David Scott's (1806–1849) most ambitious historical work was the triptych "Sir William Wallace, Scottish Wars: the Spear and English War: the Bow" (1843). He also produced etchings for versions of Coleridge's "Ancient Mariner", Bunyan's "Pilgrim's Progress" and J. P. Nichol's "Architecture of the Heavens" (1850). Because of this early death he was known to, and admired by, the Pre-Raphaelite brotherhood mainly through his brother William Bell Scott (1811–1890), who became a close friend of founding member D. G. Rossetti. The London-based Pre-Raphaelites rejected the formalism of Mannerist painting after Raphael. Bell Scott was patronised by the Pre-Raphaelite collector James Leathart. His most famous work, "Iron and Coal" was one of the most popular Victorian images and one of the few to fulfill the Pre-Raphaelite ambition to depict the modern world.
