How many dimensions are there, and what do they do to reality? | Aeon Essays

In this terrific essay by Marina Benjamin on the scientific and mathematical quest for ever-more dimensions, she offers this lovely insight into the mind-altering effects that the art of Giotto and Uccello must’ve had on their medieval audience:

By consciously exploring geometric principles, these painters gradually learned how to construct images of objects in three-dimensional space. In the process, they reprogrammed European minds to see space in a Euclidean fashion.

In a very literal fashion, perspectival representation was a form of virtual reality that, like today’s VR games, aimed to give viewers the illusion that they had been transported into geometrically coherent and psychologically convincing other worlds.
