This article provides a thorough survey of the sources of Hrabanus Maurus'
De rerum naturis, book VI: Isidore of Seville,
Etymologies and
De fide catholica contra Iudaeos, the
Clavis pseudo-Melitonis and Eucherius of Lyons'
Formulae spiritalis intelligentiae, the Bible, Jerome's
in Isaiam, Cassiodorus,
Expositio Psalmorum, Gregory the Great,
Homiliae in Hiezechielem prophetam,
Regula pastoralis, and
Moralia in Iob, Bede,
De tabernaculo,
De templo Salomonis, Ambrose Autpert,
Sermo in purificatione sanctae Mariae, Alcuin,
Compendium in Canticum canticorum, among others. A detailed commentary on the way Hrabanus rearranged the material he used is given. In some cases, it is possible to figure out the line of the textual transmission of the source of Hrabanus. For instance, the A. shows that the exemplar of the
Etymologies used by Hrabanus Maurus must have been very similar to Y (Valenciennes, BM, 399 [382]), a manuscript of Saint-Amand copied in the early ninth-century in the time of Arn. As for the
Clavis pseudo-Melitonis and Eucherius of Lyons'
Formulae spiritalis intelligentiae, the A. suggests that Hrabanus did not use them directly, but through an intermediary source. The exemplar of Casssiodorus'
Expositio Psalmorum used by Hrabanus belonged to the Germanic branch beta. The complete list of sources is given at the end.
