[Footnote II-29: In the catalogue of Dr. Kloss’s Library, No. 2024, is a “Historia et Apocalypsis Johannis Evangelistæ,” imperfect, printed from wooden blocks. The following are the observations of the editor or compiler of the catalogue: “At the end of the volume is a short note, written by Pope Martin V., who occupied the papal chair from 1417 to 1431. This appears to accord with the edition described by Heineken at page 360, excepting in the double _a_, No. 3 and 4.” If the note referred to were genuine, and actually written in the book, a certain date would be at once established. The information, however, comes in a questionable shape, as the English _rédacteur’s_ power of ascertaining who were the writers of ancient MS. notes appears little short of miraculous.] Upon extremely slight grounds it has been conjectured that the Biblia Pauperum, the Apocalypse, and the Ars Moriendi,--another block-book,--were engraved before the year 1430. The Rev. T. H. Horne, “a gentleman long and well known for his familiar acquaintance with books printed abroad,” says Dr. Dibdin, “had a copy of each of the three books above mentioned, bound in one volume, upon the cover of which the following words were stamped: Hic liber relegatus fuit per Plebanum. ecclesie”--with the date, according to the best of the Rev. Mr. Horne’s recollection, 142(8). As he had broken up the volume, and had parted with the contents, he gave the above information on the strength of his memory alone. He was, however, confident that “the binding was the ancient legitimate one, and that the treatises had not been subsequently introduced into it, and that the date was 142 odd; but positively anterior to 1430.”[II-30] [Footnote II-30: Bibliotheca Spenceriana, vol. i. p. 4, cited in Ottley’s Inquiry, vol. i. p. 99.]
