AQUEDUCTS AT TIVOLI
TEMPLE OF THE SIBYL AND CASCADES
CASCADES OF THE ANIO
This cascade shews the character of the country through which the aqueducts had to be carried, but the waters of the aqueducts taken out of the river Anio were necessarily confined each within its own specus, here in tunnels, which are carried in a zig-zag course gradually down the hill to the level of the Villa of Hadrian in the valley below.
