Another in a long line of tributes to Cy Twombly: the artist who taught me that if you draw enough, no matter what it looks like, it's considered art.

His art is much deeper than that, of course. It was just that before I saw him at the wonderful Menil collection in Houston, I never understood modern art. His works made me smile for two reasons: first, I couldn't believe that someone painted those scribbles and got away with calling them art and making money on them; and second, they truly were wonderful.
