Among the 200 odd books which Richard Pynson printed between 1493 and 1527, we find six Marks (besides variants), of which five are very similar, and of these we give two examples, the smaller being one of the earliest, in which it will be noticed that the drawing is much inferior to the larger example; the sixth Mark is a singular one, consisting of a large upright parallelogram surrounded by a single stout line, within which are the scroll, supporters, shield and cypher, crest, helmet and mantling, and the Virgin and St. Catherine, and in many other particulars differing from the other five examples. Robert Redman, who, after quarrelling with Richard Pynson, and apparently succeeding him in business, employed a device almost identical with that which Pynson most frequently used, and to which therefore we need not further refer. In chronological sequence the next English printer who employed a device is Julian Notary, who was printing books for about twenty years subsequent to 1498, first at Westminster, then near Temple Bar, and finally in St. Paul’s Churchyard. He had two devices (of which there are a very few variations), of which we give the more important. The other has only one stout black line, and not two, and it has also the Latinized form of the name--Julianus Notarius. About two dozen different works of this printer are known to bibliographers. In connection with Notary, we may here conveniently refer to an interesting, but admittedly inconclusive article which appears in _The Library_, i., pp. 102-5, by Mr. E. Gordon Duff, in which that able bibliographer publishes the discovery of two books which would point to the existence of an unrecorded English printer of the fifteenth century. One of these has the title of “Questiones Alberti de modis significandi,” and the other, of which only a fragment is known to exist, is a Sarum “Horæ,” which is dated 1497. In the colophons of neither does the name of the printer transpire, but his Mark is given in both--in the former book in black, and in the latter in red. This mark is identical with Notary’s, with this important exception, that, whereas in Notary’s device his name occurs in the lower half of the device, in these the lower half is occupied by the initials I. H., and the upper half by the initials I N B, the I N being in the form of a monogram, and not distinct. In 1498 this same block was used on the title-page of the Sarum “Missal,” printed by Notary, who altered it to suit his own requirements. We cannot follow Mr. Gordon Duff in his conjectures as to the probability of who this unknown printer may have been, but the matter is one of great bibliographical interest. William Faques, who was the King’s Printer, and who is known to have issued seven books between 1499 and 1508, had only one Mark, which is totally different from those of any of his predecessors, as may be seen from the example given on page 16, where will also be found references to the
