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.

Battle of Marino

Bloody fight that entrenched rival factions in Catholic Church

Robert of Geneva, rival
pope to Urban VI

Giacomo Orsini, a member of the Orsini family of Rome that produced five popes between the eighth and 18th centuries, stormed the Castle of Marino - in the area south of Rome known as the Castelli Romani - on this day in 1379, bringing a decisive conclusion to a military battle that would end any hopes that the 1378 split in the Catholic Church might be quickly resolved.

The Battle of Marino was fought between armies loyal to Pope Urban VI, the former Archbishop of Bari who had been elected as successor to Pope Gregory XI, and the antipope Clement VII, who had set up rival courts a year earlier following the split that became known as the Great Schism or Western Schism.

The papacy had only just been returned to Rome by Gregory XI from Avignon in France following a fragmentation that had occurred 70 years earlier but the election of Bartolomeo Prignano to rule as Urban VI reignited the division.

Urban VI was hostile toward the French cardinals who had gained significant power during the Avignon years and wanted the papal court to remain in the city in southeastern France.

Those cardinals, fearing that they would become marginalised, responded by declaring that Urban VI’s election was invalid due to having taken place in a climate of fear and instead elected Robert of Geneva to lead the church as Pope Clement VII.

The two rival factions assembled armies. The troops backing Urban VI were mainly Italian mercenaries under the command of Alberico da Barbiano, while the anti-papal army consisted of French mercenaries led by the Count of Montjoie.

south of Rome, as it looks in the present day

They faced each other in the Battle of Marino, fought in the valley east of the town that is now known as the Valley of the Dead, perhaps on account of the bloody battle fought there.

Victory went to the Italians, the battle concluded when the Castle of Marino - on the site of  which the Palazzo Colonna now stands - was besieged by papal troops. The fact that the castle was commanded by Giordano Orsini, a supporter of the antipope, yet the papal soldiers who took it on June 2, 1379 were led by Giordano's son Giacomo, illustrates how the split in the church also divided families. 

Following the defeat of his army, Clement VII, who had based himself in Anagni, 72km (45 miles) southeast of Rome, felt vulnerable and fled Anagni first for Sperlonga, then Gaeta, finally landing in  Naples.

He was received well by Queen Joanna I of Naples, who afforded him great respect, but in the streets he found himself confronted by angry mobs declaring their support for “Papa Urbano". He returned to Gaeta, where he boarded a ship that would ultimately take him to Avignon.

The Western Schism, also known as the Great Schism, would last from 1378 to 1417, a tumultuous period in which there were two - later three - rival popes, each claiming to be the legitimate pontiff.

The division was finally ended by The Council of Constance, which met over a period of four years between 1414 and 1418, eventually finding a mutually acceptable pope in Oddone Colonna, a Roman, who was elected as Pope Martin V.

Travel tip:

Marino today is a town in Lazio, set among the Alban Hills, 21 km (13 miles) southeast of Rome, with a population of 37,684. It is bounded by the towns of Castel Gandolfo, Albano Laziale, Rocca di Papa, Grottaferrata, and Ciampino.  Marino is famous for its white wine, and for its Grape Festival, which has been celebrated since 1924.  Marino suffered extensive damage during World War Two. In 1944 it was heavily bombed by aircraft from the United States Air Force and in the spring of 1945 it was the scene of heavy fighting between troops of the British Indian Army and Axis troops which caused much of the city to be destroyed.  As well as the Palazzo Colonna, built on the site of the former castle, Marino's  main sights include the Basilica of San Barnaba, built in Baroque style, with an imposing façade dating to 1653. Among other works of art, it houses the Martyrdom of St. Bartholomew by Guercino and a bust of St. Anthony Abbot by Ercole Ferrata.

The former palace of Boniface VIII in the
town of Anagni, which has produced four popes

Travel tip:

Anagni is an ancient town in the province of Frosinone in Lazio, built on a hillI above the Sacco Valley, southeast of Rome. It is in an area known as Ciociaria, named after the primitive footwear - ciocie - favoured for many years by people living in the area. It was a papal residence in the Middle Ages and the birthplace of no fewer than four popes: Innocent III, Gregory IX, Alexander IV, and Boniface VIII. With the death of Boniface VIII, the power of the town declined. The mediaeval Palace of Boniface VIII is near the Cathedral. Among sights worth seeking out is the majestic cathedral of Santa Maria Annunziata, built with a mix of Romanesque and Gothic styles and completed in 1104, which stands out as a city’s symbol and seat of the local diocese, with a steeple about 30m (98ft) high. The crypt of San Magno is sometimes called the 'Sistine Chapel of the Middle Age', owing to its  fresco cycle with images telling about the genesis of the world, the creation of humans and their salvation, as well as the lives and miracles of the Saint and other martyrs.

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.

Francesca Romana, near the Roman Forum

Travel tip:

The church of Santa Maria Nuova, where Pope Gregory XI is buried, adjoins the Roman Forum and is now known as the Basilica di Santa Francesca Romana, off the piazza of the same name. The tomb of Pope Gregory XI is in the south transept of the church and was reconstructed in 1584 to a design by Per Paulo Oliviero.
