On this day in history, science was silenced.
In the eyes of the Roman Inquisition, heliocentricity was a foreign and dangerous concept that undermined God’s divine design. And, even more dangerous than the theory, was the man who hailed it as truth— Galileo Galilei.
Galileo published his “Starry Messenger” treatise in 1610, arguing that the Earth orbits the Sun, rebuking the misconception that the opposite was true. By February 1616, the Inquisition gathered a group of theologians, referred to as Qualifiers, to determine whether Galileo was actively committing heresy.
They came to a unanimous agreement: the suggestion that the Sun is stationary within the cosmos directly went against scripture. Galileo was instructed by Pope Paul IV to reject Copernican opinions and was forbidden to defend heliocentrism, both verbally or in writing. Galileo, fearing harsh consequences, surrendered to these terms.
The Pope also assured Galileo that, as long as the Pope was alive, Galileo would not face prosecution. The biggest question that arose from this trial was the technicality of whether the Qualifiers ordered Galileo to either recant his beliefs entirely or if he was simply forbidden from teaching them.
Nevertheless, this would prove to be only Galileo’s first trial, with his second leading to his eventual house arrest and publication of his most renowned works. The Galileo Affair lives on as a microcosm of the enduring battle between science and religion, and solidifying Galileo as a martyr of intellectual freedom.
