(1795-1821) English poet who made frequent use of Greek Myths in his poems. Of his long works, Endymion: A Poetic Romance (1818) is minor, and the more ambitious fragments "Hyperion" (1820) and "The Fall of Hyperion: A Dream" (written 1819; 1848) were abandoned. All these works owe a debt to Ovid, although the actual source for Endymion is more obscure. While JK set greatest store in his long poems, his shorter narratives are more accomplished and have exerted a greater influence over modern fantasy. "Lamia" (1820), telling the story – from Anatomy of Melancholy (1621) by Robert Burton (1577-1640) – of a Greek philosopher who unwittingly marries the eponymous serpent woman (> Lamia), and "La Belle Dame Sans Merci" (1820) are tales of erotic entrapment and devastation; the latter poem, with its medieval venue and spare form, is widely echoed in modern fantasy. "The Eve of St Agnes" (1820), also probably derived from Burton, gives a happy ending to a story of erotic enchantment: its lovers, both human, escape an "elfin-storm from faery land", cheating, very unusually, the world of Faerie.
