This is incredible news for anybody interested in ancient history.
The Lupercale is legendary in more than one way. For the ancient Romans it was the cave under the Palatine hill where the shewolf (lupa) suckled the two abandoned twins Romulus and Remus. Romulus and Remus then grew up and founded the city of Rome on April 21st, 753 BC. In a fight over leadership Romulus then killed Remus, and the city was henceforth called Rome after Romulus who became the first King of Rome. The Lupercale was therefore considered the very birthplace of Rome and was considered a sacred site.
