medieval monk and chronicler whose works, though lacking critical sense and order, are useful as historical documents. He read extensively, traveled considerably, and observed and recorded major events.

Some accounts portray him as an unruly character and a wanderer. He traveled among monasteries, stopping at each to study or work. After working for a time under Abbot Helderic at Saint-Germain in Auxerre, Glaber lived at Moutiers-St. Jean between 1005 and 1010. He then stayed at Saint-Bénigne under Abbot William of Volpiano, whose life he recounted in Vita Guillelmi. The five books of his Historiae, written at Cluny from 1030 to 1035, were dedicated to Odilo, abbot of Cluny. Glaber later returned to Saint-Germain.
