Why Ahab's leg is about a wound that becomes a compass
The whalebone prosthesis is the prism. Moby-Dick locates obsession in the part of the captain that is no longer there.
Captain Ahab walks the Pequod's deck on a leg carved from a sperm-whale jaw. The wood that replaced his flesh comes from the same animal that took it. He stands on his enemy.
Melville locates the obsession exactly. Not in the leg that remains. In the leg that doesn't. The vacant ankle is the instrument that points the entire ship at one specific whale.
Most wounds heal into stories. Ahab's heals into a heading. The book studies the difference. A compass made of grievance still points consistently. It just doesn't point home.
Every life has its missing leg. Melville's small brutal claim. Some wounds get you home. Others quietly command the entire crew somewhere the rest of the ship never agreed to go.
