Of the twenty-five essays in this volume, most were published between 1961 and 2013, but four are printed here for the first time. They represent the work of a great and original scholar in Mediterranean history whose unflagging interest in Frederick II and his world consistently led him out into broader fields, which he always viewed in original ways. In an age often called that of papal monarchy and secular-minded rulers, Powell found popes with complex agendas and extensive pastoral concerns, a rather more Christian Frederick II, the human personnel and mechanics of the Fifth Crusade, the sermons of the devout urban layman Albertanus of Brescia, and Muslims under Christian rule. His studies here assert a continuity between the pontificates of Innocent III and Honorius III as well as the pragmatic necessity that only secular rulers could launch and direct crusading expeditions. His interest in the northern Italian communes relates their devotional culture to the ideals of virtuous government and communal identity. The devotional culture of the communes was to be the subject of his next book, now unfinished; several parts of it could be rescued and are now included here.
