Context: 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. , Aulus Gellius (c. 125  after 180 AD) was a Latin author and grammarian, who was probably born and certainly brought up in Rome. He was educated in Athens, after which he returned to Rome, where he held a judicial office. He is famous for his "Attic Nights", a commonplace book, or compilation of notes on grammar, philosophy, history, antiquarianism, and other subjects, preserving fragments of many authors and works who otherwise might be unknown today., Athens ("Athína" ) is the capital and largest city of Greece. Athens dominates the Attica region and is one of the world's oldest cities, with its recorded history spanning over 3,400 years, and its earliest human presence starting somewhere between the 11th and 7th millennia BC. Classical Athens was a powerful city-state that emerged in conjunction with the seagoing development of the port of Piraeus, which had been a distinct city prior to its 5th century BC incorporation with Athens. A centre for the arts, learning and philosophy, home of Plato's Academy and Aristotle's Lyceum, it is widely referred to as the cradle of Western civilization and the birthplace of democracy, largely because of its cultural and political impact on the European continent, and in particular the Romans. In modern times, Athens is a large cosmopolitan metropolis and central to economic, financial, industrial, maritime, political and cultural life in Greece. In 2015, Athens was ranked the world's 29th richest city by purchasing power and the 67th most expensive in a UBS study., Hadrian (24 January 76  10 July 138) was Roman emperor from 117 to 138. Hadrian is known for building Hadrian's Wall, which marked the northern limit of Britannia. He also rebuilt the Pantheon and constructed the Temple of Venus and Roma. Philhellene in most of his tastes, he is considered by some to have been a humanist, and he is regarded as the third of the Five Good Emperors., Hadrian's Wall, also called the Roman Wall, Picts' Wall, or "Vallum Hadriani" in Latin, was a defensive fortification in the Roman province of Britannia, begun in 122 AD in the reign of the emperor Hadrian. It ran from the banks of the River Tyne near the North Sea to the Solway Firth on the Irish Sea, and was the northern limit of the Roman Empire, immediately north of which were the lands of the northern Ancient Britons, including the Picts., Quintus Terentius Scaurus , Latin grammarian , flourished during the reign of Hadrian ( Aulus Gellius xi.15 ) . He was the author of an ars grammatica and commentaries on Horace , Virgil 's Aeneid and perhaps Plautus . Under his name , two fragments are extant -- the longer from his work on orthography ( De orthographia ) , the shorter ( chiefly on the use of prepositions ) from another grammatical work . They have both been published by Heinrich Keil in Scriptores de orthographia , the 7th volume of his Grammatici Latini ( Teubner , 1880 ) ; the De orthographia has appeared in a new edition prepared by Federico Biddau ( Weidmann , 2008 ) ., The Roman emperor was the ruler of the Roman Empire during the imperial period (starting in 27 BC). The emperors used a variety of different titles throughout history. Often when a given Roman is described as becoming "emperor" in English, it reflects his taking of the title "Augustus" or "Caesar". Another title often used was "imperator", originally a military honorific. Early Emperors also used the title "princeps" (first citizen). Emperors frequently amassed republican titles, notably "Princeps Senatus", "Consul" and "Pontifex Maximus"., The Temple of Venus and Roma Latin: Templum Veneris et Romae is thought to have been the largest temple in Ancient Rome. Located on the Velian Hill, between the eastern edge of the "Forum Romanum" and the Colosseum, it was dedicated to the goddesses "Venus Felix" ("Venus the Bringer of Good Fortune") and "Roma Aeterna" ("Eternal Rome"). The architect was the emperor Hadrian and construction began in 121. It was officially inaugurated by Hadrian in 135, and finished in 141 under Antoninus Pius. Damaged by fire in 307, it was restored with alterations by the emperor Maxentius., Subject: quintus terentius scaurus, Relation: country_of_citizenship, Options: (A) ancient rome (B) athens (C) greece (D) italy (E) roman empire (F) vatican city
