On the morning of June 22, 1633, Galileo, dressed in the white shirt of penitence, entered the large hall of the Inquisition building. He knelt and listened to his sentence: "Whereas you, Galileo, the son of the late Vincenzo Galilei, Florentine, aged seventy years, were in the year 1615 denounced to this Holy Office for holding as true the false doctrine....." The reading continued for seventeen paragraphs:

And, so that you will be more cautious in future, and an example for others to abstain from delinquencies of this sort, we order that the book Dialogue of Galileo Galilei be prohibited by public edict. We condemn you to formal imprisonment in this Holy Office at our pleasure.

As a salutary penance we impose on you to recite the seven penitential psalms once a week for the next three years. And we reserve to ourselves the power of moderating, commuting, or taking off, the whole or part of the said penalties and penances.

This we say, pronounce, sentence, declare, order and reserve by this or any other better manner or form that we reasonably can or shall think of. So we the undersigned Cardinals pronounce.

Seven of the ten cardinals signed the sentence.

Following the reading of the sentence, Galileo knelt to recite his abjuration:

....[D]esiring to remove from the minds of your Eminences, and of all faithful Christians, this strong suspicion, reasonably conceived against me, with sincere heart and unfeigned faith I abjure, curse, and detest the aforesaid errors and heresies, and generally every other error and sect whatsoever contrary to the said Holy Church; and I swear that in the future I will never again say or assert, verbally or in writing, anything that might furnish occasion for a similar suspicion regarding me....

I, the said Galileo Galilei, have abjured, sworn, promised, and bound myself as above; and in witness of the truth thereof I have with my own hand subscribed the present document of my abjuration, and recited it word for word at Rome, in the Convent of Minerva, this twenty-second day of June, 1633.

I, Galileo Galilei, have abjured as above with my own hand.

Two days later, Galileo was released to the custody of the Florentine ambassador. Niccolini described his charge as "extremely downcast over his punishment." After six days in the custody of Niccolini, custody of Galileo transferred to Archbishop Piccolomini in Sienna. In late 1633, Galileo received permission to move into his own small farmhouse in Arcetri, where he would grow blind and, in 1641, die.
