The time in Arles became one of Van Gogh's more prolific periods: he completed 200 paintings, and more than 100 drawings and watercolours.[115] He was enchanted by the local landscape and light; his works from this period are rich in yellow, ultramarine and mauve. His paintings include harvests, wheat fields and general rural landmarks from the area, including The Old Mill (1888), a picturesque structure bordering the wheat fields.[116] This was one of seven canvases sent to Pont-Aven on 4 October 1888 in an exchange of works with Paul Gauguin, Émile Bernard, Charles Laval and others.[116]

Van Gogh was a serious and thoughtful child.[25] He was taught at home by his mother and a governess, and in 1860 was sent to the village school. In 1864 he was placed in a boarding school at Zevenbergen,[26] where he felt abandoned, and campaigned to come home. Instead, in 1866 his parents sent him to the middle school in Tilburg, where he was deeply unhappy.[27] His interest in art began at a young age. He was encouraged to draw as a child by his mother,[28] and his early drawings are expressive,[26] but do not approach the intensity of his later work.[29] Constant Cornelis Huijsmans, who had been a successful artist in Paris, taught the students at Tilburg. His philosophy was to reject technique in favour of capturing the impressions of things, particularly nature or common objects. Van Gogh's profound unhappiness seems to have overshadowed the lessons, which had little effect.[30] In March 1868 he abruptly returned home. He later wrote that his youth was "austere and cold, and sterile".[31]
What particularly struck me when I saw the old Dutch paintings again is that they were usually painted quickly. That these great masters like Hals, Rembrandt, Ruisdael – so many others – as far as possible just put it straight down – and didn't come back to it so very much. And – this, too, please – that if it worked, they left it alone. Above all I admired hands by Rembrandt and Hals – hands that lived, but were not finished in the sense that people want to enforce nowadays ... In the winter I'm going to explore various things regarding manner that I noticed in the old paintings. I saw a great deal that I needed. But this above all things – what they call – dashing off – you see that's what the old Dutch painters did famously. That – dashing off – with a few brushstrokes, they won't hear of it now  – but how true the results are.
Van Gogh strove to be a painter of rural life and nature,[212] and during his first summer in Arles he used his new palette to paint landscapes and traditional rural life.[213] His belief that a power existed behind the natural led him to try to capture a sense of that power, or the essence of nature in his art, sometimes through the use of symbols.[214] His renditions of the sower, at first copied from Jean-François Millet, reflect Van Gogh's religious beliefs: the sower as Christ sowing life beneath the hot sun.[215] These were themes and motifs he returned to often to rework and develop.[216] His paintings of flowers are filled with symbolism, but rather than use traditional Christian iconography he made up his own, where life is lived under the sun and work is an allegory of life.[217] In Arles, having gained confidence after painting spring blossoms and learning to capture bright sunlight, he was ready to paint The Sower.[208]
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.
After his recovery, and despite his antipathy towards academic teaching, he took the higher-level admission exams at the Academy of Fine Arts in Antwerp, and in January 1886 matriculated in painting and drawing. He became ill and run down by overwork, poor diet and excessive smoking.[99] He started to attend drawing classes after plaster models at the Antwerp Academy on 18 January 1886. He quickly got into trouble with Charles Verlat, the director of the Academy and teacher of a painting class, because of his unconventional painting style. Van Gogh had also clashed with the instructor of the drawing class Franz Vinck. Van Gogh finally started to attend the drawing classes after antique plaster models given by Eugène Siberdt. Soon Siberdt and Van Gogh came into conflict when the latter did not comply with Siberdt's requirement that drawings express the contour and concentrate on the line. When Van Gogh was required to draw the Venus of Milo during a drawing class, he produced the limbless, naked torso of a Flemish peasant woman. Siberdt regarded this as defiance against his artistic guidance and made corrections to Van Gogh's drawing with his crayon so vigorously that he tore the paper. Van Gogh then flew into a violent rage and shouted at Siberdt: 'You clearly do not know what a young woman is like, God damn it! A woman must have hips, buttocks, a pelvis in which she can carry a baby!' According to some accounts this was the last time Van Gogh attended classes at the Academy and he left later for Paris.[100] On 31 March 1886, which was about a month after the confrontation with Siberdt, the teachers of the Academy decided that 17 students, including Van Gogh, had to repeat a year. The story that Van Gogh was expelled from the Academy by Siberdt is therefore unfounded.[101]
Because the most sensational events of van Gogh’s life—the conflicts with Gauguin, the mutilation of his left ear, and the suicide—are thinly documented and layered with apocrypha and anecdote, there is a trend in van Gogh studies to penetrate the layers of myth by reconstructing the known facts of the artist’s life. This scholarly analysis has taken many forms. Medical and psychological experts have examined contemporary descriptions of his symptoms and their prescribed treatments in an attempt to diagnose van Gogh’s condition (theories suggest epilepsy, schizophrenia, or both). Other scholars have studied evidence of his interaction with colleagues, neighbours, and relatives and have meticulously examined the sites where van Gogh worked and the locales where he lived. In light of van Gogh’s continually increasing popularity, scholars have even deconstructed the mythologizing process itself. These investigations shed greater light on the artist and his art and also offer further proof that, more than a century after his death, van Gogh’s extraordinary appeal continues to endure and expand.
Van Gogh's works are among the world's most expensive paintings. Those sold for over US$100 million (today's equivalent) include Portrait of Dr Gachet,[286] Portrait of Joseph Roulin and Irises. The Metropolitan Museum of Art's version of Wheat Field with Cypresses was acquired in 1993 for US$57 million.[287] In 2015 L'Allée des Alyscamps sold for US$66.3 million at Sotheby's, New York, exceeding its reserve of US$40 million.[288] 

There was interest from a dealer in Paris early in 1885.[86] Theo asked Vincent if he had paintings ready to exhibit.[87] In May, Van Gogh responded with his first major work, The Potato Eaters, and a series of "peasant character studies" which were the culmination of several years of work.[88] When he complained that Theo was not making enough effort to sell his paintings in Paris, his brother responded that they were too dark, and not in keeping with the bright style of Impressionism.[85] In August his work was publicly exhibited for the first time, in the shop windows of the dealer Leurs in The Hague. One of his young peasant sitters became pregnant in September 1885; Van Gogh was accused of forcing himself upon her, and the village priest forbade parishioners to model for him.[89]

Van Gogh made several painting excursions during visits to the landscape around Arles. He made paintings of harvests, wheat fields and other rural landmarks of the area, including The Old Mill (1888); a good example of a picturesque structure bordering the wheat fields beyond.[116] At various points, Van Gogh painted the view from his window – at The Hague, Antwerp, and Paris. These works culminated in The Wheat Field series, which depicted the view from his cells in the asylum at Saint-Rémy.[256]
The name of van Gogh was virtually unknown when he killed himself: only one article about him had appeared during his lifetime. He had exhibited a few canvases at the Salon des Indépendants in Paris between 1888 and 1890 and in Brussels in 1890; both salons showed small commemorative groups of his work in 1891. One-man shows of his work did not occur until 1892.
