Ponte Vittorio Emanuele II across the Tiber River in Rome (Italy)

Now conquering Rome doth conquered Rome inter,

And she the vanquished is, and vanquisher.
To show us where she stood there rests alone
Tiber; and that too hastens to be gone.
Learn, hence what fortune can. Towns glide away;
And rivers, which are still in motion, stay.

Joachim du Bellay
