[1] It is held in the John Rylands Library in Manchester, and is sometimes called the "Crawford MS" because it is so inscribed on the backstrip after having previously been in the library of the oriental manuscript collector Alexander Lindsay, 25th Earl of Crawford the Earl of Crawford and Balcarres.
[2] The library was sold by the 26th Earl of Crawford to Enriqueta Rylands in 1901, and there are other manuscripts from the Earl's collection at John Rylands also called Crawford manuscripts, including the "Crawford Codex" a Latin translation of the Almagest from Arabic by Gerhard of Cremona.
[3] The Irish Syriacist John Gwynn having compiled an edition of the Catholic Epistles, also missing from the Peshitta from 20 manuscripts, (1893) used this single manuscript to supply the missing Book of Revelation (1897).
[4] Gwynn considered that this Aramaic Revelation was not from the original Peshitta version but one which Gwynn identified as being from what he called the Philoxenian Version, an Aramaic revision of the Syriac Bible made under the auspices of Philoxenus, bishop of Mabbug circa 507.
[5] Basing his opinion on the testimony of Moses of Aghel, Gwynn considered that Philoxenus' chorepiscopus Polycarpus made a new translation from the Greek New Testament of the missing books.
