Captain Ahab resin character jug produced in England circa 1975. Captain Ahab is a fictional character and one of the main protagonists in Herman Melville's "Moby Dick" (1851). He is the monomaniacal captain of the whaling ship Pequod. On a previous voyage, the white whale Moby Dick bit off Ahab's leg, and he now wears a prosthetic leg made out of whalebone. The whaling voyage of the Pequod ends up as a hunt for revenge on the whale, as Ahab forces the crew members to support his fanatical mission. When Moby Dick is finally sighted, Ahab's hatred robs him of all caution, and the whale drags him to his death beneath the sea and sinks the Pequod. Rising from the depths of the ocean, the white whale Moby Dick forms the handle of the jug.
