Flatland

Origin
Edwin Abbott Abbott's Flatland: A Romance of Many Dimensions is a satirical novella published in 1884. The story describes a two-dimensional world occupied by geometric figures. This means that women are simple line-segments, while men are polygons with various numbers of sides. The narrator of the story simple goes by Square, who is literally a square, a member of the castle of gentlemen and professionals. The first half of the story goes through the practicalities of existing in a world that is two-dimensional as well as history leading up to the year 1999. Like many stories of the time Square starts to dream of a different type of world out there, like a one-dimensional world. To further excite himself Square meets a three-dimensional sphere, named Sphere, who comes to Flatland to find a new apostle who knows and can visit all the worlds, one-dimension is Lineland, two is Flatland and three is Spaceland. Once square becomes that apostle he attempts to convince Sphere of fourth, fifth, sixth, etc. dimensions. Due to Sphere thinking even that is too radical Square is returned to Flatland in disgrace.
