This volume deals with shifts and changes that took place during the Middle Ages when things, or ideas, or writings, were transferred from time to time, place to place, or one ideological realm to another. The same objects, ideas, or texts changed their meaning, impact, or symbolic value according to different contexts. The twelve papers, written by leading experts, investigate the authority attributed to texts and their canonization in different contexts; the shifting uses and meanings of gifts, from honorable instruments in the settlement of disputes to corruption and bribery; and the transition of violence and power from relationships between equals to a tool for the maintenance of hierarchies. Contributors include: Gadi Algazi, Monique Bernards, Arnoud-Jan Bijsterveld, Esther Cohen, Valentin Groebner, Yitzhak Hen, Mayke de Jong, Rob Meens, Marco Mostert, Thomas FX Noble, Timothy Reuter, Hendrik Teunis, and Stephen D. White.
