Which is why Melville's Marginalia Online is so fascinating. A scholar is using digital technology to bring Melville's erased notations (.pdf) from his personal copy of Thomas Beale's 1839 The Natural History of the Sperm Whale back to light. From the February 17th Chronicle of Higher Education:
Imagine, at the end of Herman Melville's Moby-Dick, that Captain Ahab and the crew of the Pequod kill the white whale instead of the other way around. That Ishmael is not alone in his escape. Steven Olsen-Smith, an associate professor of English at Boise State University, has reconstructed textual evidence that strongly suggests that Melville, whose 1851 novel stands as one of the great achievements of American literature and an enduring study of doomed monomania, entertained just such a scenario.
I was slightly disappointed to discover that the presentation is delivered as a mocked-up, generic image of Beale's book, with the notes themselves as digital recreations, a sort of marginal CGI.
It does make me wonder what Reed might have done with this new information, considering he chose to have Ishmael perish with the rest of the ship's crew for his 1947 BBC radio adaptation.
