William of Tyre is, beyond all doubt, the most illustrious of the many historians who have written on the crusades. Born in Palestine, and though both educated for the church and raised step by step to its highest dignities, yet mingling continually in the political changes of the Holy Land--the preceptor of one of its kings--frequently employed in embassies to Europe, and ultimately Archbishop of Tyre and Chancellor of the kingdom of Jerusalem, William possessed the most extensive means of gathering materials for the great work he has left to posterity. He brought to his task, also, a powerful mind, as well as considerable discrimination; and was infinitely superior in education and every intellectual quality to the general chroniclers of his age. He was not born, however, at the time of the first crusade; and consequently, where he speaks of the events of that enterprise, we may look upon him as an historian, clear, talented, elegant, and not extremely credulous; but we must not expect to find the vivid identity of contemporaneous writing. In regard to the history of his own days he is invaluable, and in respect to that of the times which preceded them, his work is certainly superior, as a whole, to any thing that has since been written on the subject. A much more vivid and enthusiastic picture of the first crusade is to be found in Albert of Aix, from whom William of Tyre borrowed many of his details; but the Syrian Archbishop, living long after, saw the events he recounted as a whole, rejected much as false that Albert embraced as true, and softened the zealous fire which the passions and feelings of the moment had lighted up in the bosom of the other. Albert himself was not one of the crusaders; but living at the time, and conversing continually with those who returned from the Holy Land, he caught, to an extraordinary extent, the spirit of the enterprise, and has left behind him a brilliant transcript of all the passed-by dreams and long-extinguished enthusiasms of his day. Thus, as a painting of manners and customs, the _Chronicon Hierosolymitanum_ is one of the most valuable records we possess, and the account there given of Peter the Hermit and _Gautier sans avoir_ is in many points more full and comprehensive than any other. Fulcher of Chartres set out for the Holy Land with Stephen, Count of Blois, one of the first crusaders. He soon after became chaplain to Baldwin, the brother of Godfrey de Bouillon, and ended his days a canon of the Holy Sepulchre. His relation is useful in many respects, especially in regard to the march of the crusaders through Italy--the proceedings of Baldwin at Edessa, and the history of Jerusalem for several years after its conquest. His style, however, is tumid and circumlocutory, and his credulity equal to that of Raimond d'Agiles.
