Q:Information: - Vincent Willem van Gogh (30 March 185329July 1890) was a Dutch Post-Impressionist painter who is among the most famous and influential figures in the history of Western art. In just over a decade he created about 2,100 artworks, including around 860 oil paintings, most of them in the last two years of his life. They include landscapes, still lifes, portraits and self-portraits, and are characterised by bold colours and dramatic, impulsive and expressive brushwork that contributed to the foundations of modern art. His suicide at 37 followed years of mental illness and poverty. - The Roulin Family is group of portrait paintings Vincent van Gogh executed in Arles in 1888 and 1889 on Joseph , his wife Augustine and their three children : Armand , Camille and Marcelle . This series is unique in many ways . Although Van Gogh loved to paint portraits , it was difficult for financial and other reasons for him to find models . So , finding an entire family that agreed to sit for paintings -- in fact , for several sittings each -- was a bounty . Joseph Roulin became a particularly good , loyal and supporting friend to Van Gogh during his stay in Arles . To represent a man he truly admired was important to him . The family , with children ranging in age from four months to seventeen years , also gave him the opportunity to produce works of individuals in several different stages of life . Rather than making photographic - like works , Van Gogh used his imagination , colors and themes artistically and creatively to evoke desired emotions from the audience . - Oil painting is the process of painting with pigments with a medium of drying oil as the binder. Commonly used drying oils include linseed oil, poppy seed oil, walnut oil, and safflower oil. The choice of oil imparts a range of properties to the oil paint, such as the amount of yellowing or drying time. Certain differences, depending on the oil, are also visible in the sheen of the paints. An artist might use several different oils in the same painting depending on specific pigments and effects desired. The paints themselves also develop a particular consistency depending on the medium. The oil may be boiled with a resin, such as pine resin or frankincense, to create a varnish prized for its body and gloss. What is the relationship between 'the roulin family' and 'oil paint'?
