Cylindrical Mirror
   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.
