the Book of Martyrs, Foxe records statements made in prison to Day by the future martyr John Rogers, "spake being then in prison, to the Printer of this present booke, who then also was layd up for lyke cause of religion". Perhaps because the flight of foreign Protestant workers under Mary was causing a shortage of printers, Day was released the next year and allowed to work again, but only as a jobbing printer. He reunited with Seres (also recently released from prison) to produce works of Catholicism for Catholic printer John Wayland, a far cry from the Protestant polemics he printed prior to imprisonment. He also served as the official printer of the City of London for two years. Elizabethan period With the death of Mary and the accession of Elizabeth I in 1558, Day's business blossomed once more. Day was already close to Cecil, who had now become one of the new Queen's top advisors. Through Cecil, Day was awarded the valuable monopoly on printing ABCs. He also befriended Robert Dudley (son of John Dudley), another of Elizabeth's favorites. With the help of his connections, Day was able to obtain a lucrative patent to print William Cuningham's Cosmographical Glasse. He produced the first edition in 1559 using a new italic font of the highest quality (probably cut by François Guyot) and a large number of impressive woodcuts. Day absorbed the high production costs himself, since he knew the work would solidify his reputation as a master printer. Day's patent to print Cuningham—his first under Elizabeth—gave him exclusive rights to the work for life; it also allowed him to retain a monopoly for seven years on any other original works that were not covered by other patents, were "compiled at Day's expense", and were "not repugnant to Holy Scripture or the law". This stipulation would be an important source of income for the rest of his life. Day took advantage of the monopoly clause, reestablishing his Edwardian patent for The ABC with Little Catechism. In 1559, he obtained a patent for The Whole Booke of Psalmes, Collected into English Meter, a metrical psalter, compiled mostly by Thomas Sternhold and John Hopkins, that Day first published in 1562. The Stationers' Company guaranteed Day the right to print all "psalmes in metre with note", in other words, psalms with music. Despite the fact that psalmes had usually been learned by rote,
