“Harry,” said Basil Hallward, looking him straight in the face, “every portrait that is painted with feeling is a portrait of the artist, not of the sitter. The sitter is merely the accident, the occasion. It is not he who is revealed by the painter; it is rather the painter who, on the coloured canvas, reveals himself. The reason I will not exhibit this picture is that I am afraid that I have show in it the secret of my own soul.”
Oscar Wilde, The Picture of Dorian Gray
