This Handbook is a landmark academic collection that presents cutting-edge interpretive perspectives on medieval religion for a wide academic audience, drawing together thirty key scholars in the field from the United States, the UK, and Europe. Notably, the Handbook is arranged thematically, and focusses on an analytical, rather than narrative, approach, seeking to demonstrate the variety, change, and complexity of religion throughout this long period, and the numerous different ways in which modern scholarship can approach it. While providing a very wide-ranging view of the subject, it also offers an important agenda for further study in the field.
