Last Monday, I was at the National Gallery in London to attend a talk about an exhibition by Paula Rego, which opened last week. Afterwards, I was walking along the museum’s entrance with a historian friend who, pointing to the floor, said “have you seen these?”
I looked at my feet, and a kaleidoscopically coloured mosaic pavement emerged, as if silently sprawling beneath hurried gallerygoers. I couldn’t believe that, while I have spent my life going in and out of this museum, I had never thought to look down.
