Lewis Carroll (Charles Lutwidge Dodgson)'s "Through the Looking-Glass, and What Alice Found There" (1871) is the sequel to "Alice's Adventures in Wonderland" (1865). In a number of ways it is a kind of mirror image of Wonderland: the first book begins outdoors, in the warm month of May (May 4), uses frequent changes in size as a plot device, and draws on the imagery of playing cards; the second opens indoors on a snowy, wintry night exactly six months later, on November 4 (the day before Guy Fawkes Night), uses frequent changes in time and spatial directions as a plot device, and draws on the imagery of chess. In it, there are many mirror themes, including opposites, time running backwards, and so on.
