Herman Melville based his gigantic masterpiece _Moby Dick_ on fact. This is one of the most fascinating parts of that magnificent book. As mystical and symbolic as the parts and the whole may be, they are all firmly grounded in fact, in the world of nineteenth century whaling as it was. Facts crowd into the chapters, even the most novelistic ones. Tim Severin has made a career of replicating historic vessels, using them to trace the supposed routes of their historic sailors, and then writing about the results. In _In Search of Moby Dick: The Quest for the White Whale_ (Basic Books), he does not plunder Melville's great work, but actually expands it. Using _Moby Dick_ and other Melville texts, he has gone on an adventure to find the white sperm whale, and although he never brings home the fabulous creature, he does indeed find it in ways that demonstrate that even a century and a half after the white whale entered literature, he still exists as fact as well as fable.
Severin's curious quest takes him first to the island Melville described in his bestseller _Typee_, and then to islands where Melville never visited, but where there are still whalemen who still harpoon whales. The descriptions of the dangers of the hunts on which Severin accompanied the islanders are vivid and memorable. He finds, intriguingly, that the island legends of the white whale are in many ways the same as those of Melville's whalemen. He conveys vividly the excitement of the hunt, both of physical prey by contemporary whalemen and his own search for Moby Dick. The islanders know there is a white whale out there. Ahab was not able to destroy him, and the islanders revere and respect him. Severin's vibrant book shows that the whale hunters will surely pass away before Moby Dick, secure in legend and literature, is ever finally caught, or finally known.
