Thou hast also Pisa, where the men are of nature changeable and unreliable, who, although they may be sometimes held in subjection, yet they will ever disdain to serve under a Lucchese. Pistoia is also disloyal to thee, she being eaten up with factions and deeply incensed against thy family by reason of the wrongs recently inflicted upon them. Thou hast for neighbours the offended Florentines, injured by us in a thousand ways, but not utterly destroyed, who will hail the news of my death with more delight than they would the acquisition of all Tuscany. In the Emperor and in the princes of Milan thou canst place no reliance, for they are far distant, slow, and their help is very long in coming. Therefore, thou hast no hope in anything but in thine own abilities, and in the memory of my valour, and in the prestige which this latest victory has brought thee; which, as thou knowest how to use it with prudence, will assist thee to come to terms with the Florentines, who, as they are suffering under this great defeat, should be inclined to listen to thee. And whereas I have sought to make them my enemies, because I believed that war with them would conduce to my power and glory, thou hast every inducement to make friends of them, because their alliance will bring thee advantages and security. It is of the greatest important in this world that a man should know himself, and the measure of his own strength and means; and he who knows that he has not a genius for fighting must learn how to govern by the arts of peace. And it will be well for thee to rule thy conduct by my counsel, and to learn in this way to enjoy what my life-work and dangers have gained; and in this thou wilt easily succeed when thou hast learnt to believe that what I have told thee is true. And thou wilt be doubly indebted to me, in that I have left thee this realm and have taught thee how to keep it.”
