St Robert Bellarmine is perhaps best known for his dealings with one Galileo Galilei, whom he warned off teaching the Copernican ideas that would later underpin astronomy. However, a closer look at the interaction between the theologian and the scientist suggests that there was more to the Galileo Affair than meets the eye.
A True Demonstration: Bellarmine and the Stars as Evidence Against Earth’s Motion in the Early Seventeenth Century
Article (PDF)- 17 pages
- High school level and above
This 2011 article from Logos: A Journal of Catholic Thought and Culture presents the following argument: In 1615 Robert Cardinal Bellarmine demanded a “true demonstration” of Earth’s motion before he would cease to doubt the Copernican world system. No such demonstration was available because the geocentric Tychonic world system was a viable alternative to the heliocentric Copernican system. On the contrary, recent work concerning early observations of stars suggests that, thanks to astronomers’ misunderstanding of the images of stars seen through the telescope, the only “true demonstration” the telescope provided in Bellarmine’s day showed the earth not to circle the Sun. This had been discussed by the German astronomer Simon Marius, in his Mundus Iovialis, just prior to Bellarmine’s request for a “true demonstration.”
Bellarmine – The Louvain Lectures
Book- 50 pages

The Louvain Lectures, a short book published by the Vatican Observatory in 1984, was written by Ugo Baldini and Fr. George V. Coyne, S. J. (then Director of the Vatican Observatory). It was part of a series of works called the Studi Galileiani, created in response to Pope St. John Paul II’s expressed desire “that theologians, scholars and historians, animated by a spirit of sincere collaboration, will study the Galileo case more deeply”. The book focuses on astronomy-related lectures given by St. Robert Bellarmine in 1570, when Bellarmine was not yet 30 years of age. It also includes Bellarmine’s handwritten version of his 1616 declaration to Galileo.

An article by Vatican Observatory Director Br. Guy Consolmagno, S. J., published on the British Jesuit web site Thinking Faith about Cardinal Bellarmine, a Jesuit cardinal and saint famous for opposing Galileo’s theories. “An oft-quoted quip suggests Bellarmine was a better scientist than Galileo, while Galileo’s letter to the Grand Duchess showed him to be a better theologian than Bellarmine.” As serious analysis, the quip falls short of the mark. The real problem with both parties is that our modern idea of what science is and how it proceeds was only just being born at this time.

Decree of Approval for the work “Elements of Astronomy” by Giuseppe Settele, in support of the heliocentric system (1820)
Pope Pius VII
- Article
- 300 words
- General audiences
The 1820 decree under Pope Pius VII removing all remaining prohibitions against the Copernican system. This arose from the request of Fr. Giuseppe Settele for an imprimatur on his book Elementi di ottica e di astronomia (Elements of Optics and Astronomy), which referenced Earth’s motion. The request was denied; Settele appealed to the Pope.

Greipl, eds., Copernico, Galilei e la chiesa : fine della controversia (1820) : gli atti del Sant’Uffizio {i.e. Copernicus, Galileo, and the Church: The End of the Controversy (1820), Acts of the Holy Office} (Florence: Leo Olschki, 1992), pp. 300-301.
[Rome], 1820 VIII 16
Vol. I, fol. 174v (Bruni, scribe)
The Assessor of the Holy Office has referred the request of Giuseppe Settele, Professor of Optics and Astronomy at La Sapienza University, regarding permission to publish his work Elements of Astronomy in which he espouses the common opinion of the astronomers of our time regarding the earth’s daily and yearly motions, to His Holiness through Divine Providence, Pope Pius VII. Previously, His Holiness had referred this request to the Supreme Sacred Congregation and concurrently to the consideration of the Most Eminent and Most Reverend General Cardinal Inquisitor. His Holiness has decreed that no obstacles exist for those who sustain Copernicus’ affirmation regarding the earth’s movement in the manner in which it is affirmed today, even by Catholic authors. He has, moreover, suggested the insertion of several notations into this work, aimed at demonstrating that the above mentioned affirmation [of Copernicus], as it is has come to be understood, does not present any difficulties; difficulties that existed in times past, prior to the subsequent astronomical observations that have now occurred. [Pope Pius VII] has also recommended that the implementation [of these decisions] be given to the Cardinal Secretary of the Supreme Sacred Congregation and Master of the Sacred Apostolic Palace. He is now appointed the task of bringing to an end any concerns and criticisms regarding the printing of this book, and, at the same time, ensuring that in the future, regarding the publication of such works, permission is sought from the Cardinal Vicar whose signature will not be given without the authorization of the Superior of his Order.

This paper, by Fr. George V. Coyne, S. J., Director of the Vatican Observatory from 1978 to 2006, aims to delineate two of the many tensions which bring to light the contrasting views of Galileo Galilei and of Cardinal Robert Bellarmine with respect to the Copernican-Ptolemaic controversies of the 16th and 17th centuries: their respective positions on Aristotle’s natural philosophy and on the interpretation of Sacred Scripture. Galileo’s telescopic observations, reported in his 1610 book Sidereus Nuncius, were bringing about the collapse of Aristotle’s natural philosophy. Galileo taught that there was no science in Scripture.

Fr. George V. Coyne, S. J., Director of the Vatican Observatory from 1978 to 2006, writes that Galileo, during the very last year of what he himself described “as the best [eighteen] years of his life” spent at the University of Padua, first observed the heavens with a telescope. Fr. Coyne writes that in order to appreciate the marvel and the true significance of those observations we must appreciate the historical precedents which will have important repercussions on the intellectual climate in Europe at the time of Galileo and, therefore, on the critical intellectual period through which Galileo himself was passing at the time those observations were made.
The Work of the Best and Greatest Artist: A Forgotten Story of Religion, Science, and Stars in the Copernican Revolution
Article (PDF)- 29 pages
- High school level and above
This 2012 article from Logos: A Journal of Catholic Thought and Culture presents the following argument: In 1576 the English astronomer Thomas Digges (1546–95) published his English translation of Nicholaus Copernicus’s (1473–1543) De Revolutionibus Orbium Coelestium together with a sketch of the Copernican universe under the heading “A Perfit description of the Cœlestial Orbes”. Because Digges’s sketch shows the planets circling the Sun, surrounded by an infinite expanse of stars, it is often hailed as a forerunner of the modern, scientific understanding of an infinite universe in which the Earth is but a speck. However, Digges was illustrating not the insignificance of Earth but the greatness of a universe of stars that testified to the omnipotence and magnificence of God. Ideas such as Digges’s played a prominent role in Copernican thought, so much so that Copernicans cited Divine Omnipotence to answer one of the most powerful scientific objections to the heliocentric theory. This Copernican use of religion to answer a scientific objection to heliocentrism greatly troubled one of the most prominent defenders of geocentrism, the Italian Jesuit astronomer Giovanni Battista Riccioli (1598–1671). The story of Digges, Riccioli, and the stars challenges the modern portrayal of the Copernican Revolution as being a contest of religion versus science: geocentricism versus heliocentrism. It also raises questions about how historians and scientists, and in particular Catholic historians and scientists, could forget such a dynamic part of the history of ideas.

Coyne, Galileo's observations
Opposition to Galileo was scientific, not just religious
Article- 1000 words
- General audiences
This article by Christopher Graney was originally published by Aeon, and later republished by The Atlantic and others. It discusses astronomical work published in 1614 by Johann Georg Locher, a student of the Jesuit astronomer Christoph Scheiner. There is a great contrast between how Galileo portrayed Locher’s work, and the work itself. Graney writes, “Locher matters. Science’s history matters. Anti-Copernicans such as Locher and Brahe show that science has always functioned as a contest of ideas, and that science was present in both sides of the vigorous debate over Earth’s motion.”

The Jesuits and Galileo: Fidelity to Tradition and the Adventure of Discovery

An article by Fr. George Coyne, S. J., in the journal Forum Italicum. Fr. Coyne, who was Director of the Vatican Observator from 1978 to 2006, writes:
This paper investigates the tensions within the Society of Jesus, especially at the Roman College, at the time of Galileo and how they were resolved (or not) in a spirit of accommodation which was maturing at that time and which has entered into the Jesuit blood- stream. Jesuits at the Roman College confirmed Galileo’s earth-shaking observations, reported in his Sidereus Nuntius. Aristotle’s physics was crumbling. Would Aristotelian philosophy, which was at the service of theology, also collapse? Controversies over the nature of sunspots and of comets held implications for the very foundations of Christian belief. Some Jesuits saw the threat and faced it with an astute view into the future; others, though pioneers as scientists, could not face the larger implications of the scientific revolution to which they contributed with Galileo. Much of what occurred can be attributed to the strong personalities of the individual Jesuit antagonists, and Cardinal Robert Bellarmine will prove to be one of the most important of those personages.

Fr. George V. Coyne, S. J., Director of the Vatican Observatory from 1978 to 2006, writes: “On October 31, 1992, John Paul II in an address to the Pontifical Academy of Sciences said that one of the lessons of the Galileo affair is that we now have a more correct understanding of the authority that is proper to the Church and that: ‘From the Galileo case one can draw a lesson which applies to us today, in view of analogous situations which come forth today and which may come forth in the future.’ Just 350 years before, Pope Urban VIII had declared that Galileo had made himself guilty of an ‘opinion very false and very erroneous and which had given scandal to the whole Christian world.’ The contrast between these two official Church judgments on Galileo separated by a 350-year period is enormous. The question is: What does it bode for the next 350 years? So the import of this paper is not just academic; it attempts to present a judgment on the past and on the present with a view to the future.”

Mathematical Disquisitions – The Booklet of Theses Immortalized by Galileo
Book- 176 pages
- High school level and above
This 2017 book by Christopher M. Graney is the first complete English translation of an astronomical text written by scientists who stood opposite Galileo in the debate on the question of Earth’s motion. Galileo painted a very unfavorable portrait of Mathematical Disquisitions and its Jesuit authors, but the book itself turns out to be a competent scientific work and not much like Galileo’s portrayal of it.
From the publisher, the University of Notre Dame Press:
Mathematical Disquisitions: The Booklet of Theses Immortalized by Galileo offers a new English translation of the 1614 Disquisitiones Mathematicae, which Johann Georg Locher wrote under the guidance of the German Jesuit astronomer Christoph Scheiner. The booklet, an anti-Copernican astronomical work, is of interest in large part because Galileo Galilei, who came into conflict with Scheiner over the discovery of sunspots, devoted numerous pages within his famous 1632 Dialogue Concerning the Two Chief World Systems—Ptolemaic and Copernican to ridiculing Disquisitiones. The brief text (the original was approximately one hundred pages) is heavily illustrated with dozens of original figures, making it an accessible example of “geocentric astronomy in the wake of the telescope.”
The treatise provides valuable insight into the astronomical debates of the seventeenth century, a time when the question of the Earth’s motion was still very much in flux. Whereas Galileo’s works are readily available, there are far fewer translations of works arguing the other side. Christopher Graney’s translation focuses on the mathematical and astronomical core of Locher’s work and is suitable for undergraduate students in courses on the history of science, philosophy of science, astronomy, and physics.
