I’m kind of glad most of the world follows the Gregorian calendar because the Mayan calendar ended today but, the world did not. Also, today is the winter solstice which may have something to do with Mayan calculations.
Pope Gregory VIII established the Gregorian calendar by papal bull on 24 February 1582. He also was the “founder and father” of Pontifical Gregorian University.
I’m pretending these seminarians study there and are between classes. There are nine pontifical universities in Rome and they really could be at any one of them but, I want to continue with the Gregorian theme.
St. Ignatius of Loyola founded the Roman College in 1551 but, I’m picking up the story when it turned into the Pontifical Gregorian University.
With the university counting more than a thousand pupils at this point, Pope Gregory XIII wished to give it a more suitable headquarters. Two blocks near the Via del Corso were expropriated. The new building was inaugurated in 1584, in what became known as the Piazza Collegio Romano. For his sponsorship of the Roman College, Gregory XIII became known as its “founder and father”.
The university in its new space was able to augment the number of disciplines that were taught. New chairs of Church history and liturgy were added. At this time, the university also attained great prestige in the fields of mathematics, physics, and astronomy.
The Gregorian calendar was developed by [German Jesuit mathematician and astronomer] Christopher Clavius, a professor of the university at the time.
NOTE: This is another photograph sitting in media files for over a year. It kind of relates to today being the 21st day of Advent.
