This plate depicts a prominent mathematical and optical instrument, George Adams’ camera obscura model of vision, as well as several optical experiments proposed in the book. Of particular interest to this gallery is fig. 7 in the lower left-hand of the print, which is a depiction of one of Adams’s optical instruments—the artificial eye. Though not mechanical, the artificial eye can be tied to theories of automata in that it both simulates bodily processes and calls attention to the limits of simulation and mechanization.
