For the past several years, filmmakers Ted and Mike O'Neill have worked with archaeologists Rabun Taylor and Katherine Rinne to discover the remains of the Aqua Traiana, one of ancient Rome's greatest aqueducts. The short film here shows the team scouring the countryside north of Rome, discovering one of the aqueduct's spring houses, identifying construction materials and techniques unique to ancient Roman builders, exploring one of the aqueduct's channels, and pinpointing one of the locations where the remains of the Aqua Traiana were used to help build a Renaissance-era aqueduct that also fed the city's insatiable need for water.
