(Robert), an English historian, of whom little more is known, than that he was keeper of the registry of the court of Canterbury in the reign of Edward III., and consequently that he lived in the 14th century. He wrote, Memorabilia gesta magnifici regis Anglie domini Edwardi tertii post conquisitum, procerumque; talibus primitivis quibusdam gestis de tempore patrii sui domini Eduardi secundi, que in regnis Angliae, Scotiae, et Franciae, ac in Aquitania et Britannia, non humana sed Dei potentia, contingant, per Robertum de Avesbury. This history ends with the battle of Poitiers, about the year 1356. It continued in manuscript till the year 1720, when it was printed by the industrious Thomas Hearne at Oxford, from a manuscript belonging to Sir Thomas Seabright. It is now become very scarce.
