It does not follow that because Day's name occurs in the charter that he was in England in 1556, but he certainly was so in the following year, for there is a Sarum Missal of that date with his imprint, besides several other books, including Thomas Tusser's _Hundred Points of Good Husserye_ (_i.e._ Housewifery); William Bullein's _Government of Health_, and sundry proclamations. But it was not until 1559 that his books began to show that excellence of workmanship that laid the foundation of his fame. In that year he issued in folio _The Cosmographicall Glasse_ of William Cunningham, a physician of Norwich. As a specimen of the printer's art this was far in advance of any of Day's previous work, and, moreover, was in advance of anything seen in England before that time. The text was printed in a large, flowing italic letter of great beauty, further enhanced by several well-executed woodcut initials. Amongst these was a letter 'D,' containing the arms of the Earl of Leicester, to whom the work was dedicated. There were also scattered through the book several diagrams and maps, a fine portrait of the author, and a plan of the city of Norwich. Some of these illustrations and initials were signed J. B., others J. D. The title-page was also engraved with allegorical figures of the arts and sciences. There can be very little doubt that Day had spent his time abroad in studying the best models in the typographical art. Students and lovers of good books may well pay a tribute to the memory of that scholarly churchman, who rescued so many of the books that were scattered at the dissolution of the monasteries, and enriched Cambridge University and some of its colleges by his gifts of books and manuscripts. But Matthew Parker did not stop short at book-collecting. He believed that good books should be well printed, and on his accession to power under Elizabeth, he encouraged John Day and others, both with his authority and his purse, to cut new founts of type and to print books in a worthy form. In 1560 Day began to print the collected works of Thomas Becon, the reformer. The whole impression occupied three large folio volumes, and was not completed until 1564. The founts chiefly used in this were black letter of two sizes, supplemented with italic and Roman. The initials used in the _Cosmographicall Glasse_ appeared again in this, and the title-page to each part was enclosed in an elaborate architectural border, having in the bottom panel Day's small device, a block showing a sleeper awakened, and the words, 'Arise, for it is Day.' At the end was a fine portrait of the printer. Another important undertaking of the year 1560 was a folio edition of the _Commentaries_ of Joannes Philippson, otherwise Sleidanus. This Day printed for Nicholas England, the fount of large italic being used in conjunction with black letter.
