go direct to the great Forum, up the Velabrum, or valley
(once a marsh), right in front of us between the Capitol on the left
and the Palatine on the right. But as we look in the latter direction,
we are attracted by a long low erection almost filling the space
between the Palatine and the Aventine, and turning in that direction
we find ourselves at the lower end of the Circus Maximus, which as
yet is the chief place of amusement of the Roman people. Two famous
shrines, one at each end of it, remind us that we are on historic
ground. At the end where we stand, and where are the _carceres_, the
starting-point for the competing chariots, was the Ara maxima of
Hercules, which prompted Evander to tell the tale of Cacus to his
guest; at the other end was the subterranean altar of Consus the
harvest-god, with which was connected another tale, that of the rape
of the Sabines. All the associations of this quarter point to the
agricultural character of the early Romans; both cattle and harvesting
have their appropriate myth. But nothing is visible here now, except
the pretty little round temple of a later date, which is believed to
have been that of Portunus, the god of the landing-place from the
river.[20]

The Circus, some six hundred yards long, at the time of Cicero was
still mainly a wooden erection in the form of a long parallelogram,
with shops or booths sheltering under its sides; we shall visit it
again when dealing with the public entertainments.[21] Above it on the
right is the Aventine hill, a densely populated quarter of the lower
classes, crowned with the famous temple of Diana, a deity specially
connected with the plebs.[22] The Clivus Patricius led up to this
temple; down this slope, on the last day of his life, Gaius Gracchus
had hurried, to cross the river and meet his murderers in the grove of
Furrina, of which the site has lately been discovered. If we were to
ascend it we should see, on the river-bank below and beyond it,
the warehouses and granaries for storing the corn for the city's
food-supply, which Gracchus had been the first to extend and organise.

But to ascend the Aventine would take us out of our course. Pushing
on to the farther end of the Circus, where the chariots turned at the
_metae_, we may pause a moment, for in front of us is a gate in the
city wall, the Porta Capena, by which most travellers from the south,
using the via Appia or the via Latina, would enter the city.[23]
