 Aside from these, thereafter there is no eyewitness to events in Jerusalem until William of Tyre, archbishop of Tyre and chancellor of Jerusalem, who began writing around 1167 and died around 1184, although he includes much information about the First Crusade and the intervening years from the death of Fulcher to his own time, drawn mainly from the writings of Albert of Aix and Fulcher himself.From the Muslim perspective, a chief source of information is Usamah ibn Munqidh, a soldier and frequent ambassador from Damascus to Jerusalem and Egypt, whose memoirs, "Kitab al i'tibar", include lively accounts of crusader society in the east.Further information can be gathered from travellers such as Benjamin of Tudela and Ibn Jubayr.
