It is part of a medieval florilegium, now known as "Westminster Cathedral Treasury, MS 4", which was inscribed on parchment 1450-1500. The manuscript has '1368' written on the opening folio. Along with "Revelations of Divine Love", "Westminster Cathedral Treasury, MS 4" also contains commentaries on Psalms 90 and 91, purportedly by the 14th century Augustinian mystic Walter Hilton, and a compilation of Hilton's "The Scale of Perfection". During the 16th century it was owned by the Catholic Lowe family. In 1821, Bishop James Bramson made a hand calculation of the age of the manuscript on its endpaper. Rediscovered in August 1955, it is kept in the archives of Westminster Abbey, on loan from Westminster Cathedral.
