Three important medieval manuscripts of the "Consolatio Philosophiae" (Harley 3095; Séléstat 93; Cracow, Berl. 939) were copied from the same archetype: either a late-ancient archetype or a good copy of one. It existed in Reichenau in the first half of the IX century and was taken by Irish monks to Liegi in the second half of the IX century, where Sedulius Scotus lived and taught. The manuscript belonged to the bishops of Liegi, who closely associated with Sedulius. At the end of the IX century, they had a copy made, which they inserted in the very recent commentary to the m. IX, b. III, written by Bovo of Corvey, together with another short anonymous commentary, a reply to Bovo. Quoting Macrobius, Bovo attacked Boethius and his Neoplatonic opinions, but the anonymous commentary defended him, showing with the help of Calcidius that such opinions are not Neoplatonic, but Platonic or Middle Platonic and not very far from the Catholic faith.
