“Who were the two artists of ancient times who competed to see who could paint the visible world most faithfully? ‘Now I shall prove to you that I am the best’, said the first, showing the other a curtain which he had painted. ‘Well, draw back the curtain’, said the adversary, ‘and let us see the picture’. ‘The curtain is the picture’, replied the first with a laugh.” (Nikos Kazantzakis)
