At Mainz are the ruins of an aqueduct 7000 yds. long, about half of
which is carried on from 500 to 600 pillars (_Archaeological Journal_,
xlvii., 1890, pp. 211-214). This aqueduct was built by the XIVth legion
and was for the use of the camp, not for the townspeople. For the
similar aqueduct at Luynes see _Arch. Journ._ xlv. (1888), pp. 235-237.
Similar witnesses of Roman occupation are to be seen in Dacia, Africa
(see especially under CARTHAGE), Greece and Asia Minor. (4) The aqueduct
at Jouy-aux-Arches, near Metz, which originally extended across the
Moselle, here very broad, conveyed to the city an abundance of excellent
water from Gorze. From a large reservoir at the source of the aqueduct
the water passed along subterranean channels built of hewn stone, and
sufficiently spacious for a man to walk in them upright. Similar
channels received the water after it had crossed the Moselle by this
bridge, at the distance of about 6 m. from Metz, and conveyed it to the
city. The bridge consisted of only one row of arches nearly 60 ft. high.
The middle arches have given way under the force of the water, but the
others are still perfectly solid. This aqueduct is probably to be
attributed to the latter half of the 4th century A.D. It is for the use
of the town; hence its size. (5) One of the principal bridges of the
aqueduct of Antioch in Syria is 700 ft. long, and at the deepest point
200 ft. high. The lower part consists almost entirely of solid wall, and
the upper part of a series of arches with very massive pillars. The
masonry and design are rude. The water supply was drawn from several
springs at a place called Beit el-Ma (anc. Daphne) about 4 or 5 m. from
Antioch. From these separate springs the water was conducted by channels
of hewn stone into a main channel, similarly constructed, which
traversed the rest of the distance, being carried across streams and
valleys by means of arches or bridges. (6) At the village of Moris,
about an hour's distance north-west from the town of Mytilene, is the
bridge of an aqueduct, carried by massive pillars built of large hewn
blocks of grey marble, and connected by means of three rows of arches,
of which the uppermost is of brick. The bridge extended about 500 ft. in
length, and at the deepest point was from 70 to 80 ft. high. Judged by
the masonry and the graceful design, it has been thought to be a work of
the age of Augustus. Remains of this aqueduct are to be
