This major study is a comprehensive scholarly work on a key moment in the history of Europe, the fall of Constantinople to the Ottoman Turks in 1453. The result of years of research, it presents all available sources along with critical evaluations of these narratives. The authors have consulted texts in all relevant languages, both those that remain only in manuscript and others that have been printed, often in careless and inferior editions. Attention is also given to 'folk history' as it evolved over centuries, producing prominent myths and folktales in Greek, medieval Russian, Italian, and Turkish folklore. Part I, The Pen, addresses the complex questions introduced by this myriad of original literature and secondary sources.

A member of the imperial Palaiologan family, albeit most probably illegitimate, Isidore became a scholar at a young age and began his rise in the Byzantine ecclesiastical ranks. He was an active advocate of the union of the Orthodox and Catholic Churches in Constantinople. His military exploits, including his participation in the defence of Constantinople in 1453, provide us with eyewitness accounts. Without doubt he travelled widely, perhaps more so than any other individual in the annals of Byzantine history: Greece, Asia Minor, Sicily, Russia, Poland, Lithuania, and Italy. His roles included diplomat, high ecclesiastic in both the Orthodox and Catholic churches, theologian, soldier, papal emissary to the Constantinopolitan court, delegate to the Council of Florence, advisor to the last Byzantine emperors, metropolitan of Kiev and all Russia, and member of the Vatican curia. This is an original work based on new archival research and the first monograph to study Cardinal Isidore in his many diverse roles. His contributions to the events of the first six decades of the quattrocento are important for the study of major Church councils and the fall of Constantinople to the Ottoman Turks. Isidore played a crucial role in each of these events.

Constantine XI's last moments in life, as he stood before the walls of Constantinople in 1453, have bestowed a heroic status on him. This book produces a more balanced portrait of an intriguing individual: the last emperor of Constantinople. To be sure, the last of the Greek Caesars was a fascinating figure, not so much because he was a great statesman, as he was not, and not because of his military prowess, as he was neither a notable tactician nor a soldier of exceptional merit. This monarch may have formulated grandiose plans but his hopes and ambitions were ultimately doomed, because he failed to inspire his own subjects, who did not rally to his cause. Constantine lacked the skills to create, restore, or maintain harmony in his troubled realm. In addition, he was ineffective on the diplomatic front, as he proved unable to stimulate Latin Christendom to mount an expedition and come to the aid of south-eastern Orthodox Europe. Yet in sharp contrast to his numerous shortcomings, his military defeats, and the various disappointments during his reign, posterity still fondly remembers the last Constantine.
