We have a clearer indication of the period of the unknown printer in the fragments of his work that have been discovered in the cover linings of manuscript and printed books bound in the latter part of the fifteenth century. It is obvious that the fragments are older than the bindings, but it is not probable that they are much older, for no fragment has been found in any book made before the year 1467. The larger portion came from bindings made after 1470.
A copy of William of Saliceto on the Health of the Body contains a written memorandum or annotation to this effect: "This book was bought by Lord Conrad, abbot of this place, XXXIIII [?], who died in the year 1474." Conrad du Moulin was abbot between the years 1471 and 1474 only. Another inscription in the same book states that it once belonged to the Convent of St. James at Lille.[1] These inscriptions have been cited to show that the unknown printer preceded every other typographic printer in the Netherlands; but the precedence claimed is unimportant, for we know that Ketelaer and De Leempt printed books at Utrecht in 1473.
In a public library at Haarlem is a manuscript copy of a version of the Speculum in the Dutch language—an admirably illustrated book of 290 leaves of vellum—which contains these inscriptions: "This book was finished in the year of our Lord 1464, on the 16th day of July. … An Ave Maria to God for the writer. … This book belongs to Cayman Janszoen of Zierikzee, living with the Carthusians near Utrecht."[2] Van der Linde says that the text of the two editions in Dutch described on a previous page, is really an abridgment of the text of this Utrecht manuscript of 1464.
This fact established, the claim that the Dutch editions of the book were printed before this date becomes untenable. Nor is there positive evidence that the book was printed anywhere out of Utrecht. Utrecht was the residence of David, a prince of Burgundy and a notable patron of literature; it was also the residence of the bishop of the diocese; it had a
