Offered a loan by Patrick Miller of Dalswinton, Nasmyth left in 1782 for Italy, where he remained two years furthering his studies.
Eventually, Nasmyth's strong Liberal opinions offended many of his aristocratic patrons in a politically charged Edinburgh, leading to a falling off in commissions for portraits,[1] and in 1792 he completely abandoned the genre, turning instead to landscape painting.
[7] In October 1788, when Patrick Miller sailed the world's first successful steamship, designed by William Symington, on Dalswinton Loch, Nasmyth was one of the crew.
He designed the circular temple covering St Bernard's Well by the Water of Leith (1789), and bridges at Almondell, West Lothian, and Tongland, Kirkcudbrightshire.
[11] Nasmyth died at home, 47 York Place[12] (roughly opposite the house of Sir Henry Raeburn), in Edinburgh.
[14] Nasmyth obtained several commissions as architect (in terms of a masterplan and artistic concept): notably Rosneath House and Dunglass Castle.
