Whether rivers or roads, train tracks or flight paths, the network of lines on a map makes the world seem easily accessible—or overwhelmingly complex. Built, manicured, or hypothetical, these network lines give maps the power to help us imagine moving through the world. They can empower us to set off into an unfamiliar city. They have also emboldened European colonizers to reach farther and farther to conquer and extract. Taken as a whole, a network of lines on a map makes connectivity seem inevitable and permanent. But, as the artists in this section reveal, those lines can never quite escape the evidence of the network’s contingency and frailty.
