Through the Looking-Glass :

Through the Looking-Glass, and What Alice Found There is a novel published in December 1871 by Lewis Carroll, the pen name of Charles Lutwidge Dodgson, a mathematics lecturer at Christ Church, Oxford. It is the sequel to his Alice's Adventures in Wonderland (1865), in which many of the characters were anthropomorphic playing cards. In this second novel the theme is chess. As in the earlier book, the central figure, Alice, enters a fantastical world, this time by climbing through a large looking-glass into a world that she can see beyond it.
