John Day (or Daye) ( – 23 July 1584) was an English printer. He specialised in printing and distributing Protestant literature and pamphlets, and produced many small-format religious books, such as ABCs, sermons, and translations of psalms. He found fame, however, as the publisher of John Foxe's Actes and Monuments, also known as the Book of Martyrs, the largest and most technologically accomplished book printed in sixteenth-century England.

Day rose to the top of his profession during the reign of Edward VI (1547–1553). At this time, restrictions on publishers were relaxed, and a wave of propaganda on behalf of the English Reformation was encouraged by the government of the Lord Protector, Edward Seymour, 1st Duke of Somerset. During the reign of the Catholic Queen Mary I, many Protestant printers fled to the continent, but Day stayed in England and continued to print Protestant literature. In 1554, he was arrested and imprisoned, presumably for these illicit printing activities. Under Queen Elizabeth I, Day returned to his premises at Aldersgate in London, where he enjoyed the patronage of high-ranking officials and nobles, including William Cecil, Robert Dudley, and Matthew Parker. With their support, he published the Book of Martyrs and was awarded monopolies for some of the most popular English books, such as The ABC with Little Catechism and The Whole Booke of Psalmes. Day, whose technical skill matched his business acumen, has been called "the master printer of the English Reformation".

Early career

Day's origins and the events of his early life remain obscure. Scholars have assumed that Day was born and raised in Dunwich, but there is no direct evidence that proves this claim. He may have been in London by 1540, as his name is mentioned in a city deposition as being a former servant of the printer and physician Thomas Raynalde. In 1546, he was probably one of twenty men who were granted the freedom of the city by redemption to work for the Stringers' Company of London.

The next year, he began printing with a partner, William Seres; the two based their operations at the parish of St Sepulchre in London. Day and Seres specialised in religious works, such as those by Robert Crowley, which were largely related to theological controversies of the time. The Protestant Reformation was advancing rapidly, and the laws against the publication of heretical works were being relaxed. In 1548, ten of the twenty works that the two men published were devoted to criticizing the Catholic belief of transubstantiation. Day and Seres also translated important works of Continental Protestantism for the English market, notably Herman von Wied's A Simple and Religious Consultation in 1547.

In 1549, Day opened a new shop in Cheapside, and the next year, he and Seres were successful enough to amicably separate their businesses. Day set up his new home and printing establishment at Aldersgate in the parish of St Anne and St Agnes and transferred from the Stringers' to the Stationers' Company. Day found Aldersgate's foreigner-friendly attributes helpful in attracting skilled Dutch workers, whom he relied on throughout his career. The next year, he secured a valuable patent to print the works of John Ponet and Thomas Beccon. This enraged one of his competitors, Reginald Wolfe, who already held a patent to print Ponet's Catechism in Latin. Eventually, a compromise patent was issued which allowed Wolfe to continue printing the Catechism in Latin and Day to print the work in English. and that he continued to print Protestant polemical works under the pseudonym Michael Wood. The "Michael Wood" pamphlets included Protestant writings by Lady Jane Grey, John Hooper, and Stephen Gardiner, and attacks on Mary and her advisors.

On 16 October 1554, according to the diary of Henry Machyn, Day was caught and sent to the Tower of London for printing "naughty books". In 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. 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. and were "not repugnant to Holy Scripture or the law". 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 psalms had usually been learned by rote, the business proved lucrative, reflecting a rise in musical literacy during the period. The Whole Booke of Psalmes became the period's best-selling book and the standard English psalter of its time. There is a tradition that Foxe, who revised and added material while the book was being set in type, actually lived at Day's shop at Aldersgate during the production of the book; he certainly received correspondence there and visited regularly. Day heavily invested time and money in the production of Foxe's book, the largest publishing project undertaken in England to that time, and he took an active part in the compilation of the material. Day used changes in type sizes or fonts to distinguish Foxe's editorial insertions from texts of his sources. The resulting lavish folio filled with woodcuts was an expensive luxury item, but it sold well and Day profited from his investment.

Day continued to take on challenging and difficult projects. He had already printed the first English book of church music in 1560. In 1567, Matthew Parker, the Archbishop of Canterbury, commissioned Day to print a collection of writings attributed to the tenth-century Aelfric of Eynsham. For this work, Day, known for his fine and varied fonts, had the first-ever font of Anglo-Saxon type cut. The cost was borne by Parker, perhaps Day's most important patron. The font may have been designed by François Guyot, a French type-founder known to have worked for Day and lived in his household. Day used the same font to print Lambarde's Archaionomia (a collection of Anglo-Saxon laws) in 1568. In 1570, he printed Billingsley and Dee's English Euclid, which included folding and movable diagrams—one of the first printed books ever to do so. In the same year, he printed Ascham's Scholemaster.

Day and Foxe completed a second edition of the Book of Martyrs in 1570. It was even larger than the first—a total of 2,300 pages in two enormous folio volumes—and at one point, Day ran out of paper (which he imported) and had to paste smaller sheets together to make do. This edition received official recognition: William Cecil and the Privy Council directed the church to ensure that copies were available to parishioners, and in 1571, the Convocation ordered that every cathedral church and the household of every senior member of the clergy should own a copy. The edition has been recorded as costing sixteen shillings, roughly equivalent to two months' wages for a skilled London clothworker at the time.

Final years and legacy

By the late 1570s, there was open discontent among the less wealthy members of the Stationers' Company about Day's extensive patents. He was compelled to go to court against printers who pirated works to which he owned the rights. Among those brought to trial was Roger Ward, who admitted to pirating 10,000 copies of ABC with Catechisms in a font which imitated Day's. It was Wolfe who led a group of "poor printers", as they called themselves, in a campaign against the patents in the late 1570s. As a result of an official investigation, Day was eventually obliged to concede certain titles to the Company for the benefit of the poorer printers, but he kept the titles he printed most.

In 1580, Day became Master of the Stationers' Company, and focused vigorously on defending the industry against piracy. His official powers included the right of "search and seizure", which he did not hesitate to exercise on behalf of the trade or to further his own interests. In 1584, he sent men to break into Wolfe's premises and destroy any materials relating to suspected piracy. Four years before, he had even destroyed his son Richard's printing equipment after Richard had printed the ABC and the Psalmes without his permission. Though Richard was technically co-patentee of these titles, John Day pursued him into the courts and all but destroyed his printing career.

In 1582, Day's health began to deteriorate quickly. Though weakening, he raced to complete another edition of Actes and Monuments in 1583, printing it on at least four presses. It was unusual for books of this size and ambition to go beyond one or two printings. Holinshed's Chronicles, the only book of the time to rival the Book of Martyrs in scope and reputation, never went into a third edition.

Day died on 23 July 1584 at Walden in Essex. He married twice and fathered twenty-four children. His eldest sons by his first marriage was Richard (b. 21 December 1552) and Edward, while his eldest sons by his second wife, Alice, was John (religious) and Lionel (studious).
