The Codex Beneventanus (British Library, Add. MS 5463) is an 8th-century illuminated Gospel Book. According to a subscription on folio 239 verso, the manuscript was written by a monk named Lupus for one Ato, who was probably Ato, abbot the monastery St. Vincent on the Volturno, near Benevento. Ato was abbot from 736-760.
The codex contains the Vulgate version of the four Gospels, the canon tables of Eusebius of Caesarea, the letter of St. Jerome to Pope Damasus (Novum opus), the prologue of St. Jerome to the Gospels (Plures fuisse), and prologues and chapter lists for each of the Gospels. The text is written on vellum in two columns in Uncial script with no division between words. The running titles are in small uncials while the incipits and explicits are in capitals. The incipits and explicits are written in alternating lines of red and black ink. The subscription of Lupus is written in uncials, and also has alternating lines of red and black ink. The text contains additional punctuation and annotations in a 10th-century Beneventuan hand.
There are 240 folios of 355 by 275 mm. The folios are generally gathered into quires of eight folios each. There are a few gatherings of ten folios and a few gatherings are lacking one or more folios. The rear flyleaf (folio 240) is a piece of vellum from another manuscript and contains a fragment of a commentary on the Epistle to the Romans written in a 9th-century Carolingian minuscule that has 10th century Beneventan punctuation.
The manuscript has decorated canon tables, initials, and incipits and explicits. The canon tables are underneath arches decorated with gold, red and blue. Both sides of folio 4 have decorated arches, but are otherwise blank. Each of the Gospels begins with an initial which is decorated in green, red, and gold. The incipits and explicits are decorated with green red and black ivy leaves.
The manuscript was owned in the 8th century by the monastery of St. Vincent on the Voturno, and may have been produced there. By the 13th century it was associated with St. Peter's convent in Benevento. In the first half of the 18th century it was owned by Dr. Richard Mead, and was used by Dr. Richard Bentley in his collation of New Testament texts. Dr. Mead may have acquired the manuscript in the 1690s when he traveled to Italy, however, the manuscript did not appear in the catalog of the sale of his library in 1754-55. The manuscript was later owned by Anthony Askew (d. 1754). It was purchased by John Jackson in 1785 at the sale of Askew's manuscripts. The British Library purchased it in 1794 at the sale of Jackson's manuscripts.
