The manuscript is an English Psalter that was created in the early 15th century. This manuscript is also Brigittine, meaning that it relates to that order of monks and nuns. It was therefore probably made for Syon, this being the only Brigittine foundation in England.
The Kalendar starts on f.1r.
Entries in the Kalendar that suggest and English and Brigittine origin are as follows. 7 May: Saint John of Beverley, cum regimine chori (in red, with his Translation, 25 October, in black); 28 May: Translation of Saint Bridget, Majus Duplex; 23 July: Birth of Saint Bridget, Majus Duplex; 13 July: Saint Mildred.
Other significant entries are as follows. 28 February: Saint Oswald, Bishop of Worcester and York; 30 April: Saint Erkenwald, ix lc; 11 May: Saint Fremud; 10 May: Saint Brendan, Abbot; 4 September: Translation of Saint Cuthbert, ix lc.
The Psalter starts on f.7r. It is missing Psalms 24:14-Psalms 25:4; Psalms 50:9-Psalms 52:4; and Psalms 79:19-end of Psalms 81lxxxi.
The Canticles and Quicunque vult start on f.112r.
The hand is Gothic, fairly written. The ornament consists of plain red and blue verse initials; blue and red filigree Psalm initials, and floriated initials, blue and lake on burnished gold grounds, at the divisions of the Psalter.
The initial to Beatus vir (f.7r) has a full border consisting of two narrow bands of gold and colour with circular bosses at each corner and feathery branch work with foliage and gold balls. The others have partial borders of similar design (for example f.30r, f.80v, f.92r). Probably four of the floriated initials are missing.
