Another series of publications that came from the press of John Day, in 1574, were the writings of John Caius on the history and antiquities of the two Universities. They are generally found bound together in the following order:-- 1. De Antiquitate Cantabrigiensis Academiæ. 2. Assertio Antiquitatis Oxoniensis Academiæ. 3. Historia Cantabrigiensis Academiæ. 4. Johannis Caii Angli De Pronunciatione Græcæ et Latinæ linguæ cum scriptione noua libellus. The 'Antiquities' and 'History' of Cambridge were both books of considerable size, the first having 268 pages, without counting prefatory matter and indexes. The other two were little better than tracts, the one having only 27 and the other 23 pages. Some editions of the _De Antiquitate_ are found with a map of Cambridge, while the 'History' contained plates showing the arms of the various colleges. All four were printed in quarto. The type used for the text was in each case an Italic of English size, with a small Roman for indexes. The title-page was enclosed in a border of printers' ornaments, and the printer's device of the Heart was on the last leaf of two out of the four. Matthew Parker died in 1575, and the art of printing, as well as every other art and science, lost a generous patron. But Day's work was not yet done, though he printed few large books after this date. A very curious folio, written by John Dee, the famous astronomer, entitled _General and Rare Memorials concerning Navigation_, came from his press in 1577. This work had an elaborate allegorical title-page, by no means a bad specimen of wood-engraving. It was a history in itself, the central object being a ship with the Queen seated in the after part. In 1578 Day printed a book in Greek and Latin for the use of scholars, _Christianæ pietatis prima institutio_, the Greek type being a great improvement on any that had previously appeared. Indeed, it has been considered equal to those in use by the Estiennes of Paris. The year 1580 saw Day Master of the Stationers' Company. Two years later he was engaged in a series of law-suits about his _A B C and litell Catechism_, a book for which he had obtained a patent in the days of Edward VI. As we have already noted, the aim of the Corporation of the Stationers' Company was not primarily the promotion of good printing or literature. Printers were looked upon by the authorities as dangerous persons whom it was necessary to watch closely. Only six years after coming to the throne, Elizabeth signed a decree passed by the Star Chamber, requiring every printer to enter into substantial recognisances for his good behaviour. No books were to be printed or imported without the sanction of a Special Commission of Ecclesiastical Authorities, under a penalty of three months' imprisonment and the forfeiture of all right to carry on business as a master printer or bookseller in future, while the officers of the Company were instructed to carry out strict search for all prohibited books.
