We missed the private view of the David Jones exhibition at Pallant House last night so travelled down for lunch today.   The exhibition helps make sense of his career, less as an outsider, more as someone connected to, and aware of, the mainstream of twentieth-century art, schooled at Camberwell before the First World War and at Westminster School of Art after service in the trenches, working for Eric Gill at Ditchling, the most obvious source of influence on him,  exhibiting widely during the 1920s and recruited by Ben Nicholson to the Seven & Five Society in 1928.   He has been adopted as a Welsh artist because his father was Welsh and he was passionate about Celtic legend, but he was born in Brockley, lived after the war in Harrow, his mother was a Cockney, and he bought his shoes in Lobb’s.
