oil painting has been the medium of choice for painter since
Oil painting Early works were still panel paintings on wood, but around the end of the 15th century canvas became more popular as the support, as it was cheaper, easier to transport, allowed larger works, and did not require complicated preliminary layers of gesso (a fine type of plaster). Venice, where sail-canvas was easily available, was a leader in the move to canvas. Small cabinet paintings were also made on metal, especially copper plates. These supports were more expensive but very firm, allowing intricately fine detail. Often printing plates from printmaking were reused for this purpose. The popularity of oil spread through Italy from the North, starting in Venice in the late 15th century. By 1540, the previous method for painting on panel (tempera) had become all but extinct, although Italians continued to use chalk-based fresco for wall paintings, which was less successful and durable in damper northern climates.
Abstract expressionism The movement's name is derived from the combination of the emotional intensity and self-denial of the German Expressionists with the anti-figurative aesthetic of the European abstract schools such as Futurism, the Bauhaus, and Synthetic Cubism. Additionally, it has an image of being rebellious, anarchic, highly idiosyncratic and, some feel, nihilistic.[5] In practice, the term is applied to any number of artists working (mostly) in New York who had quite different styles, and even to work that is neither especially abstract nor expressionist. California Abstract Expressionist Jay Meuser, who typically painted in the non-objective style, wrote about his painting Mare Nostrum, "It is far better to capture the glorious spirit of the sea than to paint all of its tiny ripples." Pollock's energetic "action paintings", with their "busy" feel, are different, both technically and aesthetically, from the violent and grotesque Women series of Willem de Kooning's figurative paintings and the rectangles of color in Mark Rothko's Color Field paintings (which are not what would usually be called expressionist, and which Rothko denied were abstract). Yet all four artists are classified as abstract expressionists.
