AQUEDUCTS. 91
flat coping of stone. The water either ran directly through this
conduit, or was carried through pipes kid along its floor. These
aqueducts were either simple, double or triple, according as they
were composed of a single, two or three tiers of arches. At the
termination of the aqueduct, within the city, was a vast reservoir
called castellum, which formed the head of the water, from which it
was conducted through pipes into smaller reservoirs, and thence
was distributed through the city, thus supplying the public foun-
tains, baths, and houses. The chief castellum was, externally, a
highly decorated building. The so-called trophies of Marius, at
Rome, are supposed by Tiranesi to have been a castellum or reservoir
of the Aqua Julia. Excavations made some years ago seem to con-
firm his opinion. Remains of works of art found near it prove that
it must have had a very ornamental exterior.
We shall begin our enumeration of the principal aqueducts by
the most ancient aqueducts in Rome. Before the year of Rome, 4-11,
the city was supplied with water from the Tiber only. In that year
(li.c. 313) Appius Claudius, the censor, constructed an aqueduct
which brought water from a distance of seven miles; it was called
Aqua Appia, after him. It began to the left of the Via Prsenestina ;
and, according to Frontinus, its whole course, except sixty paces
near the Porta Caprena, was under ground. This last portion was
on arches. No traces of it remain.
The Anio Yetus was constructed by Marcus Curius Dentatus,
B c. 272, and was finished by M. Fulvius Flaccus. The water was
derived from a source of the river Anio, near Augusta, twenty miles
beyond Tibur, and about forty-three from Rome. It was of peperino
stone. A small portion of this aqueduct is still visible outside the
Porta Maggiore.
The Aqua Marcia was constructed by the prator, Q. Marcus Rex,
by command of the senate, B.C. 144. It had its source in a small
stieam which runs into the Anio, not far from the present town of
Subiaco, about thirty-seven miles from Pome. It was repaired by
Agrippa. The latter portion of this aqueduct for about six mile's
from Pome was on arches, the remains of which form one of the
most interesting features of the Roman Campagna. It is remarkable
for the excellence and wholesomeness of its water.
The Aqua Tepula was constructed by Cneus Ssrvilius Ceepio a
L. Cassius Longinus, B.C. 126. It had its source near the tenth mi
stone on the Via Latina.
