Largely on the basis of the works of the last three years of his life, van Gogh is generally considered one of the greatest Dutch painters of all time. His work exerted a powerful influence on the development of much modern painting, in particular on the works of the Fauve painters, Chaim Soutine, and the German Expressionists. Yet of the more than 800 oil paintings and 700 drawings that constitute his life’s work, he sold only one in his lifetime. Always desperately poor, he was sustained by his faith in the urgency of what he had to communicate and by the generosity of Theo, who believed in him implicitly. The letters that he wrote to Theo from 1872 onward, and to other friends, give such a vivid account of his aims and beliefs, his hopes and disappointments, and his fluctuating physical and mental state that they form a unique and touching biographical record that is also a great human document.
During the first days of his treatment, Van Gogh repeatedly and unsuccessfully asked for Gauguin, who asked a policeman attending the case to "be kind enough, Monsieur, to awaken this man with great care, and if he asks for me tell him I have left for Paris; the sight of me might prove fatal for him." Gauguin fled Arles, never to see Van Gogh again. They continued to correspond and in 1890 Gauguin proposed they form a studio in Antwerp. Meanwhile, other visitors to the hospital included Marie Ginoux and Roulin.
In despair of ever being able to overcome his loneliness or be cured, van Gogh shot himself. He did not die immediately. When found wounded in his bed, he allegedly said, “I shot myself.…I only hope I haven’t botched it.” That evening, when interrogated by the police, van Gogh refused to answer questions, saying, “What I have done is nobody else’s business. I am free to do what I like with my own body.”
By this time van Gogh was ready for such lessons, and the changes that his painting underwent in Paris between the spring of 1886 and February 1888 led to the creation of his personal idiom and style of brushwork. His palette at last became colourful, his vision less traditional, and his tonalities lighter, as may be seen in his first paintings of Montmartre. By the summer of 1887 he was painting in pure colours and using broken brushwork that is at times pointillistic. Finally, by the beginning of 1888, van Gogh’s Post-Impressionist style had crystallized, resulting in such masterpieces as Portrait of Père Tanguy and Self-Portrait in Front of the Easel, as well as in some landscapes of the Parisian suburbs.
