 Lord Cardinal of St. Cecilia, Bishop of Albano, on the 5th day of March, 1616.

In this decree, as is strikingly pointed out by Emil Wohlwill, a distinction is drawn between two classes of writings: those which advocate the positive truth of the Copernican system—which are absolutely interdicted and condemned; and those to which, by some modifications, a hypothetical character can be given—these are to be suspended until the needful corrections have been made. This indicated the precise attitude which the Church thought to take with regard to the Copernican system. As a mere working hypothesis it was not dangerous to the Roman Catholic religion; but as irrefragable truth it shook its very foundations. They were, therefore, determined at Rome that it should not make way as truth—it was to be tabooed, banished, and if possible stifled; but as a mathematical hypothesis, the use of which was obvious even to the Romish savans, it might be allowed to stand. The cardinal's admonition and the decree are in logical agreement with this intention. Galileo was to "renounce" the opinions of Copernicus, that is he was not to maintain them as established fact; as a hypothesis, like the rest of the world he might retain them. But according to the document of 26th February, entire silence was enjoined upon Galileo upon the subject of the double motion of the earth, for in the injunction neither to hold, teach, or defend it in any way (quovis modo), the hypothetical treatment was obviously included.

Perhaps it may be said that they wanted to get rid of the most distinguished and therefore most dangerous defender of the Copernican system, who by his telescopic discoveries had made the controversy a burning question of the day. But this conjecture does not stand the test of close investigation, for Galileo's work on the solar spots, which was based upon the sun’s being stationary, was not placed upon the index of forbidden or suspicious books.
