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 (a mirror) into a world that she can see beyond it. There she finds that, just as in a reflection, things are reversed, including logic (for example, running helps one remain stationary, walking away from something brings one towards it, chessmen are alive and nursery-rhyme characters are real).
Among the characters Alice meets are the severe Red Queen, the gentle and flustered White Queen, the quarrelsome twins Tweedledum and Tweedledee, the rude and opinionated Humpty Dumpty, and the kindly but impractical White Knight. Eventually, as in the earlier book, after a succession of strange adventures, Alice wakes and realises she has been dreaming. As in Alice's Adventures in Wonderland, the original illustrations are by John Tenniel.
