Guillaume Cornelis van Beverloo (born 3 July 1922, Liege, Belgium), better known under his pseudonym Corneille, is a Dutch artist who studied art at the Academy of Art in Amsterdam, the Netherlands.In 1948 he became one of the founders of the Reflex movement, and in 1949 helped found the Cobra group in Denmark, which had great influence on Scandinavian art. He was active within the group from the beginning, not only painting but also publishing poetry in the Cobra magazine. The poetic Corneille was strongly influenced by the artists MirÃ³ and Klee. After the group dissolved in 1951 he moved to Paris and began collecting African art. These primitive artifacts became evident in his works, influencing him to take on a more imaginative style such as depicting landscapes seen from a bird's eye view, using images of exotic birds and producing more stylized forms.
