Hadrian in the context of "Orestias"

The founding of Rome was a prehistoric event or process later greatly embellished by Roman historians and poets. Archaeological evidence indicates that Rome developed from the gradual union of several hilltop villages during the Final Bronze Age or early Iron Age. Prehistoric habitation of the Italian Peninsula occurred by 48,000 years ago, with the area of Rome being settled by around 1600 BC. Some evidence on the Capitoline Hill possibly dates as early as c. 1700 BC and the nearby valley that later housed the Roman Forum had a developed necropolis by at least 1000 BC. The combination of the hilltop settlements into a single polity by the later 8th century BC was probably influenced by the trend for city-state formation emerging from ancient Greece.

Roman myth held that their city was founded by Romulus, son of the war god Mars and the Vestal virgin Rhea Silvia, fallen princess of Alba Longa and descendant of Aeneas of Troy. Exposed on the Tiber river, Romulus and his twin Remus were suckled by a she-wolf at the Lupercal before being raised by the shepherd Faustulus, taking revenge on their usurping great-uncle Amulius, and restoring Alba Longa to their grandfather Numitor. The brothers then decided to establish a new town but quarrelled over some details, ending with Remus's murder and the establishment of Rome on the Palatine Hill. The year of the supposed founding was variously computed by ancient historians, but the two dates seeming to be officially sanctioned were the Varronian chronology's 753 BC (used by Claudius's Secular Games and Hadrian's Romaea) and the adjacent year of 752 BC (used by the Fasti and the Secular Games of Antoninus Pius and Philip I). Despite known errors in Varro's calculations, it is the 753 BC date that continues to form the basis for most modern calculations of the AUC calendar era.

The Roman provinces (Latin: provincia, pl. provinciae) were the administrative regions of Ancient Rome outside Roman Italy that were controlled by the Romans under the Roman Republic and later the Roman Empire. Each province was ruled by a Roman appointed as governor.

For centuries, it was the largest administrative unit of the foreign possessions of ancient Rome. With the administrative reform initiated by Diocletian, it became a third level administrative subdivision of the Roman Empire, or rather a subdivision of the imperial dioceses (in turn subdivisions of the imperial prefectures).

The Greco-Roman world /ˌɡriːkoʊˈroʊmən, ˌɡrɛkoʊ-/, also Greco-Roman civilization, Greco-Roman culture or Greco-Latin culture (spelled Græco-Roman or Graeco-Roman in British English), as understood by modern scholars and writers, includes the geographical regions and countries that culturally—and so historically—were directly and intimately influenced by the language, culture, government and religion of the Ancient Greeks and Romans. A better-known term is classical antiquity. In exact terms the area refers to the "Mediterranean world", the extensive tracts of land centered on the Mediterranean and Black Sea basins, the "swimming pool and spa" of the Greeks and the Romans, in which those peoples' cultural perceptions, ideas, and sensitivities became dominant in classical antiquity.

That process was aided by the universal adoption of Greek as the language of intellectual culture and commerce in the Eastern Mediterranean and of Latin as the language of public administration and of forensic advocacy, especially in the Western Mediterranean.

Marcus Aurelius Antoninus (/ɔːˈriːliəs/ or-EE-lee-əs, Latin: [ˈmaːrkʊs au̯ˈreːli.us antoːˈniːnʊs]; 26 April 121 – 17 March 180) was Roman emperor from 161 to 180 and a Stoic philosopher. He was a member of the Nerva–Antonine dynasty, the last of the rulers later known as the Five Good Emperors and the last emperor of the Pax Romana, an age of relative peace, calm, and stability for the Roman Empire lasting from 27 BC to 180 AD. He served as Roman consul in 140, 145, and 161.

Marcus Aurelius was the son of the praetor Marcus Annius Verus and his wife, Domitia Calvilla. He was related through marriage to the emperors Trajan and Hadrian. Marcus was three when his father died, and was raised by his mother and paternal grandfather. After Hadrian's adoptive son, Aelius Caesar, died in 138, Hadrian adopted Marcus's uncle Antoninus Pius as his new heir. In turn, Antoninus adopted Marcus and Lucius, the son of Aelius. Hadrian died that year, and Antoninus became emperor. Now heir to the throne, Marcus studied Greek and Latin under tutors such as Herodes Atticus and Marcus Cornelius Fronto. He married Antoninus's daughter Faustina in 145.

Titus Aelius Hadrianus Antoninus Pius (/ˌæntəˈnaɪnəs ˈpaɪəs/; Latin: [antoːˈniːnus ˈpius]; 19 September 86 – 7 March 161) was Roman emperor from AD 138 to 161. He was the fourth of the Five Good Emperors from the Nerva–Antonine dynasty.

Born into a senatorial family, Antoninus held various offices during the reign of Emperor Hadrian. He married Hadrian's niece Faustina, and Hadrian adopted him as his son and successor shortly before his death. Antoninus acquired the cognomen Pius after his accession to the throne, either because he compelled the Senate to deify his adoptive father, or because he had saved senators sentenced to death by Hadrian in his later years. His reign is notable for the peaceful state of the Empire, with no major revolts or military incursions during this time. A successful military campaign in southern Scotland early in his reign resulted in the construction of the Antonine Wall.

The Raeti (/ˈraɪtiː/ RY-tee; spelling variants: Rhaeti, Rheti or Rhaetii) were a confederation of Alpine tribes, whose language and culture were related to those of the Etruscans. Before the Roman conquest, they inhabited present-day Tyrol in Austria, eastern Switzerland and the Alpine regions of northeastern Italy. After the Roman conquest, the province of Raetia was formed, which included parts of present-day Germany south of the Danube.

The etymology of the name Raeti is uncertain. The Roman province of Raetia was named after these people.

Hadrian's Gate (Turkish: Üçkapılar, meaning "The Three Gates") is a memorial gate located in Antalya, Turkey, which was built in the name of the Roman emperor Hadrian, who visited the city in 130 CE. It was later incorporated in the walls that surround the city and harbor, of which it is the only remaining entrance gate today.

The gate was rediscovered by the Irish hydrographer Francis Beaufort in 1817, while commanding on HMS Fridericksteen.

The Colossus of Rhodes (Ancient Greek: ὁ Κολοσσὸς Ῥόδιος, romanized: ho Kolossòs Rhódios; Modern Greek: Κολοσσός της Ρόδου, romanized: Kolossós tis Ródou) was a statue of the Greek sun god Helios, erected in the city of Rhodes, on the Greek island of the same name, by Chares of Lindos in 280 BC. One of the Seven Wonders of the Ancient World, it was constructed to celebrate the successful defence of Rhodes against an attack by Demetrius I of Macedon, who had besieged it for a year with a large army and navy.

According to most contemporary descriptions, the Colossus stood approximately 70 cubits, or 33 metres (108 feet) high – approximately two-thirds of the height of the modern Statue of Liberty from feet to crown – making it the tallest statue in the ancient world. It collapsed during the earthquake of 226 BC, although parts of it were preserved. In accordance with the Oracle of Delphi, the Rhodians did not rebuild it. John Malalas wrote that Hadrian in his reign re-erected the Colossus, but he was mistaken. According to the Suda, the Rhodians were called Colossaeans (Κολοσσαεῖς), because they erected the statue on the island.

The Library of Celsus (Greek: Βιβλιοθήκη του Κέλσου) is an ancient Roman building in Ephesus, Anatolia, located near the modern town of Selçuk, in the İzmir Province of western Turkey. The building was commissioned in the years 110s CE by a consul of the Roman Empire, Tiberius Julius Aquila Polemaeanus, as a funerary monument for his father Tiberius Julius Celsus Polemaeanus, former proconsul of Asia, and completed during the reign of the Roman Emperor Hadrian, sometime after Aquila's death.

The Library of Celsus is considered an architectural marvel, and is one of the few remaining examples of great libraries of the ancient world located in the Roman Empire. It was the third-largest library in the Greco-Roman world behind only those of Alexandria and Pergamum, and is believed to have held around 12,000 scrolls. Celsus is buried in a crypt beneath the library in a decorated marble sarcophagus. The interior measured roughly 180 square metres (2,000 square feet).

The Temple of Olympian Zeus (Ancient Greek: Ναὸς τοῦ Ὀλυμπίου Διός, Naós tou Olympíou Diós), also known as the Olympieion or Columns of the Olympian Zeus, is a colossal temple in the centre of Athens, now in ruins. It was dedicated to "Olympian" Zeus, a name originating from his position as head of the Olympian gods. Construction began in the 6th century BC during the rule of the Athenian tyrants, who envisioned building the greatest temple in the ancient world, but it was not completed until the reign of Roman Emperor Hadrian in the 2nd century AD, some 638 years after the project had begun. During the Roman period, the temple, which included 104 colossal columns, was renowned as the largest temple in Greece and housed one of the largest cult statues in the ancient world.

The temple's glory was short-lived, as it fell into disuse after being pillaged during a Germanic invasion in 267 AD, just about a century after its completion. It was probably never repaired, and was reduced to ruins thereafter. In the centuries after the fall of the Roman Empire, it was extensively quarried for building materials to supply building projects elsewhere in the city. Today, a substantial part of the temple remains intact, notably 16 of the original gigantic columns, and it is now the center of a historical precinct.

The Roman legion (Latin: legiō, Latin: [ˈɫɛɡioː]) was the largest military unit of the Roman army, composed of Roman citizens serving as legionaries. During the Roman Republic the manipular legion comprised 4,200 infantry and 300 cavalry. In late Republican times the legions were formed of 5,200 men and were restructured around 10 cohorts, the first cohort being double strength. This structure persisted throughout the Principate and middle Empire, before further changes in the fourth century resulted in new formations of around 1,000 men.

In ancient Roman religion, Roma was a female deity who personified the city of Rome and, more broadly, the Roman state. She was created and promoted to represent and propagate certain of Rome's ideas about itself, and to justify its rule. She was portrayed on coins, sculptures, architectural designs, and at official games and festivals. Images of Roma had elements in common with other goddesses, such as Rome's Minerva, her Greek equivalent Athena and various manifestations of Greek Tyche, who protected Greek city-states; among these, Roma stands dominant, over piled weapons that represent her conquests, and promising protection to the obedient. Her "Amazonian" iconography shows her "manly virtue" (virtus) as fierce mother of a warrior race, augmenting rather than replacing local goddesses. On some coinage of the Roman Imperial era, she is shown as a serene advisor, partner and protector of ruling emperors. In Rome, the Emperor Hadrian built and dedicated a gigantic temple to her as Roma Aeterna ("Eternal Rome"), and to Venus Felix ("Venus the Bringer of Good Fortune"), emphasising the sacred, universal and eternal nature of the empire.

Roma's official cult served to advance the propagandist message of Imperial Rome. In Roman art and coinage, she is usually depicted in military form, with helmet and weapons. In Rome's eastern provinces, she was often shown with mural crown or cornucopia, or both. Her image is rarely found in a commonplace or domestic context. Roma was probably favoured by Rome's high-status Imperial representatives abroad, rather than the Roman populace at large. She was depicted on silver cups, arches, and sculptures, including the base of the column of Antoninus Pius. She survived into the Christian period as a personification of the Roman state. Her depiction seated with a shield and spear later influenced that of Britannia, personification of Britain.

The Pantheon (UK: /ˈpænθiən/, US: /-ɒn/; Latin: Pantheum, from Ancient Greek Πάνθειον (Pantheion) '[temple] of all the gods') is an ancient 2nd century Roman temple and, since AD 609, a Catholic church called the Basilica of St. Mary and the Martyrs (Italian: Basilica Santa Maria ad Martyres) in Rome, Italy. It is perhaps the most famous, and architecturally most influential, rotunda.

The Pantheon was built on the site of an earlier temple, which had been commissioned by Marcus Vipsanius Agrippa during the reign of Augustus (27 BC–AD 14). After the original burnt down, the present building was ordered by the emperor Hadrian and probably dedicated c. AD 126. Its date of construction is uncertain, because Hadrian chose to re-inscribe the new temple with Agrippa's original date inscription from the older temple.
