Rome RebornExplore more photos from the story |
It's a common fantasy—what if you could travel back in time and walk the streets of a bygone city, see the light play over long-vanished rooftops? For some people it's more specific. Bernard Frischer, head of the Institute for Advanced Technology in the Humanities at the University of Virginia, has been imagining ancient Rome since he started studying Latin in eighth grade. "It was the first multicultural empire and city," says Frischer. "We always say the Romans were the Americans of antiquity; it was a society based on merit, where anybody could rise to the top."
In early June, Frischer made the time-travel fantasies of countless armchair classicists come true. At a ceremony on Rome's Capitoline Hill, the city's mayor and a team of American researchers unveiled "Rome Reborn": a full-size, real-time digital model of Rome, circa A.D. 320. The entire city is modeled in three dimensions, and users can "fly" through, and over, the ancient city's winding streets, broad plazas, forums—even its most famous monuments. "It's a true 3-D big screen stereo projection," says Frischer, who organized the project. "It's a real-time model for immersive theaters."
Imperial Rome was the largest city the world had ever seen. At its peak in the fourth century A.D., it was home to more than a million people. Not until the rise of Victorian London in the 1800s did a city surpass its population.
Because of its size and importance, Rome may be one of the most-studied cities in history. The urban center of the classical world was 16 square miles, protected by 11 miles of walls. Its buildings have captivated architects for centuries, and classicists, historians, archaeologists and others have spent entire careers trying to understand how the city functioned.
For academics and researchers, the Rome Reborn model will be a way to test theories about how the city worked and looked back then. Trajan's Column, for example, a 125-foot high monument to the military victories of Emperor Trajan, dominated the center of Trajan's Forum, a square near the center of the city north of the Roman Forum. At a conference in Berlin this spring, Frischer "walked" a rapt audience through virtual walls to show how the column would have been visible from most of the surrounding squares as well.
As the buildings on the screen slide by, a sense of place emerges. The column's height and location was no accident, but a statement of power. "That relationship is more complex than you can represent or explain in a book, but it's very easy to experience in the model," says Dean Abernathy, an architecture professor at the University of Virginia. "This gives you the whole context. The city was a three-dimensional place."
Other researchers are tackling different questions: How would crowds of people have filtered in and out of the Coliseum to watch gladiator games? Would the door of a building open onto a majestic view—or a blind alley?
As new research is developed and tested, it can be added to the model. Conceived as a sort of 21st-century academic journal, the idea is that researchers in fields as diverse as architecture, computer programming, literature, engineering and archaeology can collaborate to add layers of information to the model. Frischer compares it to the "wiki" concept behind the online encyclopedia Wikipedia. "We thought we would create this resource of Rome at its peak and then open it up as a peer-reviewed scholarly journal," he explains. "We'll be able to keep adding to our knowledge in new ways."
