NOW AN INTERACTIVE MAP ALLOWS YOU TRAVEL THROUGH ANCIENT ROME JUST THE WAY HADRIAN AND ANTINOUS DID
Now a new online tool, made by a team of historians and information technology specialists at Stanford University, shows just how long and costly it was to send people and cargo between cities in the Roman Empire.
"It's Google Maps for the ancient world, complete with the 'Avoid Highways' feature,” Scott Weingart, a doctoral student in library sciences at the University of Indiana, wrote in a blog-post review. Weingart was not involved in creating the tool, called ORBIS, but its creators asked him to preview and comment on it. His review appeared May 4 in the Editor's Choice column in Digital Humanities Now.
A paper map can show how far two cities are from one another, but in a world of sailing ships and donkey trains, the shortest route wasn't necessarily the one people would use -- certainly not an Imperial Entourage consisting of hundreds of people. ORBIS shows likely routes based on conditions 2,000 years ago.
The ORBIS team used ancient maps and records, modern-day weather measurements and modern-day historians' experiments with trying to sail in Roman-style ships to inform their calculations.
ORBIS helps historians see how the Roman Empire was shaped by the time and cost of moving people and goods between cities, according to the ORBIS website. Cities on the edges of the empire were very expensive to ship to, for example, even if they weren’t necessarily that far away.
The results also show how much it would have cost to travel or to ship a kilogram of wheat that distance, at that time of year. For example, the fastest possible July trip between Rome and Londinium – or modern-day London – would have taken 27 days. (The same trip now takes less than three hours by plane.) It would have cost a merchant 7.92 denarii, a late Roman currency, to send a kilogram of wheat by donkey that distance. For a person to travel the route, he would have to pay 900.93 denarii.
Users can make infinite adjustments, looking for the cheapest passenger route, for example, or for a route entirely on land. They can choose at what speed they’ll travel, specifying whether they want to go at a "rapid military march," on an "ox cart" or in a "camel caravan." As yet there is no option for "Emperor's Sedan Chair" or "Imperial Barge."
