                                Diagrams relating to anamorphosis. They show how to transfer an image (at the top called 'archetypus') onto a half circle (at the bottom) using a grid ('rete'), so that it would reflect the image correctly onto a cylindrical mirror placed at the centre of the half circle. Anamorphosis had been of interest to artists since the sixteenth century and the various rules for creating anamorphic images may be found, for example, in Jean-François Nicéron's Thaumaturgus opticus, sive amiranda optices (1646).
