Among many honours, Clark was knighted at the unusually young age of thirty-five, and three decades later was made a life peer shortly before the first transmission of "Civilisation". Three decades after his death, Clark was celebrated in an exhibition at Tate Britain in London, prompting a reappraisal of his career by a new generation of critics and historians. Opinions varied about his aesthetic judgment, particularly in attributing paintings to old masters, but his skill as a writer and his enthusiasm for popularising the arts were widely recognised. Both the BBC and the Tate described him in retrospect as one of the most influential figures in British art of the twentieth century.
