Taking technological developments in urban mapping and the megacity phenomena of rapid change and sprawling space as its starting point, this essay provides a history of the present through a genealogy of maps of Montpellier in France, a rapidly growing modern city that provides examples from the earliest printed maps of the 16th century through to the most recent innovations in public-sponsored 3D mapping. By tracing the shifting correlations of narrative elements, it places in historical perspective the relationship between those (...) concepts, such as verticality and horizontality, and perception and representation, which are problematized in the contemporary contexts of megacities and digital technology.
