But upon what are based these categories, lovely amp; unlovely, strong amp; weak, et cetera? Why, upon the division of circles made by the knowable, that is constructable, regular polygons, as for instance is set out in my Mysterium cosmographicum; that is, the harmonic primordial relationships foreshadowed in the divine being. Thus all animated things, human amp; otherwise, as well as all the vegetable world, are influenced from heaven by the appropriate geometric instinct pertaining to them. All their activities are affected, individually shaped amp; guided by the light rays present here below and sensed by all these objects, as well as by the geometry amp; harmony which occurs between them by virtue of their motion, in the same way as the flock is affected by the voice of the shepherd, the horses on a wagon by the driver's shout, and the dance of the peasant by the skirl of the bagpipes. This is what I believe, and none of your monkey-shine will convince me otherwise.
I trust this frank German talk has not offended you, my dear Röslin. You live in my affections always, though sometimes I may snap amp; snarl, as if the habit of your friend and colleague, Johannes Kepler

Frau Katharina amp; Heinrich Kepler: at Weilderstadt
(To be read in their presence by G. Raspe, notary. Fee enclosed.)
Loved ones: I write to say that we have arrived home safely amp; well. Friedrich has a cough, but otherwise remains strong. Preparations for our dear Regina 's wedding are already well advanced: she is wonderfully capable in matters such as these. Her intended husband is a fine amp; honourable man, and well set up. He came this week to pay us his respects. Of course, he has been here before, but not as a betrothed. I find him somewhat formal, and wonder if he may not prove inflexible. Everything was most polite. I have no doubt that Regina will be well treated by him, and will be happy, perhaps. They move to Pfaf-fenhofen in the Upper Palatinate after the wedding. There is talk of plague there.
We are still in our rooms in the old Cramer Buildings, and I think must remain here for the present. The quarters are satisfactory, for we are on the bridge, and so have the benefit of the river. The building is of stone, therefore there is less danger of fires breaking out, a thing I have always feared, as you know. Also we are situated in a good part of the city. At Wenzel College in the Old Town, where we lived before, things were very different: the streets there are bad, ill-paved and always strewn with every kind of filth, the houses are bad, roofed with straw or wattles, and there is a stink that would drive back the Turk. Our landlord here, though, is an unmannerly ruffian, and I have many differences with him, which upsets my digestion. Barbara tells me not to mind him. Why is it, I wonder, that people behave so badly toward each other? What is to be gained by fretting amp; fighting? I think there are some in the world who must sustain themselves by making their fellow men suffer. This is as true for the landlord who hounds his tenants, as it is for the infidel torturing his slaves to death: only the degree of evil differs, not the quality. These are the things I think about, when my duties at court and my scientific studies allow me time to think at all. Not that I do much scientific work now, for my health is not good, with frequent fevers and an inflammation of the bowel, and my mind for the most part prostrate in a pitiful frost. But I do not complain. God is good.
We move in the midst of a distinguished society here in Prague. The Imperial Counsellor and First Secretary, Johann Polz, is very fond of me. His wife amp; his whole family are conspicuous for their Austrian elegance and their distinguished amp; noble manners. It would be due to their influence, if on some future day I were to make progress in this respect, though, of course, I am still far away from it (there is a difference between being a renowned mathematician and being great in society!). Yet notwithstanding the shabbiness of my household and my low rank, I am free to come amp; go in the Polz house as I please – and they are considered to belong to the nobility! I have other connections. The wives of two imperial guards acted as godmothers at Susanna's baptism. Stefan Schmid, the Imperial Treasurer; Matthäus Wackher, the Court Barrister; and His Excellency Joseph Hettler, the Baden Ambassador, all stood for our Friedrich. And at the ceremonies for little Ludwig, the Counts Palatine Philip Ludwig amp; his son Wolfgang Wilhelm von Pfalz-Neuburg were present. So you see, we are beginning to rise in the great world! All the same, I do not forget my own people. I think of you often, and worry for your well-being. You must take care of each other, and be kind. Mother, think on my warnings when last we spoke. Heinrich, cherish your mother. And in your prayers remember
your son amp; brother, Johann
(Herr Raspe, for your eyes only: watch Frau Kepler's doings, as I requested, and keep me informed. I shall pay you for these services.)

Signor Prof. Giorgio Antonio Magini: at Bologna
It is as if one had woken up to find two suns in the sky. That is only, of course, a way of putting it. Two suns would be a miracle, or magic, whereas this has been wrought by human eye and mind. It seems to me that there are times when, suddenly, after centuries of stagnation, things begin to flow all together as it were with astonishing swiftness, when from all sides streams spring up and join their courses, and this great confluence rushes on like a mighty river, carrying upon its flood all the broken amp; pathetic wreckage of our misconceptions. Thus, it is not a twelvemonth since I published my Astronomia nova, changing beyond recognition our notion of celestial workings: and now comes this news from Padua! Doubtless you in Italy are already familiar with it, and I know that even the most amazing things can come to seem commonplace in only a little time; for us, however, it is still new amp; wonderful amp; somewhat frightening.
Word was brought to me first by my friend Matthäus Wackher, Court Barrister amp; Privy Counsellor to His Majesty, who had it from the Tuscan Ambassador lately arrived here. Whackher came to see me at once. The day was bright and blustery, with a promise of spring, I will remember it always, as one remembers only a handful of days out of a lifetime. I saw, from the window of my study, the Counsellor's carriage come clattering over the bridge, and old Wackher with his head stuck out at the window, urging the driver on. Does excitement such as his that day send out before it palpable emanations? For even as I watched him coming, I felt nervous stirrings within me, though I knew nothing of what he had to tell me. I ran down and met the carriage arriving at my door. Herr Wackher was already babbling at me before I could grasp it. Galileus of Padua had turned upon the night sky a two-lensed perspicillum-a common Dutch spyglass, in fact-and by means of its 30-times magnification, had discovered four new planets.
I experienced a wonderful emotion while I listened to this curious tale. I felt moved in my deepest being. Wackher was full of joy amp; feverish excitement. At one moment we both laughed in our confusion, the next he continued his narrative and I listened intently-there was no end to it. We clasped hands and danced together, and Wackher's little dog, which he had brought with him, ran about in circles barking shrilly, until, overcome by our hilarity and quite beside itself, it jumped up and clasped me amorously about the leg, as dogs will, licking its lips and insanely grinning, which made us laugh the harder. Then we went inside and sat down, calmer now, over a jug of ale.
