The Castle of Otranto is a 1764 novel by Horace Walpole. It is generally regarded as the first gothic novel, initiating a literary genre which would become extremely popular in the later 18th century and early 19th century. Thus, Walpole, by extension, is arguably the forerunner to such authors as Charles Maturin, Ann Radcliffe, Bram Stoker, Edgar Allan Poe and Daphne du Maurier. - Wikipedia
