Moby-Dick of course is the tale of Ishmael the narrator, his voyage on the Nantucker whaler Pequod, and Captain Ahab's hunt for the great White Whale. Somehow I snuck through my literature classes in high school without reading this, and am just now catching up.
The book highly stylized, and epic in scope, turning the whale hunt into a setpiece for ruminations on existence, fate, religion, and the nature of man. It presents short chapters that often digress and philosophize, or describe the hunt of whaling (the anatomy of sperm whales vs right whales, the manner of cutting a whale and mining its oil, the skeletons of whales, etc). These are interspersed with active scenes of the Pequod's hunt for Moby-Dick. This dispersal made me almost feel at sea on a hunt: The dry, ritualized background chapters acting as the dry, ritualized days at sea when nothing happens between whale sightings.
Ahab chases the white whale, symbolic of fate, or God; anything inescapable, powerful, and mysterious. It's tragic that Ahab is given every opportunity to turn back from his suicidal chase. We the readers, as Ishmael, on the Pequod as an observer, are caught up in the tragedy, and are the only ones to be rescued by the motherly Rachel, forlornly searching the wide seas.
