Cy Twombly. Apollo & Artist, 1975on lists: the Cy Twombly website is very generous. It has all his work from 1951 to 2010 in 5-year periods. If one is feeling desperate, one could do worse than to pick a year and look at all the drawings and paintings he did that year. And then some other time, look at a completely different year. I've always thought his work was about handwriting. The drawings seem to be full of written instructions for how to see.
The Menil Centre in Houston has a pavilion dedicated to Twombly, solid, but it feels inside like a white canvas tent so the light is pale and completely diffuse. On the Menil website it doesn't look at all as I remember it: I remember paintings the size of the walls in quite small spaces. They were wonderful.
Some work makes me very hopeful.
