To help mark the 950th anniversary of the Battle of Hastings, Sotheran has donated a copy of Daniel Maclise's wonderful 1866 work The Story of the Norman Conquest to Battle Museum in East Sussex where it all happened. To commemorate the 800th anniversary of the battle Maclise reworked the Bayeux Tapestry as a frieze in a neo-Classical style. He clearly favoured the Normans, as they are seen praying righteously on the eve of the battle while the Saxons are drinking mead and larking about. It's very difficult to defend a hill with a hangover. Still, they played their part in the birth of modern Britain, and the nation's fondness for the underdog may well have started with an arrow that pierced Harold's eye and flew on to become a Spitfire in the Battle of Britain, a tennis ball from Tim Henman's racquet and a towel thrown in by David Cameron. Duke William of Normandy changed everything - our language, our governance, our sense of identity - and that seems worth commemorating.
