Baldassare Cossa – Antipope

The colourful career of a pirate who became a pope

Baldassare Cossa, who reigned as Pope for five years under the name of John XXIII, was deposed as pontiff on this day in 1419. Stripped of his powers, he had been accused of charges that included piracy, rape, and incest, but he was still later appointed Cardinal Bishop of Frascati by a subsequent pope, Martin V.

Cossa is now known in history as an Antipope, because he was appointed as John XXIII during the Western Schism, a split within the Catholic church in the 14th and 15th centuries. 

Bishops in Rome and Avignon, France, were simultaneously claiming to be the true Pope and were eventually joined by a line of Pisan claimants, from which Cossa was appointed.

The papacy had resided in Avignon since 1309, when Rome was wracked by political chaos and violence, but Pope Gregory XI returned it to Rome in 1377. The Catholic church split in September 1378, when, following Gregory XI's death and Urban VI’s subsequent election, a group of French cardinals declared the election invalid and elected Clement VII, who claimed to be the true pope. 

As Roman claimant, Urban VI was succeeded by Boniface IX, Innocent VII and Gregory XII. Meanwhile, Clement VII was succeeded as Avignon claimant by Benedict XIII.

Following several attempts at reconciliation, the Council of Pisa declared that both Gregory XII and Benedict XIII were illegitimate and elected a third pope, Alexander V. 

The Schism was finally resolved when Cossa, who succeeded Alexander V as John XXIII, was deposed, and Pope Martin V was elected.

Cossa had been born on the island of Procida in the Bay of Naples. After following a military career, he fought in a war on the side of Naples. It has been claimed that he started out in life as a pirate and that his two brothers were sentenced to death for piracy by King Ladislaus of Naples.

After studying Law at the University of Bologna, Cossa entered the service of Pope Boniface IX in 1392. 

He later became a canon and an archdeacon in Bologna and then Cardinal Deacon and a papal legate in Romagna. He is remembered as being unscrupulous and immoral and leading a depraved life, seducing countless women. It was also claimed he had links with local robber bands that were used to intimidate his rivals and attack carriages, and that these connections helped him achieve power and influence in the region.

As a Cardinal, he was a leading figure at the Council of Pisa that deposed Gregory XII and Benedict XIII, and elected Alexander V. Because both Gregory and Benedict ignored the council’s decision, it meant there were then three simultaneous claimants to the papacy.

Alexander V died while he was with Cossa in Bologna in 1410. Cossa was quickly ordained as a bishop and consecrated as Pope the following day, taking the name John XXIII.

The new pope made the Medici Bank the official bank of the papacy, which contributed considerably to the wealth of the family.

John XXIII’s main enemy was King Ladislaus, who was still protecting the Roman claimant, Gregory XII, so he joined forces with Louis II of Anjou against him. But Ladislaus took Rome in 1413, forcing him to flee to Florence.

While in Florence, John XXIII met Sigismund of Luxembourg, who wanted to end the Schism and urged him to call for a General Council.  The resulting Council of Constance resolved that all three papal claimants should abdicate and a new pope should be elected. 

John XXIII escaped from Constance disguised as a postman. But he was later deposed by the council and tried in his absence on charges of piracy, rape, sodomy, murder, and incest. After he was caught in Germany and given up to Ludwig III Elector Palatine, he was imprisoned for a few months until a large ransom was paid for his release by the Medici.

Martin V then made Baldassare Cossa the Cardinal Bishop of Frascati, but Cossa died a few months later in 1419 in Florence. The Medici had a magnificent tomb created for him by Donatello and Michelozzo in the Battistero di San Giovanni, which was inscribed, ‘John the former pope’ - despite protests by Martin V.

After Angelo Roncalli from Bergamo was elected pope in 1958, there was confusion over whether he would be called John XXIII or John XXIV, but the new pope declared himself John XXIII to put the question to rest for good, and Baldassare Cossa is now remembered as Antipope John XXIII.

notable for its houses painted in pastel colours

Travel tip:

Procida, the island off the coast of Naples where Antipope John XXIII was born, lies next to the larger island of Ischia and is just a short boat trip from Naples. Procida is less than 4km (2½ miles) long and 2km (1¼ miles) across at its widest point. It has a pretty seafront with yellow, white, and pink painted houses. The ferries arrive and depart from Marina di San Cattolico, where there is a tourist office and bars and restaurants. The small islet of Vivara is attached to the island by a walking bridge. No one lives there and it is now a nature reserve. Around Procida are dark sandy beaches suitable for sunbathing and swimming in the sea. The main church on the island is San Michele Arcangelo which has many old statues and religious paintings. On the main ceiling is Luca Giordano’s The Glory of San Michele. In the apse is Nicola Rosso’s painting San Michele Defending the Island, showing the saint with sword and shield above Procida, which is surrounded by shiploads of Turkish invaders.

Frascati's main church is the Cattedrale di
San Pietro, completed in the 18th century

Travel tip:

Frascati, where Antipope John XXIII was appointed as Cardinal Bishop, is an ancient, wine-producing city to the south of Rome. It has the feel of Rome, but it is on a smaller scale and life is at a less frantic pace. There are statues, fountains, and wonderful architecture, but it is easy to walk around in Frascati. It is said that Frascati’s eponymous white wine ‘non viaggia bene’ (does not travel well), which is all the more reason to drink it there, in quaint wine bars serving it cheaply by the glass. Villas built by wealthy Romans on the hills behind Frascati now lie in ruins, but there are elegant 16th and 17th century villas, such as the imposing Villa Aldobrandini, to look round. In the centre of Frascati, the 16th century Chiesa del Gesù has statues on the façade believed to be the work of Pietro da Cortona and frescoes inside by Andrea Pozzo. Piazza del Gesù leads into the larger Piazza San Pietro, where Frascati’s main church, Cattedrale di San Pietro stands. Inside the church is the tombstone of Charles Edward Stuart, also known as Bonnie Prince Charlie or the Young Pretender. He died while in exile in Rome and was first buried in Frascati’s cathedral, where his brother, Henry Benedict Stuart, Duke of York, was Bishop. In 1807 his body was moved to St Peter’s in Rome, but his heart was left in Frascati, in a small urn, under the floor below his monument. Within a few streets in Via dell’Olmo, is the Osteria dell’Olmo, one of Frascati’s oldest osterie, where you can taste Frascati wine and typical local dishes.

Saint Catherine of Siena

Pious woman from ordinary family helped the Pope reorganise the church

 the Kunsthistorisches Museum in Vienna

Caterina Benincasa, who was one day to be canonized as Saint Catherine of Siena, a patron saint of Rome, Italy and Europe, was born on this day in 1347 in Siena in Tuscany.

She is remembered for her writings, all of which were dictated to scribes, as she did not learn to write until late in life. While carrying out Christ’s work in Italy, she wrote about 380 letters, 26 prayers, and four treatises of Il libro della divina dottrina, better known as The Dialogue. These works were so influential and highly regarded she was later declared a Doctor of the Church.

Caterina was the youngest of 25 children born to Lapa Piagenti, the daughter of a poet, and Jacopo di Benincasa, a cloth dyer. She is said to have had her first vision of God when she was just five years old and at the age of seven, Caterina vowed to give her whole life to God.

She refused to get married when her parents tried to arrange it, cut off her hair to make herself look less attractive and began to fast. She did not want to take a nun’s veil, but to live an active life full of prayer in society, following the model of the Dominicans.

When she was in her early 20s, Caterina said she had experienced a spiritual espousal, or mystical marriage, to Christ, and she began serving the poor and sick in Siena and attracted a group of followers.

She started to travel around Italy to promote church reform. She strongly believed the return of Pope Gregory XI to Rome was the best way to bring peace to Italy and she went to Avignon to be an unofficial advocate of this. She was then sent by him to negotiate peace with Florence.

In 1377 she founded a women’s monastery of strict observance in an old fortress outside Siena.

The next Pope, Urban VI, invited Caterina to Rome to help reorganise the church. She lived at the court meeting individual nobles to convince them to support the Pope and sending letters to other princes and cardinals urging them to obey him.

She tried to win back the support of Queen Joan I of Naples for the papacy, although Urban VI had previously excommunicated the queen for supporting the antipope. Being trusted by the Pope with such important work was rare for a woman in the Middle Ages.

By the time Caterina was 33 her habit of extreme fasting, eventually living just off the daily Eucharist, had made her ill. She became unable to eat and drink at all and lost the use of her legs. She died on 29 April, 1380 following a stroke. Her last words had been: ‘Father, into Your Hands I commend my soul and my spirit.’

Holy Family, is in the Accademia Carrara in Bergamo

Pope Urban VI celebrated her funeral and her burial in the Basilica of Santa Maria Sopra Minerva near the Pantheon in Rome. Her head and thumb were later entombed in the Basilica of San Domenico in Siena, where they remain.

Caterina had a spiritual adviser and friend from about 1374 until her death named Raymond of Capua. He wrote what is known as the Legenda Major: a Life of Caterina, which was completed in 1395.

Tommaso Caffarini, also known as Thomas of Siena, wrote an account of Caterina’s life and compiled a set of documents with testimony from many of her disciples as part of the process for her canonisation. An anonymous Florentine wrote Miracoli della Beata Caterina, about the miracles she performed.

The devotion to Caterina di Siena grew rapidly after her death. She was canonised in 1461 by Pope Pius II, who was himself from Siena and her feast day was established on 29 April. She was declared patron saint of Rome in 1866 and of Italy, together with St Francis of Assisi, in 1939. She was proclaimed patron saint of Europe in 1999 by Pope John Paul II.

Caterina’s Dialogue, letters and prayers have given her a prominent place in the history of Italian literature.

Caterina's home in Siena is now a shrine, which
houses a museum dedicated to her life

Travel tip:

Siena in Tuscany, where Caterina was born and lived for much of her life, has made a shrine out of the house she lived in with her parents. It has a museum dedicated to her life and is open to visitors in Vicolo di Tiratolo off Costa Sant’Antonio.  The nearby Basilica of San Domenico has a Cappella Santa Caterina where her head and thumb are housed. Siena is the venue for the historic horse race, the Palio di Siena. The race is contested in Siena’s Piazza del Campo, a shell-shaped open area which is regarded as one of Europe’s finest medieval squares. It was established in the 13th century as an open marketplace on a sloping site between the three communities that eventually merged to form the city of Siena.

The Basilica of Santa Maria Sopra Minerva
in Rome, which houses Catherine's remains

Travel tip:

Caterina was buried in the Basilica of Santa Maria Sopra Minerva, which is in Piazza Minerva, close to the Pantheon in Rome. The basilica is the only surviving Gothic church structure left in Rome and has the original, arched vaulting inside. A sarcophagus containing the remains of Saint Catherine of Siena can be seen behind the high altar.  Among the works of art in the church are Michelangelo's statue Cristo della Minerva (1521) and the late 15th-century (1488–93) cycle of frescoes in the Carafa Chapel by Filippino Lippi. The basilica also houses the tomb of the 15th century the Dominican friar Fra Giovanni da Fiesole (Blessed John of Fiesole, born Guido di Piero) better known as the painter Fra Angelico.

Election of Pope Clement VII

Appointment that sparked split in Catholic Church

Pope Clement VII, a portrait by the 19th
century French painter Henri Serrur

The election of Robert of Geneva as Pope Clement VII by a group of disaffected French cardinals, prompting the split in the Roman Catholic Church that became known as the Western Schism or the Great Schism, took place on this day in 1378.

The extraordinary division in the hierarchy of the church, which saw two and ultimately three rival popes each claiming to be the rightful leader, each with his own court and following, was not resolved until 1417.

It was prompted by the election in Rome of Urban VI as the successor to Gregory XI, who had returned the papal court to Rome from Avignon, where it had been based for almost 70 years after an earlier dispute.

The election of Cardinal Bartolomeo Prignano as Urban VI followed rioting by angry Roman citizens demanding a Roman be made pope. Prignano, the former Archbishop of Bari was not a Roman - he was born in Itri, near Formia in southern Lazio - but was seen as the closest to it among those seen as suitable candidates.

His appointment was not well received, however, by some of the powerful French cardinals who had moved from Avignon to Rome, who claimed the election should be declared invalid because it was made under fear of civil unrest. They decided to leave Rome and set up a rival court at Anagni, the city 70km (43 miles) southeast of Rome famous for producing four popes during the 13th century and a popular summer residence for popes through several centuries.

Pope Urban VI was elected after Roman
 citizens rioted in the streets 

They chose Robert of Geneva, who had been living in England as rector of Bishopwearmouth in County Durham, having previously been Archdeacon of Dorset.

He had acquired the unfortunate nickname of ‘butcher of Cesena’ following his decision to command troops lent to the papacy by the condottiero John Hawkwood to put down a rebellion there. Between 3,000 and 8,000 civilians were killed.

Yet he had the support of Queen Joanna of Naples and Charles V of France and set up his court in Avignon.

The double election was a disaster for the church. The followers of the two popes tended to be divided along national lines, and thus reinforced the political antagonisms of the time.  France, Aragon, Castile and León, for example, recognised Clement VII, but the German-dominated Holy Roman Empire sided with Urban VI.  England pledged its allegiance to Urban VI, but Scotland and Wales saw Clement VII as the legitimate pope.

The spectacle of rival popes denouncing each other in public was enormously damaging for the papacy but resolving the split took almost 40 years.

The election of Pope Martin V
in 1417 ended the schism

Pope Boniface IX succeeded Urban VI in 1389 and Benedict XIII followed Clement VII in reigning from Avignon from 1394. A request from Rome on the death of Pope Boniface in 1404 that Benedict resign was rejected and the Roman faction elected Pope Innocent VII.

In 1409, after 15 sessions, a church council convened at Pisa attempted to solve the schism by deposing both Pope and antipope but added to the problem by electing a second antipope, Alexander V, who was succeeded by antipope John XXIII.

Finally, a council was convened by John XXIII in 1414 at Constance, which secured the resignations of John XXIII and Pope Gregory XII. Benedict XIII refused to step down but was excommunicated. The Council elected Pope Martin V in 1417, essentially ending the schism.

The line of Roman popes is now recognized as the legitimate line. Gregory XII's resignation was the last time a pope resigned until Benedict XVI, who stepped down in 2013, aged 86, on the grounds of advancing years.

The remains of Itri's castle are worth a visit

Travel tip:

Itri is a small city in the province of Latina, Lazio, about 100km (62 miles) north of Naples and 150km (96 miles) south of Rome. It lies in a valley between the Monti Aurunci and the sea, not far from the Gulf of Gaeta.  Although the city suffered damage during the Second World War, the remains of its castle, which commands the valley, are worth visiting. On March 19 of each year, the people of Itri celebrate the feast of Saint Joseph, at which traditionally large bonfires are ignited, around which people dance and sing and eat the traditional “zeppole di San Giuseppe”, cakes formed from a dough made with sugar and eggs which is fried and coated with honey.

The Palazzo dei Papi in Agnani was the summer
residence of many popes

Travel tip:

Anagni is an ancient town in the province of Frosinone in Lazio. It is southeast of Rome in an area known as Ciociaria, named after the primitive footwear - ciocie - favoured for many years by people living in the area. Boniface VIII was the fourth Pope produced by Anagni but after his death the power of the town declined as the papal court was transferred to Avignon. The medieval Palace of Boniface VIII is near the Cathedral.

Baldus de Ubaldis – lawyer

Legal opinions have stood the test of time

Baldus de Ubaldis wrote more than 3,000
legal opinions during his career

An expert in medieval Roman law, Baldus de Ubaldis, died on this day in 1400 in Pavia.

De Ubaldis had written more than 3,000 consilia - legal opinions - the most to remain preserved from any medieval lawyer.

His work on the law of evidence and gradations of proof remained the standard treatment of the subject for centuries after his death.

De Ubaldis was born into a noble family in Perugia in 1327. He studied law and received the degree of doctor of civil law when he was 17.

He taught law at the University of Bologna for three years and was then offered a professorship at Perugia University where he remained for 33 years.

De Ubaldis subsequently taught law at Pisa, Florence, Padua, Pavia and Piacenza.

He taught Pierre Roger de Beaufort, who became Pope Gregory XI, whose immediate successor, Urban VI, summoned De Ubaldis to Rome in 1380 to consult with him about the anti-pope, Clement VII. The lawyer’s view on the legal issues relating to the schism are laid down in his Questio de schismate.

One of the best works of De Ubaldis is considered to be his commentary on the Libri Feudorum, a compilation of feudal law provisions.

The old Roman aqueduct in Perugia is now a street

Travel tip:

Perugia, where De Ubaldis was born, the capital of the region of Umbria, is a large city on a hill, established during the Etruscan period. The University of Perugia, where De Ubaldis taught law, today welcomes many foreign students. The city hosts an annual jazz festival and an annual chocolate festival.

The facade of the Certosa in Pavia

Travel tip:

Pavia, where De Ubaldis died, is a city in Lombardy, about 46km (30 miles) south of Milan, known for its ancient university, which was founded in 1361, and its famous Certosa, a magnificent monastery complex north of the city that dates back to 1396. A pretty covered bridge over the River Ticino leads to Borgo Ticino, where the inhabitants claim to be the true people of Pavia and are of Sabaudian origin.

Pope Gregory XI returns the papacy to Rome

Important date in Roman and papal history

Pope Gregory XI was the last French pope
and the last to rule from Avignon

The French Pope, Gregory XI, returned the papacy to Rome, against the wishes of France and several of his cardinals, on this day in 1377.

The move back to Rome was a highly significant act in history as the papacy, from that date onwards, was to remain in the city.

Gregory was born Pierre-Roger De Beaufort in Limoges. He was the last French pope, and he was also the last pope to reign from Avignon, where he had been unanimously elected in 1370.

He immediately gave consideration to returning the papacy to Rome in order to conduct negotiations for reuniting the Eastern and Western Churches and to maintain papal territories against a Florentine revolt being led by the powerful Visconti family.

But Gregory had to shelve his Roman plan temporarily in order to strive for peace between England and France after another phase in the Hundred Years’ War started.

However, in 1375, he defeated Florence in its war against the Papal States and the following year, he listened to the pleas of the mystic Catherine of Siena, later to become a patron saint of Italy, to move the papacy back to Rome.

of Catherine of Siena with Gregory XI at Avignon

After peace was concluded against Florence, Gregory returned the papal court to Rome, entering the city on 17 January 1377, ending nearly 70 years of popes residing in Avignon.

His last few months in Rome were marred by conflict and at one stage he had to flee to Anagni, a town outside the city. Gregory died in March 1377 in Rome and was interred in the church of Santa Maria Nuova.

But the move back to Rome he brought about was important in papal history. Since then, the papacy, despite the reigns of antipopes in other cities, has always remained in Rome.

After Gregory’s death, the College of Cardinals was threatened by a Roman mob that broke into the voting chamber to try to force an Italian pope into the papacy.

The Italians chose Urban VI, but the Cardinals were against him and withdrew to Fondi, the city between Rome and Naples that was the home of the powerful Caetani family, where they annulled the election of Urban and elected a French pope, Clement VII.

This election of rival popes caused the split known as the Western Schism, forcing Europe into a dilemma about papal allegiance.

The Schism was not resolved fully until the Council of Constance was held by the College of Cardinals between 1414 and 1418. The Council deposed both popes and elected the Roman-born Martin V.

After a long stay in Florence, Martin V entered Rome in 1420 and immediately set to work restoring order and repairing dilapidated churches and palaces.

The papal residence in Anagni was a retreat for many
popes seeking refuge from Rome

Travel tip:

Anagni, where Pope Gregory XI briefly sought refuge, is an ancient town in the province of Frosinone in Lazio. It is south east of Rome in an area known as Ciociaria, named after the primitive footwear, ciocie, a type of sandal, worn by people living in the area. During medieval times many popes chose to reside in Anagni, considering it safer and healthier than Rome. The town produced four popes, the last one being Boniface VIII, who was hiding out there in 1303 when he received the famous Anagni slap, delivered by an angry member of the fiercely antipapal Colonna family after he refused to abdicate. After his death the power of the town declined and the papal court was transferred to Avignon. The medieval Palace of Boniface VIII, is near the Cathedral in the centre of the town. Close by there is a restaurant named Lo Schiaffo - The Slap.
