The Song of Hiawatha is an 1855 epic poem, in trochaic tetrameter, by Henry Wadsworth Longfellow, featuring a Native American hero. Longfellow's sources for the legends and ethnography found in his poem were the Ojibwe Chief Kahge-ga-gah-bowh during his visits at Longfellow's home; Black Hawk and other Sac and Fox Indians Longfellow encountered on Boston Common; Algic Researches (1839) and additional writings by Henry Rowe Schoolcraft, an ethnographer and United States Indian agent; and Heckewelder's Narratives. In sentiment, scope, overall conception, and many particulars, Longfellow's poem is a work of American Romantic literature, not a representation of Native American oral tradition. Longfellow insisted, "I can give chapter and verse for these legends. Their chief value is that they are Indian legends."
