The Pre-Raphaelite Brotherhood (also known as the Pre-Raphaelites) was a group of English painters, poets, and critics, founded in 1848 by Dante Gabriel Rossetti, William Michael Rossetti, James Collinson, John Everett Millais, Frederic George Stephens, Thomas Woolner and William Holman Hunt.
The group's intention was to reform art by rejecting what they considered to be the mechanistic approach first adopted by the Mannerist artists who succeeded Raphael and Michelangelo. They believed that the Classical poses and elegant compositions of Raphael in particular had been a corrupting influence on the academic teaching of art. Hence the name "Pre-Raphaelite". In particular, they objected to the influence of Sir Joshua Reynolds, the founder of the English Royal Academy of Arts. They called him "Sir Sloshua", believing that his broad technique was a sloppy and formulaic form of academic Mannerism. In contrast, they wanted to return to the abundant detail, intense colours, and complex compositions of Quattrocento Italian and Flemish art.
The Pre-Raphaelites have been considered the first avant-garde movement in art, though they have also been denied that status, because they continued to accept both the concepts of history painting and of mimesis, or imitation of nature, as central to the purpose of art. However, the Pre-Raphaelites undoubtedly defined themselves as a reform-movement, created a distinct name for their form of art, and published a periodical, The Germ, to promote their ideas. Their debates were recorded in the Pre-Raphaelite Journal. [Wikipedia]
