Question: What was the Pantheon used for, in the city that was central to imperial life in the early fifth century, for the empire that the term 'The West' comes from?

full_context: Document 1: 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 2: Middle Ages: Roman city life and culture changed greatly in the early Middle Ages. Although Italian cities remained inhabited, they contracted significantly in size. Rome, for instance, shrank from a population of hundreds of thousands to around 30,000 by the end of the 6th century. Roman temples were converted into Christian churches and city walls remained in use. In Northern Europe, cities also shrank, while civic monuments and other public buildings were raided for building materials. The establishment of new kingdoms often meant some growth for the towns chosen as capitals. Although there had been Jewish communities in many Roman cities, the Jews suffered periods of persecution after the conversion of the empire to Christianity. Officially they were tolerated, if subject to conversion efforts, and at times were even encouraged to settle in new areas.
Document 3: Middle Ages: The invasions brought new ethnic groups to Europe, although some regions received a larger influx of new peoples than others. In Gaul for instance, the invaders settled much more extensively in the north-east than in the south-west. Slavic peoples settled in Central and Eastern Europe and the Balkan Peninsula. The settlement of peoples was accompanied by changes in languages. The Latin of the Western Roman Empire was gradually replaced by languages based on, but distinct from, Latin, collectively known as Romance languages. These changes from Latin to the new languages took many centuries. Greek remained the language of the Byzantine Empire, but the migrations of the Slavs added Slavonic languages to Eastern Europe.
Document 4: Parthenon: The Parthenon (/ ˈpɑːrθəˌnɒn, - nən /; Ancient Greek: Παρθενών; Greek: Παρθενώνας, Parthenónas) is a former temple, on the Athenian Acropolis, Greece, dedicated to the goddess Athena, whom the people of Athens considered their patron. Construction began in 447 BC when the Athenian Empire was at the peak of its power. It was completed in 438 BC although decoration of the building continued until 432 BC. It is the most important surviving building of Classical Greece, generally considered the zenith of the Doric order. Its decorative sculptures are considered some of the high points of Greek art. The Parthenon is regarded as an enduring symbol of Ancient Greece, Athenian democracy and Western civilization, and one of the world's greatest cultural monuments. To the Athenians who built it, the Parthenon and other Periclean monuments of the Acropolis, were seen fundamentally as a celebration of Hellenic victory over the Persian invaders and as a thanksgiving to the gods for that victory. The Greek Ministry of Culture is currently carrying out a programme of selective restoration and reconstruction to ensure the stability of the partially ruined structure.
Document 5: Rome: Rome's history spans 28 centuries. While Roman mythology dates the founding of Rome at around 753 BC, the site has been inhabited for much longer, making it one of the oldest continuously occupied sites in Europe. The city's early population originated from a mix of Latins, Etruscans, and Sabines. Eventually, the city successively became the capital of the Roman Kingdom, the Roman Republic and the Roman Empire, and is regarded by some as the first ever metropolis. It was first called "The Eternal City" (; ) by the Roman poet Tibullus in the 1st century BC, and the expression was also taken up by Ovid, Virgil, and Livy. Rome is also called the "Caput Mundi" (Capital of the World). After the fall of the Western Empire, which marked the beginning of the Middle Ages, Rome slowly fell under the political control of the Papacy, and in the 8th century it became the capital of the Papal States, which lasted until 1870. Beginning with the Renaissance, almost all the popes since Nicholas V (1447–1455) pursued over four hundred years a coherent architectural and urban programme aimed at making the city the artistic and cultural centre of the world. In this way, Rome became first one of the major centres of the Italian Renaissance, and then the birthplace of both the Baroque style and Neoclassicism. Famous artists, painters, sculptors and architects made Rome the centre of their activity, creating masterpieces throughout the city. In 1871, Rome became the capital of the Kingdom of Italy, which, in 1946, became the Italian Republic.
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: Pantheon, Rome: The Pantheon (/ ˈpænθiən / or US: / ˈpænθiɒn /; Latin: Pantheum, from Greek Πάνθειον Pantheion, ``(temple) of all the gods '') is a former Roman temple, now a church, in Rome, Italy, on the site of an earlier temple commissioned by Marcus Agrippa during the reign of Augustus (27 BC -- 14 AD). The present building was completed by the emperor Hadrian and probably dedicated about 126 AD. He retained Agrippa's original inscription, which has caused confusion over its date of construction as the original Pantheon burned down, so it is not certain when the present one was built.
Document 8: Roman Empire: The Roman Empire (Latin: Imperium Rōmānum, Classical Latin: (ɪmˈpɛ. ri. ũː roːˈmaː. nũː); Koine and Medieval Greek: Βασιλεία τῶν Ῥωμαίων, tr. Basileia tōn Rhōmaiōn) was the post-Roman Republic period of the ancient Roman civilization, with a government headed by emperors and large territorial holdings around the Mediterranean Sea in Europe, Africa and Asia. The city of Rome was the largest city in the world c. 100 BC -- c. AD 400, with Constantinople (New Rome) becoming the largest around AD 500, and the Empire's population grew to an estimated 50 to 90 million inhabitants (roughly 20% of the world's population at the time). The 500 - year - old republic which preceded it had been severely destabilized in a series of civil wars and political conflict, during which Julius Caesar was appointed as perpetual dictator and then assassinated in 44 BC. Civil wars and executions continued, culminating in the victory of Octavian, Caesar's adopted son, over Mark Antony and Cleopatra at the Battle of Actium in 31 BC and the annexation of Egypt. Octavian's power was then unassailable and in 27 BC the Roman Senate formally granted him overarching power and the new title Augustus, effectively marking the end of the Roman Republic.
Document 9: Middle Ages: The High Middle Ages was a period of tremendous expansion of population. The estimated population of Europe grew from 35 to 80 million between 1000 and 1347, although the exact causes remain unclear: improved agricultural techniques, the decline of slaveholding, a more clement climate and the lack of invasion have all been suggested. As much as 90 per cent of the European population remained rural peasants. Many were no longer settled in isolated farms but had gathered into small communities, usually known as manors or villages. These peasants were often subject to noble overlords and owed them rents and other services, in a system known as manorialism. There remained a few free peasants throughout this period and beyond, with more of them in the regions of Southern Europe than in the north. The practice of assarting, or bringing new lands into production by offering incentives to the peasants who settled them, also contributed to the expansion of population.
Document 10: Santa Caterina dei Funari: The church is located where the Castro Aureo of the Circus Flaminius was located, built by Gaius Flaminius in 221 B.C. Prior to the 13th century, the seats of the surrounding semi-ruined amphitheater were used to dry the wares produced by the string- and rope-makers ("funari"), hence, the name of the church. Originally a small church dedicated to Santa Rosa di Viterbo was adjacent. The original church was a three-naved basilica, called "Santa Maria de Donna Rosa in Castro Aureo", named for the first time in 1192 in a document of Pope Celestine III. It was rebuilt in the 9th century with a single nave and dedicated to St Catherine of Alexandria and later also called Santa Caterina dei Funari.
Document 11: Early Middle Ages: For almost a thousand years, Rome was the most politically important, richest and largest city in Europe. Around 100 CE, it had a population of about 450,000, and declined to a mere 20,000 during the Early Middle Ages, reducing the sprawling city to groups of inhabited buildings interspersed among large areas of ruins and vegetation.
Document 12: 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 13: Parthenon: The Parthenon itself replaced an older temple of Athena, which historians call the Pre-Parthenon or Older Parthenon, that was destroyed in the Persian invasion of 480 BC. The temple is archaeoastronomically aligned to the Hyades. Like most Greek temples, the Parthenon served a practical purpose as the city treasury. For a time, it served as the treasury of the Delian League, which later became the Athenian Empire. In the final decade of the sixth century AD, the Parthenon was converted into a Christian church dedicated to the Virgin Mary.
Document 14: Middle Ages: Christianity was a major unifying factor between Eastern and Western Europe before the Arab conquests, but the conquest of North Africa sundered maritime connections between those areas. Increasingly the Byzantine Church differed in language, practices, and liturgy from the western Church. The eastern church used Greek instead of the western Latin. Theological and political differences emerged, and by the early and middle 8th century issues such as iconoclasm, clerical marriage, and state control of the church had widened to the extent that the cultural and religious differences were greater than the similarities. The formal break came in 1054, when the papacy and the patriarchy of Constantinople clashed over papal supremacy and excommunicated each other, which led to the division of Christianity into two churches—the western branch became the Roman Catholic Church and the eastern branch the Orthodox Church.
Document 15: Pantheon, Rome: It is one of the best - preserved of all Ancient Roman buildings, in large part because it has been in continuous use throughout its history, and since the 7th century, the Pantheon has been used as a church dedicated to ``St. Mary and the Martyrs ''(Latin: Santa Maria ad Martyres) but informally known as`` Santa Maria Rotonda''. The square in front of the Pantheon is called Piazza della Rotonda. The Pantheon is a state property, ruled by Italy's Ministry of Cultural Heritage and Activities and Tourism through the Polo Museale del Lazio; in 2013 it was visited by over 6 million people.
