The medieval treasure house, consisting of sacristy, vestry and treasure rooms was the depository for the ecclesiastical treasure belonging to a church, holy vessels, vestments, altar hangings, candlesticks and priceless liturgical books and reliquaries. It was carefully designed to convey the message of its status and function. A book devoted to these medieval museums which housed such precious materials is long overdue. Ironically, the interest in the objects that they conserved has often resulted in ecclesiastical treasure being removed to new museums, leaving their former places of protection in need of protection themselves.

Sacred treasuries formed part of every medieval cathedral or church housing contents that were endowed with profound spiritual significance but were also of immense value in worldly terms. In many ways, these were the predecessors of both modern museums and modern banks.

Mindful of already existing publications, the editors determined to foreground scholarly expertise and approaches to stained glass, as well as up-to-date bibliographies.

In Visual Culture and Politics in the Baltic Sea Region, Kersti Markus examines how visual rhetoric was used by the Danish rulers as an instrument in establishing supremacy in the region during the Baltic crusades.

The thousand years explored in this book witnessed developments in the history of Ireland that resonate to this day. Interspersing narrative with detailed analysis of key themes, the first volume in The Cambridge History of Ireland presents the latest thinking on key aspects of the medieval Irish experience. The contributors are leading experts in their fields, and present their original interpretations in a fresh and accessible manner. New perspectives are offered on the politics, artistic culture, religious beliefs and practices, social organisation and economic activity that prevailed on the island in these centuries. At each turn the question is asked: to what extent were these developments unique to Ireland? The openness of Ireland to outside influences, and its capacity to influence the world beyond its shores, are recurring themes. Underpinning the book is a comparative, outward-looking approach that sees Ireland as an integral but exceptional component of medieval Christian Europe.
