This psalter was made in Ireland (Armagh?), probably in the late 12th century to judge from the style of the script. The scribe signed his name on one of its pages: 'Cormacus wrote this psalter: pray for him'. Its decoration shares some features of manuscripts from Armagh, but it combines stylistic elements seen in 8th- and 9th-century illumination (in masterpieces such as the Book of Kells) with current styles. Containing canticles or verse passages from the Bible, such as Deut. 32:1-43, as well as the Book of Psalms, it was used as a prayerbook or hymnal in church services. Psalm 92, like all the others in this manuscript, begins with a large initial decorated with animal heads and fine interlace, although it is somewhat simpler than many of the others. The page also is less embellished than others closer to the beginning of the book. It still has coloured letters which indicate the beginnings of verses, but there are no 'line fillers' or decorative calligraphic strokes to fill in short lines to enliven it, and there is no title in colourful letters.
