The self-portraits reflect an unusually high degree of self-scrutiny. Often they were intended to mark important periods in his life, for example the mid-1887 Paris series were painted at the point where he became aware of Claude Monet, Paul Cezanne and Signac. In Self-Portrait with Grey Felt Hat, heavy strains of paint spread outwards across the canvas. It is one of his most renowned self-portraits of that period, "with its highly organized rhythmic brushstrokes, and the novel halo derived from the Neo-impressionist repertoire was what Van Gogh himself called a 'purposeful' canvas".
There are more than 600 letters from Vincent to Theo and around 40 from Theo to Vincent. There are 22 to his sister Wil, 58 to the painter Anthon van Rappard, 22 to Émile Bernard as well as individual letters to Paul Signac, Paul Gauguin and the critic Albert Aurier. Some are illustrated with sketches. Many are undated, but art historians have been able to place most in chronological order. Problems in transcription and dating remain, mainly with those posted from Arles. While there Vincent wrote around 200 letters in Dutch, French and English. There is a gap in the record when he lived in Paris as the brothers lived together and had no need to correspond.
Van Gogh had no recollection of the event, suggesting that he may have suffered an acute mental breakdown. The hospital diagnosis was "acute mania with generalised delirium", and within a few days the local police ordered that he be placed in hospital care. Gauguin immediately notified Theo, who on 24 December had proposed marriage to his old friend Andries Bonger's sister Johanna. That evening Theo rushed to the station to board a night train to Arles. He arrived on Christmas Day and comforted Vincent, who seemed to be semi-lucid. That evening he left Arles for the return trip to Paris.
I remember in the book that Caractacus was married. There was no love interest, no love story. So I think bringing Truly Scrumptious in works very well because we had assumed he was a widower. And they couldn't have picked a better Truly Scrumptious than Sally [Sally Ann Howes]. They came up with Sally Ann and I heard her voice, and it was the richest contralto. She auditioned with "The Lovely Lonely Man" and I thought, "My God, this girl is great!" and then she was stunningly beautiful. She loved those kids and they loved her, which I think comes across on the screen. They just thought a great deal of her and she spent a lot of time with them, you know, between shots - telling stories and playing games during all those long waiting periods.
Van Gogh moved to Paris in March 1886 where he shared Theo's rue Laval apartment in Montmartre, and studied at Fernand Cormon's studio. In June the brothers took a larger flat at 54 rue Lepic. In Paris, Vincent painted portraits of friends and acquaintances, still life paintings, views of Le Moulin de la Galette, scenes in Montmartre, Asnières and along the Seine. In 1885 in Antwerp he had become interested in Japanese ukiyo-e woodblock prints, and had used them to decorate the walls of his studio; while in Paris he collected hundreds of them. He tried his hand at Japonaiserie, tracing a figure from a reproduction on the cover of the magazine Paris Illustre, The Courtesan or Oiran (1887), after Keisai Eisen, which he then graphically enlarged in a painting.
In 1892 Émile Bernard organised a small solo show of Van Gogh's paintings in Paris, and Julien Tanguy exhibited his Van Gogh paintings with several consigned from Johanna van Gogh-Bonger. In April 1894 the Durand-Rue Gallery in Paris agreed to take 10 paintings on consignment from Van Gogh's estate. In 1896, the Fauvist painter Henri Matisse, then an unknown art student, visited John Peter Russell on Belle Île off Brittany. Russell had been a close friend of Van Gogh; he introduced Matisse to the Dutchman's work, and gave him a Van Gogh drawing. Influenced by Van Gogh, Matisse abandoned his earth-coloured palette for bright colours.
