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

<P0-S0> vladimir's choice of eastern christianity may also have reflected his close personal ties with constantinople, which dominated the black sea and hence trade on kiev's most vital commercial route, the dnieper river. <P0-S1> adherence to the eastern church had long-range political, cultural, and religious consequences. <P0-S2> the church had a liturgy written in cyrillic and a corpus of translations from greek that had been produced for the slavic peoples. <P0-S3> this literature facilitated the conversion to christianity of the eastern slavs and introduced them to rudimentary greek philosophy, science, and historiography without the necessity of learning greek (there were some merchants who did business with greeks and likely had an understanding of contemporary business greek). <P0-S4> in contrast, educated people in medieval western and central europe learned latin. <P0-S5> enjoying independence from the roman authority and free from tenets of latin learning, the east slavs developed their own literature and fine arts, quite distinct from those of other eastern orthodox countries. <P0-S6> [citation needed] (see old east slavic language and architecture of kievan rus for details ). <P0-S7> following the great schism of 1054, the rus' church maintained communion with both rome and constantinople for some time, but along with most of the eastern churches it eventually split to follow the eastern orthodox. <P0-S8> that being said, unlike other parts of the greek world, kievan rus' did not have a strong hostility to the western world. <SEP> <P1-S0> sealing the tomb is a great altarpiece triptych by william hogarth in the english city of bristol. <P1-S1> it was commissioned for st mary redcliffe in 1755. in the 19th century attempts were made to sell it, but it was given to the bristol fine art academy, which became the royal west of england academy. <P1-S2> its size made it difficult to display and it was rolled up and stored in the basement. <P1-S3> in 1973 it was displayed in the ecclesiastical museum created in the war-damaged church of st nicholas. <P1-S4> when the museum closed it was converted to offices; however the triptych remains in the building. <P1-S5> it will be on display to the public again when the church is re-consecrated in 2018. <SEP> <P2-S0> 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. <P2-S1> 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. <P2-S2> The story seems possible and even likely. <P2-S3> 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. <P2-S4> Moreover, the archbishop in 1446–1459 was the Dominican Antoninus of Florence (Antonio Pierozzi), canonized by Pope Adrian VI in 1523. <P2-S5> In 1447 Fra Angelico was in Orvieto with his pupil, Benozzo Gozzoli, executing works for the Cathedral. <P2-S6> Among his other pupils were Zanobi Strozzi. <SEP> <P3-S0> 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. <P3-S1> However, he had little power in the West, which was ruled almost entirely by various Germanic tribes. <P3-S2> 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 ''. <SEP> <P4-S0> 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.
