they ought to have set a check on the decemvirs in order to keep them good, dispensed with it, making them the sole magistrates of Rome, and setting aside all others; and this from the excessive desire of the senate to get rid of the tribunes, and of the commons to get rid of the consuls; by which objects both were so blinded as to fall into all the disorders which ensued.  For, as King Ferrando was wont to say, men often behave like certain of the smaller birds, which are so intent on the prey to which nature incites them, that they discern not the eagle hovering overhead for their destruction.

In this Discourse then the mistakes made by the Roman people in their efforts to preserve their freedom and the mistakes made by Appius in his endeavour to obtain the tyranny, have, as I proposed at the outset, been plainly shown.

CHAPTER XLI.—­That it is unwise to pass at a bound from leniency to severity, or to a haughty bearing from a humble.

Among the crafty devices used by Appius to aid him in maintaining his authority, this, of suddenly passing from one character to the other extreme, was of no small prejudice to him.  For his fraud in pretending to the commons to be well disposed towards them, was happily contrived; as were also the means he took to bring about the reappointment of the decemvirate.  Most skilful, too, was his audacity in nominating himself contrary to the expectation of the nobles, and in proposing colleagues on whom he could depend to carry out his ends.  But, as I have said already, it was not happily contrived that, after doing all this, he should suddenly turn round, and from being the friend, reveal himself the enemy of the people; haughty instead of humane; cruel instead of kindly; and make this change so rapidly as to leave himself no shadow of excuse, but compel all to recognize the doubleness of his nature.  For he who has once seemed good, should he afterwards choose, for his own ends, to become bad, ought to change by slow degrees, and as opportunity serves; so that before his altered nature strip him of old favour, he may have gained for himself an equal share of new, and thus his influence suffer no diminution.  For otherwise, being at once unmasked and friendless, he is undone: 

CHAPTER XLII.—­How easily Men become corrupted.

In this matter of the decemvirate we may likewise note the ease wherewith men become corrupted, and how completely, although born good and well brought up, they change their nature.  For we see how favourably disposed the youths whom Appius gathered round him became towards his tyranny, in return for the trifling benefits which they drew from it; and how Quintus Fabius, one of the second decemvirate and a most worthy man, blinded by a little ambition, and misled by the evil counsels of Appius, abandoning his fair fame, betook himself to most unworthy courses, and grew like his master.
