(Bon de), a painter of some eminence, was born at Paris in 1649. From his father Louis de Boulogne he learned the first principles of the art; but went to Rome in order to perfect himself from the works of the best masters. He abode in Italy five years. He excelled in history and portrait. His talents for copying the pictures of the great Italian painters were so very extraordinary, that he frequently deceived the greatest judges. He died at Paris in 1717, aged 68.

(Louis de), born at Paris in 1654, was the younger brother of the preceding; and like him learned from his father the first principles of painting, and afterwards went to Rome to complete his studies. His works, on his return, were so much esteemed, that Louis XIV. honoured him with the Boulogne order of St Michael, and, after the death of Antony Coypell, appointed him his principal painter. He chiefly excelled in historical and allegorical subjects. He died at Paris in 1734, aged 80 years.
