Well... um... big question, but, to me Van Gogh is the finest painter of them all. Certainly the most popular, great painter of all time. The most beloved, his command of colour most magnificent. He transformed the pain of his tormented life into ecstatic beauty. Pain is easy to portray, but to use your passion and pain to portray the ecstasy and joy and magnificence of our world, no one had ever done it before. Perhaps no one ever will again.
