Photograph by Roger Fenton of a design for a clocksalt by Hans Holbein, dated 1543. The inscription records that Anthony Denny presented King Henry VIII with a clocksalt of this design. The central hourglass is surmounted by two cherubs holding curved metal sheets which form sundials. On their heads is a clock with a sun at the centre. The compass, (shown separately, left), would have been placed above the hour glass. Fenton, a founding member of the Royal Photographic Society, was one of the most influential photographers of the 1850s. He is best known as one of the first war photographers, from his work in the Crimea. However, he also took many highly-regarded photographs of the Royal Family as well as many superb landscapes, architectural studies and still lifes.
