The popularity of this prayer in the books of times earlier than ours is well shown in accounts of the lives and deaths of the English Martyrs, that is, of those saints who were put to death for their Faith between the years 1535 and 1681. In those days, when the alleged activities of the Stationers’ Company made all Catholic printing and book-selling contraband, we find repeatedly that ’Manuals of Devotion’ were found in the presses of the intrepid printers, or that in the search through their houses the pursuivants found ‘divers psalters’. So it was with Carter and Webley, with Collins and Duckett; all truly martyrs. The books were often proclaimed our Lady's psalters, meaning what were also called Books of Hours; perhaps because the new man-made religion so ignored our Lady that her faithful children were all the more dedicated to her service. Often too the books used by these hunted. Catholics had in them the Psalter of Jesus, in English as we have it now.
