Moby Dick

Origin
Herman Melville's Moby-Dick is a story about the obsessive quest of Captain Ahab for revenge on Moby Dick, a white whale that on a previous whaling voyage bit off Ahab's leg at the knee. The long book which detailed almost everything about the whaling adventure was a commercial failure and out of print by the time Melville died in 1891. It was revived during the 20th century and declared an Great American Novel.
