Moby-Dick; or, The Whale is a novel by Herman Melville, first published in 1851. It is considered to be one of the Great American Novels and a treasure of world literature. The story tells the adventures of wandering sailor Ishmael, and his voyage on the whaleship Pequod, commanded by Captain Ahab. Ishmael soon learns that Ahab has one purpose on this voyage: to seek out Moby Dick, a ferocious, enigmatic white sperm whale. In a previous encounter, the whale destroyed Ahab's boat and bit off his leg, which now drives Ahab to take revenge. In Moby-Dick, Melville employs stylized language, symbolism, and the metaphor to explore numerous complex themes. Through the journey of the main characters, the concepts of class and social status, good and evil, and the existence of God are all examined, as the main characters speculate upon their personal beliefs and their places in the universe. The narrator's reflections, along with his descriptions of a sailor's life aboard a whaling ship, are woven into the narrative along with Shakespearean literary devices, such as stage directions, extended soliloquies, and asides. The book portrays destructive obsession and monomania, as well as the assumption of anthropomorphism-projecting human instincts, characteristics and motivations onto animals. Moby Dick is ruthless in attacking the sailors who attempt to hunt and kill him, but it is Ahab who invests Moby Dick's natural instincts with malignant and evil intentions. In fact, it is not the whale but the crippled Ahab who alone possesses this characteristic. Moby-Dick has been classified as American Romanticism. It was first published by Richard Bentley in London on October 18, 1851, in an expurgated three-volume edition titled The Whale, and weeks later as a single volume, by New York City publisher Harper and Brothers as Moby-Dick; or, The Whale on November 14, 1851. The book initially received mixed reviews, but Moby-Dick is now considered part of the Western canon, and at the center of the canon of American novels. "Moby-Dick" begins with the line "Call me Ishmael." According to the American Book Review's rating in 2011, this is one of the most recognizable opening lines in Western literature. Herman Melville (August 1, 1819 - September 28, 1891) was an American novelist, short story writer, essayist, and poet. He is best known for his novel Moby-Dick. His first three books gained much contemporary attention (the first, Typee, became a bestseller), but after a fast-blooming literary success in the late 1840s, his popularity declined precipitously in the mid-1850s and never recovered during his lifetime. When he died in 1891, he was almost completely forgotten. It was not until the "Melville Revival" in the early 20th century that his work won recognition, especially Moby-Dick, which was hailed as one of the literary masterpieces of both American and world literature. In 1919, the unfinished manuscript for his novella Billy Budd was discovered by his first biographer. He published a version in 1924, which was quickly acclaimed by notable British critics as another masterpiece of Melville's. He was the first writer to have his works collected and published by the Library of America.
