Gallican Psalter with interlinear Old English gloss.
- s. xi3/4
Psalter thought to have been produced in Ireland in the early 10th century. It suffered in the fire at Ashburnham House in 1731, although important work was undertaken in the 19th century to salvage the burnt leaves. An Irish colophon, now lost but known through a transcript by James Ussher, includes a prayer for one Muiredach, who has been identified with the Muiredach mac Domnaill who was abbot of Mainistir Buite (Monasterboice) and died in 923.

They represent unique copies, less likely originals, of sketches that were made by Edward Lhuyd, or one of his assistants and correspondents, during his journeys through Britain and Ireland c.1700. The collection was made for the antiquarian John Anstis. Also included is a letter from Richard Richardson to Edward Lhuyd, dated 3 July 1709 (i.e. shortly after the recipient's death).
