But I shall discuss these and other topics with you at greater length with pleasure and much intensity, and I shall hand you more of my writings if you visit me some day as you promise. (…) Yet I would not want hard luck to force you to come to me, but rather your own judgment as well as your love and affection for the studies which we share. Nevertheless, whatever comes to pass, you will find in me not a follower of fortune, whatever that may be, but your friend who even under untoward circumstances will not fail you with his advice and help, but rather will advance you to everything that is best. And if you arrive soon, perhaps we shall find arrangements which will hereafter be more advantageous for you and your family than previously.
Farewell. (…)
Your most affectionate
Tycho Brahe
