Guillaume Caoursin, the Vice-chancellor of the Order of the Hospital, wrote the Obsidionis Rhodiae urbis descriptio (Description of the Siege of Rhodes) as the official record of the Ottoman siege of the Knights in Rhodes in 1480.

Two other published eyewitness accounts, Pierre D Aubusson s Relatio obsidionis Rhodie and Jacomo Curte s De urbis Rhodiae obsidione a. 1480 a Turcis tentata, also appear in modern Latin edition and English translation. This book also includes John Kay s Description of the Siege of Rhodes and an English translation of Ademar Dupuis Le siege de Rhodes. The lengthy introductory chapters by Theresa Vann place the Ottoman siege of Rhodes in 1480 within the context of Mehmed II s expansion in the Eastern Mediterranean after he captured Constantinople in 1453. They then examine the development of an official message, or propaganda, as an essential tool for the Hospitallers to raise money in Europe to defend Rhodes, a process that is traced through the chancery s official communications describing the aftermath of Constantinople and the Ottoman"
