"The white marble Peace Monument was erected in 1877-1878 to commemorate the naval deaths at sea during the Civil War. ... the symbols of science, literature, and art (including an angle, a gear, a book, and a pair of dividers) signify the progress of civilization that peace makes possible." -- The Peace Monument.
