Lewis Carroll 
Through the Looking-Glass 

Through the Looking-Glass is a novel by Lewis Carroll, the sequel to Alice’s Adventures in Wonderland. 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, 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 4 November (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.Whereas the first book has the deck of cards as a theme, this book is based on a game of chess, played on a giant chessboard with fields for squares. Most main characters in the story are represented by a chess piece or animals, with Alice herself being a pawn. The looking-glass world is divided into sections by brooks or streams, with the crossing of each brook usually signifying a notable change in the scene and action of the story: the brooks represent the divisions between squares on the chessboard, and Alice’s crossing of them signifies advancing of her piece one square.
