Question: When did the Greek Orthodox church split from the city where the person who created the Perugia Altarpiece died?

full_context: Document 1: Fano Altarpiece: The Fano Altarpiece is a painting by the Italian Renaissance artist Pietro Perugino, executed in 1497, and housed in the church of Santa Maria Nuova, Fano, central Italy. It also includes a lunette with a "Pietà" and several predella panels.
Document 2: Southern Europe: During the Middle Ages, the Eastern Roman Empire survived, though modern historians refer to this state as the Byzantine Empire. In Western Europe, Germanic peoples moved into positions of power in the remnants of the former Western Roman Empire and established kingdoms and empires of their own.
Document 3: Fra Angelico: In 1445 Pope Eugene IV summoned him to Rome to paint the frescoes of the Chapel of the Holy Sacrament at St Peter's, later demolished by Pope Paul III. Vasari claims that at this time Fra Angelico was offered the Archbishopric of Florence by Pope Nicholas V, and that he refused it, recommending another friar for the position. The story seems possible and even likely. However, if Vasari's date is correct, then the pope must have been Eugene IV and not Nicholas, who was elected Pope only on 6 March 1447. Moreover, the archbishop in 1446–1459 was the Dominican Antoninus of Florence (Antonio Pierozzi), canonized by Pope Adrian VI in 1523. In 1447 Fra Angelico was in Orvieto with his pupil, Benozzo Gozzoli, executing works for the Cathedral. Among his other pupils were Zanobi Strozzi.
Document 4: Pietà (Perugino): Pietà is a painting by the Italian Renaissance artist Pietro Perugino, executed around 1483-1493, and housed in the Uffizi Gallery, Florence.
Document 5: Vallombrosa Altarpiece: The Vallombrosa Altarpiece is a painting by the Italian Renaissance painter Pietro Perugino, dating to 1500–01. It is housed in the Accademia Gallery of Florence, Italy.
Document 6: Western world: The geopolitical divisions in Europe that created a concept of East and West originated in the Roman Empire. The Eastern Mediterranean was home to the highly urbanized cultures that had Greek as their common language (owing to the older empire of Alexander the Great and of the Hellenistic successors), whereas the West was much more rural in its character and more readily adopted Latin as its common language. After the fall of the Western Roman Empire, Western and Central Europe were substantially cut off from the East where Byzantine Greek culture and Eastern Christianity became founding influences in the Arab / Muslim world and among the Eastern and Southern Slavic peoples. Roman Catholic Western and Central Europe, as such, maintained a distinct identity particularly as it began to redevelop during the Renaissance. Even following the Protestant Reformation, Protestant Europe continued to see itself as more tied to Roman Catholic Europe than other parts of the perceived civilized world.
Document 7: Vocation of the Apostles: The Vocation of the Apostles is a fresco by the Italian Renaissance painter Domenico Ghirlandaio, executed in 1481–1482 and located in the Sistine Chapel, Rome. It depicts the Gospel narrative of Jesus Christ calling Peter and Andrew to become his disciples.
Document 8: Perugia Altarpiece: The Perugia Altarpiece (Italian: "Pala di Perugia") is a painting by the Italian early Renaissance painter Fra Angelico, housed in the Galleria Nazionale dell'Umbria of Perugia, Italy.
Document 9: East–West Schism: In 476, when the last emperor of the western part of the Roman Empire was deposed and the western imperial insignia were sent to Constantinople, there was once again a single Roman Emperor. However, he had little power in the West, which was ruled almost entirely by various Germanic tribes. In the opinion of Randall R. Cloud, the permanent separation of the Greek East from the Latin West was ``the fundamental reason for the estrangement that soon followed between the Greek and the Latin Christians ''.
Document 10: Fall of the Western Roman Empire: Relevant dates include 117 CE, when the Empire was at its greatest territorial extent, and the accession of Diocletian in 284. Irreversible major territorial loss, however, began in 376 with a large - scale irruption of Goths and others. In 395, after winning two destructive civil wars, Theodosius I died, leaving a collapsing field army and the Empire, still plagued by Goths, divided between his two incapable sons. By 476 when Odoacer deposed the Emperor Romulus, the Western Roman Emperor wielded negligible military, political, or financial power and had no effective control over the scattered Western domains that could still be described as Roman. Invading barbarians had established their own power in most of the area of the Western Empire. While its legitimacy lasted for centuries longer and its cultural influence remains today, the Western Empire never had the strength to rise again.
Document 11: Ferraù Fenzoni: Ferraù Fenzoni was born in (Faenza) and arrived in Rome as a young man in the early 1580s. He was apprenticed in Rome during the papacy of Gregory XIII and worked on numerous fresco cycles under pope Sixtus V, such as the Loggia della Benedizioni in the Lateran Palace, the frescoes on the walls and vaults of the Scala Santa of the adjacent Basilica of San Giovanni in Laterano, and the decoration in the Sistine library.
Document 12: The Entombment (Michelangelo): According to documents discovered in 1981, Michelangelo had been commissioned to paint a panel for the church of Sant'Agostino in Rome, but in the end gave back the sum received. It is probable that this work was the "Entombment", which remained unfinished upon Michelangelo's return to Florence.
Document 13: Fiesole Altarpiece: The Fiesole Altarpiece is a painting by the Italian early Renaissance master Fra Angelico, executed around 1424–1425. It is housed in the Convent of San Domenico, Fiesole, central Italy. The background was repainted by Lorenzo di Credi in 1501.
Document 14: Southern Europe: The Roman Empire came to dominate the entire Mediterranean basin in a vast empire based on Roman law and Roman legions. It promoted trade, tolerance, and Greek culture. By 300 AD the Roman Empire was divided into the Western Roman Empire based in Rome, and the Eastern Roman Empire based in Constantinople. The attacks of the Germanic peoples of northern Europe led to the Fall of the Western Roman Empire in AD 476, a date which traditionally marks the end of the classical period and the start of the Middle Ages.
Document 15: The Last Judgment (Fra Angelico, Florence): The Last Judgment (tempera on panel) is a painting by the Renaissance artist Fra Angelico. It was commissioned by the Camaldolese Order for the newly elected abbot, the humanist scholar Ambrogio Traversari. It is variously dated to c1425, 1425–30 and 1431. It was originally sited in the church of Santa Maria degli Angeli and now is in the museum of San Marco, Florence. It is not to be confused with another Fra Angelico "Last Judgement" in the Gemäldegalerie, Berlin.
