WÜRDTWEIN, Stephan Alexander. Bibliotheca Moguntina. Libris saeculo primo typographico Moguntiae impressis instructa.... Augsburg: Christoph Friedrich Bürglen, 1787. 4o. 9 engraved plates (3 folding) and 2 engraved illustrations in text. (Light browning and staining throughout.) Contemporary boards, uncut (worn). FIRST EDITION. "Würdtwein, a scholar of Worms, published a work of great interest on the origin of printing... He treats with considerable minuteness of the genealogy of Gutenberg, of Fust and of Peter Schoeffer, and engraves their arms and crests. He has copied, with the utmost veri-similitude, the colophons of all the early Mayence editions to which he could obtain access. Especially admirable is his facsimile of portions of the Psalter of 1457 which reproduces in exact size all the peculiarities of the original, as well as the system of abbreviation and punctuation adopted." Bigmore & Wyman vol. III, p. 100; Brunet V:1483. [With]: Another copy, dated 1789. Modern half vellum. (2)
