The focus of My Antonia is controlled by Jim Burden's attempt to invest the memories of his youth in the image of Antonia. Jim gives us first an extended portrait of the Nebraska prairies, of the Shimerdas' struggle for survival, and of an Antonia who grows muscular under the strain of work. An idyllic quality pervades the narrative, a sense of happiness remembered. Incidents of bitterness and violence are muted by a style which sacrifices immediacy to the afterglow of remembrance. At the midpoint of the novel, Lena Lingrad, enticing, sensually eloquent, poses a challenge to Jim and his memories. A latter-day enchantress, Lena inspires irresponsibility, forgetfulness, and dream. But Jim's narrative is dedicated to showing the value of memory in and for the present; he identifies Antonia with the prairie and clusters its meanings around her. When, after years have passed, he returns to Nebraska and sees Antonia's large, joyous, and vibrant family, the past and the present finally merge for him in a dynamic new image of happiness. Antonia comes to be Jim's personal symbol of the value of human experience. The novel first validates his memory, then transfigures it into something fertile, fresh, and living.
