Amongst other things (my loving friend and brother) I remember yet the former friendship had together, when we were schoolfellows and students in the University at Wittenberg, whereas you first studied Physic, Astronomy, Astrology, Geometry, and Cosmography; I to the contrary (you know) studied Divinity: notwithstanding now in any of your own studies I am seen (I am persuaded) further then your self: for sithence I began I have never erred, for (might I speak it without affecting my own praise) my Calendars and other practices have not only the commendations of the common sort, but also of the chiefest Lords and Nobles of this our Dutch Nation: because (which is chiefly to be noted) I write and presaged of matters to come, which all accord and fall out so right, as if they had been already seen before. And for that (my beloved Victori) you write to know my voyage which I made into the Heavens, the which (as you certify me you have had some suspicion of, although you partly persuaded yourself, that it is a thing impossible) no matter for that, it is as it is, and let it be as it will, once it was done, in such manner as now according unto your request I give you here to understand.
