Montesquieu

We have spo­ken of public dis­so­lu­te­ness because it is tied to luxury, which always fol­lows it, and which it always fol­lows. If you leave the move­ments of the heart unbrid­led, how can you rein in fai­lings of the mind ?

In Rome, in addi­tion to the gene­ral ins­ti­tu­tions, the cen­sors had the magis­tra­tes make seve­ral spe­ci­fic laws to keep women fru­gal. Such was the pur­pose of the Fannian, Licinian, and Oppian Laws. We can see in Livy1 how agi­ta­ted the senate was when it cal­led for revo­ca­tion of the Oppian Law. Valerius Maximus fixes the era of Roman luxury at the abro­ga­tion of that law.
