Lydia Huntley Sigourney (1791-1865) was the most widely read and respected pre-Civil War American woman poet in the English-speaking world. In a half-century career, Sigourney produced a wide range of poetry and prose envisaging the United States as a new kind of republic with a unique mission in history, in which women like herself had a central role. This edition contributes to the current recovery of Sigourney and her republican vision from the oblivion into which they were cast by the aftermath of the Civil War, the construction of a male-dominated American "national" literary canon, and the aesthetics of Modernism. In this Broadview edition, a representative selection of poetry and prose from across her career illustrates Sigourney's national vision and the diversity of forms she used to promote it. In the appendices, letters and documents illustrate her challenges and working methods in what she called her "kitchen in Parnassus."
