The Fighting Temeraire by Turner is one of the most popular paintings in the National Gallery. This image is a detail of the sunset taken from The Fighting Temeraire.
The 98-gun ship Temeraire played a distinguished role in Nelson's victory at the Battle of Trafalgar in 1805, after which she was known as the Fighting Temeraire. The ship remained in service until 1838 when she was decommissioned and towed from Sheerness to Rotherhithe to be broken up.
The painting was thought to represent the decline of Britain's naval power. The Temeraire is shown travelling east, away from the sunset, even though Rotherhithe is west of Sheerness, but Turner's main concern was to evoke a sense of loss, rather than to give an exact recording of the event. The spectacularly colourful setting of the sun draws a parallel with the passing of the old warship. By contrast the new steam-powered tug is smaller and more prosaic.
