DAL CAOS ALLA RIPRESA

Nel Quattrocento la struttura di Roma si trasforma radicalmente.
1424 - Il santo frate
fa bruciare le streghe sul Campidoglio


19 dicembre 1424 -
Strage di pellegrini
a ponte Sant'Angelo

Molti storici dell’arte sostengono che il Rinascimento sia cominciato a Firenze con la riscoperta della poesia latina e greca, e che solo in seguito si sia esteso alle arti visive. Papa Martino V Colonna (1417 - 31), con il suo ambizioso programma di ricostruzione degli edifici dell’antica Roma e delle chiese dei primi secoli del Cristianesimo, è considerato l’iniziatore del Rinascimento romano. La cultura umanistica esce dalla ristretta cerchia di artisti e letterati: attraverso l'architettura, le opere d'arte e le nuove idee della "città ideale", l'umanesimo finisce per conquistare gli stessi ambienti ecclesiastici sino ai papi che chiamano a Roma i più grandi artisti.

1438 - Furto di reliquie al Laterano
1431 - 1447 - E' papa Eugenio IV Condulmer

1447 - 1455 - Diventa papa Niccolò V Parentucelli. E' il primo vero papa umanista. Egli avvia un vasto programma di revisione urbanistica in base al quale fa demolire la vecchia basilica petriana e affida al Rossellino il compito di costruirne una nuova. Leon Battista Alberti inizia la costruzione dei Palazzi Vaticani, vengono quindi ristrutturati i borghi e si edifica il nuovo Palazzo dei Conservatori sulla piazza capitolina.
Molti restauri e iniziative edilizie vengono intraprese in occasione dell'anno santo del 1450, quando viene creato un nuovo tessuto viario, non più in funzione dei vecchi centri di rappresentanza (Fori, Campidoglio, Laterano), ma del Vaticano.

Il Grande Scisma

Papa Gregorio IX had left instructions that a conclave should be held immediately after his death: most of the cardinals were French, but some of them remained in Avignon and did not participate in the conclave; as the rumour spread that a French cardinal had been elected pope, a mob of Romans made their way into the Vatican and so frightened the cardinals that they announced the false election of a Roman pope. Ten days later they eventually announced the appointment of the archbishop of Bari, who became Pope Urban VI. At the beginning the French cardinals, including those who had not attended the election, accepted the new pope, but a few months later, because the pope refused to move yet again the papal court to Avignon, they met at Anagni and declared void Pope Urban's election, because it had been influenced by the Romans. They elected a new pope, Cardinal Robert de Genevois, who had earned a reputation for the massacre of Cesena. In April 1379 the mercenary troops of the two popes clashed at Marino and the French (Anti)Pope Clement VII was forced to flee to Avignon where he was regarded as the legitimate pope.
This was the beginning of a period of great confusion which is known as the Great (Western) Schism. The Rome and the Avignon popes continued to quarrel for years about who was the legitimate successor of St. Peter and at their death the schism continued with their successors Boniface IX in Rome and Benedict XIII in Avignon.
Pope Boniface IX in an attempt to strengthen his position legitimated the rule of the local lords in the towns of the northern part of the papal state in return of financial and military support: Urbino, one of these towns was to become one of the key centres of the Renaissance. The pope took advantage of the 1400 Jubilee year to replenish the finances of the Papal State and his own: the selling of indulgences (papal grants of remission of the temporal punishment in purgatory) was of such magnitude that even the kings who supported him, declared their dissatisfaction with his behaviour.

During the Great Schism the popes had little time and resources to devote to the development of Rome: Pope Urban VI spent many years in Naples and other towns of that region under the protection of the King of Naples; Pope Boniface IX managed to reside in Rome where he strengthened Castel Sant'Angelo and he built a tall tower to protect Palazzo Senatorio. He also took care of improving the fortresses which controlled the access to Rome: his coat of arms can be seen on the tallest tower of the fortress of Narni.

Il Concilio di Costanza

Nel 1406, dopo la morte di Papa Bonifacio IX e il breve pontificato di Papa Innocenzo VII, i cardinali prima di entrare in conclave stabilirono che il nuovo eletto should commit to abdicate if the Avignon pope did the same with the aim of paving the way to the end of the schism. They elected Pope Gregory XII, aged 83, who initially acted to find an agreement with his opponent; the members of his family however put pressure on him to delay his abdication.
Negotiations between the two parties dragged on inconclusively for some time until a group of cardinals (and bishops) both from Rome and Avignon met in 1409 in Pisa and declared that both Pope Gregory XII and (Anti)Pope Benedict XIII were deposed. Although the cardinals had the support of many kings the Pope they elected (Alexander V) did not achieve a general consensus: so the purpose of the so-called Council of Pisa was not met and the confusion increased with three popes claiming to be the legitimate successor of St. Peter. Pope Alexander V passed away in 1410 most likely poisoned by Cardinal Baldassarre Cossa who arranged a hasty conclave which appointed him Pope John XXIII (Note: while Pope Alexander V was considered a legitimate pope by Cardinal Borgia who at his election in 1492 became Pope Alexander VI, the same did not occur to Pope John XXIII in 1958 when the elected pope (Cardinal Angelo Roncalli) chose to call himself Pope John XXIII, by this meaning that his predecessor by the same name had not been a legitimate pope).
In 1413 the German emperor Sigismund of Luxemburg took the initiative to convene an ecumenical council in the town of Constance in southern Germany: the invitation was not limited to the cardinals, but was extended to bishops and representatives of the monastic orders as well as to representatives of the five European nations: Germany, England, France, Italy and Iberia: the Council can be regarded as a forerunner of the great European conferences of Westphalia (1648), Aix-la-Chapelle (1748) and Vienna (1815). The Council opened in November 1414 and on July 1415 it was authorized by Pope Gregory XII, who at the same time resigned from the papal throne. The Council forced the other two contenders to resign; the assembly chose to delay the election of a new pope until it had reviewed many aspects of the roles and authorities of the pope, the cardinals, the bishops and the ecumenical council, including the financial aspects of the ecclesiastical activity.

Terra di vacai (land of cowherds) were the words used by the Florentines to define Rome in the early XVth century with a reference to the cattle and goats which grazed in Campo Vaccino and Monte Caprino. There was an enormous difference between the economic and cultural situation of Milan, Venice, Florence and other Italian towns and that of Rome, where the rival popes sought the support of mercenary troops or that of the King of Naples, so that the city was pillaged in 1413 and 1417 by Neapolitan troops.

Papa Martino V

The Council of Constanza alla fine elected a new pope through a very special conclave composed of 23 cardinals and 6 representatives for each of the five nations participating in the council: the choice fell on Cardinal Oddone Colonna, a member of a very important Roman family. He chose to be called Martin V and he chaired the final sessions of the council: he had to accept several limitations to the papal authority and to promise to convene another council in 1423: both Emperor Sigismund and Charles VI, King of France asked him to reside in their countries, but Pope Martin V felt he had to return to Rome; he did so in 1420 after having ensured the appropriate political and military alliances.
The fact of belonging to a powerful family gave him the strength to rule without the interested help of kings and emperors and he also managed to control the inconclusive outcome of the council held in Siena in 1423-24. He took however the commitment to convene another council in 1431 in Basel.

Maria sopra Minerva tablet recording the 1422 flood of the Tiber (in the year 1422 on the day of St. Andrew the water of the Tiber reached the top of this tablet: placed by Pope Martin V in the VIth year of his pontificate)

Pope Martin V is regarded by some historians as the founder of modern Rome. He called a Jubilee year in 1423 to celebrate the end of the schism and to provide Rome with an opportunity to restart its economic and artistic development. The pope had sojourned for more than a year in Florence and he invited several Florentine artists to visit Rome: among them Masaccio and Masolino who painted a large polyptych (an altarpiece consisting of more than three panels) depicting the Miracolo della Neve in S. Maria Maggiore (now the panels can be seen in museums in London, Philadelphia and Naples). Frescoes by Masolino can be seen in S. Clemente. Pope Martin V restored many churches and in particular S. Giovanni in Laterano (the pavement) where he chose to be buried.
He also took care of more practical aspects of an effective administration of Rome. By entrusting to the guild of the Speziali (pharmacists) the care of S. Lorenzo in Miranda he started a process through which many churches were taken care of by associations of private citizens thus contributing to their maintenance and embellishment.
After almost a thousand years he reintroduced the magistri viarum, who were in charge of policing the streets of Rome, a first step towards a more effective town planning activity. Even the first modern recording of the Tiber floods is due to the action of this pope.

Pope Eugenius IV and the Council of Florence

Pope Martin V died in 1431 when the Council of Basel was about to start: the fourteen cardinals who were in Rome hastened to elect his successor, maybe to avoid a repetition of the 1417 conclave to which also lay representatives of the Christian nations took part. The cardinals agreed that the future pope would not take important decisions without their agreement; they then elected Cardinal Gabriele Condulmer, a nephew of Pope Gregory XII, who chose to be called Eugenius IV. His first acts were aimed at reducing the influence of the Colonna family; he then dissolved the Council of Basel just four days after its opening, causing the reaction of most of the participants who went along with their proceedings and declared that the Council authority was superior to the papal one.
Only the intervention of Emperor Sigismund avoided another schism and eventually Pope Eugenius accepted that the Council continued. In return Sigismund was crowned emperor on May 31, 1433 in
St. Peter's.
After Sigismund returned to Germany the position of Pope Eugenius IV in Rome became so weak that he was forced to flee to Florence where he placed his residence in the convent next to S. Maria Novella.
In 1438 he tried to close the Council of Basel by convening another one in Ferrara; this council, due to a pestilence, was moved to Florence where the pope was able to directly supervise its work: at the council an agreement was reached with the Orthodox church to put an end to the schism which had started in 1054. A delegation led by the Byzantine Emperor John VIII attended the council: the Florentines were very impressed by the luxury of the imperial retinue. Pope Eugenius IV reached agreements with other eastern churches; notwithstanding the fact that the Council of Basel had elected another pope, Pope Eugenius IV, through these agreements, gained such an authority that in 1443 he was able to return to Rome.


S. Pietro - Porta del Filarete: (da sinistra a destra): Papa Eugenio IV incorona l'imperatore Sigismondo; Giove (come cigno) e Leda; Giove(come aquila) e Ganymede

Papa Eugenius IV commissioned a new bronze door for S. Pietro to Antonio Averlino known as il Filarete, a young Florentine sculptor who is mainly known for his later activity as an architect in Milan. Filarete had most likely worked with Lorenzo Ghiberti whose eastern door of the Baptistery of Florence (according to Michelangelo) was fit to be that of Heaven (Porta del Paradiso).
It took 12 years to Filarete and to his assistants to complete their work which was so highly regarded that Pope Paul V made use of the door also for the new basilica.
The main panels show episodes from the lives of St. Peter and St. Paul, while smaller panels depict events of the pope's life. A very interesting detail of the door is the elaborate decoration of its frame, where Filarete portrayed the loves of Jupiter and other mythological tales.


S. Pietro - Porta del Filarete - inner side: relief showing the artist's seven assistants

Filarete portrayed himself in two small medallions and his assistants in a bronze panel placed in the lower part of the inner side of the door. The seven men are dancing for the joy of having completed such a complex work: the dance is led by Filarete's chief assistant: they all hold their tools and next to each of them we can read their names: in this door the spirit of Renaissance, with its focus on the human being, made its first Roman appearance.

The Debate about S. Pietro

On March 25, 1436 Pope Eugenius IV and the papal court attended the solemn ceremonies for the completion della cupola di S. Maria del Fiore
, la cattedrale di Firenze. Le dimensioni della chiesa costruita dagli orgogliosi Fiorentini superavano quelle di ogni altra chiesa, l'elegante campanile di Giotto stood next to it and the daring dome by Filippo Brunelleschi seemed to defy all known physical laws. Non era il fervore religioso che aveva spinto i Fiorentini a sostenere tale ingente spesa: non c'erano reliquie da adorare o santi da invocare; la cattedrale era dedicata alla Vergine Maria, ma del Fiore significava 'di Firenze', perciò era un monumento alla città, una evidenza tangibili della ricchezza e della potenza raggiunte dalla (very lay) Repubblica Fiorentina.
Il papa comprese che il primato di S. Pietro in Vaticano, la basilica Romana sulla quale poggiava l'autorità del papa, era sfidato da S. Maria del Fiore. It was the starting point of a process which eventually ended in the construction of a totally new basilica.


S. Pietro: (sopra) iscrizione riportante la lunghezza della lunghezza della cattedrale fiorentina; (sotto) Rota Constantiniana

The primacy of new S. Pietro over all the other churches is made evident by bronze stars placed in the pavement of the basilica marking the length of the largest churches in the world (the measures are taken from the apse of the basilica) . Florentina Metropolitana indicates S. Maria del Fiore, the benchmark for the construction of S. Pietro (another star closer to the entrance marks the greater length of London's St Paul's Cathedral, which was built towards the end of the XVIIth century).
Few things of the old basilica were deemed important enough to be placed in the new one: among them the circular porphyry stone (rota Constantiniana - Constantine's wheel/circle) upon which the emperors knelt during the coronation ceremonies.

Papa Niccolò V

At the death of Pope Eugenius IV, many thought the new pope would have been Cardinal Prospero Colonna, but the cardinals chose differently and elected the relatively young cardinal (aged 49) Tommaso Parentucelli, who was known for his diplomatic skills and for his wide cultural interests.
Pope Nicholas V, the new pope, had to face the hostility of the Colonna family and he sought the support of their rivals, the Orsini; after some time however he was accepted also by the Colonna. In 1449 he declared a Jubilee for the next year: he had managed to convince the last antipope to give up and recognize his legitimacy and at the same time to avoid calling other ecumenical councils which could undermine his authority, so the Jubilee year 1450 celebrated the recovery of the papal role after a very long period of crisis.
Nel 1453, la caduta di Constantinople led to the reopening of the eastern schism: in 1439 the Byzantine emperor supported the recognition of the papal supremacy in the hope of being helped in his fight for survival against the Ottomans, but the Patriarch of Constantinople who accompanied the emperor at the Council of Florence died a few days after having signed the agreement by which the schism was ended. His successor and the majority of the Orthodox clergy were unhappy about what they saw as a capitulation to the Roman thesis; Mehmet II, the sultan who conquered Constantinople, recognized the Patriarch of Constantinople as head of the Christian millet (community) living in the Ottoman Empire: in this way the patriarchs gained a de facto authority they did not have during the rule of the Byzantine emperors: the patriarchs preferred to retain their religious independence from Rome, although this meant accepting the Ottoman yoke.
Pope Nicholas V vainly tried to promote a crusade to free Constantinople. His calls did not impress the European sovereigns and not even the public in general as the fall of Constantinople had been an anticipated event for many years.


S. Maria sopra Minerva: detail of the portal and inscription and coat of arms of the Orsini

Papa Niccolò V had an ambitious plan to enable Rome to close the gap with the more advanced cities of central and northern Italy: he justified this objective by saying that the people could only understand the greatness of the Lord from the monuments celebrating his glory. His plan was based on five points:
a) the restoration of the city walls, aqueducts and bridges: a section of the walls he strengthened can still be seen between Porta S. Paolo and the Tiber: he also modernized the fortifications of Castel S. Angelo and added another tower to Palazzo Senatorio (it is shown in the image used as background for this page). He restored Acqua Vergine, one of the old aqueducts, Ponte Nomentano, Ponte Milvio, Ponte degli Angeli (damaged during the Jubilee) and Ponte Rotto (damaged by the 1422 flood).
b) the restoration of the 40 chiese stazionarie which worshippers visited during Lent: among many others it is worth citing the restoration of S. Stefano Rotondo, S. Teodoro and that of S. Maria della Minerva (paid by Francesco Orsini).
c) the redesign of Borgo which should have become a Citadel of the Faith (eventually the pope had time only to strengthen il Passetto).
d) the enlargement of S. Pietro: Leon Battista Alberti carried out a study to straighten the basilica's tottering walls and Bernardo Rossellino developed the design of a new larger apse.
e) the modernization of the papal palace adjoining the basilica: a chapel dedicated to the pope (Cappella Nicolina) is the main remaining work of art of that period: its frescoes by Beato Angelico and Benozzo Gozzoli while officially illustrating the life of St Lawrence, actually portrayed Pope Nicholas V and his court.

The pope suffered from gout and he died in March 1455 without having the time to see the completion of his plans. His pontificate marked the beginning of Modern Rome.
