In this richly illustrated book religious historian Eamon Duffy discusses the Book of Hours" unquestionably the most intimate & most widely used book of the later Middle Ages. He examines surviving copies of the personal prayer books which were used for private domestic devotions & in which people commonly left traces of their lives. Manuscript prayers biographical jottings affectionate messages autographs & pious paste-ins often crowd the margins fly-leaves & blank spaces of such books. From these sometimes clumsy jottings viewed by generations of librarians & art historians as blemishes at best vandalism at worst Duffy teases out precious clues to the private thoughts & public contexts of their owners & insights into the times in which they lived & prayed. His analysis has a special relevance for the history of women since women feature very prominently among the identifiable owners & users of the medieval Book of Hours. Books of Hours range from lavish illuminated manuscripts worth a kings ransom to mass-produced & sparsely illustrated volumes costing a few shillings or pence. Some include customized prayers & pictures requested by the purchaser & others handed down from one family member to another bear the often poignant traces of a familys history over several generations. Duffy places these volumes in the context of religious & social change above all the Reformation discusses their significance to Catholics & Protestants & describes the controversy they inspired under successive Tudor regimes. He looks closely at several special volumes including the cherished " Book of Hours" that Sir Thomas More kept with him in the Tower of London as he awaited execution."
