tonantem credidimus Jovem Regnare.--Hor. 1. iii. Ode 5.

We shall find this temple mentioned again in c. xci. of the life of
Augustus.]

[Footnote 155: The Portico of Octavia stood between the Flaminian circus
and the theatre of Marcellus, enclosing the temples of Jupiter and Juno,
said to have been built in the time of the republic. Several remains of
them exist, in the Pescheria or fish-market; they were of the Corinthian
order, and have been traced and engraved by Piranesi.]

[Footnote 156: The magnificent theatre of Marcellus was built on the site
where Suetonius has before informed us that Julius Caesar intended to
erect one (p. 30). It stood between the portico of Octavia and the hill
of the Capitol. Augustus gave it the name of his nephew Marcellus, though
he was then dead. Its ruins are still to be seen in the Piazza Montanara,
where the Orsini family have a palace erected on the site.]

[Footnote 157: The theatre of Balbus was the third of the three permanent

mentioned.]

[Footnote 158: Among these were, at least, the noble portico, if not the

Agrippa also built the temple of Neptune, and the portico of the
Argonauts.]

[Footnote 159: To whatever extent Augustus may have cleared out the bed

ruins and mud has been constantly going on. Not many years ago, a scheme
was set on foot for clearing it by private enterprise, principally for the
sake of the valuable remains of art which it is supposed to contain.]

[Footnote 160: The Via Flaminia was probably undertaken by the censor
Caius Flaminius, and finished by his son of the same name, who was consul
A.U.C. 566, and employed his soldiers in forming it after subduing the
Ligurians. It led from the Flumentan gate, now the Porta del Popolo,
through Etruria and Umbria into the Cisalpine Gaul, ending at Ariminum,
the frontier town of the territories of the republic, now Rimini, on the
Adriatic; and is travelled by every tourist who takes the route, north of
the Appenines, through the States of the Church, to Rome. Every one knows
that the great highways, not only in Italy but in the provinces, were
among the most magnificent and endu
