This volume focuses on aspects of Carthusian history and culture of the later Middle Ages, a period of growth and vitality within the order. There is a primary but not exclusive focus on the English Province, which to date has received at best unbalanced attention. While the fundamental ambitions and ideals of Carthusianism formulated, articulated, and lived by the disciples of St Bruno between the late eleventh and the thirteenth centuries changed very little, the fourteenth to sixteenth centuries witnessed developments stimulated by and often commensurate with the progress of external culture. In such areas as devotional practice, literature, art and architecture, patronage, and monastic-lay relations generally, the houses of the order grew increasingly sophisticated: in some cultural spheres Carthusians were in the vanguard. The late Middle Ages thus offer rich opportunities for assessment of how a religious organization defined and justified by essentially reactionary conventions responded to constant forinsec evolution.The volume’s approach is multi-disciplinary, involving both senior and younger Carthusian scholars in investigation of the main facets of Carthusian life for which significant data survives. This permits a thorough analysis of the order’s character, one that reflects concern with synoptic understanding of medieval Carthusianism rather than partial assessment through a specifically devotional, literary, or more narrowly historical approach. Subject areas covered include the historical growth of individual Charterhouses, patronage of Carthusians by secular agents, Carthusian architecture and manuscript decoration, devotional practice, and textual culture.
