The theological treatises of Gregory of Nazianzus (c. 329–389?) were hugely important for the Greek church in the Middle Ages, and they were widely copied. This manuscript contains a number of the sermons of Gregory, along with works by Pseudo-Dionysius the Areopagite and works attributed to the late antique author Nonnus. Written in a neat hand in two columns, the volume is filled with copious marginal annotations.

The manuscript has the distinction of being the oldest dated Greek manuscript in the British Library’s collections. A colophon indicates that it was completed in 972. It is a good example of the type of Greek manuscript produced by the Greek-speaking community in medieval Italy. It was purchased by the British Museum from one P. Rolandi in 1850.
