In 1480, printing was introduced into London by John Lettou, perhaps a native of Lithuania, of which Lettou is an old form. The first product of the press was an edition of John Kendale’s Indulgence asking for aid against the Turks, another edition having just been issued by Caxton in his large No. 2* type. As we have said, Lettou’s small neat type was very much better suited for printing indulgences, and its appearance very probably caused Caxton to make his small type No. 4, which he used in future for such work. Besides two other editions of the indulgence, Lettou printed only one book in this year, the _Quæstiones Antonii Andreæ super duodecim libros metaphysice Aristotelis_. It is a small folio of 106 leaves, of very great rarity, only one perfect copy being known, in the library of Sion College, London. In 1481 another folio book was printed, _Thomas Wallensis super Psalterium_, and probably in the same year a work on ecclesiastical procedure, known only from two leaves which were found in the binding of one of the Parker books in Corpus Christi College, Cambridge. From the workmanship of these books we can clearly see that Lettou was a practised printer, though we know nothing as to where he learnt his art. His type, which bears no resemblance to any other used in England, is very similar to that of Matthias Moravus, the Naples printer; so similar, indeed, as to make it certain that there must have been some connexion between the two printers, or some common origin for their types. Lettou was assisted by a certain William Wilcock, at whose expense the two large books were printed. About 1482, Lettou was joined by another printer, William de Machlinia, a native no doubt of Malines in Belgium. These two printers employed a new fount of type of the same school as the other English types, and one suitable for the printing of the law-books, which were their sole productions. In partnership they printed but five books, the _Tenores Novelli_, the _Abridgment of the Statutes_, and the _Year-Books_ of the 33rd, 35th, and 36th years of Henry VII. The first of these books is the only one which has a colophon. It gives the names of the two printers, and states that the book was printed in the city of London, ‘juxta ecclesiam omnium sanctorum;’ a rather vague address, since, according to Arnold’s Chronicle, there were several London churches thus dedicated. After these books had been issued, about 1483-84, John Lettou disappears, and Machlinia carried on his business alone. By himself he printed at least twenty-two books or editions. Out of all this number only four contain his name, and not one a date. He printed at two addresses, ‘By Flete-brigge,’ and in Holborn. If these two addresses refer to two different places, and we have no reason for supposing the contrary, there is no doubt that ‘By Flete-brigge’ is the earlier.
