However, his basic notion of emulating Roman practices was slowly and pragmatically adapted by many later rulers and commanders, most notably Maurice of Nassau  and Gustavus Adolphus of Sweden.
And as the opportunity has not come to me to be able to show the preparations I would make to bring the military to your ancient organization, and it I have not done so, I cannot be blamed either by you or by others.
At the end of the sixteenth century, for instance, Justus Lipsiusin his influential writings on military affairs, also treated the Roman military order as a permanently valid model.
Whence there resulted that many men were killed because of their insolence, for they gave the Empire and took it away from anyone they wished, and it often occurred that at one time there were many Emperors created by the several armies. FABRIZIO: I will tell you: if I should have to organize an army where there is none, it would be necessary to select all those men who were more capable, as long as they were of military age, in order to instruct them as I would tell them: but if I should have to make the Deletto in places where the army was already organized, in order to supplement it, I would take those of seventeen years of age, because the others having been taken for some time would have been selected and instructed.
Whence it is clearer than the sun, that if that man had practiced war as his profession, and by means of it thought to obtain some advantage for himself, having so many provinces which he could plunder, he would not have asked permission to return to take care of his fields, as each day he could have obtained more than the value of all his possessions.
None the less, whoever considers everything well, will easily find the answer, for this thing of keeping on the men at arms is a corrupt thing and not good. And as they now begun freely to permit men assigned to the army to practice military matters as their profession, there soon resulted that these men became insolent, and they became formidable to the Senate and damaging to the Emperor.
Fabrizio advocates the lifting of soldiers among the common people who will have been educated and trained regularly to be ready when the time came to serve under arms to protect their homeland. Men who want to do something, ought first to prepare themselves with all industry, in order when the opportunity is seen to be prepared to achieve that which they have proposed.
COSIMO: You have made me turn this profession art of soldiering back almost to nothing, and I had supposed it to be the most excellent and most honorable of any: so that if you do not clarify this better, I will not be satisfied; for if it is as you say, I do not know whence arises the glory of Caesar, Pompey, Scipio, Marcellus, and of so many Roman Captains who are celebrated for their fame as the Gods.
COSIMO: If we first desired to hear your discussion of these matters, truly what you have said up to now redoubles that desire. I want to begin from your words, where you said to me that in war which is my profession I have not employed any of the ancient methods.
And I will be grateful if you ask me, for I am about to learn as much from what you ask me, as you will from me replying to you, because many times a wise questioner causes one to consider many things and understand many others which, without having been asked, would never have been understood.
