Iconoclasm, the debate about the legitimacy of religious art that began in Byzantium around 730 and continued for nearly 120 years, has long held a firm grip on the historical imagination. Byzantium in the Iconoclast Era is the first book in English to survey the original sources crucial for a modern understanding of this most elusive and fascinating period in medieval history. It is also the first book in any language to cover both the written and the visual evidence from this period, a combination of particular importance to the iconoclasm debate. The authors, an art historian and a historian who both specialise in the period, have worked together to provide a comprehensive overview of the visual and the written materials that together help clarify the complex issues of iconoclasm in Byzantium.
