Although attacks by whales on whalers were not at all common, there were instances, of which Melville was aware. One was the sinking of the
Nantucket whaler Essex in 1820, after a large
sperm whale rammed her 2,000 miles (3,200 km) from the western coast of South America. First mate
Owen Chase, one of eight survivors, recorded the events in his 1821
Narrative of the Most Extraordinary and Distressing Shipwreck of the Whale-Ship Essex. The other event was the alleged killing in the late 1830s of the
albino sperm whale
Mocha Dick, in the waters off the
Chilean island of
Mocha. Mocha Dick was rumored to have nineteen harpoons in his back from other whalers, and appeared to attack ships with premeditated ferocity. One of his battles with a whaler served as the subject for an article by explorer
Jeremiah N. Reynolds in the May 1839 issue of
The Knickerbocker or New-York Monthly Magazine. Melville was familiar with the article, which described: Mocha Dick had over 100 encounters with whalers in the decades between 1810 and the 1830s. He was described as being gigantic and covered in
barnacles. Although he was the most famous, Mocha Dick was not the only white whale in the sea nor the only whale to attack hunters. While an accidental collision with a sperm whale at night accounted for sinking of the
Union in 1807, it was not until August 1851 that the whaler
Ann Alexander, while hunting in the Pacific off the
Galapagos Islands, became the second vessel since
Essex to be attacked, holed and sunk by a whale. Melville remarked: :Ye Gods! What a commentator is this
Ann Alexander whale. What he has to say is short & pithy & very much to the point. I wonder if my evil art has raised this monster. ==Symbolism==
