Galileo’s Inquisition Trial Revisited

This book shows that the known accounts of Galileo’s trial leave many important facts unexplained or even clash with them. A most careful reading of the relevant documents and treatises backs an interpretation which has Pope Urban VIII sue Galileo for denying God’s omnipotence or His omniscience by admitting the «absolute truth» of Copernicanism. The Pope’s opinion results from an argument he fully trusts, together with his belief that Galileo failed to fulfill a condition to which the publication of the Dialogue was subjected. That the trial does not end with a conviction for Urban’s awful «formal heresy» but merely for «vehement suspicion of heresy», with the «heresy» consisting in the pseudo-heretical belief in a doctrine contrary to the Bible, all this is due to the existence of a Galileo-friendly party inside the Holy Office, led by Cardinal Francesco Barberini and powerful enough to wring a compromise from the Pope.
