Please answer the following question: Information:  - Ancient Rome was an Italic civilization that began on the Italian Peninsula as early as the 8th century BC. Located along the Mediterranean Sea and centered on the city of Rome, it expanded to become one of the largest empires in the ancient world with an estimated 50 to 90 million inhabitants (roughly 20% of the world's population) and covering 5.0 million square kilometers at its height in AD 117.  - Oliver Grau ( born 24 October 1965 ) is a German art historian and media theoretician with a focus on image science , modernity and media art as well as culture of the 19th century and Italian art of the Renaissance .  - Carolingian art comes from the Frankish Empire in the period of roughly 120 years from about 780 to 900  during the reign of Charlemagne and his immediate heirs  popularly known as the Carolingian Renaissance. The art was produced by and for the court circle and a group of important monasteries under Imperial patronage; survivals from outside this charmed circle show a considerable drop in quality of workmanship and sophistication of design. The art was produced in several centres in what are now France, Germany, Austria, northern Italy and the Low Countries, and received considerable influence, via continental mission centres, from the Insular art of the British Isles, as well as a number of Byzantine artists who appear to have been resident in Carolingian centres.  - Paestum was a major ancient Greek city on the coast of the Tyrrhenian Sea in Magna Graecia (southern Italy). The ruins of Paestum are famous for their three ancient Greek temples in the Doric order, dating from about 600 to 450 BC, which are in a very good state of preservation. The city walls and amphitheatre are largely intact, and the bottom of the walls of many other structures remain, as well as paved roads. The site is open to the public, and there is a modern national museum within it, which also contains the finds from the associated Greek site of Foce del Sele.  - Since prehistoric times, Greeks, Etruscans and Celts have inhabited the south, centre and north of the Italian peninsula respectively. The very numerous Rock Drawings in Valcamonica go back to 8,000 BC, and there are rich remains of Etruscan art from thousands of tombs, as well as rich remains from the Greek colonies at Paestum, Agrigento and elsewhere. Ancient Rome finally emerged as the dominant Italian and European power. The Roman remains in Italy are of extraordinary richness, from the grand Imperial monuments of Rome itself to the survival of exceptionally preserved ordinary buildings in Pompeii and neighbouring sites. Following the fall of the Roman Empire, in the Middle Ages Italy, especially the north, remained an important centre, not only of the Carolingian art and Ottonian art of the Holy Roman Emperors, but for the Byzantine art of Ravenna and other sites.  - Modernity is a term of art used in the humanities and social sciences to designate both a historical period (the modern era), as well as the ensemble of particular socio-cultural norms, attitudes and practices that arose in post-medieval Europe and have developed since, in various ways and at various times, around the world. While it includes a wide range of interrelated historical processes and cultural phenomena (from fashion to modern warfare), it can also refer to the subjective or existential experience of the conditions they produce, and their ongoing impact on human culture, institutions, and politics .  - Social science is a major category of academic disciplines, concerned with society and the relationships among individuals within a society. It in turn has many branches, each of which is considered a "social science". The main social sciences include economics, political science, human geography, demography, and sociology. In a wider sense, social science also includes some fields in the humanities such as anthropology, archaeology, jurisprudence, history, and linguistics. The term is also sometimes used to refer specifically to the field of sociology, the original 'science of society', established in the 19th century. A more detailed list of sub-disciplines within the social sciences can be found at Outline of social science.  - The Greeks or Hellenes are an ethnic group native to Greece, Cyprus, southern Albania, Turkey, Sicily, Egypt and, to a lesser extent, other countries surrounding the Mediterranean Sea. They also form a significant diaspora, with Greek communities established around the world.  - The Holy Roman Emperor (historically "" "Emperor of the Romans") was the ruler of the Holy Roman Empire. From an autocracy in Carolingian times the title evolved into an elected monarchy chosen by the Prince-electors. Until the Reformation the Emperor elect ("imperator electus") was required to be crowned by the Pope before assuming the imperial title.  - Rome is a city and special "comune" (named "Roma Capitale") in Italy. Rome is the capital of Italy and of the Lazio region. With 2,870,336 residents in , it is also the country's largest and most populated "comune" and fourth-most populous city in the European Union by population within city limits. The Metropolitan City of Rome has a population of 4.3 million residents. The city is located in the central-western portion of the Italian Peninsula, within Lazio (Latium), along the shores of Tiber river. The Vatican City is an independent country geographically located within the city boundaries of Rome, the only existing example of a country within a city: for this reason Rome has been often defined as capital of two states.   - Pompeii was an ancient Roman town-city near modern Naples, in the Campania region of Italy, in the territory of the comune of Pompei. Pompeii, along with Herculaneum and many villas in the surrounding area, was mostly destroyed and buried under of volcanic ash and pumice in the eruption of Mount Vesuvius in 79 AD.  - In the history of Europe, the Middle Ages or medieval period lasted from the 5th to the 15th century. It began with the fall of the Western Roman Empire and merged into the Renaissance and the Age of Discovery. The Middle Ages is the middle period of the three traditional divisions of Western history: classical antiquity, the medieval period, and the modern period. The medieval period is itself subdivided into the Early, High, and Late Middle Ages.  - Italy, officially the Italian Republic, is a unitary parliamentary republic in Europe. Located in the heart of the Mediterranean Sea, Italy shares open land borders with France, Switzerland, Austria, Slovenia, San Marino and Vatican City. Italy covers an area of and has a largely temperate seasonal climate and Mediterranean climate; due to its shape, it is often referred to in Italy as "lo Stivale" (the Boot). With 61 million inhabitants, it is the fourth most populous EU member state.  - The stone carvings of Val Camonica (Camonica Valley) are located in the Province of Brescia, Italy, and constitute the largest collections of prehistoric petroglyphs in the world. The collection was recognized by Unesco in 1979 and was Italy's first recognized World Heritage Site. Unesco has formally recognized more than 140,000 figures and symbols, but new discoveries have increased the number of catalogued incisions to between 200,000 and 300,000. The petroglyphs are spread on all surfaces of the valley, but concentrated in the areas of Darfo Boario Terme, Capo di Ponte, Nadro, Cimbergo and Paspardo.  - The Renaissance was a period in European history, from the 14th to the 17th century, regarded as the cultural bridge between the Middle Ages and modern history. It started as a cultural movement in Italy in the Late Medieval period and later spread to the rest of Europe, marking the beginning of the Early Modern Age.  - Ravenna (also locally ) is the capital city of the Province of Ravenna, in the Emilia-Romagna region of Northern Italy. It was the capital city of the Western Roman Empire from 402 until that empire collapsed in 476. It then served as the capital of the Kingdom of the Ostrogoths until it was re-conquered in 540 by the Eastern Roman (Byzantine) Empire. Afterwards, the city formed the centre of the Byzantine Exarchate of Ravenna until the invasion of the Lombards in 751, after which it became the seat of the Kingdom of the Lombards.  - Etruscan art was produced by the Etruscan civilization in central Italy between the 9th and 2nd centuries BC. From around 600 BC it was heavily influenced by Greek art, which was imported by the Etruscans, but always retained distinct characteristics. Particularly strong in this tradition were figurative sculpture in terracotta (especially life-size on sarcophagi or temples), wall-painting and metalworking especially in bronze. Jewellery and engraved gems of high quality were produced.   - Ottonian art is a style in pre-romanesque German art, covering also some works from the Low Countries, northern Italy and eastern France. It was named by the art historian Hubert Janitschek after the Ottonian dynasty which ruled Germany and northern Italy between 919 and 1024 under the kings Henry I, Otto I, Otto II, Otto III and Henry II. With Ottonian architecture, it is a key component of the Ottonian Renaissance (circa 9511024). However, the style neither began nor ended to neatly coincide with the rule of the dynasty. It emerged some decades into their rule and persisted past the Ottonian emperors into the reigns of the early Salian dynasty, which lacks an artistic "style label" of its own. In the traditional scheme of art history, Ottonian art follows Carolingian art and precedes Romanesque art, though the transitions at both ends of the period are gradual rather than sudden. Like the former and unlike the latter, it was very largely a style restricted to a few of the small cities of the period, and important monasteries, as well as the court circles of the emperor and his leading vassals.  - The Celts (occasionally , see pronunciation of "Celtic") were people in Iron Age and Medieval Europe who spoke Celtic languages and had cultural similarities, although the relationship between ethnic, linguistic and cultural factors in the Celtic world remains uncertain and controversial. The exact geographic spread of the ancient Celts is also disputed; in particular, the ways in which the Iron Age inhabitants of Great Britain and Ireland should be regarded as Celts has become a subject of controversy.
