Dionysius Exiguus

We learned a lot about St. Pachomius and his development of the Eastern Coptic Christian monasteries from a biography written over a hundred years after his death by an Eastern Roman monk named Dionysius Exiguus, which means "Dionysius the Humble."

Born c.470 in Scythia Minor—a Roman province north of Constantinople, between the Danube and the Black Sea—he was a "true Roman" by inclination (according to Cassiodorus).  He was a mathematician and astronomer, a theologian, and was well-versed in canon law. He was fluent in both Greek and Latin. This skill allowed him to translate hundreds of important Greek works into Latin, including the "Life of St. Pachomius." He also translated a history of the discovery of the head of John the Baptist. Some translations attributed to him seem to be the earlier work of Marius Mercator (mentioned previously in a post about forgeries).

He came to Rome when Pope Gelasius I summoned him to organize the papal archives. (Gelasius died 496CE, so Dionysius must have been in Rome by that year.) He translated into Latin 401 ecclesiastical canons, including the apostolic canons and the decrees of the councils of Nicaea, Constantinople, Chalcedon, and Sardis, all of which were recorded in Greek, having taken place in the Eastern Mediterranean.

Pope John I in 525 asked him to create a chronology, which he did, using the Julian calendar and tabulating the dates of Easter, that "floating Holy Day" that caused much consternation in the early Church. In the process, Dionysius created a—let's call it a "convention"—that has lasted until today: the use of Anno Domini to describe years since the birth of Christ.

Tomorrow we take a deep dive into those two simple words, what came before, and how they were determined.

The Name of the Pope

It is common practice for popes of the Roman Catholic Church to take a new name—called their regnal name—upon elevation to the Throne of Peter. They will usually offer a reason for the new name. Cardinal Albino Luciani took the names of both his immediate predecessors and called himself Pope John Paul I. When he died after a very short (33 days) reign, Cardinal Karol Wojtyla chose to honor him by taking the name Pope John Paul II upon his accession.

Pope "Mercurius"

It hasn't always been thus, however. Whereas now almost all popes take the name of a saint, early popes used their own names—names that were not always common. So you had popes named Anacletus, Evaristus, Telesphorus, Hyginus, Soter, Eleuterus, Zephyrinus and others among the more common names like Felix and Boniface and John; and they only rarely needed numbers next to their names, because the likelihood of there being more than one pope named "Anterus" or "Eutychian" or "Miltiades" was slight.

The practice of taking a new name began not to honor a predecessor, however, but to avoid an embarrassment.

After the death of Pope Boniface II in October 532, there was a two-month vacancy in the position. Part of the reason for this was a (ahem) change in the process. You see, it had become common for some candidates to ensure their election through bribes and gifts. The Roman Senate forbade this practice just before the death of Boniface. Athalaric, the King of the Ostrogoths in Italy, upheld the Senate's decision, and added his own flourish: a disputed papal election that needed to come before his court would be fined 3000 solidi (a solidi was a gold coin of 4.5 grams) and the money given to the poor.

The cardinals fell into agreement on a distinguished priest of Rome, aged about 60. He was willing to take the job, but he had one concern. His Roman parents had given him a theophoric birth name—a name that honors a god in order to impart luck and protection to a child. His name was Mercurius. Father Mercurius did not think it was appropriate for a Christian pope to bear the name of a Roman god. He decided to take the name of a pope from a decade earlier who had had a good working relationship with Athalaric's grandfather.

And so Father Mercurius became Pope John II, the first pope known to have taken a new name upon election.
