A Square lives in a two-dimensional world where women are lines, soldiers are triangles and priests are circles, and where the number of your sides decides your rank. Nobody there has ever heard of height. One evening, a Sphere from elsewhere passes through his house and shows him what no inhabitant of his world can conceive.
Behind the mathematical fable lies a very funny satire of Victorian England and its prejudices. The book has also given generations of readers, and the astronomer Carl Sagan, the best way to picture a fourth dimension.
Short, clear and mischievous, this little classic is a pleasure to read in the language you are learning, with the author's drawings and the translation always before your eyes.
