Virgilio Diaz was made Chevalier of the Legion of Honour in 1851. Rousseau was left undecorated, but was nominated and awarded the Cross soon afterwards. He would eventually become an Officer of the Legion of Honor. At the Exposition Universelle of 1853, where all Rousseau's rejected pictures of the previous twenty years were gathered together, his works were acknowledged to form one of the best of the many splendid groups there exhibited. But, after an unsuccessful sale of his works by auction in 1861, he contemplated leaving Paris for Amsterdam or London, or even New York. Later years Rousseau then suffered a series of misfortunes. His wife's mental health had worsened; his aged father became dependent on him for pecuniary assistance; his patrons were few. Moreover, while he was temporarily absent with his ill wife, a youth living in his home (a friend of his family) committed suicide in his Barbizon cottage. When he visited the Alps in 1863, making sketches of Mont Blanc, he became dangerously ill with inflammation of the lungs; and when he returned to Barbizon he suffered from insomnia and became gradually weakened. He was elected president of the fine-art jury for the 1867 Exposition; however, his disappointment at being denied the better awards may have affected his health, for in August he became paralyzed. He recovered slightly, but was again attacked several times during the autumn. In November his condition worsened, and he died in the presence of his lifelong friend, Jean-François Millet, on December 22, 1867. Millet, the peasant painter, for whom Rousseau had the greatest regard, had been much with him during the last years of his life, and at his death Millet assumed charge of Rousseau's ill wife. Rousseau's other friend and neighbor, Jules Dupré, himself an eminent landscape painter of Barbizon, relates the difficulty Rousseau experienced in knowing when his picture was finished, and how he, Dupré, would sometimes take away from the studio some canvas on which Rousseau was laboring too long. Rousseau was a good friend to Diaz, teaching him how to paint trees, for until a certain point in his career Diaz considered he could only paint figures. Work Rousseau's pictures are always grave in character, with an air of exquisite melancholy. They are well finished when they profess to be completed pictures, but Rousseau spent so much time developing his subjects that his absolutely completed works are
