Pierre Bersuire; Adam Petri, Brother of Peter Berthori of Picta, of the Order of the Holy Father Benedict, *Morale reductoriu[m] super tota[m]…*

Pierre Bersuire’s *Morale reductorium super totam Bibliam* served for centuries in monasteries and universities as an aid to exegesis, preaching, and teaching. Adam Petri’s 1515 Basel edition is considered a classic of early printed theological literature.

A copy in period binding—leather over boards, without a spine; endpapers from a parchment manuscript, reused by the bookbinder. The title page and the following page show tears and missing sections, a crossed-out annotation, and a smudged signature. Significant water damage across nearly the entire block (except for folios 80–89); localized paper rot in the final sections; on folios 3–19, purple stains at the level of the water damage. There is a smudged signature on the last page. Despite significant damage, the copy is preserved in its entirety, and the text is generally legible.
