poems. It is a grimly realistic piece set during the Hundred Years War in which the doomed lovers Jehane and Robert have a last parting in a convincingly portrayed rain-swept countryside. One early minor poem was "Masters in this Hall" (1860), a Christmas carol written to an old French tune. Another Christmas-themed poem is "The Snow in the Street", adapted from "The Land East of the Sun and West of the Moon" in The Earthly Paradise. Morris met Eiríkur Magnússon in 1868, and began to learn the Icelandic language from him. Morris published translations of The Saga of Gunnlaug Worm-Tongue and Grettis Saga in 1869, and the Story of the Volsungs and Niblungs in 1870. An additional volume was published under the title of Three Northern Love Stories in 1873. In the last nine years of his life, Morris wrote a series of imaginative fictions usually referred to as the "prose romances". These novels – including The Wood Beyond the World and The Well at the World's End – have been credited as important milestones in the history of fantasy fiction, because, while other writers wrote of foreign lands, or of dream worlds, or the future (as Morris did in News from Nowhere), Morris's works were the first to be set in an entirely invented fantasy world. These were attempts to revive the genre of medieval romance, and written in imitation of medieval prose. Morris's prose style in these novels has been praised by Edward James, who described them as "among the most lyrical and enchanting fantasies in the English language." On the other hand, L. Sprague de Camp considered Morris's fantasies to be not wholly successful, partly because Morris eschewed many literary techniques from later eras. In particular, De Camp argued the plots of the novels are heavily driven by coincidence; while many things just happened in the romances, the novels are still weakened by the dependence on it. Nevertheless, large subgenres of the field of fantasy have sprung from the romance genre, but indirectly, through their writers' imitation of William Morris. Early fantasy writers like Lord Dunsany, E. R. Eddison and James Branch Cabell were familiar with Morris's romances. The Wood Beyond the World is considered to have heavily influenced C. S. Lewis's Narnia series, while J. R. R. Tolkien was inspired by Morris's reconstructions of early Germanic life in The House of the Wolfings and The Roots
