Through the Looking-Glass

Through the Looking-Glass, and What Alice Found There by Lewis Carroll (1871)

Alice steps through a mirror into a world where everything is reversed — a giant chess game where she must become a queen. Featuring Tweedledee and Tweedledum, the Jabberwocky, Humpty Dumpty, and the Red Queen's race where you must run just to stay in place.

Historical Significance:
Carroll's sequel to Alice's Adventures in Wonderland was published in December 1871, again illustrated by John Tenniel. While the first Alice book was pure nonsense, Looking-Glass has a more structured plot — based on an actual chess game that can be played out on a board. Carroll, a mathematics lecturer at Oxford, embedded logical puzzles and wordplay that continue to delight mathematicians.

The Jabberwocky poem ("'Twas brillig, and the slithy toves") is the most famous nonsense poem in English. Humpty Dumpty's declaration that "When I use a word, it means just what I choose it to mean" has been cited in Supreme Court decisions and philosophy papers. The Red Queen's hypothesis in evolutionary biology takes its name from this book.
