This is a collection of original essays on topics from the twelfth to the twentieth centuries. The subjects include the history of medieval Dublin, the medieval Irish Church, Ireland in French Arthurian romances, English law in Ireland, urban institutions in medieval Europe, medieval Irish and Continental scholarship, a previously unknown royal portrait, an Irish archbishop's controversy with the friars, humanism in fourteenth-century Florence, the Reformation in England and Hungary, the Counter-Reformation in France, Spain and Ireland, piety in nineteenth-century England and Ireland, and the historiography of the 1916 Easter Rising. The authors are a distinguished group of scholars based in Ireland, England, Austria, Germany and the United States, who were pupils, colleagues and friends of F. X. Martin, who was Professor of Chair of Medieval History from 1962 until his retirement in 1988. The range of the resulting volume does justice to that of F. X. Martin's own interests and to the importance of his contributions to historical scholarship.
