| Anamorphic mirrors produce images that are distorted in
one or more dimensions. On the other hand, a distorted object will produce
an image that is considered normal. In the cut below, from Mrs. Norman
Lockyear's 1877 translation of Amédée Guillemin's The
Forces of Nature, a cylindrical mirror is used to produce an image
of a lute player by reflection in a cylindrical mirror.
The (tarnished) silver cylindrical mirror at the right
is in the Garland Collection of Classical Physics Apparatus at Vanderbilt
University in Nashville. It is unmarked, but a similar mirror from Jules
Duboscq of Paris, from whom Vanderbilt bought a good deal of apparatus
ca. 1875, sold for 30 francs ($6.00) in 1865.
