Dougie Vipond visits the River Tay, which runs from its source in the Highlands, past Dundee and out to sea. For centuries, the Tay estuary has shaped how creative people have expressed themselves. Starting at McDuff's Cross, the author Robin Crawford explains the Tay's link to Shakespeare - who was said to have drawn inspiration for his play Macbeth from this area. Pre-Raphaelite painters Turner and Millais knew the area well, Beatrix Potter imagined some of her most famous creations on the Tay's banks, and some of Scotland's best known artists such as Raeburn and Naismith depicted the landscape in their paintings. Dougie visits the studio of a contemporary landscape artist, Helen Glassford, to find out how her view of the silvery Tay continues to have an impact on artists today. Produced by Ruth Sanderson
