Through the Looking-Glass, and What Alice Found There, written in1871, 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 (4 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, uses frequent changes in time and spatial directions as a plot device, and draws on the imagery of chess. Charles Lutwidge Dodgson (1832 – 1898), better known by his pen name, Lewis Carroll, was an English writer, mathematician, logician, Anglican deacon and photographer.
