Jesuits have lent their names to thirty-some craters on the moon. The largest of these is Clavius, named for the 16th century astronomer Christoph Klau (Latinized to Clavius). Clavius is fairly prominent in the lunar southern hemisphere, and at 135 miles across, is visible to a sharp-eyed Earthling even without a telescope.
I found interesting that if you translate the latitude and longitude location of Clavius from the moon to the Earth, this crater would be positioned off the east coast of Argentina.
The Jesuit scientist Clavius put the finishing touches on the Gregorian calendar reform that knocked a chunk of days out of existence in 1582 and realigned vernal equinox to March 21st. He also urged mathematics as part of the education sequence for Jesuits–something not popular in its time. I wonder how much influence he may have had on Matteo Ricci’s phenomenal reception in China, bolstered because of the missionary’s introduction of advanced mathematics to Eastern scientists.
I may have to research a few more of the Jesuits on the moon.
