the greatest terror and greatest clemency

 So, again, in his book of Apophthegms, which he collected, we see that he esteemed it more honour to make himself but a pair of tables, to take the wise and pithy words of others, than to have every word of his own to be made an apophthegm or an oracle, as vain princes, by custom of flattery, pretend to do. And yet if I should enumerate divers of his speeches, as I did those of Alexander, they are truly such as Solomon noteth, when he saith, Verba sapientum tanquam aculei, et tanquam clavi in altum defixi: whereof I will only recite three, not so delectable for elegancy, but admirable for vigour and efficacy.
As first, it is reason he be thought a master of words, that could with one word appease a mutiny in his army, which was thus: The Romans, when their generals did speak to their army, did use the word Milites, but when the magistrates spake to the people they did use the word Quirites. The soldiers were in tumult, and seditiously prayed to be cashiered; not that they so meant, but by expostulation thereof to draw Caesar to other conditions; wherein he being resolute not to give way, after some silence, he began his speech, Ego Quirites, which did admit them already cashiered — wherewith they were so surprised, crossed, and confused, as they would not suffer him to go on in his speech, but relinquished their demands, and made it their suit to be again called by the name of Milites.
The second speech was thus: Caesar did extremely affect the name of king; and some were set on as he passed by in popular acclamation to salute him king. Whereupon, finding the cry weak and poor, he put it off thus, in a kind of jest, as if they had mistaken his surname: Non Rex sum, sed Caesar; a speech that, if it be searched, the life and fulness of it can scarce be expressed. For, first, it was a refusal of the name, but yet not serious; again, it did signify an infinite confidence and magnanimity, as if he presumed Caesar was the greater title, as by his worthiness it is come to pass till this day. But chiefly it was a speech of great allurement toward his own purpose, as if the state did strive with him but for a name, whereof mean families were vested; for Rex was a surname with the Romans, as well as King is with us.
The last speech which I will mention was used to Metellus, when Caesar, after war declared, did possess himself of this city of Rome; at which time, entering into the inner treasury to take the money there accumulate, Metellus, being tribune, forbade him. Whereto Caesar said, “That if he did not desist, he would lay him dead in the place.” And presently taking himself up, he added, “Young man, it is harder for me to speak it than to do it — Adolescens, durius est mihi hoc dicere quam facere.” A speech compounded of the greatest terror and greatest clemency that could proceed out of the mouth of man. But to return and conclude with him, it is evident himself knew well his own perfection in learning, and took it upon him, as appeared when upon occasion that some spake what a strange resolution it was in Lucius Sylla to resign his dictators, he, scoffing at him to his own advantage, answered, That Sylla could not skill of letters, and therefore knew not how to dictate.
