Upside Down Maps
Perspective drawing, originally perceived as an objective and "scientific" method to depict reality, is in fact an abstraction that utilizes convincing mathematical equations to manipulate an image.
M.C. Escher subjects the laws of perspective to a critical scrutiny by proposing new mathematical relationships and illustrating his discoveries. Escher suggests that three dimensions in flat picture representations can be taken to such lengths that worlds that can not exist in three-dimensional space, can be "mathematically" represented on a flat surface.
His prints are very realistic images that at first glance can be perceived as truthful, but a closer look reveals inconsistencies with reality but not with the mathematical projection.
