The notorious 1820 sinking of the whaleship "Essex" inspired Herman Melville's "Moby-Dick," as recounted in Nathaniel Philbrick's bestselling book "In the Heart of the Sea: The Tragedy of the Whaleship Essex"--now a major motion picture. But how exactly did Melville transmute the historic tragedy of the Essex into what is arguably the "Great American Novel"? Here, for the first time, R.D. Madison collects together Melville's personal "library" of whaling and whale-lore into a single volume and presents these primary sources in a way that readers can readily see how a horrific whaling tragedy became a literary masterpiece. But where did "Moby-Dick" begin? Prompted by sailor-author Richard Henry Dana, Jr., Melville supplemented his own firsthand experience as a whaleman in the South Pacific with "libraries" of books that he "swum through" to create his whaling masterpiece. Scholars and lay readers alike have long wondered how he did it, and over the past 60 years, a very tight theory of inspiration and creation has emerged. It is very likely wrong. This volume gathers together for the first time all of the main texts that Melville encountered, including the accounts of the unique sinking of the "Essex" by a sperm whale that provided the climax for "Moby-Dick." Melville scholar R. D. Madison examines what critics have said about Melville's response to the sinking and offers the challenging thesis that Melville did not even begin the book at all until spurred on by Dana in the spring of 1850.
