In 1932 Orozco made a brief trip to Europe, where he viewed the art of England, France, Spain, and Italy. Although he was impressed with the paintings of Pablo Picasso, his even deeper admiration of the Byzantine mosaics of Rome and Ravenna is reflected in his great series of murals (1932–34) in the Baker Library at Dartmouth College in Hanover, New Hampshire. Orozco created two series of murals there that correlated to two main scenes, The Coming of Quetzalcoatl and The Return of Quetzalcoatl. This dichotomy contrasted the stages of human progression from a primeval, non-Christian paradise to a Christian, capitalist hell. Byzantine mosaics also clearly influenced the pictorial style of Modern Migration of the Spirit, but such scenes as Gods of the Modern World and the Quetzalcoatl murals achieve unique levels, respectively, of grotesqueness and of sweeping force.
