ALBERT OF AIX (fl. c. A.D. IIOo), historian of the first crusade, was canon and custos of the church of Aix-la-Chapelle. He wrote a Historia Hierosolymitanae expeditionis or Chronicon Hierosolymitanum de bello sacro, a work in 12 books, between 1125 and 1150. This book gives the history of the first crusade and of the Latin Kingdom of Jerusalem down to 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. 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, 1841-87)• See M.
