on integration and segregation in medieval Christianity. It documents the multiple strategies by which medieval people constructed identities and, in the process, wove the boundaries of inclusion and exclusion among various individuals and groups. The collection adopts an interdisciplinary approach, encompassing historical, art historical, and literary perpsectives to explore the definition of personal and communal spaces within medieval texts, the complex negotiation of the relationship between devotee and saint in both the early and the later Middle Ages, the forming of partnerships (symbolic, economic, devotional, etc.) between men and women across medieval Europe's considerable gender divide, and the ostracism of individuals and groups through various means including imprisonment, violence, and their identification with pollution. Contributors include: Diane Peters Auslander, Constance Hoffman Berman, Elizabeth A.R. Brown, Alexandra Cuffel, Anne M. Schuchman, Jane Tibbetts Schulenburg, Katherine Allen Smith, Kathryn A. Smith, Christina Roukis-Stern, Susan Valentine, Susan Wade, and Scott Wells.
