"How I miss you here , and how delighted you would have been to see Velázquez, who in himself alone is worth the journey.. .He is the painter of painters. He did not astonish me, but delighted me."

“My dear Duret, I went to see Monet yesterday. I found him heart-broken and completely on the rocks. He asked me to find him someone who would take from ten to twenty of his paintings at their choice, for 111 fr. apiece. Shall we do it between us, making 500 fr. each? Naturally, no one, least of all he, must know that it is we who are doing it..”

“You would hardly believe, my dear fellow, how difficult it is to clap a solitary figure on a canvas and to concentrate the entire interest on that one solitary figure without it ceasing to be lively and full.. .Your portrait is an outstandingly sincere work. I remember as though it were yesterday the rapid, summary fashion in which I dealt with the glove of the ungloved hand. And when you said to me, at that very moment, 'Please not another touch', I felt we were so perfectly attuned that I couldn't resist the impulse to embrace you. Ah! Heaven send that no one takes it into his head later on to stick that portrait into a public collection!”

“Ah! Women.. .I met one yesterday on the Pont de l'Europe . She was walking the way only a Parisienne knows how to walk, but with an extra something, even more assured. I'll remember that. There are some things that will always be engraved on my mind.”
