John Grierson, Provincial of the Dominican Order in Scotland from 1523 until the Reformation, is recorded in Early Scottish Libraries as the owner of twenty-one books.1 To them may be added a copy of Aristotle: Opera omnia, cum commento Auerrois, Venetijs, per Bernardinum de Tridino de Monteferato, 1488-9, kept at Bristol Central Library.2 It was one of a number of books and manuscripts presented between 1613 and 1628 by Tobias Matthew, Archbishop of York, to the public library of his native city;3 how it came into his possession is not known. It is inscribed at al verso at the end of column i ' Codex in vsu fr(atr)is ioha(n)nis gresone ordinis predicator(um)' in a small neat hand (repeated, with variations, several times throughout), and, in a much larger hand ' Codex pro Usu ffratris Joha(n)nis Gresoni Posthac spectatur(us) ad co(mmun)it(at)em co(n)ue(n)tus ci(vita)tis sanctiandr(eae).' At the end of nnn4 verso, it is inscribed ' Pro vsu ffr(atr)is Joh(annis) Gresonj' in the same large hand, and further up, at the end of column i, in a somewhat smaller hand, ' Liber ordinis fr(atru)m p(rae)dicatorum ex opera fratris iohannis gresoni': the inscription is difficult to read as a scrap of paper, presumably a fragment from some contemporary printed work, has been pasted over it. This fragment consists of a pair of woodcuts, depicting respectively, a knight (possibly an unidentified saint) holding a bow in his left hand and two arrows in his right hand, and St Francis of Assisi, kneeling, receiving the stigmata. A light brown ink-wash has been rather clumsily added to the greater part of both pictures, a dull red to the knight's hat and a bright orange to the halo of St Francis. An unsuccessful attempt to lift the fragment has been made at some time: this has revealed part of the inscription, but has also somewhat damaged both pictures. The volume was rebound in the nineteenth century, apparently preserving the original boards in new leather, upon which a design is blind-stamped, possibly in imitation of the original. The surviving metal guards on the edges of the boards have been reattached, and new ones added to replace those that had been lost. Two clasps are attached to
