Metaphysics is an artistic movement born at the beginning of the twentieth century thanks to the Italian painter Giorgio de Chirico. The metaphysical term is generally used to express what exists beyond the physical appearance of reality. The paintings of metaphysical painting are based on absolute immobility: the figures, the objects, seem frozen in a timeless moment. In compositions, the use of perspective, as well as light and shadows are often distorted and unnatural and are used to emphasize the mood of the artist. In other respects, the American artist Edward Hopper shares this metaphysical character in some of the urban scenes he has painted.
