ALBERT OF  AI% (fl. c . A.D . 1100), historian of the first crusade, was born during the later part of the rith century, and afterwards became canon and custos of the church of Aix-la-Chapelle . Nothing else is known of his life except that he was the author of a Historia Hierosolymitanae expeditions, or Chronicon Hierosolymitanum de bello sacra, a work in twelve books,written between 1125 and 1150 . This history begins at the time of the council of Clermont, deals with the fortunes of the first crusade and the earlier history of the Latin kingdom of Jerusalem, and ends somewhat abruptly in 1121 . It was well known during the middle ages, and was largely used by William, archbishop of Tyre, for the first six books of his Belli sacri historia . In modern times its historical value has been seriously impugned, but the verdict of the best scholarship seems to be that in general it forms a true record of the events of the first crusade, although containing some legendary matter . Albert never visited the Holy Land, but he appears to have had a considerable amount of intercourse with returned crusaders, and to have had access to valuable correspondence . The first edition of the history was published at Helmstadt in 1584, and a good edition is in the Recueil des historiens des croisades, tome iv . (Paris, 1841—1887) . See F .
