Irving followed up this eyewitness account with two works that chart the dramatic and tumultuous history of the early American fur trade, very much in the spirit of James Fenimore Cooper’s Leatherstocking Tales. Astoria (1836) recounts John Jacob Astor’s attempt to establish a commercial empire in the Pacific Northwest. The Adventures of Captain Bonneville (1837) is a lively saga of exploration among the mountains, rivers, and deserts of the Far West. While working closely from original documents, Irving wrote also as a mythologist of the vast spaces traversed by "Sindbads of the wilderness." In these three compelling narratives he opened up a crucial region of the American literary imagination influencing such authors as Poe, Hawthorne, and Melville.
