Edwin A. Abbott

Classic of science (and mathematical) fiction — charmingly illustrated by author — describes the journeys of A. Square and his adventures in Spaceland (three dimensions), Lineland (one dimension) and Pointland (no dimensions). A. Square also entertains thoughts of visiting a land of four dimensions — a revolutionary idea for which he is banished from Spaceland.

In the first work, A. Square meets a tragic fate when he dares to inform the inhabitants of his two-dimensional universe that there is a third and fourth dimension, and in the second work, an inhabitant of a two-dimensional world discovers curved surfaces.
