We went to the current exhibition at the National Portrait Gallery. People sometimes see a problem with the NPG’s remit – are they meant to collect paintings by famous artists or of famous people? But this show is unimpeachable, foregrounding an important aspect of a major artist’s work.

Bacon’s work never stopped being figurative, but he smooshes views in a way that combines and gives a sense of observer motion. It seems he often put one person’s head on a body painted from photographs of someone else. There’s also often a sense of horror, with the screaming heads and internal body parts.

The exhibition tellingly brings out his enthusiasm for certain great painters of the past: Velasquez, Rembrandt, Van Gogh, which helps situate an innovative painter within the great tradition.
