By March 1882, Mauve appears to have gone cold towards Van Gogh, and stopped replying to his letters. He had learned of Van Gogh's new domestic arrangement with an alcoholic prostitute, Clasina Maria "Sien" Hoornik (1850–1904), and her young daughter. Van Gogh had met Sien towards the end of January 1882, when she had a five-year-old daughter and was pregnant. She had previously borne two children who died, but Van Gogh was unaware of this; on 2 July, she gave birth to a baby boy, Willem. When Van Gogh's father discovered the details of their relationship, he put pressure on his son to abandon Sien and her two children. Vincent at first defied him, and considered moving the family out of the city, but in late 1883, he left Sien and the children.
Van Gogh wrote that with The Night Café he tried "to express the idea that the café is a place where one can ruin oneself, go mad, or commit a crime". When he visited Saintes-Maries-de-la-Mer in June, he gave lessons to a Zouave second lieutenant – Paul-Eugène Milliet – and painted boats on the sea and the village. MacKnight introduced Van Gogh to Eugène Boch, a Belgian painter who sometimes stayed in Fontvieille, and the two exchanged visits in July.
Van Gogh painted several landscapes with flowers, including roses, lilacs, irises, and sunflowers. Some reflect his interests in the language of colour, and also in Japanese ukiyo-e. There are two series of dying sunflowers. The first was painted in Paris in 1887 and shows flowers lying on the ground. The second set was completed a year later in Arles, and is of bouquets in a vase positioned in early morning light. Both are built from thickly layered paintwork, which, according to the London National Gallery, evoke the "texture of the seed-heads".
While in Asnières Van Gogh painted parks, restaurants and the Seine, including Bridges across the Seine at Asnières. In November 1887, Theo and Vincent befriended Paul Gauguin who had just arrived in Paris. Towards the end of the year, Vincent arranged an exhibition alongside Bernard, Anquetin, and probably Toulouse-Lautrec, at the Grand-Bouillon Restaurant du Chalet, 43 avenue de Clichy, Montmartre. In a contemporary account, Bernard wrote that the exhibition was ahead of anything else in Paris. There Bernard and Anquetin sold their first paintings, and Van Gogh exchanged work with Gauguin. Discussions on art, artists, and their social situations started during this exhibition, continued and expanded to include visitors to the show, like Camille Pissarro and his son Lucien, Signac and Seurat. In February 1888, feeling worn out from life in Paris, Van Gogh left, having painted more than 200 paintings during his two years there. Hours before his departure, accompanied by Theo, he paid his first and only visit to Seurat in his studio.
Theo kept all of Vincent's letters to him; Vincent kept few of the letters he received. After both had died, Theo's widow Johanna arranged for the publication of some of their letters. A few appeared in 1906 and 1913; the majority were published in 1914. Vincent's letters are eloquent and expressive and have been described as having a "diary-like intimacy", and read in parts like autobiography. The translator Arnold Pomerans wrote that their publication adds a "fresh dimension to the understanding of Van Gogh's artistic achievement, an understanding granted us by virtually no other painter".
We bought a bedroom set and was very excited to get it delivered. However, when it got delivered, we realized that the salesperson failed to tell us that we needed a bunky board rather than a box spring, and the bed was 5 feet tall with the platform! (Keeping in mind I bought all the pieces of furniture from the same company). The bed was as tall as me! I called the company while the delivery guys were still here, but the salesperson said she would call me back and never did. I finally got ahold of the manager the next day, who was going to charge me another $100 for the exchange and delivery. I later found out that the bunky board was simply a piece of plywood that you can easily buy for much cheaper, and that this situation happened to people all the time; especially to elderly people.
Albert Aurier praised his work in the Mercure de France in January 1890, and described him as "a genius". In February Van Gogh painted five versions of L'Arlésienne (Madame Ginoux), based on a charcoal sketch Gauguin had produced when she sat for both artists in November 1888.[note 10] Also in February, Van Gogh was invited by Les XX, a society of avant-garde painters in Brussels, to participate in their annual exhibition. At the opening dinner a Les XX member, Henry de Groux, insulted Van Gogh's work. Toulouse-Lautrec demanded satisfaction, and Signac declared he would continue to fight for Van Gogh's honour if Lautrec surrendered. De Groux apologised for the slight and left the group. Later, while Van Gogh's exhibit was on display with the Artistes Indépendants in Paris, Claude Monet said that his work was the best in the show. After the birth of his nephew, Van Gogh wrote, "I started right away to make a picture for him, to hang in their bedroom, branches of white almond blossom against a blue sky."
During the last six or seven months of the year 1889, he has also created at least fifteen paintings of olive trees, a subject which he considered as demanding and compelling. Among these works are Olive Trees with the Alpilles in the Background (1889), about which in a letter to his brother Van Gogh wrote, "At last I have a landscape with olives".While in Saint-Rémy, Van Gogh spent time outside the asylum, where he painted trees in the olive groves. In these works natural life is rendered as gnarled and arthritic as if a personification of the natural world, which are, according to Hughes, filled with "a continuous field of energy of which nature is a manifestation".
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 July 1869 Van Gogh's uncle Cent obtained a position for him at the art dealers Goupil & Cie in The Hague. After completing his training in 1873, he was transferred to Goupil's London branch at Southampton Street, and took lodgings at 87 Hackford Road, Stockwell. This was a happy time for Van Gogh; he was successful at work, and at 20 was earning more than his father. Theo's wife later remarked that this was the best year of Vincent's life. He became infatuated with his landlady's daughter, Eugénie Loyer, but was rejected after confessing his feelings; she was secretly engaged to a former lodger. He grew more isolated, and religiously fervent. His father and uncle arranged a transfer to Paris in 1875, where he became resentful of issues such as the degree to which the firm commodified art, and was dismissed a year later.
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 himself brought this period to an end. Oppressed by homesickness—he painted souvenirs of Holland—and loneliness, he longed to see Theo and the north once more and arrived in Paris in May 1890. Four days later he went to stay with a homeopathic doctor-artist, Paul-Ferdinand Gachet, a friend of Pissarro and Paul Cézanne, at Auvers-sur-Oise. Back in a village community such as he had not known since Nuenen, four years earlier, van Gogh worked at first enthusiastically; his choice of subjects such as fields of corn, the river valley, peasants’ cottages, the church, and the town hall reflects his spiritual relief. A modification of his style followed: the natural forms in his paintings became less contorted, and in the northern light he adopted cooler, fresh tonalities. His brushwork became broader and more expressive and his vision of nature more lyrical. Everything in these pictures seems to be moving, living. This phase was short, however, and ended in quarrels with Gachet and feelings of guilt at his financial dependence on Theo (now married and with a son) and his inability to succeed.
The police found van Gogh in his room the next morning, and admitted him to the Hôtel-Dieu hospital. Theo arrived on Christmas Day to see van Gogh, who was weak from blood loss and having violent seizures. The doctors assured Theo that his brother would live and would be taken good care of, and on January 7, 1889, van Gogh was released from the hospital.
After seeing the portrait of Adolphe Monticelli at the Galerie Delareybarette, Van Gogh adopted a brighter palette and a bolder attack, particularly in paintings such as his Seascape at Saintes-Maries (1888). Two years later, Vincent and Theo paid for the publication of a book on Monticelli paintings, and Vincent bought some of Monticelli's works to add to his collection.
