Francis Bacon (1909-1992) took his inspiration from the classics of painting. One of the English painter's greatest obsessions was a painting from 1650: Diego Velázquez' portrait of Pope Innocent X. He never saw, or wanted to see, the original, and only knew the painting through the reproductions that he collected over many years. This "enconter" is only of the key events in the mythology of the life of Francis Bacon, who painted over 40 portraits of popes between 1949 and 1971, always after Velázquez' portrait.
