They were apparent or latter, which sometimes traversed considerable space, and werecarried through rocks, contained pipes (fistulse, tubuli) of lead orterra cotta, frequently marked either with the name of the potter, orthe name of the consuls in whose time they were laid down. At con-venient points, in ihe course of these aqueducts, as it was necessaryfrom the water being conveyed through pipes, there were reservoirs(piscinae), in which the water might deposit any sediment that itcontained. Vitruvius has given rules for the laying down of pipes,and for forming reservoirs. The apparent aqueducts were built onthe most stupendous scale. Hills were pierced through by tunnels,and valleys crossed either by solid substructions or arches ofmasonry, according to the height required, bringing water fromsources varying from thirty to sixty miles in distance. At one. AQUEDUCT. period of the history of Rome no less than twenty aqueducts stretchedtheir long line of arches, and brought as many different streams ofwater, across the wide plain or Campagna in which the city the most part they were built of brick, and consisted of nearlysquare piers running up to the same height—a slight and uniformdeclivity being necessarily maintained—and connected by semicir-cular arches, over which the conduit (specus, canalis) ran. Thisconduit had a paved or tiled floor, and was enclosed laterally bywalls of brick or stone, and with a transverse arch, or by a simple AQUEDUCTS. 91 flat coping of stone. The water either ran directly through thisconduit, or was carried through pipes laid along its floor. Theseaqueducts were either simple, double or triple, according as theywere composed of a single, two or three tiers of arches. At thetermination of the aqueduct, within the city, was a vast r
