The Siege and the Fall of Constantinople in 1453 [PDF ebook] 
Historiography, Topography, and Military Studies

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.
