New Study Challenges "All Roads Lead to Rome" Saying
Research indicates Constantinople, not Rome, was a more central hub for overland travel in the Roman Empire.
A new study analyzing nearly 190,000 miles of Roman roads suggests that the popular adage "All roads lead to Rome" may not fully reflect the empire's transportation network. The research, published in Nature Communications, indicates that Constantinople, now Istanbul, emerged as a more significant hub for overland travel, particularly after it became the imperial capital in the fourth century A.D.
Researchers from Aarhus University in Denmark created a comprehensive map of the Roman road network spanning Europe, the Middle East, and North Africa. Their analysis revealed that provincial capitals played crucial roles in overland transit, challenging the singular focus on Rome as the ultimate destination.
Tom Brughmans, the study's lead researcher and a classical archaeologist, noted that the proverb, which he described as medieval in origin, should not be interpreted literally. He pointed out that roads in Roman Britain, for instance, did not actually lead to Rome. "It is quite surprising how persistently this maxim has shaped popular understanding of Roman roads," Brughmans said. "It’s fair to say our study complicates the proverb. I prefer to say, ‘All roads lead to Rome and everywhere else.'"
Taco Terpstra, a professor of history and classics at Northwestern University, who was not involved in the study, acknowledged that Constantinople became a major hub after it was established as the capital. However, he emphasized that Rome remained the undisputed center of political, military, and ideological power for centuries. "Rome is the center of the empire. This is where power lies," Terpstra stated, noting that Rome was the largest city in the empire with approximately one million inhabitants, significantly more than other major cities like Alexandria.
The study also touched upon the engineering of Roman roads, often characterized by their straightness. Terpstra explained that these roads were built as straight as technological limitations and terrain allowed. Initially constructed for military purposes to facilitate rapid troop movement through conquered territories, they later evolved to serve economic functions.
Despite the extensive road network, Terpstra highlighted that maritime transportation was the primary means of transit across the Roman Empire due to its cost-effectiveness for moving goods. "The main transportation network of the Roman Empire is maritime," he said. "That is really where the major connectivity lies."
