Cy Twombly, the enigmatic, controversial, operatic artist is dead at age 83. I must say I have extremely mixed feelings about Twombly. I have been moved by some of his paintings,Â am bored byÂ most of his sculpture,Â andÂ despite some misgivings believe he was a very important and influential figure in 20th century art. However, having worked with him on an exhibition at the Whitney, I got to know him slightly and as my mother often told me, “If you don’t haveÂ anything nice to say, say nothing at all.” So, in this case, I will follow her advice. Here are some of the obits, reflections and appreciations that have been written over the past few days.
