Psalter. | Defective at the beginning and at the end; it has lost many folios (see contents) and some bifolia are not in order (i.e. Ode 5 is followed by Ode 2:8d–40b; f. 337r follows f. 330v). The psalms are divided into καθίσματα and δόξαι. Titles and initials lettres are rubricated in gold. There is a marginal note in Latin on f. 334r by a 15th century English hand saying "Ego sum bonus”. It is followed by some letters of the Latin alphabet. According to James, this proves that the ms. was already in England during the Middle Ages (cf. James, The Western Manuscripts, III, p. 140). | Text-type: L.
