Flatland: A Romance of Many Dimensions is a satirical novella by the English theologian, Anglican priest and schoolmaster Edwin Abbott Abbott, first published in 1884 by Seeley & Co. of London. Written pseudonymously by "A Square", the book used the fictional two-dimensional world of Flatland to satirise the class and gender hierarchies of Victorian society, but the novella's more enduring contribution is its examination of dimensions.
