Flatland: A Romance of Many Dimensions is a satirical novella by the English schoolmaster and clergyman Edwin Abbott Abbott. The story describes a two-dimensional world occupied by geometric figures, where of women are simple line-segments, while men are polygons with various numbers of sides. Written pseudonymous by "A Square", the book used the fictional two-dimensional world of Flatland to comment on the hierarchy of Victorian culture, but the novella's more enduring contribution is its examination of dimensions. This masterpiece of science (and mathematical) fiction is a delightfully unique and highly entertaining satire that has charmed readers for more than 100 years.

Edwin Abbott Abbott FBA was an English schoolmaster, theologian, and Anglican priest, best known as the author of the novella Flatland (1884)
