Ancient Rome, meet Google Earth!

The geniuses behind Google Earth have taken on a new project: the mapping of ancient Rome. Now visitors to the website can take a virtual 3D tour of the ancient city including such buildings as the Forum and the Colosseum.

"This is another step in creating a virtual time machine," said Bernard Frischer of the University of Virginia, which worked with Google on the Roman reconstruction. "The project is a continuation of five centuries of research by scholars, architects and artists since the Renaissance, who have attempted to restore the ruins of the ancient city with words, maps and images," he said.
