sentences:  After arriving with Bohemond's entourage at his return to Palestine (1107), Ralph took service with Bohemond's nephew Tancred, who ruled the principality of Antioch from 1108 to 1112.Though "Gesta Tancredi" depends to a great degree on eyewitness accounts, it was commenced after the death of Tancred (11 December 1112), supposedly in order to avoid possible charges of flattery by Ralph's patrons.Later historians have criticised his work as a panegyric of the Normans, especially his patrons, on crusade, but in fact the text has far more complex nuances.
