All these dangers, therefore, which attend the contrivance of a plot, must be passed through before you come to its execution; or if you would escape them, you must observe the following precautions: Your first and surest, nay, to say truth, your only safeguard, is to leave your accomplices no time to accuse you; for which reason you must impart the affair to them, only at the moment when you mean it to be carried out, and not before. Those who have followed this course have wholly escaped the preliminary dangers of conspiracies, and, generally speaking, the others also; indeed, I may say that they have all succeeded, and that it is open to every prudent man to act as they did. It will be enough to give two instances of plots effected in this way. Nelematus, unable to endure the tyranny of Aristotimus, despot of Epirus, assembling many of his friends and kinsmen in his house, exhorted them to free their country; and when some of them asked for time to consider and mature their plans, he bade his slaves close the doors, and told those assembled that unless they swore to go at once and do as he directed he would make them over to Aristotimus as prisoners. Alarmed by his threats, they bound themselves by a solemn oath, and going forth at once and without delay, successfully carried out his bidding. A certain Magus having fraudulently usurped the throne of Persia; Ortanes, a grandee of that realm, discovering the fraud, disclosed it to six others of the chief nobility, telling them that it behoved them to free the kingdom from the tyranny of this impostor. And when some among them asked for time, Darius, who was one of the six summoned by Ortanes, stood up and said, “Either we go at once to do this deed, or I go to the Magus to accuse you all.” Whereupon, all rising together, without time given to any to change his mind, they went forth and succeeded in effecting their end. Not unlike these instances was the plan taken by the Etolians to rid themselves of Nabis, the Spartan tyrant, to whom, under pretence of succouring him, they sent Alasamenes, their fellow-citizen, with two hundred foot soldiers and thirty horsemen. For they imparted their real design to Alasamenes only, charging the rest, under pain of exile, to obey him in whatever he commanded. Alasamenes repaired to Sparta, and never divulged his commission till the time came for executing it; and so succeeded in putting Nabis to death.
