In 1630 he brought the completed manuscript to Riccardi, Master of the Sacred Palace, for permission to print it in Rome. After much reading and re-reading of it both by Riccardi and his associate, Father Visconti, permission was at length granted on condition that he insert a preface and a conclusion practically dictated by Riccardi, emphasizing its hypothetical character.[260] The Pope's own argument was to be used: "God is all-powerful; all things are therefore possible to Him; ergo, the tides cannot be adduced as a necessary proof of the double motion of the earth without limiting God's omnipotence--which is absurd."[261] Galileo returned to Florence in June with the permission to print his book in Rome. Meanwhile the plague broke out. He decided to print it in Florence instead, and on writing to Riccardi for that permission, the latter asked for the book to review it again. The times were too troublesome to risk sending it, so a compromise was finally effected: Galileo was to send the preface and conclusion to Rome and Riccardi agreed to instruct the Inquisitor at Florence as to his requirements and to authorize him to license the book.[262] The parts were not returned from Rome till July, 1631, and the book did not appear till February of the following year, when it was published at Florence with all these licenses, both the Roman and the Florentine ones.

It begins with an outline of the Aristotelian system, then points out the resemblances between the earth and the planets. The second "day" demonstrates the daily rotation of the earth on its axis. The next claims that the necessary stellar parallax is too minute to be observed and discusses the earth's annual rotation. The last seeks to prove this rotation by the ebb and flow of the tides. It is a brilliant book and received a great reception. The authorities of the Inquisition at once examined it and denounced Galileo (April 17, 1633) because in it he not merely taught and defended the "condemned doctrine but was gravely suspected of firm adherence to this opinion."[263] Other charges made against him were that he had printed the Roman licenses without the permission of the Congregation, that he had printed the preface in different type so alienating it from the body of the book, and had put the required conclusion into the mouth of a fool (Simplicio), that in many places he had abandoned the hypothetical treatment and asserted the forbidden doctrine, and that he had dealt indecisively with the matter though the Congregation had specifically condemned the Copernican doctrine as contrary to the express words of the Scripture.[264] [Footnote 263: Doc. in Favaro: 88-89.
