A cross-institutional team has built a a simulation of Rome as it was in 320 A.D. called Rome Reborn 1.0.
Here’s an excerpt from the press release:
Rome’s Mayor Walter Veltroni will officiate at the first public viewing of "Rome Reborn 1.0," a 10-year project based at the University of Virginia and begun at the University of California, Los Angeles (UCLA) to use advanced technology to digitally rebuild ancient Rome. The event will take place at 2 p.m. in the Palazzo Senatorio on the Campidoglio. An international team of archaeologists, architects and computer specialists from Italy, the United States, Britain and Germany employed the same high-tech tools used for simulating contemporary cities such as laser scanners and virtual reality to build the biggest, most complete simulation of an historic city ever created. "Rome Reborn 1.0" shows almost the entire city within the 13-mile-long Aurelian Walls as it appeared in A.D. 320. At that time Rome was the multicultural capital of the western world and had reached the peak of its development with an estimated population of one million.
"Rome Reborn 1.0" is a true 3D model that runs in real time. Users can navigate through the model with complete freedom, moving up, down, left and right at will. They can enter important public buildings such as the Roman Senate House, the Colosseum, or the Temple of Venus and Rome, the ancient city’s largest place of worship.
As new discoveries are made, "Rome Reborn 1.0" can be easily updated to reflect the latest knowledge about the ancient city. In future releases, the "Rome Reborn" project will include other phases in the evolution of the city from the late Bronze Age in the 10th century B.C. to the Gothic Wars in the 6th century A.D. Video clips and still images of "Rome Reborn 1.0" can be viewed at www.romereborn.virginia.edu. . . .
The "Rome Reborn" project was begun at UCLA in 1996 by professors Favro and Frischer. They collaborated with UCLA students from classics, architecture and urban design who fashioned the digital models with continuous advice from expert archaeologists. As the project evolved, it became collaborative at an international scale. In 2004, the project moved its administrative home to the University of Virginia, while work in progress continued at UCLA. In the same year, a cooperative research agreement was signed with the Politecnico di Milano. . . .
Many individuals and institutions contributed to "Rome Reborn" including the Politecnico di Milano (http://www.polimi.it), UCLA (http://www.etc.ucla.edu/), and the University of Virginia (www.iath.virginia.edu). The advisors of the project included scholars from the Italian Ministry of Culture, the Museum of Roman Civilization (Rome), Bath University, Bryn Mawr College, the Consiglio Nazionale delle Ricerche, the German Archaeological Institute, Ohio University, UCLA, the University of Florence, the University of Lecce, the University of Rome ("La Sapienza"), the University of Virginia and the Vatican Museums.
