The psalter in CCCC MS 468, dating to c. 1250, has parallel Latin-Greek text, although the Greek is written in Latin script. It contains a calendar of the Benedictine Abbey of Ramsey and probably belonged to the prior, Gregory of Huntingdon (fl. c. 1290). On the front flyleaf are the cipher characters of a Greek system of numbers brought back from Greece by John of Basingstoke, archdeacon of Leicester (d. 1252). The book also contains a section of verses concerned with prognostics, proverbs and the world of nature.
