Louisa May Alcott, who wrote Little Women, in which there is a chapter titled "Castles in the Air." She wrote, "...silvery white peaks, that shone like the airy spires of some Celestial City." Speaking of Concord, where Emerson and Hawthorne also lived, we also would have found in Concord at that time, Henry David Thoreau and his friend William Ellery Channing Jr. Sweeney [1989] has pointed out anthropomorphic images in Thoreau's writing.
