The Paris Psalter is an entire Anglo-Saxon psalm book written in both Latin and the West Saxon dialect of Old English. The manuscript dates from the middle of 11th century, written by a scribe who stated that he was called Wulfwinus cognomento Cada. The first 50 psalms are written in prose, while the Old English psalms from 51 to 150 are written in the metrical form. The first 50 psalms have been credibly attributed to Alfred the Great.
