Conspirators against their country, whether trusting to their own forces or to foreign aid, have had more or less success in proportion as they have been favoured by Fortune. Catiline, of whom we spoke just now, was overthrown. Hanno, who has also been mentioned, failing to accomplish his object by poison, armed his partisans to the number of many thousands; but both he and they came to an ill end. On the other hand, certain citizens of Thebes conspiring to become its tyrants, summoned a Spartan army to their assistance, and usurped the absolute control of the city. In short, if we examine all the conspiracies which men have engaged in against their country, we shall find that few or none have been quelled in their inception, but that all have either succeeded, or have broken down in their execution. Once executed, they entail no further risks beyond those implied in the nature of a princedom. For the man who becomes a tyrant incurs all the natural and ordinary dangers in which a tyranny involves him, and has no remedies against them save those of which I have already spoken. This is all that occurs to me to say on the subject of conspiracies. If I have noticed those which have been carried out with the sword rather than those wherein poison has been the instrument, it is because, generally speaking, the method of proceeding is the same in both. It is true, nevertheless, that conspiracies which are to be carried out by poison are, by reason of their uncertainty, attended by greater danger. For since fewer opportunities offer for their execution, you must have an understanding with persons who can command opportunities. But it is dangerous to have to depend on others. Again, many causes may hinder a poisoned draught from proving mortal; as when the murderers of Commodus, on his vomiting the poison given him, had to strangle him.
