Voltaire, eager to undermine the claims of conventional religion by contrasting the infighting of the Catholic Church with the sedate purity, unity and rationality of the students of Euclid, boasted that there were no sects among geometers. This, with the arrival of non-Euclidean geometry in the next century, would prove to be overly optimistic, but more important, invoking geometry as some kind of antithesis of revealed religion was a rhetorical mistake. After all, some of the best geometers of the past two centuries (including Christopher Clavius, the author of the preeminent early-modern version of Euclid's Elements; including Fracois d'Auilon; including Giovanni Girolamo Saccheri, author of books which, after a period of long neglect, would help lay the basis for non-Euclidean geometry) were Jesuits.
