BOULLONGNE, 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 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.
