I went to the Cy Twombly exhibition yesterday and it is breathtaking. My favourite, the triptych ‘Hero and Leandro’ is there, in a really unexpected place, staggeringly touching, and full of the inevitable movement of tragedy. The explosion of colour in the two Four Seasons cycles is just as stunning as I remembered from seeing them in New York. The hanging is very well done in a vaguely chronological order. The paintings are incredibly suggestive and sensual, full of life and energy, but all very masterly controlled and cerebral. It really affected me emotionally and intellectually.
