Ab urbe condita

There is this exceptionally beneficial and fruitful advantage to be derived from the study of the past, that you see, set in the clear light of historical truth, examples of every possible type. From these you may select for yourself and your country what to imitate, and also what, as being mischievous in its inception and disastrous in its issues, you are to avoid.

Unless, however, I am misled by affection for my undertaking, there has never existed any commonwealth greater in power, with a purer morality, or more fertile in good examples; or any state in which avarice and luxury have been so late in making their inroads, or poverty and frugality so highly and continuously honoured, showing so clearly that the less wealth men possessed the less they coveted.

In these latter years wealth has brought avarice in its train, and the unlimited command of pleasure has created in men a passion for ruining themselves and everything else through self-indulgence and licentiousness. But criticisms which will be unwelcome, even when perhaps necessary, must not appear in the commencement at all events of this extensive work.
