citizens of Pisa, whom he caused to stand aside while he conversed with the Florentines.  From all which circumstances his duplicity might have been suspected, since, had he meant to do as he had engaged, it was most unlikely that he should be negotiating so openly.  But the desire to recover possession of Pisa so blinded the Florentines that they allowed themselves to be conducted under his guidance to the Lucca Gate, where, through his treachery, but to their own disgrace, they lost a large number of their men and officers.

CHAPTER XLIX.—­That a Commonwealth to preserve its Freedom has constant need of new Ordinances.  Of the services in respect of which Quintius Fabius received the surname of Maximus.

It must happen, as I have already said, in every great city, that disorders needing the care of the physician continually spring up; and the graver these disorders are, the greater will be the skill needed for their treatment.  And if ever in any city, most assuredly in Rome, we see these disorders assume strange and unexpected shapes.  As when it appeared that all the Roman wives had conspired to murder their husbands, many of them being found to have actually administered poison, and many others to have drugs in readiness for the purpose.

Of like nature was the conspiracy of the Bacchanals, discovered at the time of the Macedonian war, wherein many thousands, both men and women, were implicated, and which, had it not been found out, or had the Romans not been accustomed to deal with large bodies of offenders, must have proved perilous for their city.  And, indeed, if the greatness of the Roman Republic were not declared by countless other signs, as well as by the manner in which it caused its laws to be observed, it might be seen in the character of the punishments which it inflicted against wrong-doers.  For in vindicating justice, it would not scruple or hesitate to put a whole legion to death, to depopulate an entire city, or send eight or ten thousand men at a time into banishment, subject to the most stringent conditions, which had to be observed, not by one of these exiles only, but by all.  As in the case of those soldiers who fought unsuccessfully at Cannae, who were banished to Sicily, subject to the condition that they should not harbour in towns, and should all eat standing.

But the most formidable of all their punishments was that whereby one man out of every ten in an entire army was chosen by lot to be put to death.  For correcting a great body of men no more effectual means could be devised; because, when a multitude have offended and the ringleaders are not known, all cannot be punished, their number being too great; while to punish some only, and leave the rest unpunished, were unjust to those punished and an encouragement to those passed over to offend again.  But where you put to death a tenth chosen by lot, where all equally deserve death, he who is punished will blame his unlucky fortune, while he who escapes will be afraid that another time the lot may be his, and for that reason will be careful how he repeats his offence.  The poisoners and the Bacchanals, therefore, were punished as their crimes deserved.
