Historia Rerum in Partibus Transmarinis Gestarum -Language: latin

William of Tyre (c. 1130 - September 29, 1186), was a medieval prelate and chronicler.As archbishop of Tyre he wrote the Latin chronicle between 1170 and 1184. It contains twenty-three books; the final book, which deals with the events of 1183 and the beginning of 1184, has only a prologue and one chapter, so it is either unfinished or the rest of the pages were lost before the whole chronicle began to be copied. William had access to the chronicles of the First Crusade, including Fulcher of Chartres, Albert of Aix, Raymond of Aguilers, Baldric of Dol, and the Gesta Francorum, as well as other documents located in the kingdom's archives. He used Walter the Chancellor and other now-lost works for the history of the Principality of Antioch. From the end of Fulcher's chronicle in 1127, William is the only source of information from an author living in Jerusalem. As the Dictionary of the Middle Ages says, "William's achievements in assembling and evaluating sources, and in writing in excellent and original Latin a critical and judicious (if chronologically faulty) narrative, make him an outstanding historian, superior by medieval, and not inferior by modern, standards of scholarship." www.arepo.biz
