Did 'all roads lead to Rome'? New study finds other cities in the empire were better connected.

The saying that " all roads lead to Rome " may be famous, but a new study finds it's far from true. Extensive new research of the Roman Empire's road system reveals that several other Roman cities were better connected than the Eternal City was during antiquity.

Major cities like Antioch, Ancyra (modern-day Ankara) and Byzantium in what is now Turkey, as well as Corinth in Greece, were "better located than Rome" for those traveling by land, the team wrote in a paper published Tuesday (Sept. 15) in the journal Nature Communications .

At its height in A.D. 117, the Roman Empire covered almost 2.1 million square miles (5.5 million square kilometers) around the Mediterranean Sea, occupying much of Europe, the Middle East and North Africa, the team noted in the study.

For years, the scientists have been creating a vast digital atlas called " Itiner-e " of nearly 186,000 miles (300,000 kilometers) of Roman roads. For the new study, they calculated how well Roman cities were connected to the road system.

In fact, the empire's "most important intermediary route" by land identified in the study didn't even run through Rome.

"It follows the North African and Levantine coast past Antioch and near Ankara, crosses over to Europe at Constantinople, and moves through the Po Valley and Milan into France," study co-author Tom Brughmans , a professor of classical archaeology at Aarhus University in Denmark, told Live Science in an email.

The other well-connected cities had a bevy of reasons for their numerous roads. For instance, Corinth was better connected to the road network because the roads that ran through it linked the Greek Peloponnesian Peninsula to the rest of Greece, and Ancyra was better connected because it was a vital transportation hub for Anatolia.
