Heraldry on the first page of the Psalms text strongly suggests that this Psalter was commissioned by King Edward I for the marriage of his son Alphonso, to Margaret, daughter of Florent V, Count of Holland, which was to take place in 1284. Alphonso died before the wedding, however, and the decoration of the manuscript was left incomplete. Additions were made in the early 14th century, probably before 1316. Luxury books such as this often begin with a series of large miniatures of the life of Christ. This manuscript did not, when it was first created, so a later owner has added a series of miniatures cut from another book, perhaps acquired second-hand. These six small scenes were cut from a late 13th-century manuscript, probably a Book of Hours or Psalter made in France, and pasted into the present manuscript in England in the early 14th century. They show the Descent from the Cross, Entombment, Harrowing of Hell, Resurrection, Maries at the Sepulchre, and 'Noli Me Tangere'.
