Question: When did the city where the creator of Annunciation of Cortona died begin following a monotheistic religion?

full_context: Document 1: Religion in ancient Rome: The Western emperor Gratian refused the office of pontifex maximus, and against the protests of the senate, removed the altar of Victory from the senate house and began the disestablishment of the Vestals. Theodosius I briefly re-united the Empire: in 391 he officially adopted Nicene Christianity as the Imperial religion and ended official support for all other creeds and cults. He not only refused to restore Victory to the senate-house, but extinguished the Sacred fire of the Vestals and vacated their temple: the senatorial protest was expressed in a letter by Quintus Aurelius Symmachus to the Western and Eastern emperors. Ambrose, the influential Bishop of Milan and future saint, wrote urging the rejection of Symmachus's request for tolerance. Yet Theodosius accepted comparison with Hercules and Jupiter as a living divinity in the panegyric of Pacatus, and despite his active dismantling of Rome's traditional cults and priesthoods could commend his heirs to its overwhelmingly Hellenic senate in traditional Hellenic terms.[clarification needed] He was the last emperor of both East and West.
Document 2: Religion in ancient Rome: After the Great Fire of Rome in 64 AD, Emperor Nero accused the Christians as convenient scapegoats, who were later persecuted and killed. From that point on, Roman official policy towards Christianity tended towards persecution. During the various Imperial crises of the 3rd century, “contemporaries were predisposed to decode any crisis in religious terms”, regardless of their allegiance to particular practices or belief systems. Christianity drew its traditional base of support from the powerless, who seemed to have no religious stake in the well-being of the Roman State, and therefore threatened its existence. The majority of Rome’s elite continued to observe various forms of inclusive Hellenistic monism; Neoplatonism in particular accommodated the miraculous and the ascetic within a traditional Graeco-Roman cultic framework. Christians saw these ungodly practices as a primary cause of economic and political crisis.
Document 3: 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.
Document 4: 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 5: Cortona Triptych: The Cortona Triptych is a Catholic Church depiction of the Madonna and Child with saints, painted by Fra Angelico. It is now kept at the Diocesan Museum in Cortona, Italy. The painting dates from 1436-1437.
Document 6: 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 7: Constantine the Great and Christianity: During the reign of the Roman Emperor Constantine the Great (306 -- 337 AD), Christianity began to transition to the dominant religion of the Roman Empire. Historians remain uncertain about Constantine's reasons for favoring Christianity, and theologians and historians have often argued about which form of Early Christianity he subscribed to. There is no consensus among scholars as to whether he adopted his mother Helena's Christianity in his youth, or, as claimed by Eusebius, encouraged her to convert to the faith himself. Some scholars question the extent to which he should be considered a Christian emperor: ``Constantine saw himself as an 'emperor of the Christian people'. If this made him a Christian is the subject of... debate, ''although he allegedly received a baptism shortly before his death.
Document 8: Religion in ancient Rome: In 380, under Theodosius I, Nicene Christianity became the official state religion of the Roman Empire. Christian heretics as well as non-Christians were subject to exclusion from public life or persecution, though Rome's original religious hierarchy and many aspects of its ritual influenced Christian forms, and many pre-Christian beliefs and practices survived in Christian festivals and local traditions.
Document 9: 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 10: Annunciation (Caravaggio): The Annunciation is an oil painting by the Italian master Michelangelo Merisi da Caravaggio, finished around 1608. It housed in the Musée des Beaux-Arts de Nancy.
Document 11: The Annunciation, with Saint Emidius: The Annunciation, with Saint Emidius is an altarpiece by Italian artist Carlo Crivelli showing an artistic adaptation of the Annunciation. The altarpiece was painted for the Church of SS. Annunziata in the Italian town of Ascoli Piceno, in the region of Marche, to celebrate the self-government granted to the town in 1482 by Pope Sixtus IV. The painting was removed to the Pinacoteca di Brera in Milan in 1811, but passed to Auguste-Louis de Sivry in 1820, and had reached England by the mid-19th century. It has been housed in the National Gallery in London since it was donated by Henry Labouchere, 1st Baron Taunton in 1864.
Document 12: Annunciation of Cortona: The Annunciation of Cortona is a panel-painting altarpiece or retable by Fra Angelico: once housed in the Church of Gesù of Cortona, it is now held at the Museo Diocesano in Cortona.
Document 13: State church of the Roman Empire: Nicene Christianity became the state church of the Roman Empire with the Edict of Thessalonica in 380 AD, when Emperor Theodosius I made it the Empire's sole authorized religion. The Eastern Orthodox Church, Oriental Orthodoxy, and the Catholic Church each claim to be the historical continuation of this church in its original form, but do not identify with it in the caesaropapist form that it took later. Unlike Constantine I, who with the Edict of Milan of 313 AD had established tolerance for Christianity without placing it above other religions and whose involvement in matters of the Christian faith extended to convoking councils of bishops who were to determine doctrine and to presiding at their meetings, but not to determining doctrine himself, Theodosius established a single Christian doctrine (specified as that professed by Pope Damasus I of Rome and Pope Peter II of Alexandria) as the Empire's official religion.
Document 14: Annunciation (van Eyck, Washington): The Annunciation is an oil painting by the Early Netherlandish master Jan van Eyck, from around 1434–1436. The panel is housed in the National Gallery of Art, in Washington D.C. It was originally on panel but has been transferred to canvas. It is thought that it was the left (inner) wing of a triptych; there has been no sighting of the other wings since before 1817. The annunciation is a highly complex work, whose iconography is still debated by art historians.
Document 15: 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.
