An international research team led by Adam Pažout of Aarhus University has found that Rome was not the actual center of the Roman Empire's road network. By modeling the system based on travel time rather than physical distance, the study challenges the historical significance of the Milliarium Aureum.
Why it matters
This research re-evaluates the structural logic of ancient infrastructure by shifting the metric of centrality from static geography to functional travel time. It highlights how imperial power centers, such as Constantinople after the fourth century, functioned within a broader, more distributed network than traditional models suggested.
The team modeled the Roman road network as a system of nodes and intersections using existing historical data. By calculating travel time between locations, the analysis demonstrates that Rome's mathematical centrality was less significant than previously assumed.

The details
Researchers treated the Roman Empire's infrastructure as a network graph, where roads functioned as connections and intersections served as stops. They used travel time to determine accessibility rather than simple physical distance from the capital. This approach moves beyond the historical assumption that the Milliarium Aureum—a monument built in the late first century BCE to measure distances—functioned as the literal center of gravity for empire-wide transit.
Timeline
Late first century BCE: Emperor Augustus built the Milliarium Aureum in Rome.
After fourth century CE: Constantinople became the imperial capital.
The Tech Race
This study departs from traditional cartographic models that, like the 16th-century Mercator map design, favor a specific visual or political center. It aligns with modern network science approaches that prioritize functional access over symbolic geometry.
This research provides a new framework for historians and data scientists to evaluate ancient logistical systems using modern computational tools. It replaces the static, Rome-centric view of antiquity with a dynamic model that accounts for shifting capitals like Constantinople.
The takeaway
The study confirms that Roman connectivity was a functional network rather than a hub-and-spoke system radiating solely from the Forum. Researchers can now apply this travel-time metric to other complex historical transit systems to further map ancient resource flows.
