John Duncan (1866–1945) was a Scottish painter closely associated with the later phase of the Pre-Raphaelite movement and Symbolism. His art was inspired by Arthurian legends, Celtic folklore, and other mythological subjects. Although Duncan shared the Pre-Raphaelite’s distaste for materialism and the ugliness of the industrialized world and was driven by the same spirituality and idealism, his graphical style sets his art apart from his contemporaries and likens it to Art Nouveau. Some of his peers claimed he was a madman, Duncan admitted to hearing ‘faerie music’ while he painted. Duncan’s account seems to imply he may have had a sense of the longing C.S. Lewis called “Joy”.
