He has a dream about a one-dimensional world of lustrous points called Lineland. He trys to convince the Lineland King of a second dimension but it is impossible for the King to see outside of his straight line. A Sphere visits Flatland once each millennium to train a new apostle of the existence of Spaceland a three dimensional world. The Square cannot comprehend a third dimension until he sees Spaceland for himself. From Spaceland, they observe the leaders of Flatland acknowledging the existence of the sphere and prescribing the silencing of anyone found telling about Spaceland and the third dimension.
