The exact origin and purpose of this manuscript is uncertain. It was begun in the 13th century, and added to in the 14th and 15th centuries. Most of its contents relate in some way to Ely Priory--many of them relating to a variety of private and public devotions--so it was presumably handed down from one Priory official to another. It appears to be a prayerbook, assembled for personal devotion. This initial introduces a prayer attributed to St Anselm of Canterbury (1033-1109), and shows Christ stepping out of his tomb at the Resurrection. It is within a devotional section entitled 'Little Book Which Is Called The Vision Of The Mind'. The prayer and picture within the initial are typical of devotional material which increased in popularity during the late middle ages as churchmen and laity desired greater personal access to God.
