In early modern and modern folklore, they become associated with the fairies of Romance folklore and assume a diminutive size, often living underground in hills or rocks, or in wells and springs. 19th-century Romanticism attempted to restore them to full stature, often depicting them as youthful-seeming men and women of great beauty. From their depiction in Romanticism, elves entered the 20th-century high fantasy genre in the wake of the publications of J.R.R. Tolkien, especially the posthumous publication of his Silmarillion where Tolkien's treatment of the relation of light elves, dark elves, black elves and dwarves in Norse mythology is made explicit. Popular culture in the Anglosphere at the same time with Santa Claus and his helpers preserves a direct continuation of early modern folklore.”
