Line dance

Sean Scully once told me about his early days as a plasterer’s mate. At the age of 17 he was helping a craftsman who would often accidentally drop a good deal of plaster on his youthful assistant’s head, especially after a midday break in the pub. Scully spent his own lunchtimes differently. He would roar on his scooter to the Tate Gallery, and spend the time staring at a single picture: ‘The Chair’ by Vincent van Gogh.

That picture is one of two reference points in Sea Star, his beautiful exhibition at the National Gallery. Scully pays homage to it in two groups of three paintings, entitled ‘Arles Abend Vincent’ and ‘Arles Abend Deep’. Neither looks much like a chair; the panels resemble, if anything, sections of a wall (if not a plastered one). Scully has, in fact, taken a series of photographs of dry stone walls on the island of Aran.
