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 9 begins in the lower half of the page, its first letter C(onfitebor, 'I will praise') a strange interlace animal which combines late 12th-century styles with early 9th-century designs of animal heads. Another bizarre animal stand below the last line on the page, mimicking the word 'throne' ('sedes s[upe]r thronu[m]': 'you have sat on your throne') and at the same time serving as a run-over mark to guide the reader to the last letters.
