Correggio, kuh REHJ oh (1489?-1534), was one of the greatest painters of the Italian Renaissance. His most important works are frescoes (paintings on damp plaster) on two church domes in Parma, Italy. In these paintings, Correggio created the illusion that the ceilings open into the sky and many divine figures inhabit the clouds above the viewer's head. This dramatic illusion influenced the paintings of the baroque period of the late 1500's and the 1600's.
