Among the documents used by Strype when writing his life of Archbishop Parker was a catalogue of the books bequeathed to Corpus Christi College by the archbishop, in which was an entry: “Rhetorica nova, impressa Cantab, fo. 1478.” This entry was communicated by Strype to Bagford, then collecting materials for a history of printing, and Bagford in his turn wrote about it to Tanner. Tanner’s brother passed on the information to Ames, who inserted it at the head of his account of Cambridge printing, and from him it was copied by other writers, including Herbert. In the meanwhile Conyers Middleton in his _Dissertation concerning the origin of Printing in England_, had turned the error into a new groove. Describing the edition printed at St Alban’s in octavo in 1480, he remarks: “The same book is mentioned by Mr Strype among those given by Archbishop Parker to Corpus Christi College in Cambridge; but the words, ‘Compilata in Universitate Cantabrigiæ,’ have drawn this learned antiquary into the mistake of imagining that it was printed also in that year at our University, and of doing us the honour of remarking upon it; so ancient was printing in Cambridge!” If the University Librarian, as Middleton then was, in place of being facetious, had stepped down the street and examined the book for himself, much subsequent confusion would have been avoided. He must have had a poor opinion of Strype if he supposed that that learned antiquary would describe as a folio printed at Cambridge in 1478 an octavo with a printed colophon, “impressa apud Villam Sancti Albani. 1480.” But Middleton’s plausible suggestion seems to have gained ground, and the Corpus volume was passed over as a copy of the St Alban’s book until 1861, when Bradshaw, at work on the manuscripts in the library accidentally met with it, and saw at once that it was not the St Alban’s book, but an unknown Caxton edition. It has no colophon, so that the concluding words “Compilata in Universitate Cantabrigiæ,” and the date 1478, might well deceive a casual observer into thinking it was printed at Cambridge in that year. Printing was introduced into Cambridge at the beginning of the year 1521 by John Lair of Siberch or Siegburg, a town a few miles south-west of Cologne. Like most of the foreign printers settled in England, he made but little use of his proper surname, but used the place name instead and called himself John Siberch. Nothing is known as to the date of his settling in Cambridge, but it was probably in 1519 or early in 1520, for in May of the latter year an edition of Richard Croke’s _Introductiones in rudimenta Græca_ was printed for him by Eucharius Cervicornus at Cologne.
