Publicly performed rituals and ceremonies form an essential part of medieval political practice and court culture. This applies not only to western feudal societies, but also to the linguistically and culturally highly diversified environment of Byzantium and the Mediterranean basin. The continuity of Roman traditions and cross-fertilization between various influences originating from Constantinople, Armenia, the Arab-Muslim World, and western kingdoms and naval powers provide the framework for a distinct sphere of ritual expression and ceremonial performance. This collective volume, placing Byzantium into a comparative perspective between East and West, examines transformative processes from Late Antiquity to the Middle Ages, succession procedures in different political contexts, phenomena of cross-cultural appropriation and exchange, and the representation of rituals in art and literature.
