In 1840, astronomers knew an awful lot about the movements of celestial bodies, but they still lacked photographs. In that year, Charles F. Blunt published a very popular illustrated book The Beauty of the Heavens : a Pictorial Display of the Astronomical Phenomena of the Universe. It contained over a hundred illustrations printed by the then-new process of lithography. See a sampling of the pictures and some of the text as well at BibliOdyssey. Link
