Context_1 : The Pequod is a fictional 19th-century Nantucket whaling ship that appears in the 1851 novel "Moby-Dick" by American author Herman Melville. The "Pequod" and her crew, commanded by Captain Ahab, are central to the story, which, after the initial chapters, takes place almost entirely aboard the ship during a three-year whaling expedition in the Atlantic, Indian and South Pacific oceans. Most of the characters in the novel are part of the "Pequod"' s crew, including the narrator Ishmael. Context_2 : Herman Melville (August 1, 1819 September 28, 1891) was an American novelist, short story writer, and poet of the American Renaissance period. His best known works include "Typee" (1846), a romantic account of his experiences in Polynesian life, and his whaling novel "Moby-Dick" (1851). His work was almost forgotten during his last thirty years. His writing draws on his experience at sea as a common sailor, exploration of literature and philosophy, and engagement in the contradictions of American society in a period of rapid change. He developed a complex, baroque style: the vocabulary is rich and original, a strong sense of rhythm infuses the elaborate sentences, the imagery is often mystical or ironic, and the abundance of allusion extends to biblical scripture, myth, philosophy, literature, and the visual arts. fact_1 : The Pequod is a fictional 19th-century Nantucket whaling ship that appears in the 1851 novel "Moby-Dick" by American author Herman Melville. fact_2 : Herman Melville (August 1, 1819 September 28, 1891) was an American novelist, short story writer, and poet of the American Renaissance period.
