MARCHESINUS, Johannes (b. c.1300). Mammotrectus super Bibliam. Venice: Franciscus Renner de Heilbronn and Nicholaus de Frankfordia, 1476.

First Venice edition of a popular guide to understanding the text of the Bible for priests. The Mammotrectus explains difficult Biblical words, church festivals, the legends of the saints, and various liturgical texts. The text was probably first printed in 1470 by Peter Schoeffer, and thus went into many subsequent editions, quite a few of which are in smaller formats such as this quarto printing—reflecting this work's use as a practical guide for priests and perhaps a desire for portability.
