Pope Leo vs. the East

When Byzantine Patriarch Michael I Cerularius made known to Pope Leo IX what he considered erroneous practices on the part of the Roman Church, Leo retaliated by reminding Michael that Leo "owned" him, Constantinople, and the Byzantine Empire. His argument for this was the Donation of Constantine.

The Donation (an action represented in the illustration) was an alleged decree from Roman Emperor Constantine I in the 4th century, offering to Pope Sylvester control over all the major dioceses and all the lands of the empire, both East and West. This was proven to be a forgery in the 15th century by the scholar Lorenzo Valla. Leo had no reason to think the Donation was a forgery, however; in fact, he had plenty of motivation to believe it was authentic.

Anyway, in 1054 Leo wrote to Michael, assuring him that the Donation was not a hoax and Michael had better accept that the pope in Rome was the only rightful head of the Church. Not trusting Michael to fall in line, Leo sent Cardinal Humbert of Silva Candida to Constantinople to lay out the proper way forward for the Eastern Church.

Humbert was actually "in the thick" of this issue. Humbert was in Apulia in 1053, where he received a letter from the Byzantine Archbishop Leo of Ohrid that listed Patriarch Michael's complaints about Western Roman Church practices. It was partially this letter that caused Leo to invoke the Donation.

Humbert arrived in Constantinople in spring of 1054 and received a warm welcome from Emperor Constantine X. Michael was much colder, however, but the papal delegation and Byzantine clergy met several times, discussing religious issues with no real progress or compromise being made. During Mass on 16 July Humbert placed a papal bull on the high altar of the Hagia Sophia, excommunicating Michael and his supporters. Michael, in turn, gathered his clerics and four days later excommunicated Humbert and his entourage.

The papal bull is considered by many historians to be invalid, because Humbert delivered it even though Leo had died in on 19 April. Still, the events of 1054 brought to a head the doctrinal differences between east and west and guaranteed the East-West Schism, the official break between the Roman Catholic Church and the Eastern Orthodox Church.

This Schism had been building for many years, and we will look at a timeline of the conflicts that made it inevitable next time.

The Last Medieval Pope

Others may dispute it, but I call Nicholas V the Last Medieval Pope because he saw the Fall of Constantinople to the Turks and the end of the Hundred Years War (I explain more here).

Born Tomasso Parentucelli (13 November 1397 - 24 March 1455), his father died when he was young, leaving Tomasso unable to complete his education until many years later. Achieving a degree in theology, he was hired by Bishop Niccolò Albergati, spending the next 20 years as the bishop's personal assistant and librarian, helping the bishop to acquire a large library. He read as well as curated; his wide knowledge of theology made him valuable and respected.

When Albergati died, Tommaso was offered the position of bishop, but Bologna was going through a some political troubles that made his appointment unlikely. Pope Eugene IV sent him on diplomatic missions at which Tommaso was so successful that he earned a cardinal's hat. Upon Eugene's death, Tommaso was elected to succeed him, taking the name Nicholas to honor his original patron.

He carried his love of learning and arts to the papacy. During his time:

—A library of 5000 volumes was created, including manuscripts rescued from Constantinople after it fell to the Turks. More on the evolution of the new Vatican Library can be found here.

—He promoted the new humanist learning, sending emissaries East to invite Greek scholars from Constantinople.

—He started his papacy by restoring the major Roman basilicas, and cleaning and paving main streets.

—He restored the Aqua Virgo, one of the 11 main aqueducts that used to supply the city before they crumbled into ruin after the fall of Rome. It emptied into a basin that later became the famous Trevi Fountain.

—He had Lorenzo Valla translate Greek histories and literature to make them available to the West.

(He is also known as a supporter of slavery of non-Christians, mentioned here, which later caused controversy among two Christian nations.)

As part of his rebuilding plan, he took 2522 cartloads of marble from the Colosseum, which at that time was used basically as a quarry. The Colosseum has been barely mentioned here, and you might be interested to know what the Middle Ages thought of this great Roman wonder...next time.

Poggio vs. Lorenzo

Lorenzo Valla (c.1407 - 1457) was a scholar and Catholic priest. Like Poggio Bracciolini, he was interested in old manuscripts. His father worked as a lawyer for the pope, and his uncle was a papal secretary. Valla wanted to be an apostolic secretary himself, even entering the priesthood thinking that would help, but never was able to achieve that career.

With his knowledge of Latin and Greek, he analyzed classical texts and wrote treatises on them. One of his bars to working for the papacy may have been his work that established the Donation of Constantine as a forgery. I previously wrote about him and the Donation here.

He likewise showed the inauthenticity of a supposed letter from Christ to Abgar (1st century ruler of Edessa). His questioning of other religious documents and his questioning of the usefulness of monastic life roused the ire of faithful churchmen. One of his fiercest enemies was Bracciolini, who pointed out errors of style in Valla's works and made ad hominem attacks on Valla, accusing him of degrading vices.

Bracciolini attacked Valla's major work on Latin language and style, in which Valla argued that biblical texts could be subjected to the same analysis and critiques on the basis of style the way non-biblical classical texts could. Bracciolini argued that the new humanism was to be considered separate from theology, and profane and sacred writings were to be treated differently. He penned five Orationes in Laurentium Vallam ("Orations to Lorenzo Valla") criticizing him, which was countered by Valla writing Antidota in Pogium ("Antidote to Poggio").

Surprisingly, the two men were reconciled, prompted by other scholars and humanists. They acknowledged each other's talents, and became friends. Erasmus considered Valla superior to Bracciolini, saying Poggio was "a petty clerk so uneducated that even if he were not indecent he would still not be worth reading, and so indecent that he would deserve to be rejected by good men however learned he was." (Erasmus had probably seen and disapproved of Bracciolini's joke book.)

Although never became an apostolic secretary, he was invited to Rome by Pope Nicholas V to work on a special project: the new Vatican Library. Let's talk about that place tomorrow.

The Early Modern Period

I've offered my own idea of when the Middle Ages ended, but of course there are other ways to look at it. I suggested specific events taking place in or around 1453, but we can look at the Middle Ages not just about specific events so much as it was about cultural norms.

At the foundation of this question—and all discussions about periods in history—is whether you can accurately establish periodization at all. One of the first to "break up" the flow of events was Leonardo Bruni, mentioned as a tutor of Lorenzo Valla. Bruni has been called the first modern historian, and was the first to define human history as three periods: Antiquity, Middle Ages, and Modern. He was influenced by Petrarch, who described the glorious Classical Roman period versus the post-Classical tenebrae or "darkness." (This may have been the origin of the popular modern term "The Dark Ages.")

For Bruni to describe "Modern" as his lifetime (c.1370 - 1444) may cause us to smile, but of course it was modern to him...and may in fact still be considered the start of the Modern Era. Was there a shift in something in the 1400s that allows us to think of it as the start of our own era?

What trends or cultural shifts were significant enough—and continuous enough—to motivate modern historians to say that the Modern Era started in the 1400s? What was so different? We talk about the Renaissance as a rebirth of art and culture, but there was more:

•Globalization, with the expansion of mercantilism and sophisticated international economics
•The Age of Exploration/Discovery, with increased travel and improved methods of transport
•Religious dissent, and the development of secular policy
•The decline of feudalism, and the development of civic politics

The point is not just that these were different from what came before, but that these changes are still in place. Many of the changes that started in the 1400s are still with us, making the argument that what makes us "modern" and not "medieval" has in fact been going on for about six centuries, not just two or three.

A modern medievalist named Nancy Partner once said that if Medieval Studies wanted more respect from historians in general, they should start calling the Middle Ages the "Really Early Modern Era." Well, that may be stretching it, or maybe not, at least when it comes to the English language. Of the 1000 words most commonly used in Modern English, 83% come from Old English. Tomorrow I'll give you one idea of how much Old English you are speaking on a daily basis.

Lorenzo Valla--Early Modern Scholar

Lorenzo Valla was born about 1407 in Rome. His father was a lawyer for the pope. Lorenzo studied under Leonardo Bruni (sometimes called the first modern historian) and Giovanni Aurispa (who is credited with the revival of Greek in Italy).

Lorenzo entered the priesthood in 1431, seeking a position as a secretary in the Vatican's diplomatic office. Failing to secure that position, he went to Pavia to lecture, but he got himself in trouble there by offending the greatest jurist and expert on Roman law, Bartolus de Saxoferrato, by criticizing his Latin style. He had to leave Pavia, and became essentially an itinerant lecturer, traveling from city to city seeking opportunities at universities, until he was invited to Rome by Pope Nicholas V to work in Nicholas' new Vatican Library.

With steady employment, he could devote his spare time to writing. He had published in 1433 his first literary work, De Voluptate ("On Pleasure"), in which he argued for the benefit of Epicurus' embracing of natural appetites over the principles of the Stoics. He now produced a text on logic, Repastinatio dialectice et philosophie ("Re-digging dialectic and philosophy"). There are more: Notes on the New Testament, De Elegantis which examined Latin grammar and style, a work on Free Will that argued against Boethius' Consolation of Philosophy.

The truly ground-breaking work, however, was De falso credita et ementita Constantini Donatione declamatio, ("Declamation of the falsely believed and falsified Donation of Constantine") in 1440. The Donation of Constantine was largely believed (argued against, but still believed) as the foundation for papal authority over temporal lords.

Lorenzo took a close look at the text of the document that purported to be a formal imperial decree from the 4th century. His extensive familiarity with the development of Latin over the centuries helped him realize it was written in a style more appropriate to a less-educated writer from the 8th century.

Not only was the language wrong for the premise, he argued three other points:

1. There was no legal authority by which Emperor Constantine could have given Pope Sylvester I the powers claimed in the document.

2. There was no historical evidence in any records that there were administrative changes in the Western Roman Empire.

3. His own doubt that Constantine cared enough about the pope to give him anything.

The Church, understandably, rejected this theory. 

Lorenzo was put on trial by the Inquisition in 1444, ostensibly for supporting Alfonso V of Aragon in a territorial dispute over the Papal States.

Lorenzo Valla died 1 August 1457. It did not get formally published until 1517 and became popular among Protestants. Thomas Cromwell had it translated into English in 1534. The Donation eventually became recognized by all as a fake.

So why did I title this with the phrase "Early Modern Scholar"? Shouldn't he be labeled "Renaissance Scholar"? Many historians refer to the Renaissance as "Early Modern" now; the reasons why I look forward to explaining tomorrow.

The Donation Hoax

The Donatio Constantini (Latin: "Donation of Constantine") was a document in which the converted Emperor Constantine, whose Edict of Milan ended Christian persecution, gave the popes authority over the western part of the Roman Empire.

The 5th-century "Legend of St. Sylvester" tells about the relationship between Constantine and Pope Sylvester I. In it, Sylvester cures Constantine of leprosy, who then converts to Christianity. Following this, Constantine grants to Sylvester authority over Rome, Antioch, Alexandria, Constantinople, Jerusalem, and all churches, as well as any estates that are attached to churches. The oldest manuscript of the story is from the 9th century, but it is not until Pope Leo IX (pope from 1049 - 1054) that it gets used to affirm the supremacy of the papacy over temporal lords. It became a valuable tool in the argument, especially with the Holy Roman Emperors, that the pope's decisions and decrees superseded anyone else's. There was plenty of legal opposition to the idea, especially starting with Otto III, but no one denied its authenticity.

Then, in 1440, a Catholic priest named Lorenzo Valla took a close look at the document. He was a specialist in Latin translation, and something about the document did not look right. His familiarity with numerous Latin documents of all types and all times led him to the conclusion that, rather than an official document from the 4th century, it was a poorly written forgery from the 8th century, and therefore a hoax. 

Why was he motivated to chop down the chief pillar of papal authority over secular powers, when he himself as a priest could benefit? He might have had a personal reason, which I will look into and share next time.
