Hyperion follows a young American protagonist named Paul Flemming as he travels through Germany. The character's wandering is partially inspired by the death of a friend. The author had also recently lost someone close to him. Longfellow's first wife, Mary Storer Potter, died in Rotterdam in the Netherlands after a miscarriage in 1836; Longfellow was deeply saddened by her death and noted in his diary: "All day I am weary and sad ... and at night I cry myself to sleep like a child."
