Having obtained some type Siberch started to work for himself, and his first production was a speech of Dr Henry Bullock delivered before Wolsey when the Cardinal visited the University in the autumn of 1520. This is a small pamphlet of eight leaves, devoid of all ornament, and it was published between February 13, the date of the dedication and the end of the month, in 1521. The type used appears to be new, but where it was obtained is not settled. It bears a very strong resemblance to some of Pynson’s, but is not quite identical. At present we do not know much about the early business of type-cutting, but it seems clear that, soon after the commencement of the sixteenth century, different printers went to a common source for their type, and that type-cutting was not a part of the printer’s business, as it was when printing was first invented, but a special trade. New types would thus tend to conform more to a common model. Of this first Cambridge book four copies are known, but unfortunately there is no copy in Cambridge, the four copies being in the British Museum, the Bodleian, the Lambeth Library, and Archbishop Marsh’s Library, Dublin. The Bodleian copy had belonged to Richard Burton, the author of the _Anatomy of Melancholy_, the Lambeth one to Archbishop Bancroft, so that at any rate for a few years, between 1646 and 1662, this latter copy was with the rest of the Archbishop’s books upon the shelves of the University Library. About April, in 1521, according to Bradshaw’s calculation, Siberch’s second book appeared, the sermon of Augustine, _De miseria ac brevitate vitæ_, a book of twelve leaves. The printer had added a little to his stock of type, for there is a Greek motto on the title-page which is also enclosed between two border-pieces. This type is interesting as the first genuine moveable Greek type used in England. A year or two earlier W. de Worde had introduced a few words of Greek into an edition of one of Whitinton’s Grammars, but the words were roughly cut on wood. Pynson did not begin to use Greek until 1524 in a work by Linacre, and in the preface he offers a curious apology for its imperfections, praying the reader to pardon missing breathings or accents, since he had but recently cast the Greek types and had not prepared a supply sufficient to finish the work completely. The amount of Greek printing in all Siberch’s books put together is very small, hardly enough to call for the cutting of a special fount, for it must be borne in mind that a Greek fount is infinitely larger and more complex than a Roman. One specially complicated fount used at Venice in 1486 contained about 1350 sorts. It seems probable therefore that we must look to some foreign source for this type, and its identification might throw some further light on Siberch’s business career.
