I think Picasso was, without doubt, the greatest portraitist of the 20th century, if not any other century.
David HockneyWhat the art historians had forgotten is that in Chinese, Japanese, Persian, and Indian art, they never painted shadows. Why did they paint shadows in European art? Shadows are because of optics. Optics need shadows and strong light. Strong light makes the deepest shadows. It took me a few years to realize fully that the art historians didn't grasp that. There are a lot of interesting new things, ideas, pictures.
