Inscribed in Latin, this stone identifying the builders of a section of the high-level aqueduct was found on the western channel of this aqueduct. It reads, “A detachment of Legion Ten Fretensis [dedicates its work] to Emperor Trajan Hadrian Augustus.” Additional inscriptions naming the sixth and second Roman legions were found in other sections of the western aqueduct. It is likely that Roman soldiers serving Hadrian in about 130 A.D. were assigned to public works projects, such as building this additional 6 ½-mile-long western channel next to the existing eastern channel—a useful distraction for restless legionnaires.
