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.
