This manuscript is made out of two parts (part 1: ff. 1-167; part
2: ff. 168-248) that were produced separately at the Benedictine
abbey of Stavelot (Wallonia) in the last quarter of the 12 th
century and were joined there as well. The resulting manuscript
contains complete copies of De Institutis Coenobiorum (On the
Institutes of Cenobitic Monks) and Collationes Sanctorum Patrum
(Conferences of the Desert Fathers), works about the monastic life,
by John Cassian (b. c. 360, d. 435). The manuscript also contains
one of the earliest extant copies of the office for the feast of St
Thomas Becket (d. 1170) that were composed at Christ Church in
Canterbury, where Becket’s feast was celebrated for the first
time in 1173. Stavelot’s access to the office shortly after its
composition suggests that there was active textual transmission
between the Continent and England at this time. Contents:f. 1v: A
commentary on John Cassian by Gennadius of Marseille (d. c. 496),
beginning ‘Gennadius in libro de viris illustribus’. f. 1v: A
