Problem: Information:  - Vincent Willem van Gogh (30 March 185329 July 1890) was a Dutch Post-Impressionist painter who is among the most famous and influential figures in the history of Western art.

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.
