Between February and April 1890 Van Gogh suffered a severe relapse. Depressed and unable to bring himself to write, he was still able to paint and draw a little during this time, and he later wrote to Theo that he had made a few small canvases "from memory ... reminisces of the North". Among these was Two Peasant Women Digging in a Snow-Covered Field at Sunset. Hulsker believes that this small group of paintings formed the nucleus of many drawings and study sheets depicting landscapes and figures that Van Gogh worked on during this time. He comments that this short period was the only time that Van Gogh's illness had a significant effect on his work. Van Gogh asked his mother and his brother to send him drawings and rough work he had done in the early 1880s so he could work on new paintings from his old sketches. Belonging to this period is Sorrowing Old Man ("At Eternity's Gate"), a colour study Hulsker describes as "another unmistakable remembrance of times long past". His late paintings show an artist at the height of his abilities, according to the art critic Robert Hughes, "longing for concision and grace".
Many of the comedy films Van Dyke starred in throughout the 1960s were relatively unsuccessful at the box office, including What a Way to Go! with Shirley MacLaine, Lt. Robin Crusoe, U.S.N., Fitzwilly, The Art of Love with James Garner and Elke Sommer, Some Kind of a Nut, Never a Dull Moment with Edward G. Robinson, and Divorce American Style with Debbie Reynolds and Jean Simmons. But he also starred as Caractacus Pott (with his native accent, at his own insistence, despite the English setting) in the successful musical version of Ian Fleming's Chitty Chitty Bang Bang (1968), which co-starred Sally Ann Howes and featured the same songwriters (The Sherman Brothers) and choreographers (Marc Breaux and Dee Dee Wood) as Mary Poppins.
Van Gogh learned about Fernand Cormon's atelier from Theo. He worked at the studio in April and May 1886, where he frequented the circle of the Australian artist John Peter Russell, who painted his portrait in 1886. Van Gogh also met fellow students Émile Bernard, Louis Anquetin and Henri de Toulouse-Lautrec – who painted a portrait of him in pastel. They met at Julien "Père" Tanguy's paint shop, (which was, at that time, the only place where Paul Cézanne's paintings were displayed). In 1886, two large exhibitions were staged there, showing Pointillism and Neo-impressionism for the first time, and bringing attention to Georges Seurat and Paul Signac. Theo kept a stock of Impressionist paintings in his gallery on boulevard Montmartre, but Van Gogh was slow to acknowledge the new developments in art.
Van Gogh drew, and painted with watercolours while at school, but only a few examples survive and the authorship of some has been challenged. When he took up art as an adult, he began at an elementary level. In early 1882, his uncle, Cornelis Marinus, owner of a well-known gallery of contemporary art in Amsterdam, asked for drawings of The Hague. Van Gogh's work did not live up to expectations. Marinus offered a second commission, specifying the subject matter in detail, but was again disappointed with the result. Van Gogh persevered; he experimented with lighting in his studio using variable shutters, and with different drawing materials. For more than a year he worked on single figures – highly elaborate studies in black and white,[note 11] which at the time gained him only criticism. Later, they were recognised as early masterpieces.
Van Gogh returned home a fortnight later and resumed painting, producing a mirror-image Self-Portrait with Bandaged Ear and Pipe, several still lifes, and La Berceuse (Woman Rocking a Cradle; Augustine-Alix Pellicot Roulin, 1851–1930). Several weeks later, he again showed symptoms of mental disturbance severe enough to cause him to be sent back to the hospital. At the end of April 1889, fearful of losing his renewed capacity for work, which he regarded as a guarantee of his sanity, he asked to be temporarily shut up in the asylum at Saint-Rémy-de-Provence in order to be under medical supervision.
Ill from drink and suffering from smoker's cough, in February 1888 Van Gogh sought refuge in Arles. He seems to have moved with thoughts of founding an art colony. The Danish artist Christian Mourier-Petersen became his companion for two months, and at first Arles appeared exotic. In a letter, he described it as a foreign country: "The Zouaves, the brothels, the adorable little Arlésienne going to her First Communion, the priest in his surplice, who looks like a dangerous rhinoceros, the people drinking absinthe, all seem to me creatures from another world."
Limited access to life outside the clinic resulted in a shortage of subject matter. Van Gogh instead worked on interpretations of other artist's paintings, such as Millet's The Sower and Noonday Rest, and variations on his own earlier work. Van Gogh was an admirer of the Realism of Jules Breton, Gustave Courbet and Millet, and he compared his copies to a musician's interpreting Beethoven.
He wrote that they represented his "sadness and extreme loneliness", and that the "canvases will tell you what I cannot say in words, that is, how healthy and invigorating I find the countryside". Wheatfield with Crows, although not his last oil work, is from July 1890 and Hulsker discusses it as being associated with "melancholy and extreme loneliness". Hulsker identifies seven oil paintings from Auvers that follow the completion of Wheatfield with Crows.
Van Gogh suffered from psychotic episodes and delusions and though he worried about his mental stability, he often neglected his physical health, did not eat properly and drank heavily. His friendship with Gauguin ended after a confrontation with a razor when, in a rage, he severed part of his own left ear. He spent time in psychiatric hospitals, including a period at Saint-Rémy. After he discharged himself and moved to the Auberge Ravoux in Auvers-sur-Oise near Paris, he came under the care of the homeopathic doctor Paul Gachet. His depression continued and on 27 July 1890, Van Gogh shot himself in the chest with a revolver. He died from his injuries two days later.
