 The theological treatises were probably already known by the pupils of Alcuin at the court of Charlemagne around 800, and a tradition of glosses to the text probably goes back to the School of Auxerre in the later ninth century. The opuscula sacra provided a model for early medieval thinkers who wanted to use their logical training in thinking about Christian doctrine. Anselm was certainly aware of them, though he looked more closely to Augustine; Abelard’s first theological work, the Theologia Summi Boni, despite its originality, is clearly inspired by Boethius’s first treatise (on the Trinity). In the 1140s, Gilbert of Poitiers expounded his metaphysics and his view of theology in a detailed exegesis of the opuscula sacra, which came to be the standard commentary, although the treatises were also commented on by other, more Platonically-minded twelfth-century scholars. Although the opuscula sacra were not formally a part of the theology curriculum in most later medieval universities, they continued to be studied, and Aquinas wrote commentaries on Treatises I and III.
