Book excerpt: Reflecting the diverse interests of Jean-Michel Spieser, his colleagues, students and friends contribute papers focused on topics ranging from the changing role of the apse and the layout of late antique basilicas to holy relics said to have been brought from Constantinople. Many of the articles address the nature and impact of specific media - goldsmiths' work, ivory and ceramics - while a group of highly original, broader studies is devoted to such larger issues as ritual display in the tenth century, the metaphorical significance of pottery and an interrogation of the supposed influence of Byzantine icons on Western medieval art. Throughout, the achievement of the authors is to move from concrete observations of particular objects to the larger meaning they held for those who commissioned and made use of them.
