In a short story called “Tlon, Uqbar, Orbis Tertius,” Jorge Luis Borges describes the discovery of a strange book. Written in an arcane language, the book seems to be one volume of an encyclopedia of another world, intriguingly unlike the world of everyday reality. The world of the volume rapidly becomes a universal obsession: scholarly journals were devoted to it, people begin to dress and act in ways suggested by the volume. So compelling are the glimpses of the world revealed by the volume that its reality finally crowds out our own, and the world becomes the world of Tlon.
The volume you are holding in your hands is the volume Borges had in mind.
