My good friend and former Professor, Bernie Frischer, Ph.D., just announced a game that resulted from his collaboration: Rome 320AD. You can see Bernie giving a brief overview of 4th century Rome in this Kahn Academy Video.
The app follows the lives of four Romans as they travel through the city on a summer day in 320 CE. You can explore 3D, interactive models of the city in high resolution and detail.
The Digital Hadrian’s Villa allows visitors to examine sections of site via plans, images, 360° panoramic views, as well as 3D walkthroughs. It also includes videos and interviews with prominent scholars. This is an amazing, and free, resource for scholars and laypersons interested in Roman history and archaeology!
