On the Antiquities of Prussia

...pride. For you will be able to boast with the best right that the region which the fathers had received as barbaric, uncultivated, rough, idolatrous, foul, and destitute of all things—that same region they restored and left behind as splendid, cultivated, civilized, wealthy, humane, and, what is greatest, Christian. O too-happy Prussia, if it knew its own goods under that principate! Finally, you will easily perceive, most illustrious prince, by what just judgment of God Prussia returned to the habitation of the Germans, since it is both a part of Germany and, from the beginning of time, owed to and inhabited by the Germans, as is testified by the evidence of the most brilliant writers. Why, in my judgment, should it be inhabited or administered by any other peoples? I have taken on this province of writing, not so much of my own volition as by the order of the venerable prelate Iobus of Pomesania, having been attempted by no one before, so that I might fight on my own behalf against whoever thinks otherwise concerning the borders and people of Prussia, as if for hearth and home, preferring to suffer the ultimate consequences rather than yield ignobly. Therefore, I ask you, invincible prince, born for arms, by your virtue, do not cease to bring aid to so pious and just a war, so that with joined forces we may eliminate the entire dregs of the barbarians from these your borders. For there is no doubt in my mind that if it must be done with your strength, we shall easily reclaim this coast from the hands of those who unjustly occupy it. Which will soon happen, if the fates allow, and your ancestral virtues, and the glorious deeds of your progenitor, prompt it.

Now let us proceed to the plan.
