In order to present the tale as an authentic exploration, Poe used a number of the travel journals that proliferated at the time he was writing the novel. Poe's most significant source was the explorer Jeremiah N. Reynolds, whose work "Address on the Subject of a Surveying and Exploring Expedition to the Pacific Ocean and the South Seas" was reviewed favorably by Poe in January 1837. Poe used about 700 words of Reynolds' address in Chapter XVI, almost half the length of the chapter. In 1843, Poe also praised Reynolds in a review of "A Brief Account of the Discoveries and Results of the United States' Exploring Expedition" printed in "Graham's Magazine". It is unclear whether Poe and Reynolds ever met, but legend has it that shortly before Poe's mysterious death, in his delirium Poe called out the name "Reynolds"; though the incident is possibly apocryphal, one theory says Poe meant Jeremiah Reynolds, reflecting the explorer's influence.
