Aegidius Leodiensis, or Giles of Liege, a monk of the Vallde d' Or, a monastery of the Order of Citeaux. in the duchy of Luxemburg, lived in the early part of the 13th century. He wrote a history of the bishops of Liege, from the time of Theodwin, successor of Wason, to Henry III, sixty-ninth bishop. This history (Gesta Episcoporum Leodiensiuns), to the. year 1246, has been continued to 1348 by John Zlocsemius, canon of St. Lambert of Liege. John Chapeaville published it, with other chronicles, at Liege in 1613. The life of St. Albert, taken from his work, has been translated into Spanish, and published under the title Vida de S. Alberto, Cardinal del Titulo de Santa-Cruz, Obispo de Lieja y Martyr, trad. en Castellano por Andres de Soto (Brusellas,'1613). See Hoefer, Nouv. Biog. Generale, s.v.
