"Pope Joan"

Jean de Mailly was a Dominican chronicler working in Metz in northeast France in the middle of the 13th century. He wrote a history of the Diocese of Metz, in which he mentions a female pope reigning for two years about the year 1100. She was a talented woman who dressed as a man and became a notary to the pontifical Curia, then a cardinal, and finally a pope.

One day, while riding her horse, she gave birth to a son, revealing the deception. (Honestly, if she were pope for two years and at the end of that time had a son, then at least one person in her orbit knew that she was actually a woman.) With the deception revealed, she got tied to the tail of the horse, dragged around the city, then stoned to death and buried on the spot with the inscription placed over her Petre pater patrum papissae prodito partum ("Peter, Father of Fathers, betray the childbearing of the woman Pope").

This idea tickled the imagination of others, and so it became repeated and expanded. Along came Martin of Troppau, a Polish Dominican, who also wrote history. His history of the world first appeared during the pontificate of Clement IV (1265-68), but it wasn't until the third edition in 1277 that he added the story of the female pope.

Martin places the event in the 9th century, just after the death of Pope Leo IV (847-55). She was an "Englishman" named John of Mainz. Originally taken to Athens as a young girl in male clothing, she became educated until no one was her intellectual equal. She went to Rome (still disguised as a man), and earned so much respect that she was eventually made pope. During a procession from St. Peter's to the Lateran, she gave birth to a child. She died (and was buried) on the spot. Martin refers to her as Johanna. Martin himself was a papal chaplain at the Vatican, so his accounts were widely read, and the legend spread. In a later version of his history he changed the story, saying that she was deposed, imprisoned, and then lived for many years doing penance. The child grew up to become bishop of Ostia, who had her body interred at Ostia.

Later writers give her the birth name of Agnes; others said she was Gilberta. One version of the story says she was given a vision and offered eternal punishment or temporal disgrace. She chose the latter, and that is why she died on the spot after giving birth.

By the 15th century, scholars were looking at these stories and noting their improbability. Unfortunately, the 20th century enjoys escapism and conspiracy theories, and the legend of "Pope Joan" has been embellished to the point where entire books have been written to recount her "history." There is no gap in the history of popes where Joan was excised (although I wrote here, coincidentally, that one annal thought there was a gap before Leo IV, not after.) A 10th-century pope, John XII (955-64), supposedly had a concubine named Joan who was given much authority at the papal palace during his pontificate, and some have speculated that this gave rise to the idea of a "Pope Joan."

But let's say she did become pope; what was she called? She would not have taken the name "Pope Joan"! A Dominican named Bartolomeo Platina (1421-81) called her Pope John VIII. This is silly, since he should have known that there was a Pope John VIII in the 9th century, and not an inconsequential one, either. Let's talk about him next time.

Roger Bacon's "Opus Majus"

Roger Bacon was born about 1219 into a wealthy family in England. He attended classes at Oxford University, where he learned a love of science from masters such as Robert Grosseteste and Adam Marsh. About 1240 he joined the Franciscans, which might have stifled his interests. There was a prohibition on the order against publishing without special permission from the superiors. This was in place because of a work published previously that was considered heretical.

Bacon looked for support and patronage from the papal legate to England, telling him that educational reform was needed. This was one Gui Foucois, although in England he was known as Cardinal Guy de Foulques. The cardinal was not interested in providing financial aid, but was interested in his work and ideas. Unfortunately, without money, Bacon could not afford the writing materials and scientific equipment to produce what he wanted to send.

Then, in 1265, the situation changed. Guy de Foulques was elected Pope Clement IV. Another request to the new pope returned the same result: Clement wanted the information, but would not send money. Bacon could only assemble a shorter work than he wanted to. The result was the Opus Majus or Opus Maius (Latin: "Greater Work"). Its seven sections (which included some of his earlier writings along with new materials) are:

•The Four General Causes of Human Ignorance (believing in an unreliable source,  sticking to custom, ignorance shared by others, pretending to knowledge)
•The Affinity of Philosophy with Theology (concludes that Holy Scripture is the foundation of all sciences)
•On the Usefulness of Grammar (a study of Latin, Greek, Hebrew, Arabic)
•The Usefulness of Mathematics in Physics (in this section he proposes changes to fix the Julian calendar)
•On the Science of Perspective (the anatomy of the eye and brain; light, vision, reflection and refraction, etc.)
•On Experimental Knowledge (a review of alchemy, gunpowder, and hypothesizes microscopes, telescopes, eyeglasses, machines that fly, and ships driven be steam)
•A Philosophy of Morality (philosophy and ethics)

It was sent to Clement in late 1267 or early 1268; however, Clement died in 1268. We do not know if he even had opportunity to read what he had requested.

"The Science of Perspective" was about optics. In that section, he discussed the anatomy of the eye, and how light is affected by distance, reflection and refraction. He also goes into mirrors and lenses. Most of this knowledge of optics came from Alhazen's Book of Optics, previously discussed here, and Robert Grosseteste's work on optics based on Al-Kindi, of whom I have never written before; I think there's my next topic.

Nachmanides

First, let's talk about the name. He was born Moses ben Nachman. He sometimes called himself Ramban, an acronym for Rabbi Moses ben Nachman. Nachmanides is the Greek form of his name, and how he is recognized in western literature. He lived from 1194 - 1270, and lived most of his life  in Catalonia.

He was a scholar, a physician, a philosopher and poet. He began writing commentary on Jewish law at the age of 16. He believed that the rabbis of the Talmud and Mishnah were not to be criticized. He criticized his scholarly predecessor, Maimonides, however. Where Maimonides described any story in the Old Testament where angels appear as a prophetic vision rather than a true angelic visitation on Earth, and tried to explain some of the events in the Bible as naturally occurring, Nachmanides asserted that

no man can share in the Torah of our teacher Moses unless he believes that all our affairs, whether they concern masses or individuals, are miraculously controlled, and that nothing can be attributed to nature or the order of the world.

Previous posts discuss his participation in the Disputation of Barcelona and its outcome. He wrote an account of the debate afterward. Pablo Christiani, his chief opponent in the debate, seized on this account as further proof of blasphemy: he found objectionable passages and went to the head of the Dominicans, Raymond de Penyafort. A charge was brought against Nachmanides, and the complaint was brought before King James. Nachmanides pointed out that his account contained nothing that he had not already said in the presence of the king during the disputation, where the king himself had allowed him to speak freely. His innocence was clear, but the Dominicans wanted results, so Nachmanides was exiled for two years.

An appeal to Pope Clement IV made the exile permanent. Nachmanides, at the age of 70, had to leave his lifelong home. He eventually made his way to Jerusalem, where he reestablished the Jewish community that had been disrupted by the efforts of the First Crusade. He also established a synagogue that is to this day known as the Ramban Synagogue. He died at the age of 76; his burial place is unknown.

This blog has previously discussed Popes Clement I, II, III, V, VI, but never IV, the man who made Ramban's exile permanent. I think I have my topic for tomorrow.
