Fields of vision. 19th century diagrams showing how the field of view maps to the retinas of different eyes. At top left is a bird's eye, at centre left is a simple eye and at bottom left is a fly's eye. At right the differences between a concave (top) and faceted (bottom) retina are shown. Artwork from 'Contributions to the Physiology of Vision' (1834) by the German physician Carl Moritz Nicolaus Bartels (1800-1835).
