While in Rome he executed a large symbolical painting, entitled the "Agony of Discord, or the Household Gods Destroyed."
The works of his later years include "Vasco da Gama encountering the Spirit of the Storm," a picture immense in size and most powerful in conception finished in 1842, and now preserved in the Trinity House, Leith; the "Duke of Gloucester entering the Water Gate of Calais" (1841); the "Alchemist" (1818), "Queen Elizabeth at the Globe Theatre" (1840) and "Peter the Hermit" (1845), remarkable for varied and elaborate character painting; and "Ariel and Caliban" (1837) and the "Triumph of Love" (1846), distinguished by beauty of colouring and depth of poetic feeling.
Two of these—the "Monograms of Man" and the illustrations to Coleridge's Ancient Mariner—were etched by his own hand, and published in 1831 and 1837 respectively, while his subjects from The Pilgrim's Progress and Nichol's Architecture of the Heavens were issued after his death.
His main masterpiece is "Vasco de Gama at the Cape of Good Hope" which is held at Trinity House of Leith.
