For individuals who are interested in how Defoe's Robinson Crusoe and other narratives of shipwrecks and castaways influenced antebellum American Culture, Shawn Thomson's The Fortress of American Solitude is useful. More specifically, for Melville scholars, the second, third, and fourth chapters provide some interesting insight into possible readings for how Defoe's novel-and the castaway genre in general-may have influenced Melville's call to sea and the penning of some of his most interesting characters.
