Like most ambitious artists, Julian Cooper has been pulled this way and that by seemingly conflicting influences. The son and grandson of Lake District landscape painters — his mother was a sculptor — he fell among abstractionists at his London art college, Goldsmith’s, in the late 1960s. But when I first saw his work in the early 1980s, he had emerged as a flagrant figurative painter, with a series of large canvases depicting scenes from Malcolm Lowry’s novel Under the Volcano.
