"Life of Gregory the Great," by Johannes Diaconus, lib. ii. cap. 37.
The words are, "quæ omnia illustrantur Romano habitu, figuris, et antiquitate. Imperatoris Valentiniani tempora videntur attingere." This mistake of the old librarian has been corrected with much care and learning by the Baron van Tiellandt.—See his "Naspeuringen nopens zekeren Codex Psalmorum in de Utrechtsche Boekerij berustende, door W. H. J. Baron van Westreeinen van Tiellandt."
The MS. department of the British Museum possesses some tracings from the Utrecht Psalter, and on confronting them with the Harleian 603, it requires a sharp eye to detect the slight differences existing between several of the illustrations to each of the volumes. In the Harleian volume, all the subjects have not been filled in; some are left out altogether, spaces being reserved for them in the text, and others are faintly traced with a leaden or silver point, preparatory to inking in: very few artists of the present day could block in the general forms in so peculiar a style with greater freedom or more complete conveyance of expression, by similarly slight indications.
The whole of the illuminations are given in the twenty-fourth volume of the "Archæologia." The manuscript stands in the Bodleian Catalogue, "Junius, No. II."
