Critical edition of the commentary by Angelomo of Luxeuil, a work that probably dates back to the second half of the year 851. The Opusculum was commissioned by Emperor Lothair after the death of his consort Ermengard and was probably finished by the Advent of the same year. For its composition, Angelomo made use of three main sources: the exegesis to the Canticle by Apponius, that by Gregory the Great and the compilation Vox antique ecclesie.
