Guglielmo di Tiro: “Historia de la Guerra Sacra.” Venetia 1562 Second edition, in 4to 22x17cm, contemporary vellum, manuscript title vignette on spine, complete 8p.,[8]615p., very light scattered browning, overall very good. William of Tyre (1130-1186) was the principal chronicler of the medieval kingdom of Jerusalem. He achieved high positions in the administrative structure of the main Crusader state and traveled a lot around the Levant. His Historia contains several of his own travel accounts, as his two embassies to Constantinople through Anatolia, to meet Manuel Comnenus and discussed a Byzantine alliance, several visits in the other Crusader states and in Armenian Cilicia. He provides contemporary accounts for many buildings and places of the Byzantine capital, as well as of cities of Anatolia. Of particular importance is his description of the Greek society of his time (Luka Spoljaric: William of Tyre and the Byzantine Empire-Construction and deconstruction of an image, Budapest 2008). The first edition had been published in 1549 in Latin. A very precious source for the 12th century Levant. RARE
