His understanding of the possibilities of painting was evolving rapidly; from studying Hals he learned to portray the freshness of a visual impression, while the works of Paolo Veronese and Eugène Delacroix taught him that colour can express something by itself. This led to his enthusiasm for Peter Paul Rubens and inspired his sudden departure for Antwerp, Belgium, where the greatest number of Rubens’s works could be seen. The revelation of Rubens’s mode of direct notation and of his ability to express a mood by a combination of colours proved decisive in the development of van Gogh’s style. Simultaneously, van Gogh discovered Japanese prints and Impressionist painting. All these sources influenced him more than the academic principles taught at the Antwerp Academy, where he was enrolled. His refusal to follow the academy’s dictates led to disputes, and after three months he left precipitately in 1886 to join Theo in Paris. There, still concerned with improving his drawing, van Gogh met Henri de Toulouse-Lautrec, Paul Gauguin, and others who were to play historic roles in modern art. They opened his eyes to the latest developments in French painting. At the same time, Theo introduced him to Camille Pissarro, Georges Seurat, and other artists of the Impressionist group.
Van Gogh entered the Saint-Paul-de-Mausole asylum on 8 May 1889, accompanied by his carer, Frédéric Salles, a Protestant clergyman. Saint-Paul was a former monastery in Saint-Rémy, located less than 30 kilometres (19 mi) from Arles, and was run by a former naval doctor, Théophile Peyron. Van Gogh had two cells with barred windows, one of which he used as a studio. The clinic and its garden became the main subjects of his paintings. He made several studies of the hospital's interiors, such as Vestibule of the Asylum and Saint-Rémy (September 1889). Some of his works from this time are characterised by swirls, such as The Starry Night. He was allowed short supervised walks, during which time he painted cypresses and olive trees, including Olive Trees with the Alpilles in the Background 1889, Cypresses 1889, Cornfield with Cypresses (1889), Country road in Provence by Night (1890). In September 1889 he produced two further versions of Bedroom in Arles.
In April 1876 he returned to England to take unpaid work as a supply teacher in a small boarding school in Ramsgate. When the proprietor moved to Isleworth in Middlesex, Van Gogh went with him. The arrangement did not work out and he left to become a Methodist minister's assistant. His parents had meanwhile moved to Etten; in 1876 he returned home at Christmas for six months and took work at a bookshop in Dordrecht. He was unhappy in the position and spent his time doodling or translating passages from the Bible into English, French and German. He immersed himself in religion, and became increasingly pious and monastic. According to his flatmate of the time, Paulus van Görlitz, Van Gogh ate frugally, avoiding meat.
Van Dyke left high school in 1944, his senior year, intending to join the United States Army Air Forces for pilot training during World War II. Denied enlistment several times for being underweight, he was eventually accepted for service as a radio announcer before transferring to the Special Services and entertaining troops in the continental United States. He received his high school diploma in 2004 at the age of 78.
