According to the researchers, the richly decorated vaulted ceilings suggest that Trajan (the 13th Roman emperor) almost certainly came there for the aqueduct's inauguration. The emperor may have been in that area on June 24, 109 A.D., according to historical records. By coincidence O'Neill first explored the aqueduct on June 24, 2009, exactly 1,900 years later. Trajan commemorated the opening of the aqueduct by minting a Roman coin and building a fountain on Janiculum Hill, right where the waters entered the city. The coin shows a river god atop flowing waters, reclining in what looks like a grotto or a tunnel.
The long-sought source of the aqueduct that brought clean fresh water to ancient Rome lies beneath a pig pasture and a ruined chapel near the Italian capital. Aqua Traiana originated around Lake Bracciano, 25 miles from Rome. After collecting water from other springs on its way down to the capital, the channel finally reached Janiculum Hill in Rome, providing clean, drinkable water to the Trastevere district.The team made their discovery between Lake Bracciano and the village of Manziana (about 25 miles northwest of Rome), amid thick vegetation and pig pastures. Much of the site is in urgent need of restoration, most notably being threatened by the roots of a giant fig tree.
