„I have seen big painting here. When I had looked at all the paintings by all the masters I had known I could not help saying to myself all the time, it's very pretty but it's not all yet. It ought to be better, but now I have seen what I always thought ought to have been done and what did not seem to me impossible. O what satisfaction it gave me to see the good Spanish work so good so strong so reasonable so free from every affectation. It stands out like nature itself.“
— Thomas Eakins American painter 1844 - 1916
