"Nature's the same as Rome, was reflected in it"

Nature's the same as Rome, was reflected in it.
We see images of its civic might
In the clear air, as in the sky-blue circus,
In the forum of fields, the colonnade of the grove.
Nature is the same as Rome, again it seems
We have no reason to trouble the gods.
We've got the viscera of the sacrifices
To tell the fortunes of war, and slaves
To keep the silence, and stones with which to build.
