"Being very young and having scarcely finished my course of Philosophy which I left off, as being set upon other employments, there chanced to come into these parts a certain foreigner of Rostock, whose name as I remember, was Christianus Vurstitius, a follower of Copernicus, who in an Academy made two or three lectures upon this point, to whom many flock't as auditors; but I thinking they went more for the novelty of the subject than otherwise, did not go to hear him; for I had concluded with myself that that opinion could be no other than a solemn madnesse. And questioning some of those who had been there, I perceived they all made a jest thereof, except one, who told me that the business was not altogether to be laugh't at, and because this man was reputed by me to be very intelligent and wary, I repented that I was not there, and began from that time forward as oft as I met with anyone of the Copernican persuasion, to demand of them, if they had always been of the same judgment; and of as many as I examined, I found not so much as one, who told me not that he had been a long time of the contrary opinion, but to have changed it for this, as convinced by the reasons proving the same: and afterwards questioning them, one by one, to see whether they were well possest of the reasons of the other side, I found them all to be very ready and perfect in them; so that I could not truly say that they had took up this opinion out of ignorance, vanity, or to show the acuteness of their wits. On the contrary, of as many of the Peripateticks and Ptolemeans as I have asked (and out of curiosity I have talked with many) what pains they had taken in the Book of Copernicus, I found very few that had so much as superficially perused it; but of those whom, I thought, had understood the same, not one; and moreover, I have enquired amongst the followers of the Peripatetick Doctrine, if ever any of them had held the contrary opinion, and likewise found that none had. Whereupon considering that there was no man who followed the opinion of Copernicus that had not been first on the contrary side, and that was not very well acquainted with the reasons of Aristotle and Ptolemy; and on the contrary, that there is not one of the followers of Ptolemy that had ever been of the judgment of Copernicus, and that had left that to embrace this of Aristotle, considering, I say, these things, I began to think, that one, who leaveth an opinion imbued with his milk, and followed by very many, to take up another owned by very few, and denied by all the Schools, and that really seems a very great Parodox, must needs have been moved, not to say forced, by more powerful reasons. For this cause I am become very curious to dive, as
