The first contains the 493 "decisiones novae" collected by Guillaume Horboch (c. 1320-1384), who was a doctor of canon law at the universities of Avignon and Bologna, and a member of the tribunal de la Rote, one of the three courts of the Roman Catholic Church. The 887 "decisions antiquæ" follow.

It is repeated on folio a1 recto, also printed in red and black, with another frame. Each decisiones begins with an attractive woodcut lettering. This is the fourth edition published by Étienne Gueynard, following those of 1507, 1509 and 1515. A copy in a sober 17th-century binding. A few rare notes and reading notes are present in the margins, sometimes slightly trimmed by the binder. Binding skilfully restored, first white endpaper missing. Some foxing and wetness.
