...he went away, and passing through what was called the house of Tiberius, went down into the forum, to where a gilded column stood, at which all the roads that intersect Italy terminate."
- Plutarch, Life of Galba (XXIV.4)
No one can give you exact directions to Milliarium Aureum (aka the Golden Milestone). Just a few carved marble fragments of the gilded column’s base remain in the Roman Forum, where its original location is somewhat difficult to pinpoint.
All roads lead to Rome.
From there, they created an algorithm to calculate the best route from each point to Rome.
(It beats typing a street address into Google Maps 486,713 times.)
From afar, the resulting map looks like a delicate piece of sea lettuce or an early exploration in neuroanatomy.
Zoom in as tight as you can and things become more traditionally cartographic in appearance, names and spatial relations of cities asserting themselves. A bold line indicates a busy route.
In a nod to map lovers outside of Europe, the mobility-obsessed team came up with another map, this one geared to stateside users.
Do you know which of the United States’ nine Romes you are closest to?
Now you do, from 312,719 distinct starting points.
To help them in their labor, the creative team made good use of the GraphHopper route optimization tool and the Open Street Map wiki. In their own estimation, the project’s outcome is “somewhere between information visualization and data art, unveiling mobility on a very large scale."
