Its origin is attributed to English author Horace Walpole, with his 1764 novel "The Castle of Otranto", subtitled (in its second edition) "A Gothic Story." The effect of Gothic fiction feeds on a pleasing sort of terror, an extension of Romantic literary pleasures that were relatively new at the time of Walpole's novel. It originated in England in the second half of the 18th century and had much success in the 19th, as witnessed by Mary Shelleys "Frankenstein" and the works of Edgar Allan Poe. Another well known novel in this genre, dating from the late Victorian era, is Bram Stokers "Dracula". The name "Gothic" refers to the (pseudo)-medieval buildings, emulating Gothic architecture, in which many of these stories take place. This extreme form of romanticism was very popular in England and Germany. The English Gothic novel also led to new novel types such as the German "Schauerroman" and the French "Georgia".  - Interview with the Vampire is a debut gothic horror and vampire novel by American author Anne Rice, published in 1976. Based on a short story Rice wrote around 1968, the novel centers on vampire Louis de Pointe du Lac, who tells the story of his life to a reporter. Rice composed the novel shortly after the death of her young daughter Michelle, who served as an inspiration for the child-vampire character Claudia. Though initially the subject of mixed critical reception, the book was followed by a large number of widely popular sequels, collectively known as "The Vampire Chronicles". A film adaptation was released in 1994, starring Brad Pitt and Tom Cruise, and the novel has been adapted as a comic three times.  - Anne Rice (born Howard Allen Frances O'Brien; October 4, 1941) is an American author of gothic fiction, Christian literature, and erotica.
