The abbreviated Psalms commentary by Honorius Augustodunensis (ca. 1070 - ca. 1140)-a redaction of his own, much larger commentary on the entire Psalter-participates in a long tradition of Christian interpretation of the Book of Psalms. A prolific author closely associated with Anselm of Canterbury, Rupert of Deutz, and Gilbert of Poitiers, Honorius wrote a massive commentary on the Psalms when the so-called "school of Laon" was at work on the Glossa ordinaria. Honorius's work shares the academic interest of that school, while simultaneously serving the devotion of the Benedictine Reform. His Exposition of Selected Psalms highlights a tripartite division of the Psalter, even as it discovers in the psalms an apocalypticism fitting to the Church in its last age.
