This three-volume edition in Greek with Latin translation of the History by Nicephorus Gregoras (c. 1295â1360) was edited by Ludwig Schopen (Volumes 1 and 2 1829â30) and Immanuel Bekker (Volume 3 1855). The astronomer and historian Gregpras became the archivist of the Byzantine Emperor Andronikos II Palaiologos (to whom he proposed a calendar reform similar to that adopted by Pope Gregory XIII in 1582) and was involved in the fruitless negotiations of 1333 to unite the Greek and Latin Churches. The thirty-seven books of Gregoras' History overlap with the work by George Pachymeres and continue the narrative to 1359. This period is also covered in the History by the ex-Emperor John Cantacuzene and both these authors are also reissued in this series. Volume 3 describes the overthrow of John VI his withdrawal to a monastery and the accession of John V Palaiologos the son of Andronikos III. Language: English
