Before his death his pictures were so much valued that other artists tried to imitate them, and he was accustomed to keep a book of sketches by which his works could be proved. He called this book "Liber Veritatis," and before his death it reached six volumes; one of these containing two hundred drawings is at Chatsworth. A catalogue of his works describes more than four hundred landscapes. All the principal galleries of Europe have his pictures, and there are a great number of them in England, both in public and private collections. SEBASTIAN BOURDON (1616-1671), who was born at Montpelier, made his studies in Rome. He brought himself into notice by a picture of the Crucifixion of St Peter, which is now in the Louvre. He was one of the earliest members of the French Academy. Bourdon resided in Sweden for some years; but was in Paris, and held the position of Rector of the Academy when he died. He painted a few _genre_ subjects, and two of his portraits by himself are in the Louvre; but his best works were landscapes, and in these his style was like that of Salvator Rosa. It has been said that Rigaud assisted him in his portraits of himself. Bourdon made some engravings, and collectors prize his plates very much. There were other French painters who studied in Italy, but those that I have mentioned are the important ones. Of those who studied in their own country only, EUSTACHE LE SUEUR (1617-1655) was the first of any importance; but his life was short and uneventful, and he was not appreciated. His most important works are in the Louvre. CHARLES LE BRUN (1619-1690) was very prominent in his day. His father was a sculptor, and was employed by the Chancellor Segnier. This nobleman's attention was attracted to the son, and he at length sent the young Le Brun to Italy to study. He remained there six years, and after his return to Paris he was made painter to the king, and became the favorite of the court. He used his opportunities to persuade Louis XIV. to found the Royal Academy at Paris, which was done in 1648. All his principal pictures are in the Louvre. PIERRE MIGNARD (1612-1695) has been called "the Roman," because he lived in Rome twenty-two years, and while there was patronized by three successive popes. In 1664 he was made President of the Academy of St. Luke in Rome. At length Louis XIV. invited him to return to France. In 1690 he succeeded Le Brun as court painter, and was made Chancellor of the Academy. His portraits are his best works, and these are seen in the galleries of various European countries.
