Rumors of trouble reached Galileo and, urged on by his friends, in 1615 he wrote a long formal elaboration of the earlier letter, addressing this one to the Dowager Grand Duchess, but he had only added fuel to the fire. At the end of the year he voluntarily went to Rome, regardless of any possible danger to himself, to see if he could not prevent a condemnation of the doctrine.[246] It came as a decided surprise to him to receive an order to appear before Cardinal Bellarmin on February 26, 1616,[2] and there to learn that the Holy Office had already condemned it two days before. He was told that the Holy Office had declared: first, "that the proposition that the sun is the center of the universe and is immobile is foolish and absurd in philosophy and formally heretical since it contradicts the express words of the Scriptures in many places, according to the meaning of the words and the common interpretation and sense of the Fathers and the doctors of theology; and, secondly, that the proposition that the earth is not the center of the universe nor immobile receives the same censure in philosophy and in regard to its theological truth, it at least is erroneous in Faith."[247] [Footnote 246: Doc. in Favaro: 78.] [Footnote 247: Ibid: 61.] Exactly what was said at that meeting between the two men became the crucial point in Galileo's trial sixteen years later, hence a somewhat detailed study is important. At the meeting of the Congregation on February 25th, the Pope ordered Cardinal Bellarmin to summon Galileo and, in the presence of a notary and witnesses lest he should prove recusant, warn him to abandon the condemned opinion and in every way to abstain from teaching, defending or discussing it; if he did not acquiesce, he was to be imprisoned.[248] The Secret Archives of the Vatican contain a minute reporting this interview (dated February 26, 1616), in which the Cardinal is said to have ordered Galileo to relinquish this condemned proposition, "nec eam de cætero, quovis modo, teneat, doceat aut defendat, verbo aut scriptis," and that Galileo promised to obey.[249] Rumors evidently were rife in Rome at the time as to what had happened at this secret interview, for Galileo wrote to the Cardinal in May asking for a statement of what actually had occurred so that he might silence his enemies. The Cardinal replied:
