The stream is sometimes filled with blood from people killing, stealing, shouting and doing the things historians usually record, while on the banks, unnoticed, people build homes, make love, raise children, sing songs, write poetry and even whittle statues.

After a diligent inquiry, I can discern four principal causes for the ruin of Rome, which continued to operate in a period of more than a thousand years.
