utilized such material; Robert W. Chambers' The Demoiselle d'Ys (from The King in Yellow, 1895) and A. Merritt in Creep, Shadow! (1934) both drew on the Breton legend of the lost city of Ys, while "The Lay of Aotrou and Itroun" (1930) by J. R. R. Tolkien is a narrative poem based on the Breton legend of the Corrigan. Classical fantasy Classical fantasy is a subgenre fantasy based on the Greek and Roman myths. Symbolism from classical mythology is enormously influential on Western culture, but it was not until the 19th century that it was used in the context of literary fantasy. Richard Garnett (The Twilight of the Gods and Other Tales, 1888, revised 1903) and John Kendrick Bangs (Olympian Nights, 1902) used the Greek myths for satirical purposes. 20th-century writers who made extensive use of the subgenre included John Erksine, who continued the satirical tradition of classical fantasy in such works as The Private Life of Helen of Troy (1925) and Venus, the Lonely Goddess (1949). Eden Phillpotts used Greek myths to make philosophical points in such fantasies as Pan and the Twins (1922) and Circe's Island (1925). Jack Williamson's The Reign of Wizardry (Unknown Worlds, 1940) is an adventure story based on the legend of Theseus. Several of Thomas Burnett Swann's novels draw on Greek and Roman myth, including Day of the Minotaur (1966). The Firebrand (1986) by Marion Zimmer Bradley and Olympic Games (2004) by Leslie What are both classical fantasy tales with feminist undertones. Guy Gavriel Kay who has made a career out of historical fantasy, set his two novels in The Sarantine Mosaic series in a parallel world heavily mirroring Justinian I's Byzantium. Fantasy of manners Fantasy of manners, aka "mannerpunk," is a subgenre that takes place within a strict, elaborate, and hierarchical social structure. Inspired by the social novels and the comedy of manners of such authors as Jane Austen and Oscar Wilde, fantasy of manners involves class struggles among genteel characters in urban environments, and while duels are permitted, witty repartee often substitutes for physical conflict. Examples of fantasy of manners include Swordspoint by Ellen Kushner and Jonathan Strange & Mr Norrell by Susanna Clarke. Fantasy steampunk Fantasy steampunk is another subgenre of historical fantasy, generally set in the Victorian or Edwardian eras. Steam technology, mixed with Victorian or Gothic-style architecture and technology, is the most widely recognized interpretation of this genre. One
