 Although Bacon avoided seeing the original, the painting remains the single greatest influence on him; its presence can be seen in many of his best works from the late 1940s to the early 1960s.In Bacon's version of the 17th century masterpiece, the Pope is shown screaming yet his voice is "silenced" by the enclosing drapes and dark rich colors.The dark colors of the background lend a grotesque and nightmarish tone to the painting.
