seful vehicle
instead of their more cumbrous RHEDA, not only for journeys where
dispatch was required, but in solemn processions, and for ordinary
purposes. They seem to have become the fashion, for Ovid tells us that
these little carriages were driven by young ladies, themselves holding
the reins, Amor. xi. 16. 49.

[418] Suetonius flourished about seventy years after this, in the reign
of Adrian, and derived many of the anecdotes which give interest to his
history from cotemporary persons. See CLAUDIUS, c. xv. etc.

[420] This aqueduct, commenced by Caligula and completed by Claudian, a
truly imperial work, conveyed the waters of two streams to Rome,
following the valley of the Anio from above Tivoli. The course of one of
these rivulets was forty miles, and it was carried on arches, immediately
after quitting its source, for a distance of three miles. The other, the
Anio Novus, also began on arches, which continued for upwards of twelve
miles. After this, both were conveyed under ground; but at the distance
of six miles from the city, they were united, and carried upon arches all
the rest of the way. This is the most perfect of all the ancient
aqueducts; and it has been repaired, so as to convey the Acqua Felice,
one of the three streams which now supply Rome. See CLAUDIUS, c. xx.

[421] By Septa, Suetonius here means the huts or barracks of the
pretorian camp, which was a permanent and fortified station. It stood to
the east of the Viminal and Quirinal hills, between the present Porta Pia
and S. Lorenzo, where there is a quadrangular projection in the city
walls marking the site. The remains of the Amphitheatrum Castrense stand
between the Porta Maggiore and S. Giovanni, formerly without the ancient
walls, but now included in the line. It is all of brick, even the
Corinthian pillars, and seems to have been but a rude structure, suited
to the purpose for which it was built, the amusement of the soldiers, and
gymnastic exercises. For this purpose they were used to construct
temporary amphitheatres near the stations in the distant provinces, which
were not built of stone or brick, but hollow circular spots dug in the
ground, round which the spectators sat on the declivity, on ranges of
seats cut in the sod. Many vestiges of this kind have been traced in
Britain.
