"This manuscript was illustrated in two different periods:Canterbury, c. 1200: 184 pages. This first section follows the iconographic cycle of the Utrecht Psalter. It opens with what Leroquais called the Psalter prologue, consisting of 8 extraordinary, full-page miniatures, and continues with 52 fascinating miniatures measuring approximately 15 x 32 cm (width of the page) at the beginning of each Psalm. Most pages feature decorated initials.Catalonia, c. 1340: from page 185 onwards we find 46 miniatures the width of the page and 15 to 25 cm high, surrounded by bright colours and divided into two or three bands each divided into two or three compartments. The few consisting of a single section appear on pages 328 and 340. The miniatures on pages 144, 146, 160, 162, 164 and 172 are also by Ferrer Bassa, although these are of a rather different style and may have been painted by the Catalan artist upon a sketch that the English artist left unfinished (judging by the composition, the iconography based on the Utrecht Psalter, and the stylistic and technical factors including drapes and the constant use of a royal blue that subsequently disappeared... the decorated letters on these folios are all by the English miniaturist). The folios from 185 onwards are characterised by the great iconographic freedom of the typological interpretation of both the Psalms and the New Testament prophecies." [from M.
