Among its late medieval holdings the Bodleian Library preserves a small fifteenth-century Latin devotional prayer book, Oxford, Bodleian Library MS Lat. liturg. f. 9 (Summary Catalogue 31537), which contains, on the recto of fol. 17, a series of short (or abbreviated) Latin prayers long thought to have been by Catherine of Valois (1401-1437), queen of King Henry V (1387-1422).l The manuscript, on parchment, measures blA x 4lA inches (14 x 10.2 cm.) and now contains 145 leaves. Its capitals are decorated throughout, and it contains as well nine large decorated capitals (fols. 37r, 39r, 41r, 42r, 43r, 44r, 45r, 47r, 53r), and two historiated initials, one showing Christ's Cross suspending a green wreath at the intersection of its crossbar (fol. 60r), the other a blue, orange, and gold floral design (fol. 79r), but any full-page miniatures have been excised from this now imperfect manuscript. Its present binding is of modern purple velvet with a silver cartouche reading Preces Privatie Saec. XV. attached to the center of the top board. Both the binding and the cartouche predate Bodley's acquisition of the manuscript, by private treaty from Miss R. Ryder (fol. lv), on December 7, 1893. As its catalogue description reports, the manuscript may have been for a lady named Catherine, the name whose Latin form appears on fols. 84r, 86r, 90v, and 114r. The Latin calendar (which lacks three leaves) is English, and the tables that follow it cover the years 1406-1462, suggesting a date for the manuscript, or more probably for its exemplar, of about 1406. E. W. B. Nicholson, who catalogued the manuscript in the Summary Catalogue, divided it into three parts: part A: fols. 3r-78v; part B: fols. 79r-122v; and part C: fols. 123r-143v, which ends imperfectly. Nicholson reasonably believed the third part to have been written and illuminated like and like it, copied from a Sarum book of hours. Part A, he confidently believed,
