Guiliam or Willem Backereel (1570 in Antwerp - 10 August 1626 in Rome), was a Flemish Baroque landscape painter.
According to Houbraken, who repeated the information from Joachim von Sandrart's Teutsche Academie, Willem Backereel was from a large painting family that always had a few brothers in Rome. Willem's brother Gillis Backereel lived with him in Rome, but returned to Antwerp, where he later died. Both brothers were known as landscape painters.[1]
According to the RKD he was in Italy from 1605 onwards and was taught painting by his older brother Gillis.[2] His Roman sketches of the Flavian Palace are similar to works by Cornelis van Poelenburch, Jan Asselijn and Jacob de Heusch.
