While it does not include all the printers having presses at that time, yet, if we remember that under the Star Chamber decree of 1637 the number in London was strictly limited to twenty, it shows how rapid the growth of the trade was in those twelve years. Of the original twenty, only three seem to have survived the troubles and dangers of the Civil Wars--Bernard Alsop, Richard Bishop, and Thomas Harper, though the places of three more were filled by their survivors--Elizabeth Purslowe standing in the place of her husband, Thomas Purslowe; Gertrude Dawson succeeding her husband, John Dawson; and James Flesher or Fletcher in the room of his father, Miles Flesher. John Gresmond and James Moxon were type-founders, Henry Hills and John Field were appointed printers to the State under Cromwell, and Thomas Newcomb was also largely employed, and shared with the other two the privilege of Bible printing. Roger Norton was the direct descendant of old John Norton, who died in 1590. Of Roycroft and Simmons we shall hear a good deal later on, as indeed we shall of many others in this list. The only names that hardly seem to warrant insertion in the list as printers are those of John and Richard Royston. Although they were for many years stationers to King Charles II., we cannot hear of any printing-presses in their possession. With the quieter time of the Commonwealth, several notable works were produced, though the annual output of books was much below the average of the seven years preceding. Foremost among the publications of that time must be placed Sir William Dugdale's _Monasticon Anglicanum_, the first volume of which appeared in 1655. As a monument of study and research this book will always remain a standard work of English topography; and it was not unworthily printed. The preparation of the numerous plates for the illustrations, and the setting up of so much intricate letterpress, must have been a very onerous work. This first volume, a large and handsome folio, came from the press of Richard Hodgkinson, and was printed in pica Roman in double columns, with a great deal of italic and black letter intermixed. The types were as good as any to be found in England at that time, and the press-work was carefully done. The engravings were chiefly the work of Hollar, aided by Edward Mascall and Daniel King, and are excellently reproduced. The whole work occupied eighteen years in publication, the second volume being printed by Alice Warren, the widow of Thomas Warren, in 1661, and the third and last by Thomas Newcomb in 1673; but these later volumes differed very little in appearance from the first, the same method of setting and the same mixture of founts being adhered to.
