It appears that in that year, at the time when Day removed his shop from {97} Aldersgate to St. Paul’s Churchyard, Archbishop Parker was engaged in providing replies to a Popish polemic of Nicholas Sanders, entitled _De Visibili Monarchia_. Dr. Clerke of Cambridge was selected for the task, and his _Responsio_ was entrusted to Day to print. In a letter to Lord Burleigh, dated December 13, 1572, the Archbishop thus refers to the typography of the forthcoming work[170]: “To the better accomplishment of this worke and other that shall followe, I have spoken to Daie the printer to cast a new Italian letter, which he is doinge, and it will cost him xl marks; and loth he and other printers be to printe any Lattin booke, because they will not heare be uttered and for that Bookes printed in Englande be in suspition abroad.” Strype, referring to the transaction, adds a note: “For our Black English letter was not proper for the printing of a Latin Book; and neither he (Day) nor any one else, as yet had printed any Latin books.”[171] This misleading statement is corrected by Herbert,[172] who points out that many Latin books had been printed, few of which, after 1520, had been in Black-letter, and he believed none at all after 1530. Moreover, many English books had long before 1572 been printed in Roman or Italic, and even such as had generally been printed in Black-letter usually had the notes and quotations in Roman or Italic. It is singular that, after this announcement by the Archbishop, neither of the replies to Sanders was printed in Italic type. Clerke’s _Responsio_,[173] in 1573, appeared in a new Great Primer Roman type, with the quotations only in Italic, the headings being set in the large Italic afterwards used in the _Asser_. Acworth’s _De Visibili Romanarchia_,[174] another rejoinder, in the same year, was in an English Roman, with a corresponding Italic and Greek. In Parker’s great work, however, _De Antiquitate Britannicæ Ecclesiæ_,[175] published the year before (1572), and supposed by some to have been printed by Day at a private press of the Archbishop’s at Lambeth, the entire text, consisting of 524 pages, was in the English Italic, which Dibdin describes as “a full-sized, close, but flowing Italic letter.” The preface only to this work was in Roman; the various titles and sub-titles being in the larger founts of the _Responsio_ and _Asser_. Day was among the first English printers who cut the Roman and Italic to range as one and the same fount. Hitherto the two letters had been but seldom {98} intermixed, and when they were, they frequently exhibited a disparity in size and an irregularity in line which was disfiguring.[176] Day, however, cut uniform founts.
