Through the Looking-Glass, and What Alice Found There (1871) is a work of childrens literature by Lewis Carroll (Charles Lutwidge Dodgson), generally categorized in the fairy tale genre.[citation needed] It is the sequel to Alices Adventures in Wonderland (1865). Although it makes no reference to the events in the earlier book, the themes and settings of Through the Looking-Glass make it 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.
