Paul Delvaux was a Belgian painter noted for his dream-like scenes of women, classical architecture, trains and train stations, and skeletons, often in combination. He is often considered a surrealist, although he only briefly identified with the Surrealist movement. He was influenced by the works of Giorgio de Chirico and René Magritte, but developed his own fantastical subjects and hyper-realistic styling, combining the detailed classical beauty of academic painting with the bizarre juxtapositions of surrealism.

Giuseppe Maria Alberto Giorgio de Chirico was an Italian artist and writer born in Greece. In the years before World War I, he founded the scuola metafisica art movement, which profoundly influenced the surrealists. His best-known works often feature Roman arcades, long shadows, mannequins, trains, and illogical perspective. His imagery reflects his affinity for the philosophy of Arthur Schopenhauer and of Friedrich Nietzsche, and for the mythology of his birthplace.
