Severely damaged in a fire in 1731, this psalter was part of the collection of Robert Cotton which eventually became part of the British Library. It was made in Ireland, although where is not known for certain. An inscription, now lost, was supposed to have connected it to a person called Muiredach. The most well-known Muiredach was abbot of Monasterboice in the early 10th century, and usually the psalter's origin is placed there for that reason. Also, some of the decoration in it resembles carvings on the stone Cross of Muiredach at Monasterboice. Each page has some type of animal decoration. Here, on the page with Psalms 82-85 an animal with long dangling legs forms the letter q. Its body is entangled in interlace that ends in a leaf. It resembles some of the initials in the earlier Book of Kells but it is more elongated, in the later style of decoration.
