My dear Theo, Thanks for your letter of this morning. Yesterday I saw the Corot exhibition. It included a painting of the 'Mount of Olives'; I'm glad he painted that. On the right, a group of olive trees, dark against the darkening blue sky; in the background hills covered with shrubs and a couple of tall trees, above them the evening star.... I've also seen the Louvre and the Luxembourg, as you can imagine. The Ruisdaels in the Louvre are magnificent, especially 'The bush', 'The breakwater' and 'The ray of sunlight'. I wish you could see the small Rembrandts there, the 'Supper at Emmaus', and two pendants, 'The philosophers'.
