Rationale divinorum officiorum. [With:] 15th-century Miscellaneous manuscripts including works by Jordanus de Quedlinburg and Thomas Aquinas.

Incunable Edition of Durand's Rationale. Bound with a late 15th-century manuscript miscellany.

An exceptionally clean copy of one of the most significant liturgical and theological writings of the 13th century, the Rationale divinorum officiorum by the French bishop and canon lawyer Guillaume Durand (c. 1230–1296).

This work is one of the most significant liturgical and theological writings of the 13th century, written by Guillaume Durand (c. 1230–1296), a French bishop and canon lawyer. The work provides a comprehensive symbolic and theological explanation of Christian liturgy, with the aim to present the deeper spiritual and allegorical meaning of church rituals, church architecture, vestments, holidays, and sacraments. Durand also adds theological and moral explanations to each liturgical element, helping priests and believers to participate in worship with greater awareness and deeper faith.

Complete, only the first blank leaf (A1) is missing. Gothic typography with approximately 47–48 lines per column, decorated with red and blue initials and red paragraph marks. Exceptionally clean paper.

Prov.: an early modern note referencing “Martini Lutheri Dr. – Incipiunt canones” (not Luther’s handwriting, but a reader’s note from the Reformation period), and a purchase entry from 1568: “Anno salutis 68 libellum istum emi 1568 in vigilia Pentecostes a quodam pistore Agrano nomine” (Purchased on Pentecost Eve 1568 from a baker named Agranus). Additional minor notes from the 16th century.

Bound together with three manuscripts of 15th century theological treatises:

Jordanus de Quedlinburg: Expositio orationis dominicae (almost complete, the last chapter is missing) and two minor works of Thomas Aquinas: the De articulis fidei et ecclesiae sacramentis (fragment, the first part only) and the In symbolum Apostolorum (complete), plus a briefly commented text of the Ten Commandments.

Latin manuscripts on paper, Gothic cursive (bastarda), two columns, rubricated, with red Lombard initials. [35] leaves. German territory, approx. 1450–1480.

While Thomas Aquinas needs no introduction, Jordanus de Quedlinburg (c. 1300–1380) was a distinguished Augustinian monk and 14th-century preacher, esteemed primarily for his homilies and religious instruction. Likely educated at the University of Prague, he gained prominence through his widely circulated sermon collections. Among his most significant works is the Expositio orationis dominicae, which offers a theological and moral exegesis of the prayer's individual components. The work aims to provide the faithful with a deeper understanding of the prayer's meaning and its practical application in daily Christian life. Jordanus elucidates the text using parables and moral lessons in a lucid style accessible to a lay audience.

Damaged, restored Gothic wooden board binding with brass fittings; clasps are missing.
