GEORGE SPHRANTZES
The Ottoman Turks had captured Byzantium (Constantinople) in 1453. The Byzantines had received no help from their fellow Christians. The Christian Roman Empire was split in two—a Western (Latin) Empire led by the Roman Catholic Church in Rome, and the Eastern (Greek) Roman Empire led by the Orthodox Church headquartered in Constantinople (Byzantium). The two churches were not only in a theological conflict but violence broke out and the armies of the two religious empires attacked each other now and then. It was assumed that there would be mutual interest in protecting Europe from the Muslim armies. The comparison to the Sultan of Cairo was facetious of course. As a leading Muslim he would never provide any help to the Christians against other Muslims.
George Sphrantzes, also Phrantzes or Phrantza (Greek: Γεώργιος Σφραντζής or Φραντζής; 1401 – c. 1478), was a late Byzantine Greek historian and Imperial courtier. He was an attendant to Emperor Manuel II Palaiologos, protovestiarites ("Lord of the Imperial Wardrobe") under John VIII Palaiologos, and a close confidant to Constantine XI Palaiologos. He was an eyewitness of the Fall of Constantinople in 1453, made a slave by the victorious Turks, but ransomed shortly afterwards. Sphrantzes served the surviving members of the Palaiologian family for the next several years until taking monastic vows in 1472. It was while a monk he wrote his history, which ends with the notice of Sultan Mehmed II's attempt to capture Naupaktos, which he dates to the summer of 1477; Sphrantzes is assumed to have died not long after that event.
