Psalter

Psalter. Most breviaries include a full Psalter or collection of the Psalms in order from 1 to 150. These may be enhanced with additional readings, prayers, and chants, such as here at the end of Psalm 39, which is followed by two antiphons, or sung prayers. The text of the Psalter is often embellished by a small illuminated initials, one for every verse. This decoration emphasizes the sanctity of the text, which although attributed to King David of the Old Testament, was considered to be a prefiguration of the New Testament.

A Ferial Psalter is organized so that all of the 150 psalms can be said in one week. The psalms are thus divided into sections at Psalms 1, 26, 38, 52, 68, 80, 97, and 109, with each section often marked by an illustration. With a limited number of leaves discovered from the Psalter, it is unclear whether or not the Llangattock Breviary was organized according to the ferial divisions. The leaves found thus far fall in between these, but there may be others comparable to the leaf with Psalm 26 from the Breviary of Ercole I d'Este, included here for comparison.
