Ancient Rome

Archaeological evidence of settlement around Rome starts to emerge c. 1000 BC. Large-scale organisation appears only c. 800 BC, with the first graves in the Esquiline Hill's necropolis, along with a clay and timber wall on the bottom of the Palatine Hill dating to the middle of the 8th century BC. Starting from c. 650 BC, the Romans started to drain the valley between the Capitoline and Palatine Hills, where today sits the Roman Forum. By the 6th century BC, the Romans were constructing the Temple of Jupiter Optimus Maximus on the Capitoline and expanding to the Forum Boarium located between the Capitoline and Aventine Hills.

The Romans themselves had a founding myth, attributing their city to Romulus and Remus, offspring of Mars and a princess of the mythical city of Alba Longa. The sons, sentenced to death, were rescued by a wolf and returned to restore the Alban king and found a city. After a dispute, Romulus killed Remus and became the city's sole founder. The area of his initial settlement on the Palatine Hill was later known as Roma quadrata ('Square Rome'). The story dates at least to the 3rd century BC, and the later Roman antiquarian Marcus Terentius Varro placed the city's foundation to 753 BC. Another legend, recorded by Greek historian Dionysius of Halicarnassus, says that Prince Aeneas led a group of Trojans on a sea voyage to found a new Troy after the Trojan War. They landed on the banks of the Tiber River and a woman travelling with them, Roma, torched their ships to prevent them from leaving again. They named the settlement after her. The Roman poet Virgil recounted this legend in his classical epic poem the Aeneid.

Literary and archaeological evidence is clear on there having been kings in Rome, attested in fragmentary 6th-century BC texts. Long after the abolition of the Roman monarchy, a vestigial rex sacrorum was retained to exercise the monarch's former priestly functions. The Romans believed that their monarchy was elective, with seven legendary kings who were largely unrelated by blood.

Evidence of Roman expansion is clear in the 6th century BC; by its end, Rome controlled a territory of some 780 square kilometres (300 square miles) with a population perhaps as high as 35,000. A palace, the Regia, was constructed c. 625 BC; the Romans attributed the creation of their first popular organisations and the Senate to the regal period as well. Rome also started to extend its control over its Latin neighbours. While later Roman stories like the Aeneid asserted that all Latins descended from the character Aeneas, a common culture is attested to archaeologically. Attested to reciprocal rights of marriage and citizenship between Latin cities—the Jus Latii—along with shared religious festivals, further indicate a shared culture. By the end of the 6th century, most of this area had become dominated by the Romans.

By the end of the 6th century BC, Rome and many of its Italian neighbours entered a period of turbulence. Archaeological evidence implies some degree of large-scale warfare. According to tradition and later writers such as Livy, the Roman Republic was established c. 509 BC, when the last of the seven kings of Rome, Tarquin the Proud, was deposed and a system based on annually elected magistrates and various representative assemblies was established. A constitution set a series of checks and balances, and a separation of powers. The most important magistrates were the two consuls, who together exercised executive authority such as imperium, or military command. The consuls had to work with the Senate, which was initially an advisory council of the ranking nobility, or patricians, but grew in size and power.

Other magistrates of the Republic include tribunes, quaestors, aediles, praetors and censors. The magistracies were originally restricted to patricians, but were later opened to common people, or plebeians. Republican voting assemblies included the comitia centuriata ('centuriate assembly'), which voted on matters of war and peace and elected men to the most important offices, and the comitia tributa ('tribal assembly'), which elected less important offices.

In the 4th century BC, Rome had come under attack by the Gauls, who now extended their power in the Italian peninsula beyond the Po Valley and through Etruria. On 16 July 390 BC, a Gallic army under the leadership of tribal chieftain Brennus, defeated the Romans at the Battle of the Allia and marched to Rome. The Gauls looted and burned the city, then laid siege to the Capitoline Hill, where some Romans had barricaded themselves, for seven months. The Gauls then agreed to give the Romans peace in exchange for 1000 pounds of gold. According to later legend, the Roman supervising the weighing noticed that the Gauls were using false scales. The Romans then took up arms and defeated the Gauls. Their victorious general Camillus remarked "With iron, not with gold, Rome buys her freedom."

The Romans gradually subdued the other peoples on the Italian peninsula, including the Etruscans. The last threat to Roman hegemony in Italy came when Tarentum, a major Greek colony, enlisted the aid of Pyrrhus of Epirus in 281 BC, but this effort failed as well. The Romans secured their conquests by founding Roman colonies in strategic areas, thereby establishing stable control over the region.

In the 3rd century BC Rome faced a new and formidable opponent: Carthage, the other major power in the Western Mediterranean. The First Punic War began in 264 BC, when the city of Messana asked for Carthage's help in their conflicts with Hiero II of Syracuse. After the Carthaginian intercession, Messana asked Rome to expel the Carthaginians. Rome entered this war because Syracuse and Messana were too close to the newly conquered Greek cities of Southern Italy and Carthage was now able to make an offensive through Roman territory; along with this, Rome could extend its domain over Sicily.

Carthage was a maritime power, and the Roman lack of ships and naval experience made the path to the victory a long and difficult one for the Roman Republic. Despite this, after more than 20 years of war, Rome defeated Carthage and a peace treaty was signed. Among the reasons for the Second Punic War was the subsequent war reparations Carthage acquiesced to at the end of the First Punic War. The war began with the audacious invasion of Hispania by Hannibal, who marched through Hispania to the Italian Alps. Hannibal's invasion lasted over 16 years, ravaging Italy, but ultimately Carthage was defeated in the decisive Battle of Zama in October 202 BC.

More than a half century after these events, Carthage was left humiliated and the Republic's focus was now directed towards the Hellenistic kingdoms of Greece and revolts in Hispania. However, Carthage, having paid the war indemnity, felt that its commitments and submission to Rome had ceased, a vision not shared by the Roman Senate. The Third Punic War began when Rome declared war against Carthage in 149 BC. Carthage resisted well at the first strike but could not withstand the attack of Scipio Aemilianus, who entirely destroyed the city, enslaved all the citizens and gained control of that region, which became the province of Africa. All these wars resulted in Rome's first overseas conquests (Sicily, Hispania and Africa) and the rise of Rome as a significant imperial power.

After defeating the Macedonian and Seleucid Empires in the 2nd century BC, the Romans became the dominant people of the Mediterranean Sea. The conquest of the Hellenistic kingdoms brought the Roman and Greek cultures in closer contact and the Roman elite, once rural, became cosmopolitan.

Foreign dominance led to internal strife. Senators became rich at the provinces' expense; soldiers, who were mostly small-scale farmers, were away from home longer and could not maintain their land; and the increased reliance on foreign slaves and the growth of latifundia reduced the availability of paid work. Income from war booty, mercantilism in the new provinces, and tax farming created new economic opportunities for the wealthy, forming a new class of merchants, called the equestrians. The lex Claudia forbade members of the Senate from engaging in commerce, so while the equestrians could theoretically join the Senate, they were severely restricted in political power. The Senate squabbled perpetually, repeatedly blocked important land reforms and refused to give the equestrian class a larger say in the government.

Violent gangs of the urban unemployed, controlled by rival Senators, intimidated the electorate through violence. The situation came to a head in the late 2nd century BC under the Gracchi brothers, a pair of tribunes who attempted to pass land reform legislation that would redistribute the major patrician landholdings among the plebeians. Both brothers were killed and the Senate passed reforms reversing the Gracchi brother's actions. This led to the growing divide of the plebeian groups (populares) and equestrian classes (optimates).

Gaius Marius soon became a leader of the Republic, holding the first of his seven consulships (an unprecedented number) in 107 BC by arguing that his former patron Quintus Caecilius Metellus Numidicus was not able to defeat and capture the Numidian king Jugurtha. Marius then started his military reform: in his recruitment to fight Jugurtha, he levied the very poor (an innovation), and many landless men entered the army. Marius was elected for five consecutive consulships from 104 to 100 BC, as Rome needed a military leader to defeat the Cimbri and the Teutones, who were threatening Rome. After Marius's retirement, Rome had a brief peace, during which the Italian socii ('allies') requested Roman citizenship and voting rights. The reformist Marcus Livius Drusus supported their legal process but was assassinated, and the socii revolted against the Romans in the Social War. At one point both consuls were killed; Marius was appointed to command the army together with Lucius Julius Caesar and Lucius Cornelius Sulla.

By the end of the Social War, Marius and Sulla were the premier military men in Rome and their partisans were in conflict, both sides jostling for power. In 88 BC, Sulla was elected for his first consulship and his first assignment was to defeat Mithridates VI of Pontus, whose intentions were to conquer the Eastern part of the Roman territories. However, Marius's partisans managed his installation to the military command, defying Sulla and the Senate. To consolidate his own power, Sulla conducted a surprising and illegal action: he marched to Rome with his legions, killing all those who showed support to Marius's cause. In the following year, 87 BC, Marius, who had fled at Sulla's march, returned to Rome while Sulla was campaigning in Greece. He seized power along with the consul Lucius Cornelius Cinna and killed the other consul, Gnaeus Octavius, achieving his seventh consulship. Marius and Cinna revenged their partisans by conducting a massacre.

Marius died in 86 BC, due to age and poor health, just a few months after seizing power. Cinna exercised absolute power until his death in 84 BC. After returning from his Eastern campaigns, Sulla had a free path to reestablish his own power. In 83 BC he made his second march on Rome and began a time of terror: thousands of nobles, knights and senators were executed. Sulla held two dictatorships and one more consulship, which began the crisis and decline of Roman Republic.

In the mid-1st century BC, Roman politics were restless. Political divisions in Rome split into one of two groups, populares (who hoped for the support of the people) and optimates (the 'best', who wanted to maintain exclusive aristocratic control). Sulla overthrew all populist leaders and his constitutional reforms removed powers (such as those of the tribune of the plebs) that had supported populist approaches.

The imperial city of Rome was the largest urban centre in the empire, with a population variously estimated from 450,000 to close to one million. Around 20% of the population under jurisdiction of ancient Rome (25–40%, depending on the standards used, in Roman Italy) lived in innumerable urban centres, with population of 10,000 and more and several military settlements, a very high rate of urbanisation by pre-industrial standards. Most of those centres had a forum, temples, and other buildings similar to Rome's. The average life expectancy in the Middle Empire was about 26–28 years.

The roots of the legal principles and practices of the ancient Romans may be traced to the Law of the Twelve Tables promulgated in 449 BC and to the codification of law issued by order of Emperor Justinian I around 530 AD (see Corpus Juris Civilis). Roman law, as preserved in Justinian's codes, continued into the Byzantine Roman Empire and formed the basis of similar codifications in continental Western Europe. Roman law continued, in a broader sense, to be applied throughout most of Europe until the end of the 17th century.

The major divisions of the law of ancient Rome, as contained within the Justinian and Theodosian law codes, consisted of Jus civile, Jus gentium, and Jus naturale. The Jus civile ('citizen law') was the body of common laws that applied to Roman citizens. The praetores urbani (sing. Praetor Urbanus) were the people who had jurisdiction over cases involving citizens. The Jus gentium ('law of nations') was the body of common laws that applied to foreigners and their dealings with Roman citizens. The praetores peregrini (sing. Praetor Peregrinus) were the people who had jurisdiction over cases involving citizens and foreigners. Jus naturale encompassed natural law, the body of laws that were considered common to all beings.

Roman society is largely viewed as hierarchical, with slaves (servi) at the bottom, freedmen (liberti) above them, and free-born citizens (cives) at the top. Free citizens were subdivided by class. The broadest, and earliest, division was between the patricians, who could trace their ancestry to one of the 100 patriarchs at the founding of the city, and the plebeians, who could not. This became less important in the later Republic, as some plebeian families became wealthy and entered politics, and some patrician families fell economically. Anyone, patrician or plebeian, who could count a consul as his ancestor was a noble (nobilis); a man who was the first of his family to hold the consulship, such as Marius or Cicero, was known as a novus homo ('new man') and ennobled his descendants. Patrician ancestry, however, still conferred considerable prestige, and many religious offices remained restricted to patricians.

A class division originally based on military service became more important. Membership of these classes was determined periodically by the censors, according to property. The wealthiest were the Senatorial class, who dominated politics and command of the army. Next came the equestrians (equites, sometimes translated "knights"), originally those who could afford a warhorse, and who formed a powerful mercantile class. Several further classes, originally based on the military equipment their members could afford, followed, with the proletarii, citizens who had no property other than their children, at the bottom. Before the reforms of Marius they were ineligible for military service and are often described as being just above freed slaves in wealth and prestige.

Voting power in the Republic depended on class. Citizens were enrolled in voting "tribes", but the tribes of the richer classes had fewer members than the poorer ones, all the proletarii being enrolled in a single tribe. Voting was done in class order, from top down, and stopped as soon as most of the tribes had been reached, so the poorer classes were often unable to cast their votes.

Women in ancient Rome shared some basic rights with their male counterparts, but were not fully regarded as citizens and were thus not allowed to vote or take part in politics. At the same time the limited rights of women were gradually expanded (due to emancipation) and women reached freedom from pater familias, gained property rights and even had more juridical rights than their husbands, but still no voting rights, and were absent from politics.

Allied foreign cities were often given the Latin Rights, an intermediary level between full citizens and foreigners (peregrini), which gave their citizens rights under Roman law and allowed their leading magistrates to become full Roman citizens. While there were varying degrees of Latin rights, the main division was between those cum suffragio ('with vote'; enrolled in a Roman tribe and able to take part in the comitia tributa) and sine suffragio ('without vote'; could not take part in Roman politics). Most of Rome's Italian allies were given full citizenship after the Social War of 91–88 BC, and full Roman citizenship was extended to all free-born men in the Empire by Caracalla in 212, with the exception of the dediticii, people who had become subject to Rome through surrender in war, and freed slaves.

In the early Republic, there were no public schools, so boys were taught to read and write by their parents, or by educated slaves, called paedagogi, usually of Greek origin. The primary aim of education during this period was to train young men in agriculture, warfare, Roman traditions, and public affairs. Young boys learned much about civic life by accompanying their fathers to religious and political functions, including the Senate for the sons of nobles. The sons of nobles were apprenticed to a prominent political figure at the age of 16, and campaigned with the army from the age of 17. Educational practices were modified after the conquest of the Hellenistic kingdoms in the 3rd century BC and the resulting Greek influence, although Roman educational practices were still much different from Greek ones. If their parents could afford it, boys and some girls at the age of 7 were sent to a private school outside the home called a ludus, where a teacher (called a litterator or a magister ludi, and often of Greek origin) taught them basic reading, writing, arithmetic, and sometimes Greek, until the age of 11.

Beginning at age 12, students went to secondary schools, where the teacher (now called a grammaticus) taught them about Greek and Roman literature. At the age of 16, some students went on to rhetoric school (where the teacher, usually Greek, was called a rhetor). Education at this level prepared students for legal careers, and required that the students memorise the laws of Rome.

Initially, Rome was ruled by kings, who were elected from each of Rome's major tribes in turn. The exact nature of the king's power is uncertain. He may have held near-absolute power, or may have merely been the chief executive of the Senate and the people. In military matters, the king's authority (Imperium) was likely absolute. He was also the head of the state religion. In addition to the authority of the King, there were three administrative assemblies: the Senate, which acted as an advisory body for the King; the Comitia Curiata, which could endorse and ratify laws suggested by the King; and the Comitia Calata, which was an assembly of the priestly college that could assemble the people to bear witness to certain acts, hear proclamations, and declare the feast and holiday schedule for the next month.

The class struggles of the Roman Republic resulted in an unusual mixture of democracy and oligarchy. The word republic comes from the Latin res publica, which literally translates to 'public business'. Roman laws traditionally could only be passed by a vote of the Popular assembly (Comitia Tributa). Likewise, candidates for public positions had to run for election by the people. However, the Roman Senate represented an oligarchic institution, which acted as an advisory body.

In the Republic, the Senate held actual authority (auctoritas), but no real legislative power; it was technically only an advisory council. However, as the Senators were individually very influential, it was difficult to accomplish anything against the collective will of the Senate. New senators were chosen from among the most accomplished patricians by censors (Censura), who could also remove a senator from his office if he was found "morally corrupt". Later, under the reforms of the dictator Sulla, quaestors were made automatic members of the Senate, though most of his reforms did not survive.

The Republic had no fixed bureaucracy, and collected taxes through the practice of tax farming. Government positions such as quaestor, aedile, or praefect were funded by the office-holder. To prevent any citizen from gaining too much power, new magistrates were elected annually and had to share power with a colleague. For example, under normal conditions, the highest authority was held by two consuls. In an emergency, a temporary dictator could be appointed. Throughout the Republic, the administrative system was revised several times to comply with new demands. In the end, it proved inefficient for controlling the ever-expanding dominion of Rome, contributing to the establishment of the Roman Empire.

In the early Empire, the pretence of a republican form of government was maintained. The Roman emperor was portrayed as only a princeps, or 'first citizen', and the Senate gained legislative power and all legal authority previously held by the popular assemblies. However, the rule of the Emperors became increasingly autocratic, and the Senate was reduced to an advisory body appointed by the Emperor. The Empire did not inherit a set bureaucracy from the Republic, since the Republic did not have any permanent governmental structures apart from the Senate. The Emperor appointed assistants and advisers, but the state lacked many institutions, such as a centrally planned budget. Some historians have cited this as a significant reason for the decline of the Roman Empire.

The early Roman army (c. 500 BC) was, like those of other contemporary city-states influenced by Greek civilisation, a citizen militia that practised hoplite tactics. It was small and organised in five classes (in parallel to the comitia centuriata, the body of citizens organised politically), with three providing hoplites and two providing light infantry. The early Roman army was tactically limited and its stance during this period was essentially defensive.

By the 3rd century BC, the Romans abandoned the hoplite formation in favour of a more flexible system in which smaller groups of 120 (or sometimes 60) men called 'maniples could manoeuvre more independently on the battlefield. Thirty maniples arranged in three lines with supporting troops constituted a legion, totalling between 4,000 and 5,000 men. The early Republican legion consisted of five sections: manipular heavy infantry (hastati, principes and triarii), a force of light infantry (velites), and the cavalry (equites). With the new organisation came a new orientation toward the offensive and a much more aggressive posture toward adjoining city-states.

Until the late Republican period, the typical legionary was a property-owning citizen farmer from a rural area (an adsiduus) who served for particular (often annual) campaigns, and who supplied his own equipment. After 200 BC, economic conditions in rural areas deteriorated as manpower needs increased, so that the property qualifications for compulsory service were gradually reduced. Beginning in the 3rd century BC, legionaries were paid a stipend. By the time of Augustus, the ideal of the citizen-soldier had been abandoned and the legions had become fully professional. At the end of the Civil War, Augustus reorganised Roman military forces, discharging soldiers and disbanding legions.

Life in ancient Rome revolved around the city of Rome, located on seven hills. The city had a vast number of monumental structures like the Colosseum, the Trajan's Forum and the Pantheon. It had theatres, gymnasiums, marketplaces, functional sewers, bath complexes complete with libraries and shops, and fountains with fresh drinking water supplied by hundreds of miles of aqueducts. Throughout the territory under the control of ancient Rome, residential architecture ranged from modest houses to country villas.

In Rome, there were imperial residences on Palatine Hill. The low plebeian and middle equestrian classes lived in the city centre, packed into apartments, or insulae, which were almost like modern ghettos. These areas, often built by upper class property owners to rent, were often centred upon collegia or taberna. These people, provided with a free supply of grain, and entertained by gladiatorial games, were enrolled as clients of patrons among the upper class patricians, whose assistance they sought and whose interests they upheld.

The native language of the Romans was Latin, an Italic language the grammar of which relies little on word order, conveying meaning through a system of affixes attached to word stems. Its alphabet was based on the Etruscan alphabet, which was in turn based on the Greek alphabet. Although surviving Latin literature consists almost entirely of Classical Latin, an artificial and highly stylised and polished literary language from the 1st century BC, the spoken language of the Roman Empire was Vulgar Latin, which significantly differed from Classical Latin in grammar and vocabulary, and eventually in pronunciation. Speakers of Latin could understand both until the 7th century when spoken Latin began to diverge so much that 'Classical' or 'Good Latin' had to be learned as a second language.

While Latin remained the main written language of the Roman Empire, Greek came to be the language spoken by the well-educated elite, as most of the literature studied by Romans was written in Greek. Most of the emperors were bilingual but had a preference for Latin in the public sphere for political reasons, a practice that first started during the Punic wars. In the eastern part of the Roman Empire (and later the Eastern Roman Empire), Latin was never able to replace Greek, a legacy of the Hellenistic period. Justinian would be the last emperor to use Latin in government and marks when Greek officially took over. The expansion of the Roman Empire spread Latin throughout Europe, and Vulgar Latin evolved into many distinct Romance languages.

Archaic Roman religion, at least concerning the gods, was made up not of written narratives, but rather of complex interrelations between gods and humans. Unlike in Greek mythology, the gods were not personified, but were vaguely defined sacred spirits called numina. Romans also believed that every person, place or thing had its own genius, or divine soul. During the Roman Republic, Roman religion was organised under a strict system of priestly offices, which were held by men of senatorial rank. The College of Pontifices was uppermost body in this hierarchy, and its chief priest, the Pontifex Maximus, was the head of the state religion. Flamens took care of the cults of various gods, while augurs were trusted with taking the auspices. The sacred king took on the religious responsibilities of the deposed kings. In the Roman Empire, deceased emperors who had ruled well were deified by their successors and the Senate. and the formalised imperial cult became increasingly prominent.

As contact with the Greeks increased, the old Roman gods became increasingly associated with Greek gods. Under the Empire, the Romans absorbed the mythologies of their conquered subjects, often leading to situations in which the temples and priests of traditional Italian deities existed side by side with those of foreign gods.

Beginning with Emperor Nero in the 1st century AD, Roman official policy towards Christianity was negative, and at some point, being a Christian could be punishable by death. Under Emperor Diocletian, the persecution of Christians reached its peak. However, it became an officially supported religion in the Roman state under Diocletian's successor, Constantine I, with the signing of the Edict of Milan in 313, and quickly became dominant. All religions except Christianity were prohibited in 391 AD by an edict of Emperor Theodosius I.

Like many ancient cultures, concepts of ethics and morality, while sharing some commonalities with modern society, differed greatly in several important ways. Because ancient civilisations like Rome were under constant threat of attack from marauding tribes, their culture was necessarily militaristic with martial skills being a prized attribute. Whereas modern societies consider compassion a virtue, Roman society considered it a vice, a moral defect. One of the primary purposes of the gladiatorial games was to inoculate Roman citizens from this weakness. Romans instead prized virtues such as courage and conviction (virtus), a sense of duty to one's people, moderation and avoiding excess (moderatio), forgiveness and understanding (clementia), fairness (severitas), and loyalty (pietas).

Roman society had well-established and restrictive norms related to sexuality, though as with many societies, the lion's share of the responsibilities fell on women. Women were generally expected to be monogamous having only a single husband during their life (univira), though this was much less regarded by the elite, especially under the empire. Women were expected to be modest in public avoiding any provocative appearance and to demonstrate absolute fidelity to their husbands (pudicitia). Wearing a veil was a common expectation to preserve modesty. Sex outside of marriage was generally frowned upon for men and women and was made illegal during the imperial period. Nevertheless, prostitution was an accepted and regulated practice.

Public demonstrations of death, violence, and brutality were used as a source of entertainment in Roman communities; however it was also a way to maintain social order, demonstrate power, and signify communal unity.

Roman painting styles show Greek influences, and surviving examples are primarily frescoes used to adorn the walls and ceilings of country villas, though Roman literature includes mentions of paintings on wood, ivory, and other materials. Several examples of Roman painting have been found at Pompeii, and from these art historians divide the history of Roman painting into four periods.

The first style of Roman painting was practised from the early 2nd century BC to the early- or mid-1st century BC. It was mainly composed of imitations of marble and masonry, though sometimes including depictions of mythological characters.

The second style began during the early 1st century BC and attempted to depict realistically three-dimensional architectural features and landscapes. The third style occurred during the reign of Augustus (27 BC – 14 AD), and rejected the realism of the second style in favour of simple ornamentation. A small architectural scene, landscape, or abstract design was placed in the centre with a monochrome background. The fourth style, which began in the 1st century AD, depicted scenes from mythology, while retaining architectural details and abstract patterns.

Portrait sculpture used youthful and classical proportions, evolving later into a mixture of realism and idealism. During the Antonine and Severan periods, ornate hair and bearding, with deep cutting and drilling, became popular. Advancements were also made in relief sculptures, usually depicting Roman victories.

Roman music was largely based on Greek music, and played an important part in many aspects of Roman life. In the Roman military, musical instruments such as the tuba (a long trumpet) or the cornu were used to give various commands, while the buccina (possibly a trumpet or horn) and the lituus (probably an elongated J-shaped instrument), were used in ceremonial capacities. Music was used in the Roman amphitheatres between fights and in the odea, and in these settings is known to have featured the cornu and the hydraulis (a type of water organ). Most religious rituals featured musical performances. Some music historians believe that music was used at almost all public ceremonies.

The graffiti, brothels, paintings, and sculptures found in Pompeii and Herculaneum suggest that the Romans had a sex-saturated culture.

Latin literature was, from its start, influenced heavily by Greek authors. Some of the earliest extant works are of historical epics telling the early military history of Rome. As the Republic expanded, authors began to produce poetry, comedy, history, and tragedy.

Ancient Rome's literary contributions are still recognised today and the works by ancient Roman authors were available in bookshops as well as in public and private libraries. Many scholars and statesmen of ancient Rome cultivated private libraries that were used both as demonstrations of knowledge and displays of wealth and power.

Although Julius Caesar had intended to establish public libraries to further establish Rome as a great cultural centre like Athens and Alexandria, he died before this was accomplished. Caesar's former lieutenant, Gaius Asinius Pollio, took up the project and opened the first public library in Rome in the Atrium Libertatis. Emperors Augustus, Tiberius, Vespasian, Domitian, and Trajan also founded or expanded public libraries in Rome during their reigns. These included the Ulpian Library in Trajan's Forum and libraries in the Temple of Apollo Palatinus, the Temple of Peace in the Roman Forum, the Temple of Divus Augustus, which was dedicated to Minerva when it was rebuilt under Emperor Domitian's orders. By the fall of the Western Roman Empire, the city of Rome had more than two dozen public libraries. As the Roman Empire spread, public libraries were established in other major cities and cultural centres including Ephesos, Athens, and Timgad.

Ancient Roman cuisine changed over the long duration of this ancient civilisation. Dietary habits were affected by the influence of Greek culture, the political changes from Kingdom to Republic to Empire, and the Empire's enormous expansion, which exposed Romans to many new, provincial culinary habits and cooking techniques. In the beginning the differences between social classes were relatively small, but disparities evolved with the Empire's growth. Men and women drank wine with their meals.

The ancient Roman diet included many items that are staples of modern Italian cooking. Pliny the Elder discussed more than 30 varieties of olive, 40 kinds of pear, figs (native and imported from Africa and the eastern provinces), and a wide variety of vegetables, including carrots (of different colours, but not orange) as well as celery, garlic, some flower bulbs, cabbage and other brassicas (such as kale and broccoli), lettuce, endive, onion, leek, asparagus, radishes, turnips, parsnips, beets, green peas, chard, cardoons, olives, and cucumber.

However, some foods now considered characteristic of modern Italian cuisine were not used. In particular, spinach and eggplant (aubergine) were introduced later from the Arab world, and tomatoes, potatoes, capsicum peppers, and maize (the modern source of polenta) only appeared in Europe following the discovery of the New World and the Columbian Exchange. The Romans knew of rice, but it was very rarely available to them. There were also few citrus fruits.

Butcher's meat such as beef was an uncommon luxury. The most popular meat was pork, especially sausages. Fish was more common than meat, with a sophisticated aquaculture and large-scale industries devoted to oyster farming. The Romans also engaged in snail farming and oak grub farming.

Ancient Rome boasted impressive technological feats, using many advancements that were lost in the Middle Ages and not rivalled again until the 19th and 20th centuries. An example of this is insulated glazing, which was not invented again until the 1930s. Many practical Roman innovations were adopted from earlier Greek designs. Advancements were often divided and based on craft. Artisans guarded technologies as trade secrets.

Roman civil engineering and military engineering constituted a large part of Rome's technological superiority and legacy, and contributed to the construction of hundreds of roads, bridges, aqueducts, public baths, theatres and arenas. Many monuments, such as the Colosseum, Pont du Gard, and Pantheon, remain as testaments to Roman engineering and culture.

The Romans were renowned for their architecture, which is grouped with Greek traditions into "Classical architecture". Although there were many differences from Greek architecture, Rome borrowed heavily from Greece in adhering to strict, formulaic building designs and proportions. Aside from two new orders of columns, composite and Tuscan, and from the dome, which was derived from the Etruscan arch, Rome had relatively few architectural innovations until the end of the Republic.

In the 1st century BC, Romans started to use Roman concrete widely. Concrete was invented in the late 3rd century BC. It was a powerful cement derived from pozzolana, and soon supplanted marble as the chief Roman building material and allowed many daring architectural forms. Also in the 1st century BC, Vitruvius wrote De architectura, possibly the first complete treatise on architecture in history.

The Romans also largely built using timber, causing a rapid decline of the woodlands surrounding Rome. The first evidence of long-distance wood trading come from the discovery of wood planks, felled between AD 40 and 60, coming from the Jura mountains in northeastern France and ending up more than 1,055 miles (1,700 km) away, in the foundations of a lavish portico that was part of a vast wealthy patrician villa, in Central Rome. It is suggested that timber, around 4 metres (13 ft) long, came up to Rome via the Tiber River on ships travelling across the Mediterranean Sea from the confluence of the Saône and Rhône rivers in what is now the city of Lyon in present-day France.

With solid foundations and good drainage, Roman roads were known for their durability and many segments of the Roman road system were still in use a thousand years after the fall of Rome. The construction of a vast and efficient travel network throughout the Empire dramatically increased Rome's power and influence. They allowed Roman legions to be deployed rapidly, with predictable marching times between key points of the empire, no matter the season. These highways also had enormous economic significance, solidifying Rome's role as a trading crossroads—the origin of the saying "all roads lead to Rome". The Roman government maintained a system of way stations, known as the cursus publicus, and established a system of horse relays allowing a dispatch to travel up to 80 km (50 mi) a day.

The Romans constructed numerous aqueducts to supply water to cities and industrial sites and to aid in their agriculture. By the third century, the city of Rome was supplied by 11 aqueducts with a combined length of 450 km (280 mi). The Romans also made major advancements in sanitation. Romans were particularly famous for their public baths, called thermae, which were used for both hygienic and social purposes. Many Roman houses had flush toilets and indoor plumbing, and a complex sewer system, the Cloaca Maxima, was used to drain the local marshes and carry waste into the Tiber. Some historians have speculated that lead pipes in the sewer and plumbing systems led to widespread lead poisoning, which contributed to fall of Rome; however, lead content would have been minimised.

Ancient Rome is the progenitor of Western civilisation. The customs, religion, law, technology, architecture, political system, military, literature, languages, alphabet, government and many factors and aspects of western civilisation are all inherited from Roman advancements. The rediscovery of Roman culture revitalised Western civilisation, playing a role in the Renaissance and the Age of Enlightenment.

The two longest ancient accounts of the Roman history, the histories of Livy and Dionysius of Halicarnassus, were composed 500 years later than the date for the founding of the republic and 200 years from the defeat of Hannibal. Although there has been a diversity of works on ancient Roman history, many of them are lost. As a result of this loss, there are gaps in Roman history, which are filled by unreliable works, such as the Historia Augusta. Caesar wrote his own accounts of his military campaigns in Gaul and during the Civil War in part to impress his contemporaries.

In the Empire, the biographies of famous men and early emperors flourished, examples being The Twelve Caesars of Suetonius, and Plutarch's Parallel Lives. Other major works of Imperial times were that of Livy and Tacitus.

Interest in studying, and idealising, ancient Rome became prevalent during the Italian Renaissance. Edward Gibbon's The History of the Decline and Fall of the Roman Empire "began the modern study of Roman history in the English-speaking world". Barthold Georg Niebuhr was a founder of the examination of ancient Roman history and wrote The Roman History, tracing the period until the First Punic War. During the Napoleonic, The History of Romans by Victor Duruy highlighted the Caesarean period popular at the time. History of Rome, Roman constitutional law and Corpus Inscriptionum Latinarum, all by Theodor Mommsen, became milestones.
