This volume is the result of many years of research by both authors on the medieval tile industry that flourished in Anglo-Norman Ireland. After an introductory discussion of previous studies, part I of the main work commences with a brief outline of the English tile industry. This is followed by a comprehensive account of the Irish tiles, detailing the evidence for their manufacture, the main types and decorative techniques, distribution patterns, etc. Part II gives a full inventory of the 88 sites where tiles have been located followed by a descriptive catalogue and complete visual index of the 505 known designs reporoduced at one-third actual size. The corpus includes a number of colour and black and white plates depicting pavements in situ and some of the more striking designs. An appendix by M.J. Hughes and J. Cherry summarises the results of comparative tests on tiles from Ireland and Chester. Finally, a bibliography and a site index are provided. The volume is a major contribution to Irish medieval studies of value not only to archaeologists and historians but to students of art and design.
