The manuscript once belonged to Arsenius, Archbishop of Monembasia, in the Morea (as Lectionary 113), then to Gabriel, metropolitan of Philadelphia.
In 1345, Isidore, who was at the time the bishop elect of Monemvasia, and Gregory Palamas were excommunicated by a synod of anti-hesychast bishops that had been convened by Patriarch John XIV Kalekas who himself was an opponent of St. Gregory.
The work contains a history of the world from Creation until the early 17th century, and purports to have been written by a non-existent metropolitan of Monemvasia named Dorotheos.
The Byzantines raided and sacked the islands of Paros, Naxos, and Keos, as well as the towns of Karystos and Oreoi on Negroponte (Euboea), before sailing south to support the operations of an expeditionary force that landed at Monemvasia against the Principality of Achaea.
On 8 September (O.S.) 1822 the Turkish fleet, coming from Monemvasia, endeavoured to supply the town of Nafplion, which was at the time besieged by Greek forces since the spring of 1821.
