This is an automatically translated description
The novel is partly based on real events that happened in 1820 with the whaling ship Essex (in the novel it is called Pequod). The work contains a lot of symbolism and subtext.
The white whale nicknamed Moby Dick destroyed more than a dozen ships and sailors. And it was he who bit off Captain Ahab's leg a few years ago. Ahab wants to take revenge on the animal, and he doesn't care how or at what cost.
