Welsh Turner mountain scene revealed to be set in Scotland Now artistic detective work by Professor Murdo MacDonald, of Dundee University, and Eric Shanes, a former chairman of the Turner Society, has proved the painting is a depiction of the Loch Lomond area. The Turner painting (top) and the view of Ben Lomond from Glen Douglas (CATERS/COLIN MEARNS) Written by the Scots poet James Macpherson, the poem follows dismissed general Hidallan, who pay a visit to his father Lamor. Disgusted and ashamed, Lamor kills his disgraced son before turning his sword on himself. Prof Macdonald said: "The seated man in Turner's painting is undoubtedly Lamor, holding his glinting sword and with a semi-circular form to the left of him that surely represents his discarded shield. At his feet lies the body of his slain son. He and Mr Shanes also uncovered a drawing by Turner in the Tate Gallery showing a view of Loch Lomond, which they call the "clear basis of the painting." He continued: "The Ben Lomond work becomes a pivot between Turner's seascapes and his imaginary landscapes. So, for the first time since the title and painting became detached from one another, it is possible to appreciate fully the psychological balance of Turner's first exhibits in oils at the Royal Academy. He added: "The painting is significant in another sense. It seems to be Turner's first response in oil paint to poetry based on a landscape he had himself seen, and that is, of course, one of the defining themes of his career as a whole.
