171-675: In the Roman tradition, oaths were sworn upon Iuppiter Lapis or the Jupiter Stone located in the Temple of Jupiter , Capitoline Hill . Iuppiter Lapis was held in the Roman tradition to be an Oath Stone , an aspect of Jupiter in his role as divine lawmaker responsible for order and used principally for the investiture of the oathtaking of office. According to Cyril Bailey, in "The Religion of Ancient Rome" (1907): We have, for instance,

342-582: A groma , a relatively simple apparatus that was eventually displaced by the more sophisticated dioptra , a precursor of the modern theodolite . In Book 8 of his De architectura , Vitruvius describes the need to ensure a constant supply, methods of prospecting, and tests for potable water. Greek and Roman physicians were well aware of the association between stagnant or tainted waters and water-borne diseases, and held rainwater to be water's purest and healthiest form, followed by springs. Rome's public baths, ostensibly one of Rome's greatest contributions to

513-626: A classical republic and then to an increasingly autocratic military dictatorship during the Empire. Ancient Rome is often grouped into classical antiquity together with ancient Greece , and their similar cultures and societies are known as the Greco-Roman world . Ancient Roman civilisation has contributed to modern language, religion, society, technology, law, politics, government, warfare, art, literature, architecture, and engineering. Rome professionalised and expanded its military and created

684-510: A "never failing" spring, stream or river; but acknowledges that not every farm did. Farmland without a reliable summer water-source was virtually worthless. During the growing season, a "modest local" irrigation system might consume as much water as the city of Rome; and the livestock whose manure fertilised the fields must be fed and watered all year round. At least some Roman landowners and farmers relied in part or whole on aqueduct water to raise crops as their primary or sole source of income but

855-686: 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

1026-406: A Republic. Augustus ( r.  27 BC – AD 14 ) gathered almost all the republican powers under his official title, princeps , and diminished the political influence of the senatorial class by boosting the equestrian class . The senators lost their right to rule certain provinces, like Egypt, since the governor of that province was directly nominated by the emperor. The creation of

1197-507: A banquet for its notable citizens, after which his soldiers killed all the guests. From the security of the temple of Sarapis, he then directed an indiscriminate slaughter of Alexandria's people. In 212, he issued the Edict of Caracalla , giving full Roman citizenship to all free men living in the Empire, with the exception of the dediticii , people who had become subject to Rome through surrender in war, and freed slaves. Mary Beard points to

1368-425: A cash income through the sale of surplus foodstuffs, and an increase in the value of the land itself. In the countryside, permissions to draw aqueduct water for irrigation were particularly hard to get; the exercise and abuse of such rights were subject to various known legal disputes and judgements, and at least one political campaign; in 184 BC Cato tried to block all unlawful rural outlets, especially those owned by

1539-436: A commensurate water-fee. Some individuals were gifted a right to draw overflow water gratis , as a State honour or grant; pipe stamps show that around half Rome's water grants were given to elite, extremely wealthy citizens of the senatorial class. Water grants were issued by the emperor or State to named individuals, and could not be lawfully sold along with a property, or inherited: new owners and heirs must therefore negotiate

1710-580: A continuous water-flow and the inevitable deposition of water-borne minerals within the pipes somewhat reduced the water's contamination by soluble lead. Lead content in Rome's aqueduct water was "clearly measurable, but unlikely to have been truly harmful". Nevertheless, the level of lead was 100 times higher than in local spring waters. Most Roman aqueducts were flat-bottomed, arch-section conduits, approximately 0.7 m (2.3 ft) wide and 1.5 m (5 ft) high internally, running 0.5 to 1 m beneath

1881-432: 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

2052-672: 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

2223-516: A hundred days. These games included gladiatorial combats , horse races and a sensational mock naval battle on the flooded grounds of the Colosseum. Titus died of fever in 81 AD, and was succeeded by his brother Domitian . As emperor, Domitian showed the characteristics of a tyrant . He ruled for fifteen years, during which time he acquired a reputation for self-promotion as a living god. He constructed at least two temples in honour of Jupiter,

2394-628: A large proletariat often of impoverished farmers. The latter groups supported the Catilinarian conspiracy —a resounding failure since the consul Marcus Tullius Cicero quickly arrested and executed the main leaders. Gaius Julius Caesar reconciled the two most powerful men in Rome: Marcus Licinius Crassus , who had financed much of his earlier career, and Crassus' rival, Gnaeus Pompeius Magnus (anglicised as Pompey), to whom he married his daughter . He formed them into

2565-466: A legal landscape at least as daunting as the physical one". In the aftermath of the Second Punic War , the censors exploited a legal process known as vindicatio , a repossession of private or tenanted land by the state, "restoring" it to a presumed ancient status as "public and sacred, and open to the people". Livy describes this as a public-spirited act of piety, and makes no reference to

2736-459: A local level, particularly when ager publicus was understood to be common property, to be used for whatever purpose seemed fit to its user. After ager publicus , minor, local roads and boundaries between adjacent private properties offered the least costly routes, though not always the most straightforward. Sometimes the State would purchase the whole of a property, mark out the intended course of

2907-538: A long time to reach the north west coast, and in 60 AD he finally crossed the Menai Strait to the sacred island of Mona ( Anglesey ), the last stronghold of the druids . His soldiers attacked the island and massacred the druids: men, women and children, destroyed the shrine and the sacred groves and threw many of the sacred standing stones into the sea. While Paulinus and his troops were massacring druids in Mona,

3078-415: A low "venter" bridge, then rose to a receiving tank at a slightly lower elevation. This discharged into another conduit; the overall gradient was maintained. Siphon pipes were usually made of soldered lead, sometimes reinforced by concrete encasements or stone sleeves. Less often, the pipes were stone or ceramic, jointed as male-female and sealed with lead. Vitruvius describes the construction of siphons and

3249-550: A maximum gradient of about 1:700) and Las Medulas in northern Spain . Where sharp gradients were unavoidable in permanent conduits, the channel could be stepped downwards, widened or discharged into a receiving tank to disperse the flow of water and reduce its abrasive force. The use of stepped cascades and drops also helped re-oxygenate and thus "freshen" the water. Some aqueduct conduits were supported across valleys or hollows on multiple piered arches of masonry, brick or concrete, also known as arcades . The Pont du Gard , one of

3420-710: 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" in Latin) 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

3591-426: A minor branch of the main aqueduct supplied a local suburb via a lead siphon whose "belly" was laid across a riverbed, eliminating any need for supporting bridgework. Some aqueducts running through hilly regions employed a combination of arcades, plain conduits buried at ground level, and tunnels large enough to contain the conduit, its builders and maintenance workers. The builders of Campana's Aqua Augusta changed

3762-500: A more conservative 520,000–635,000 m per day, supplying an estimated population of 1,000,000. Hundreds of aqueducts were built throughout the Roman Empire. Many of them have since collapsed or been destroyed, but a number of intact portions remain. The Zaghouan Aqueduct , 92.5 km (57.5 mi) in length, was built in the 2nd century AD to supply Carthage (in modern Tunisia ). Surviving provincial aqueduct bridges include

3933-429: A new grant, in their own name. In the event, these untransferable, personal water grants were more often transferred than not. Frontinus thought dishonest private users and corrupt state employees were responsible for most of the losses and outright thefts of water in Rome, and the worst damage to the aqueducts. His De aquaeductu can be read as a useful technical manual, a display of persuasive literary skills, and

4104-658: A new informal alliance including himself, the First Triumvirate ("three men"). Caesar's daughter died in childbirth in 54 BC, and in 53 BC, Crassus invaded Parthia and was killed in the Battle of Carrhae ; the Triumvirate disintegrated. Caesar conquered Gaul , obtained immense wealth, respect in Rome and the loyalty of battle-hardened legions. He became a threat to Pompey and was loathed by many optimates . Confident that Caesar could be stopped by legal means, Pompey's party tried to strip Caesar of his legions,

4275-519: 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 become a leader of the Republic, holding

4446-538: 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

4617-580: A prelude to Caesar's trial, impoverishment, and exile. To avoid this fate, Caesar crossed the Rubicon River and invaded Rome in 49 BC. The Battle of Pharsalus was a brilliant victory for Caesar and in this and other campaigns, he destroyed all of the optimates leaders: Metellus Scipio , Cato the Younger , and Pompey's son, Gnaeus Pompeius . Pompey was murdered in Egypt in 48 BC. Caesar

4788-438: A public aqueduct could draw, under license, a specified quantity of aqueduct water for irrigation at a predetermined time, using a bucket let into the conduit via the inspection hatches; this was intended to limit the depletion of water supply to users further down the gradient, and help ensure a fair distribution among competitors at the time when water was most needed and scarce. Columella recommends that any farm should contain

4959-412: A pull-through device. In Rome, where a hard-water supply was the norm, mains pipework was shallowly buried beneath road kerbs, for ease of access; the accumulation of calcium carbonate in these pipes would have necessitated their frequent replacement. Full closure of any aqueduct for servicing would have been a rare event, kept as brief as possible, with repair shut-downs preferably made when water demand

5130-930: A restoration by Vespasian and another, later, by his son Titus . To many modern scholars, the delay seems implausibly long. It might well have been thought politic to stress the personal generosity of the new Flavian dynasty , father and son, and exaggerate the negligence of their disgraced imperial predecessor, Nero , whose rebuilding priorities after Rome's Great Fire were thought models of self-indulgent ambition. Aqueduct mains could be directly tapped, but they more usually fed into public distribution terminals, known as castellum aquae ("water castles"), which acted as settling tanks and cisterns and supplied various branches and spurs, via lead or ceramic pipes. These pipes were made in 25 different standardised diameters and were fitted with bronze stopcocks. The flow from each pipe ( calix ) could be fully or partly opened, or shut down, and its supply diverted if necessary to any other part of

5301-619: A revolt in Mauretania and the Bar Kokhba revolt in Judea. This was the last large-scale Jewish revolt against the Romans, and was suppressed with massive repercussions in Judea. Hundreds of thousands of Jews were killed. Hadrian renamed the province of Judea " Provincia Syria Palaestina ", after one of Judea's most hated enemies. He constructed fortifications and walls, like the celebrated Hadrian's Wall which separated Roman Britannia and

5472-458: A rich Arabian city. Severus killed his legate, who was gaining respect from the legions; and his soldiers fell victim to famine. After this disastrous campaign, he withdrew. Severus also intended to vanquish the whole of Britannia. To achieve this, he waged war against the Caledonians . After many casualties in the army due to the terrain and the barbarians' ambushes, Severus himself went to

5643-646: 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 leaving again. They named the settlement after her. The Roman poet Virgil recounted this legend in his classical epic poem the Aeneid , where the Trojan prince Aeneas is destined to found a new Troy. Literary and archaeological evidence

5814-675: 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

5985-636: A slight overall downward gradient within conduits of stone, brick , concrete or lead; the steeper the gradient, the faster the flow. Most conduits were buried beneath the ground and followed the contours of the terrain; obstructing peaks were circumvented or, less often, tunneled through. Where valleys or lowlands intervened, the conduit was carried on bridgework , or its contents fed into high-pressure lead, ceramic, or stone pipes and siphoned across. Most aqueduct systems included sedimentation tanks, which helped to reduce any water-borne debris. Sluices , castella aquae (distribution tanks) and stopcocks regulated

6156-408: A state honour. In cities and towns, clean run-off water from aqueducts supported high consumption industries such as fulling and dyeing , and industries that employed water but consumed almost none, such as milling . Used water and water surpluses fed ornamental and market gardens, and scoured the drains and public sewers. Unlicensed rural diversion of aqueduct water for agriculture was common during

6327-697: A statue of Apollo and the temple of Divus Claudius ("the deified Claudius"), both initiated by Nero. Buildings destroyed by the Great Fire of Rome were rebuilt, and he revitalised the Capitol . Vespasian started the construction of the Flavian Amphitheater, commonly known as the Colosseum . The historians Josephus and Pliny the Elder wrote their works during Vespasian's reign. Vespasian

6498-546: A system of government called res publica , the inspiration for modern republics such as the United States and France . It achieved impressive technological and architectural feats, such as the empire-wide construction of aqueducts and roads , as well as more grandiose monuments and facilities. Archaeological evidence of settlement around Rome starts to emerge c.  1000 BC . Large-scale organisation appears only c.  800 BC , with

6669-497: 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

6840-439: A warning to users and his own staff that if they stole water, they would be found out, because he had all the relevant, expert calculations to hand. He claimed to know not only how much was stolen, but how it was done. Tampering and fraud were indeed commonplace; methods included the fitting of unlicensed or additional outlets, some of them many miles outside the city, and the illegal widening of lead pipes. Any of this might involve

7011-448: 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 sixth century BC; by its end, Rome controlled

7182-679: Is estimated between 780 and a little over 800 km, of which approximately 47 km (29 mi) were carried above ground level, on masonry supports. Most of Rome's water was carried by four of these: the Aqua Anio Vetus, the Aqua Marcia, the Aqua Claudia and the Aqua Anio Novus. Modern estimates of the city's supply, based on Frontinus' own calculations in the late 1st century, range from a high of 1,000,000 m per day to

7353-645: Is provincial Italy's Aqua Augusta . It supplied a great number of luxury coastal holiday-villas belonging to Rome's rich and powerful, several commercial fresh-water fisheries, market-gardens, vineyards and at least eight cities, including the major ports at Naples and Misenum ; sea voyages by traders and Rome's Republican and Imperial navies required copious on-board supplies of fresh water. Aqueducts were built to supply Roman military bases in Britain. The sites of permanent fortresses show traces of fountains and piped water, which were probably supplied by aqueducts from

7524-507: Is usually taken by historians as the beginning of Roman Empire. Officially, the government was republican, but Augustus assumed absolute powers. His reform of the government brought about a two-century period colloquially referred to by Romans as the Pax Romana . The Julio-Claudian dynasty was established by Augustus . The emperors of this dynasty were Augustus, Tiberius , Caligula , Claudius and Nero . The Julio-Claudians started

7695-689: The Historia Augusta give many accounts of his notorious extravagance. Elagabalus adopted his cousin Severus Alexander , as Caesar, but subsequently grew jealous and attempted to assassinate him. However, the Praetorian guard preferred Alexander, murdered Elagabalus, dragged his mutilated corpse through the streets of Rome, and threw it into the Tiber. Severus Alexander then succeeded him. Alexander waged war against many foes, including

7866-519: 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,

8037-664: The Aqua Marcia , was at first legally blocked on religious grounds, under advice from the decemviri (an advisory "board of ten"). The new aqueduct was meant to supply water to the highest elevations of the city, including the Capitoline Hill , but the decemviri had consulted Rome's main written oracle, the Sibylline Books , and found there a warning against supplying water to the Capitoline. This brought

8208-605: The Balkans , Crimea , and much of the Middle East, including Anatolia , Levant , and parts of Mesopotamia and Arabia . That empire was among the largest empires in the ancient world, covering around 5 million square kilometres (1.9 million square miles) in AD 117, with an estimated 50 to 90 million inhabitants, roughly 20% of the world's population at the time. The Roman state evolved from an elective monarchy to

8379-580: The Capitoline Hill . As demand grew still further, more aqueducts were built, including the Aqua Tepula in 127 BC and the Aqua Julia in 33 BC. Aqueduct building programmes in the city reached a peak in the Imperial Era; political credit and responsibility for provision of public water supplies passed from mutually competitive Republican political magnates to the emperors. Augustus' reign saw

8550-802: The Pont du Gard in France and the Aqueduct of Segovia in Spain. The longest single conduit, at over 240 km, is associated with the Valens Aqueduct of Constantinople. "The known system is at least two and half times the length of the longest recorded Roman aqueducts at Carthage and Cologne, but perhaps more significantly it represents one of the most outstanding surveying achievements of any pre-industrial society". Rivalling this in terms of length and possibly equaling or exceeding it in cost and complexity,

8721-665: The Praetorian Guard and his reforms in the military, creating a standing army with a fixed size of 28 legions, ensured his total control over the army. Compared with the Second Triumvirate's epoch, Augustus' reign as princeps was very peaceful, which led the people and the nobles of Rome to support Augustus, increasing his strength in political affairs. His generals were responsible for the field command, gaining such commanders as Marcus Vipsanius Agrippa , Nero Claudius Drusus and Germanicus much respect from

8892-649: The Roman naming conventions ) tried to align himself with the Caesarian faction. In 43 BC, along with Antony and Marcus Aemilius Lepidus , Caesar's best friend, he legally established the Second Triumvirate . Upon its formation, 130–300 senators were executed, and their property was confiscated, due to their supposed support for the Liberatores . In 42 BC, the Senate deified Caesar as Divus Iulius ; Octavian thus became Divi filius ,

9063-489: The censor Appius Claudius Caecus . The Aqua Appia was one of two major public projects of the time; the other was a military road between Rome and Capua , the first leg of the so-called Appian Way . Both projects had significant strategic value, as the Third Samnite War had been under way for some thirty years by that point. The road allowed rapid troop movements; and by design or fortunate coincidence, most of

9234-807: The "five good emperors" Nerva , Trajan , Hadrian , Antoninus Pius and Marcus Aurelius . Trajan, Hadrian, Antoninus Pius and Marcus Aurelius were part of Italic families settled in Roman colonies outside of Italy: the families of Trajan and Hadrian had settled in Italica ( Hispania Baetica ), that of Antoninus Pius in Colonia Agusta Nemausensis ( Gallia Narbonensis ), and that of Marcus Aurelius in Colonia Claritas Iulia Ucubi (Hispania Baetica). The Nerva-Antonine dynasty came to an end with Commodus , son of Marcus Aurelius. Nerva abdicated and died in 98 AD, and

9405-544: The "positively unwholesome" waters of the Aqua Alsietina were used to supply Trastevere's public fountains. The situation was finally ameliorated when the emperor Trajan built the Aqua Traiana in 109 AD, bringing clean water directly to Trastavere from aquifers around Lake Bracciano . By the late 3rd century AD, the city was supplied with water by eleven state-funded aqueducts. Their combined conduit length

9576-715: 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. At this time Rome was a consolidated empire—in the military view—and had no major enemies. 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

9747-525: The 69 km (42.8 mile) Aqua Claudia , which gave good quality water but failed on several occasions; and the Anio Novus , highest of all Rome's aqueducts and one of the most reliable but prone to muddy, discoloured waters, particularly after rain, despite its use of settling tanks. Most of Rome's aqueducts drew on various springs in the valley and highlands of the Anio, the modern river Aniene , east of

9918-726: The 8th century BC to the collapse of the Western Roman Empire in the 5th century AD. It encompasses the Roman Kingdom (753–509 BC), the Roman Republic (509–27 BC), and the Roman Empire (27 BC–476 AD) until the fall of the western empire. Ancient Rome began as an Italic settlement, traditionally dated to 753 BC, beside the River Tiber in the Italian Peninsula . The settlement grew into

10089-413: The Anio valley and its uplands. Spring water was fed into a stone or concrete springhouse, then entered the aqueduct conduit. Scattered springs would require several branch conduits feeding into a main channel. Some systems drew water from open, purpose-built, dammed reservoirs, such as the two (still in use) that supplied the aqueduct at the provincial city of Emerita Augusta . The territory over which

10260-465: The Aqua Appia ran within a buried conduit, relatively secure from attack. It was fed by a spring 16.4 km from Rome, and dropped 10 m over its length to discharge approximately 75,500 m of water each day into a fountain at Rome's cattle market, the Forum Boarium , one of the city's lowest-lying public spaces. A second aqueduct, the Aqua Anio Vetus , was commissioned some forty years later, funded by treasures seized from Pyrrhus of Epirus . Its flow

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

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

10773-473: The City of Rome's aqueducts, suffered at least two serious partial collapses over two centuries, one of them very soon after construction, and both probably due to a combination of shoddy workmanship, underinvestment, Imperial negligence, collateral damage through illicit outlets, natural ground tremors and damage by overwhelming seasonal floods originating upstream. Inscriptions claim that it was largely out of commission, and awaiting repair, for nine years prior to

Permanent auxiliary forts were supplied by aqueducts from the Flavian period, possibly co-incident with the regular demand for dependable water supplies by provincial military settlements equipped with bathhouses, once these were introduced. The plans for any public or private aqueduct had to be submitted to scrutiny by civil authorities. Permission was granted only if the proposal respected

11115-427: 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

11286-413: The Empire in 165–180 AD. From Nerva to Marcus Aurelius, the empire achieved an unprecedented status. The powerful influence of laws and manners had gradually cemented the union of the provinces. All the citizens enjoyed and abused the advantages of wealth. The image of a free constitution was preserved with decent reverence. The Roman senate appeared to possess the sovereign authority, and devolved on

11457-463: The Flavian period was the siege and destruction of Jerusalem in 70 AD by Titus . The destruction of the city was the culmination of the Roman campaign in Judea following the Jewish uprising of 66 AD. The Second Temple was completely demolished, after which Titus' soldiers proclaimed him imperator in honour of the victory. Jerusalem was sacked and much of the population killed or dispersed. Josephus claims that 1,100,000 people were killed during

11628-444: The Italian Alps , causing panic among Rome's Italian allies. The best way found to defeat Hannibal's purpose of causing the Italians to abandon Rome was to delay the Carthaginians with a guerrilla war of attrition, a strategy propounded by Quintus Fabius Maximus Verrucosus . 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

11799-411: The Mediterranean, Italy maintained a special status which made it domina provinciarum ("ruler of the provinces"), and – especially in relation to the first centuries of imperial stability – rectrix mundi ("governor of the world") and omnium terrarum parens ("parent of all lands"). The Flavians were the second dynasty to rule Rome. By 68 AD, the year of Nero's death, there

11970-506: The Roman Empire emulated this model, and funded aqueducts as objects of public interest and civic pride, "an expensive yet necessary luxury to which all could, and did, aspire". Most Roman aqueducts proved reliable and durable; some were maintained into the early modern era, and a few are still partly in use. Methods of aqueduct surveying and construction are noted by Vitruvius in his work De architectura (1st century BC). The general Frontinus gives more detail in his official report on

12141-479: The Romans throughout their history, but reliance on the water resources of a small catchment area restricted the city's potential for growth and security. The water of the River Tiber was close at hand, but would have been polluted by water-borne disease. Rome's aqueducts were not strictly Roman inventions – their engineers would have been familiar with the water-management technologies of Rome's Etruscan and Greek allies – but they proved conspicuously successful. By

12312-470: 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,

12483-463: The Tiber. A complex system of aqueduct junctions, tributary feeds and distribution tanks supplied every part of the city. Trastevere, the city region west of the Tiber, was primarily served by extensions of several of the city's eastern aqueducts, carried across the river by lead pipes buried in the roadbed of the river bridges, thus forming an inverted siphon . Whenever this cross-river supply had to be shut down for routine repair and maintenance works,

12654-573: 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

12825-436: The aqueduct ran had to be carefully surveyed to ensure the water would flow at a consistent and acceptable rate for the entire distance. Roman engineers used various surveying tools to plot the course of aqueducts across the landscape. They checked horizontal levels with a chorobates , a flatbedded wooden frame some 20 feet long, fitted with both a water level and plumblines. Horizontal courses and angles could be plotted using

12996-438: The aqueduct's eventual length, and thus to its cost. On rural land, a protective "clear corridor" was marked out with boundary slabs ( cippi ) usually 15 feet each side of the channel, reducing to 5 feet each side for lead pipes and in built-up areas. The conduits, their foundations and superstructures, were property of the State or emperor. The corridors were public land, with public rights of way and clear access to

13167-417: The aqueduct, and resell the unused land to help mitigate the cost. Graves and cemeteries, temples, shrines and other sacred places had to be respected; they were protected by law, and villa and farm cemeteries were often deliberately sited very close to public roadways and boundaries. Despite careful enquiries by planners, problems regarding shared ownership or uncertain legal status might emerge only during

13338-618: The architect Apollodorus of Damascus . He remodelled the Pantheon and extended the Circus Maximus . When Parthia appointed a king for Armenia without consulting Rome, Trajan declared war on Parthia and deposed the king of Armenia. In 115 he took the Northern Mesopotamian cities of Nisibis and Batnae , organised a province of Mesopotamia (116), and issued coins that claimed Armenia and Mesopotamia were under

13509-477: The arts and sciences, and bestowed honours and financial rewards upon the teachers of rhetoric and philosophy . On becoming emperor, Antoninus made few initial changes, leaving intact as far as possible the arrangements instituted by his predecessor. Antoninus expanded Roman Britannia by invading what is now southern Scotland and building the Antonine Wall . He also continued Hadrian's policy of humanising

13680-549: The authority of the Roman people. In that same year, he captured Seleucia and the Parthian capital Ctesiphon (near modern Baghdad ). After defeating a Parthian revolt and a Jewish revolt , he withdrew due to health issues, and in 117, he died of edema . Trajan's successor Hadrian withdrew all the troops stationed in Parthia, Armenia and Mesopotamia (modern-day Iraq ), abandoning Trajan's conquests. Hadrian's army crushed

13851-418: The basins and carried the water to their apartments; the better-off would have sent slaves to perform the same task. The outlet's elevation was too low to offer any city household or building a direct supply; the overflow drained into Rome's main sewer, and from there into the Tiber. Most inhabitants still relied on well water and rainwater. At this time, Rome had no public baths . The first was probably built in

14022-467: The baths, in particular, became important social centres. The majority of urban Romans lived in multi-storeyed blocks of flats ( insulae ). Some blocks offered water services, but only to tenants on the more expensive, lower floors; the other tenants would have drawn their water gratis from public fountains. During the Imperial era, lead production (mostly for pipes) became an Imperial monopoly, and

14193-448: The bore of pipe that led from the public water supply to their property – the wider the pipe, the greater the flow and the higher the fee. Some properties could be bought and sold with a legal right to draw water attached. Aqueduct officials could assign the right to draw overflow water ( aqua caduca , literally "fallen water") to certain persons and groups; fullers , for example, used a great deal of fresh water in their trade, in return for

14364-484: The bribery or connivance of unscrupulous aqueduct officials or workers. Archaeological evidence confirms that some users drew an illegal supply but not the likely quantity involved, nor the likely combined effect on supply to the city as a whole. The measurement of allowances was basically flawed; officially approved lead pipes carried inscriptions with information on the pipe's manufacturer, its fitter, and probably on its subscriber and their entitlement; but water allowance

14535-498: The building of the Aqua Virgo , and the short Aqua Alsietina . The latter supplied Trastevere with large quantities of non-potable water for its gardens and was used to create an artificial lake for staged sea-fights to entertain the populace. Another short Augustan aqueduct supplemented the Aqua Marcia with water of "excellent quality". The emperor Caligula added or began two aqueducts completed by his successor Claudius ;

14706-537: The changes to the calendar promoted by Caesar , and the month of August is named after him. Augustus brought a peaceful and thriving era to Rome, known as Pax Augusta or Pax Romana . Augustus died in 14 AD, but the empire's glory continued after his era. The Julio-Claudians continued to rule Rome after Augustus' death and remained in power until the death of Nero in 68 AD. Influenced by his wife, Livia Drusilla , Augustus appointed her son from another marriage, Tiberius , as his heir. The Senate agreed with

14877-562: The channel, presumably to prevent damage to the structure through erosion and water pressure. This value agrees well with the measured gradients of surviving masonry aqueducts. The gradient of the Pont du Gard is only 34 cm per km, descending only 17 m vertically in its entire length of 50 km (31 mi): it could transport up to 20,000 cubic metres a day. The gradients of temporary aqueducts used for hydraulic mining could be considerably greater, as at Dolaucothi in Wales (with

15048-471: 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 sixth century, Rome and many of its Italian neighbours entered

15219-758: The city and polity of Rome, and came to control its neighbours through a combination of treaties and military strength. It eventually controlled the Italian Peninsula, assimilating the Greek culture of southern Italy ( Magna Grecia ) and the Etruscan culture, and then became the dominant power in the Mediterranean region and parts of Europe. At its height it controlled the North African coast, Egypt , Southern Europe, and most of Western Europe,

15390-472: 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 third 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

15561-417: The conduit depended on the catchment hydrology – rainfall, absorption, and runoff – the cross section of the conduit, and its gradient; most conduits ran about two-thirds full. The conduit's cross section was also determined by maintenance requirements; workmen must be able to enter and access the whole, with minimal disruption to its fabric. Vitruvius recommends a low gradient of not less than 1 in 4800 for

15732-469: The conduits for maintenance. Within the corridors, potential sources of damage to the conduits were forbidden, including new roadways that crossed over the conduit, new buildings, ploughing or planting, and living trees, unless entirely contained by a building. The harvesting of hay and grass for fodder was permitted. Regulations and restrictions necessary to the aqueduct's long-term integrity and maintenance were not always readily accepted or easily enforced at

15903-785: The death of Tiberius, and, with belated support from the senators, proclaimed his uncle Claudius as the new emperor. Claudius was not as authoritarian as Tiberius and Caligula. Claudius conquered Lycia and Thrace ; his most important deed was the beginning of the conquest of Britannia . Claudius was poisoned by his wife, Agrippina the Younger in 54 AD. His heir was Nero , son of Agrippina and her former husband, since Claudius' son Britannicus had not reached manhood upon his father's death. Nero sent his general, Suetonius Paulinus , to invade modern-day Wales , where he encountered stiff resistance. The Celts there were independent, tough, resistant to tax collectors, and fought Paulinus as he battled his way across from east to west. It took him

16074-406: The destruction of republican values, but on the other hand, they boosted Rome's status as the central power in the Mediterranean region. While Caligula and Nero are usually remembered in popular culture as dysfunctional emperors, Augustus and Claudius are remembered as successful in politics and the military. This dynasty instituted imperial tradition in Rome and frustrated any attempt to reestablish

16245-406: The development of aqueduct technology, Romans, like most of their contemporaries in the ancient world, relied on local water sources such as springs and streams, supplemented by groundwater from privately or publicly owned wells, and by seasonal rain-water drained from rooftops into storage jars and cisterns . Such localised sources for fresh water – especially wells – were intensively exploited by

16416-465: The early Imperial era, the city's aqueducts helped support a population of over a million, and an extravagant water supply for public amenities had become a fundamental part of Roman life. The city's aqueducts and their dates of completion were: The city's demand for water had probably long exceeded its local supplies by 312 BC, when the city's first aqueduct, the Aqua Appia , was commissioned by

16587-592: The edict as a fundamental turning point, after which Rome was "effectively a new state masquerading under an old name". Macrinus conspired to have Caracalla assassinated by one of his soldiers during a pilgrimage to the Temple of the Moon in Carrhae, in 217 AD. Macrinus assumed power, but soon removed himself from Rome to the east and Antioch. His brief reign ended in 218, when the youngster Bassianus, high priest of

16758-470: The emperors all the executive powers of government. Gibbon declared the rule of these "Five Good Emperors" the golden era of the Empire. During this time, Rome reached its greatest territorial extent. Commodus , son of Marcus Aurelius, became emperor after his father's death. He is not counted as one of the Five Good Emperors, due to his direct kinship with the latter emperor; in addition, he

16929-526: The end of the Triumvirate, Antony was living in Ptolemaic Egypt , ruled by his lover, Cleopatra VII . Antony's affair with Cleopatra was seen as an act of treason, since she was queen of another country. Additionally, Antony adopted a lifestyle considered too extravagant and Hellenistic for a Roman statesman. Following Antony's Donations of Alexandria , which gave to Cleopatra the title of " Queen of Kings ", and to Antony's and Cleopatra's children

17100-492: The field. However, he became ill and died in 211 AD, at the age of 65. Upon the death of Severus, his sons Caracalla and Geta were made emperors. Caracalla had his brother, a youth, assassinated in his mother's arms, and may have murdered 20,000 of Geta's followers. Like his father, Caracalla was warlike. He continued Severus' policy and gained respect from the legions. Knowing that the citizens of Alexandria disliked him and were denigrating his character, Caracalla served

17271-678: 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 sixth century BC, the Romans were constructing the Temple of Jupiter Optimus Maximus on

17442-521: 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

17613-576: The first persecutor of Christians and for the Great Fire of Rome , rumoured to have been started by the emperor himself. A conspiracy against Nero in 65 AD under Calpurnius Piso failed, but in 68 AD the armies under Julius Vindex in Gaul and Servius Sulpicius Galba in modern-day Spain revolted. Deserted by the Praetorian Guards and condemned to death by the senate, Nero killed himself. As Roman provinces were being established throughout

17784-471: 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

17955-513: The fraction of aqueduct water involved can only be guessed at. More certainly, the creation of municipal and city aqueducts brought a growth in the intensive and efficient suburban market-farming of fragile, perishable commodities such as flowers (for perfumes, and for festival garlands), grapes, vegetables and orchard fruits; and of small livestock such as pigs and chickens, close to the municipal and urban markets. A licensed right to use aqueduct water on farmland could lead to increased productivity,

18126-474: The frontier legions to save them. The legions of three frontier provinces— Britannia , Pannonia Superior , and Syria —resented being excluded from the " donative " and replied by declaring their individual generals to be emperor. Lucius Septimius Severus Geta, the Pannonian commander, bribed the opposing forces, pardoned the Praetorian Guards and installed himself as emperor. He and his successors governed with

18297-443: The granting of rights to draw water for private use from state-funded aqueducts was made an imperial privilege. The provision of free, potable water to the general public became one among many gifts to the people of Rome from their emperor, paid for by him or by the state. In 33 BC, Marcus Agrippa built or subsidised 170 public bath-houses during his aedileship . In Frontinus's time (c. 40–103 AD), around 10% of Rome's aqueduct water

18468-426: The ground surface, with inspection-and-access covers at regular intervals. Conduits above ground level were usually slab-topped. Early conduits were ashlar -built but from around the late Republican era, brick-faced concrete was often used instead. The concrete used for conduit linings was usually waterproof , with a very smooth finish. The flow of water depended on gravity alone. The volume of water transported within

18639-455: The growing season, but was seldom prosecuted as it helped keep food prices low; agriculture was the core of Rome's economy and wealth. Rome's first aqueduct was built in 312 BC, and supplied a water fountain at the city's cattle market. By the 3rd century AD, the city had eleven aqueducts , sustaining a population of over a million in a water-extravagant economy; most of the water supplied the city's many public baths. Cities and towns throughout

18810-521: The health of its inhabitants, were also instrumental in the spread of waterborne diseases. In his De Medicina , the encyclopaedist Celsus warned that public bathing could induce gangrene in unhealed wounds. Frontinus preferred a high rate of overflow in the aqueduct system because it led to greater cleanliness in the water supply, the sewers, and those who used them. The adverse health effects of lead on those who mined and processed it were also well known. Ceramic pipes, unlike lead, left no taint in

18981-477: The imperial dignity. Pertinax, a member of the senate who had been one of Marcus Aurelius's right-hand men, was the choice of Laetus, and he ruled vigorously and judiciously. Laetus soon became jealous and instigated Pertinax's murder by the Praetorian Guard, who then auctioned the empire to the highest bidder, Didius Julianus, for 25,000 sesterces per man. The people of Rome were appalled and appealed to

19152-433: 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

19323-406: The landed elite. This may be connected to Cato's diatribe as censor against the ex-consul Lucius Furius Purpureo : "Look how much he bought the land for, where he is channeling the water!" Cato's attempted reform proved impermanent at best. Though illegal tapping could be punished by seizure of assets, including the illegally watered land and its produce, this law seems never to have been used, and

19494-798: The laws. He died in 161 AD. Marcus Aurelius , known as the Philosopher, was the last of the Five Good Emperors . He was a stoic philosopher and wrote the Meditations . He defeated barbarian tribes in the Marcomannic Wars as well as the Parthian Empire . His co-emperor, Lucius Verus , died in 169 AD, probably from the Antonine Plague , a pandemic that killed nearly five million people through

19665-693: The legions' support. The changes on coinage and military expenditures were the root of the financial crisis that marked the Crisis of the Third Century . Severus was enthroned after invading Rome and having Didius Julianus killed. Severus attempted to revive totalitarianism and, addressing the Roman people and Senate, praised the severity and cruelty of Marius and Sulla, which worried the senators. When Parthia invaded Roman territory, Severus successfully waged war against that country. Notwithstanding this military success, Severus failed in invading Hatra ,

19836-507: The likely legal conflicts arising. In 179 BC the censors used the same legal device to help justify public contracts for several important building projects, including Rome's first stone-built bridge over the Tiber and a new aqueduct to supplement the city's existing – but, by now, inadequate – supply. A wealthy landowner along the aqueduct's planned route, M. Licinius Crassus, refused it passage across his fields, and seems to have forced its abandonment. The construction of Rome's third aqueduct,

20007-418: The local electorate, or by Augustus himself. The entire network relied on just two mountain springs, shared with a river that supported freshwater fish, providing a free food source for all classes. The Augusta supplied eight or nine municipalities or cities and an unknown number of farms and villas, including bathhouses, via branch lines and sub-branch lines; its extremities were the naval port of Misenum and

20178-726: The merchant port of Puteoli . Its delivery is unlikely to have been wholly reliable, adequate or free from dispute. Competition would have been inevitable. Under the emperor Claudius , the City of Rome's contingent of imperial aquarii (aqueduct workers) comprised a familia aquarum of 460, both slave and free, funded through a combination of Imperial largesse and the water fees paid by private subscribers. The familia aquarum comprised "overseers, reservoir‐keepers, line‐walkers, pavers, plasterers, and other workmen" supervised by an Imperial freedman, who held office as procurator aquarium . The curator aquarum had magisterial powers in relation to

20349-423: The mine head. The channels may have deteriorated rapidly, or become redundant as the nearby ore was exhausted. Las Medulas shows at least seven such leats, and Dolaucothi at least five. At Dolaucothi, the miners used holding reservoirs, as well as hushing tanks and sluice gates to control flow, and drop chutes were used for the diversion of water supplies. The remaining traces (see palimpsest ) of such channels allows

20520-405: The more, as thou art greater and stronger.' Here no doubt the underlying notion is not merely symbolical, but in origin the stone is itself the god, an idea which later religion expressed in the cult-title specially used in this connection, Iuppiter Lapis . Ancient Rome In modern historiography , ancient Rome is the Roman civilisation from the founding of the Italian city of Rome in

20691-522: The most impressive surviving examples of a massive masonry multiple-piered conduit, spanned the Gardon river-valley some 48.8 m (160 ft) above the Gardon itself. Where particularly deep or lengthy depressions had to be crossed, inverted siphons could be used, instead of arcades; the conduit fed water into a header tank, which fed it into pipes. The pipes crossed the valley at lower level, supported by

20862-417: The narrowing of apertures, even slight roughening of the aqueduct's ideally smooth-mortared interior surface by travertine deposits could significantly reduce the water's velocity, and thus its rate of flow, by up to 1/4. Accretions within siphons could drastically reduce flow rates through their already narrow diameters, though some had sealed openings that might have been used as rodding eyes , possibly using

21033-411: The next century, based on precursors in neighbouring Campania ; a limited number of private baths and small, street-corner public baths would have had a private water supply, but once aqueduct water was brought to the city's higher elevations, large and well-appointed public baths and fountains were built throughout the city. Public baths and fountains became distinctive features of Roman civilization, and

21204-483: 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

21375-401: The penetration of conduits by tree-roots as particularly damaging. Working patrols would have cleared algal fouling, repaired accidental breaches or accessible shoddy workmanship, cleared the conduits of gravel and other loose debris, and removed accretions of calcium carbonate (also known as travertine ) in systems fed by hard water sources; modern research has found that quite apart from

21546-426: The physical construction. While surveyors could claim ancient right to use land once public, now private, for the good of the State, the land's current possessors could take out a legal counterclaim for compensation based on their long usage, productivity and improvements. They could also join forces with their neighbours to present a united legal front in seeking higher rates of compensation. Aqueduct planning "traversed

21717-709: The populace and the legions. Augustus intended to extend the Roman Empire to the whole known world, and in his reign, Rome conquered Cantabria , Aquitania , Raetia , Dalmatia , Illyricum and Pannonia . Under Augustus' reign, Roman literature grew steadily in what is known as the Golden Age of Latin Literature . Poets like Virgil , Horace , Ovid and Rufus developed a rich literature, and were close friends of Augustus. Along with Maecenas , he sponsored patriotic poems, such as Virgil's epic Aeneid and historiographical works like those of Livy . Augustus continued

21888-608: The populace. Emperors were no longer men linked with nobility; they usually were born in lower-classes of distant parts of the Empire. These men rose to prominence through military ranks, and became emperors through civil wars. Roman aqueducts The Romans constructed aqueducts throughout their Republic and later Empire , to bring water from outside sources into cities and towns. Aqueduct water supplied public baths , latrines , fountains, and private households; it also supported mining operations, milling, farms, and gardens. Aqueducts moved water through gravity alone, along

22059-569: The problems of blockage, blow-outs and venting at their lowest levels, where the pressures were greatest. Nonetheless, siphons were versatile and effective if well-built and well-maintained. A horizontal section of high-pressure siphon tubing in the Aqueduct of the Gier was ramped up on bridgework to clear a navigable river, using nine lead pipes in parallel, cased in concrete. Modern hydraulic engineers use similar techniques to enable sewers and water pipes to cross depressions. At Romano-Gallic Arles,

22230-451: The problems, uses and abuses of Imperial Rome's public water supply. Notable examples of aqueduct architecture include the supporting piers of the Aqueduct of Segovia , and the aqueduct-fed cisterns of Constantinople . "The extraordinary greatness of the Roman Empire manifests itself above all in three things: the aqueducts, the paved roads, and the construction of the drains." Dionysius of Halicarnassus , Roman Antiquities Before

22401-479: The project to a standstill. Eventually, having raised the same objections in 143 and in 140, the decemviri and Senate consented, and 180,000,000 sesterces were allocated for restoration of the two existing aqueducts and completion of the third, in 144–140. The Marcia was named for the praetor Quintus Marcius Rex , who had championed its construction. Springs were by far the most common sources for aqueduct water; most of Rome's supply came from various springs in

22572-496: The public at large, including public baths and fountains. In the Republican era, aqueducts were planned, built and managed under authority of the censors , or if no censor was in office, the aediles . In the Imperial era, lifetime responsibility for water supplies passed to the emperors. Rome had no permanent central body to manage the aqueducts until Augustus created the office of water commissioner ( curator aquarum ); this

22743-400: The regal titles to the newly conquered Eastern territories, war between Octavian and Antony broke out . Octavian annihilated Egyptian forces in the Battle of Actium in 31 BC. Antony and Cleopatra committed suicide . Now Egypt was conquered by the Roman Empire. In 27 BC and at the age of 36, Octavian was the sole Roman leader. In that year, he took the name Augustus . That event

22914-551: The revitalised Persia and also the Germanic peoples , who invaded Gaul. His losses generated dissatisfaction among his soldiers, and some of them murdered him during his Germanic campaign in 235 AD. A disastrous scenario emerged after the death of Alexander Severus : the Roman state was plagued by civil wars, external invasions , political chaos, pandemics and economic depression . The old Roman values had fallen, and Mithraism and Christianity had begun to spread through

23085-405: The rights to a spring and its water from his neighbour, and access rights to a corridor of intervening land, then built an aqueduct of just under 10 kilometres, connecting the springhead to his own villa. Some aqueducts supplied water to industrial sites, usually via an open channel cut into the ground, clay-lined or wood-shuttered to reduce water loss. Most such leats were designed to operate at

23256-493: The sacred stone ( silex ) which was preserved in the temple of Iuppiter on the Capitol, and was brought out to play a prominent part in the ceremony of treaty-making. The fetial , who on that occasion represented the Roman people, at the solemn moment of the oath-taking, struck the sacrificial pig with the silex , saying as he did so, 'Do thou, Diespiter , strike the Roman people as I strike this pig here to-day, and strike them

23427-753: The siege, of whom a majority were Jewish. 97,000 were captured and enslaved , including Simon bar Giora and John of Giscala . Many fled to areas around the Mediterranean. Vespasian was a general under Claudius and Nero and fought as a commander in the First Jewish-Roman War . Following the turmoil of the Year of the Four Emperors , in 69 AD, four emperors were enthroned in turn: Galba , Otho , Vitellius , and, lastly, Vespasian, who crushed Vitellius' forces and became emperor. He reconstructed many buildings which were uncompleted, like

23598-697: The so-called "corn dole" ) and the army. Rather than seek to impose unproductive and probably unenforcable bans, the authorities issued individual water grants and licenses, and regulated water outlets though with variable success. In the 1st century AD, Pliny the Elder , like Cato, could fulminate against grain producers who continued to wax fat on profits from public water and public land. Some landholders avoided such restrictions and entanglements by buying water access rights to distant springs, not necessarily on their own land. A few, of high wealth and status, built their own aqueducts to transport such water from source to field or villa; Mumius Niger Valerius Vegetus bought

23769-497: The son of the deified. In the same year, Octavian and Antony defeated both Caesar's assassins and the leaders of the Liberatores , Marcus Junius Brutus and Gaius Cassius Longinus , in the Battle of Philippi . The Second Triumvirate was marked by the proscriptions of many senators and equites : after a revolt led by Antony's brother Lucius Antonius , more than 300 senators and equites involved were executed, although Lucius

23940-567: The standard, buried conduits, inspection and access points were provided at regular intervals, so that suspected blockages or leaks could be investigated with minimal disruption of the supply. Water lost through multiple, slight leaks in buried conduit walls could be hard to detect except by its fresh taste, unlike that of the natural groundwater. The clear corridors created to protect the fabric of underground and overground conduits were regularly patrolled for unlawful ploughing, planting, roadways and buildings. In De aquaeductu , Frontinus describes

24111-595: The steep gradients that could deliver the high water volumes needed in mining operations. Water was used in hydraulic mining to strip the overburden and expose the ore by hushing , to fracture and wash away metal-bearing rock already heated and weakened by fire-setting , and to power water-wheel driven stamps and trip-hammers that crushed ore for processing. Evidence of such leats and machines has been found at Dolaucothi in south-west Wales . Mining sites, such as Dolaucothi and Las Medulas in north-west Spain , show multiple aqueducts that fed water from local rivers to

24282-520: The succession, and granted to Tiberius the same titles and honours once granted to Augustus: the title of princeps and Pater patriae , and the Civic Crown . However, Tiberius was not an enthusiast for political affairs: after agreement with the Senate, he retired to Capri in 26 AD, and left control of the city of Rome in the hands of the praetorian prefect Sejanus (until 31 AD) and Macro (from 31 to 37 AD). Tiberius died (or

24453-399: The supply to individual destinations, and fresh overflow water could be temporarily stored in cisterns. Aqueducts and their contents were protected by law and custom. The supply to public fountains took priority over the supply to public baths, and both took priority over supplies to wealthier, fee-paying private users. Some of the wealthiest citizens were given the right to a free supply, as

24624-429: 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. Meanwhile, social and economic stresses continued to build; Rome had become a metropolis with a super-rich aristocracy, debt-ridden aspirants, and

24795-485: The supreme deity in Roman religion . He was murdered following a plot within his own household. Following Domitian's murder, the Senate rapidly appointed Nerva as Emperor. Nerva had noble ancestry, and he had served as an advisor to Nero and the Flavians. His rule restored many of the traditional liberties of Rome's upper classes, which Domitian had over-ridden. The Nerva–Antonine dynasty from 96 AD to 192 AD included

24966-434: The system in which water-demand was, for the time being, outstripping supply. The free supply of water to public basins and drinking fountains was officially prioritised over the supply to the public baths, where a very small fee was charged to every bather, on behalf of the Roman people. The supply to basins and baths was in turn prioritised over the requirements of fee-paying private users. The last were registered, along with

25137-448: The temple of the Sun at Emesa, and supposedly illegitimate son of Caracalla, was declared Emperor by the disaffected soldiers of Macrinus. He adopted the name of Antoninus but history has named him after his Sun god Elagabalus , represented on Earth in the form of a large black stone. An incompetent and lascivious ruler, Elagabalus offended all but his favourites. Cassius Dio , Herodian and

25308-464: The tribes of modern-day East Anglia staged a revolt led by queen Boadicea of the Iceni . The rebels sacked and burned Camulodunum , Londinium and Verulamium (modern-day Colchester , London and St Albans respectively) before they were crushed by Paulinus . Boadicea, like Cleopatra before her, committed suicide to avoid the disgrace of being paraded in triumph in Rome. Nero is widely known as

25479-490: The tribes of modern-day Scotland. Hadrian promoted culture, especially the Greek. He forbade torture and humanised the laws. His many building projects included aqueducts, baths, libraries and theatres; additionally, he travelled nearly every province in the Empire to review military and infrastructural conditions. Following Hadrian's death in 138 AD, his successor Antoninus Pius built temples, theatres, and mausoleums, promoted

25650-614: The water rights of other citizens. Inevitably, there would have been rancorous and interminable court cases between neighbours or local governments over competing claims to limited water supplies but on the whole, Roman communities took care to allocate shared water resources according to need. Planners preferred to build public aqueducts on public land ( ager publicus ) , and to follow the shortest, unopposed, most economical route from source to destination. State purchase of privately owned land, or re-routing of planned courses to circumvent resistant or tenanted occupation, could significantly add to

25821-413: The water supply, assisted by a team of architects, public servants, notaries and scribes, and heralds; when working outside the city, he was further entitled to two lictors to enforce his authority. Substantial fines could be imposed for even single offences against the laws relating to aqueducts: for example, 10,000 sesterces for allowing a tree to damage the conduit, and 100,000 sesterces for polluting

25992-621: The water they carried, and were therefore preferred over lead for drinking water. In some parts of the Roman world, particularly in relatively isolated communities with localised water systems and limited availability of other, more costly materials, wooden pipes were commonly used; Pliny recommends water-pipes of pine and alder as particularly durable, when kept wet and buried. Examples revealed through archaeology include pipes of alder, clamped at their joints with oak, at Vindolanda fort and pipes of alder in Germany. Where lead pipes were used,

26163-429: The water within the conduit, or allowing one's slave to do the same. Rome's first aqueduct (312 BC) discharged at very low pressure and at a more-or-less constant rate in the city's main trading centre and cattle-market , probably into a low-level, cascaded series of troughs or basins; the upper for household use, the lower for watering the livestock traded there. Most Romans would have filled buckets and storage jars at

26334-424: The water's orientation from an existing northerly watershed to a southerly watershed, establishing the new gradient using a 6 km tunnel, several shorter tunnels, and arcades, one of which was supported more or less at sea level by foundations on the sea bed at Misenum. En route , it supplied several cities and many villas, using branch lines. Roman aqueducts required a comprehensive system of regular maintenance. On

26505-575: 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

26676-657: Was Josephus' sponsor and Pliny dedicated his Naturalis Historia to Titus, son of Vespasian. Vespasian sent legions to defend the eastern frontier in Cappadocia , extended the occupation in Britannia (modern-day England, Wales and southern Scotland ) and reformed the tax system. He died in 79 AD. Titus became emperor in 79. He finished the Flavian Amphitheater, using war spoils from the First Jewish-Roman War, and hosted victory games that lasted for

26847-555: Was a high status, high-profile Imperial appointment. In 97 AD, Frontinus, who had already had a distinguished career as consul, general and provincial governor, served both as consul and as curator aquarum , under the emperor Nerva . Particular sections of Campania's very long, complex, costly and politically sensitive Aqua Augusta , constructed in the early days of the Augustan principate were supervised by wealthy, influential, local curatores . They were drawn from local elites by

27018-476: 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

27189-506: 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

27360-445: Was involved in some form of agricultural work. Water was possibly the most important variable in the agricultural economy of the Mediterranean world. Roman Italy's natural fresh-water sources – springs, streams, rivers and lakes – were abundant in some places, entirely absent in others. Rainfall was unpredictable. Water tended to be scarce when most needed during the warm, dry summer growing season. Farmers whose villas or estates were near

27531-497: Was killed) in 37 AD. The male line of the Julio-Claudians was limited to Tiberius' nephew Claudius , his grandson Tiberius Gemellus and his grand-nephew Caligula . As Gemellus was still a child, Caligula was chosen to rule the empire. He was a popular leader in the first half of his reign, but became a crude and insane tyrant in his years controlling government. The Praetorian Guard murdered Caligula four years after

27702-524: Was lowest, during the winter months. The piped water supply could be selectively reduced or shut off at the castella when small or local repairs were needed, but substantial maintenance and repairs to the aqueduct conduit itself required the complete diversion of water at any point upstream, including the spring-head itself. Frontinus describes the use of temporary leaden conduits to carry the water past damaged stretches while repairs were made, with minimal loss of supply. The Aqua Claudia , most ambitious of

27873-426: Was measured in quinaria (cross-sectional area of the pipe) at the point of supply and no formula or physical device was employed to account for variations in velocity, rate of flow or actual usage. Brun, 1991, used lead pipe stamps to calculate a plausible water distribution as a percentage of the whole; 17% went to the emperor (including his gifts, grants and awards); 38% went to private individuals; and 45% went to

28044-532: Was militarily passive. Cassius Dio identifies his reign as the beginning of Roman decadence : "(Rome has transformed) from a kingdom of gold to one of iron and rust." Commodus was killed by a conspiracy involving Quintus Aemilius Laetus and his wife Marcia in late 192 AD. The following year is known as the Year of the Five Emperors , during which Helvius Pertinax , Didius Julianus , Pescennius Niger , Clodius Albinus and Septimius Severus held

28215-500: Was more than twice that of the Aqua Appia, and supplied water to higher elevations of the city. By 145 BC, the city had again outgrown its combined supplies. An official commission found the aqueduct conduits decayed, their water depleted by leakage and illegal tapping. The praetor Quintus Marcius Rex restored them, and introduced a third, "more wholesome" supply, the Aqua Marcia , Rome's longest aqueduct and high enough to supply

28386-570: Was no chance of a return to the Roman Republic , and so a new emperor had to arise. After the turmoil in the Year of the Four Emperors , Titus Flavius Vespasianus (anglicised as Vespasian) took control of the empire and established a new dynasty. Under the Flavians, Rome continued its expansion, and the state remained secure. Under Trajan, the Roman Empire reached the peak of its territorial expansion. Rome's dominion now spanned 5.0 million square kilometres (1.9 million square miles). The most significant military campaign undertaken during

28557-554: Was now pre-eminent over Rome: in five years he held four consulships, two ordinary dictatorships, and two special dictatorships, one for perpetuity. He was murdered in 44 BC, on the Ides of March by the Liberatores . Caesar's assassination caused political and social turmoil in Rome; the city was ruled by his friend and colleague, Marcus Antonius . Soon afterward, Octavius , whom Caesar adopted through his will, arrived in Rome. Octavian (historians regard Octavius as Octavian due to

28728-403: Was probably impracticable; while water thefts profited farmers, they could also create food surpluses and keep food prices low. Grain shortages in particular could lead to famine and social unrest. Any practical solution must strike a balance between the water-needs of urban populations and grain producers, tax the latter's profits, and secure sufficient grain at reasonable cost for the Roman poor (

28899-557: Was spared. The Triumvirate divided the Empire among the triumvirs: Lepidus was given charge of Africa , Antony, the eastern provinces, and Octavian remained in Italia and controlled Hispania and Gaul . The Second Triumvirate expired in 38 BC but was renewed for five more years. However, the relationship between Octavian and Antony had deteriorated, and Lepidus was forced to retire in 36 BC after betraying Octavian in Sicily . By

29070-482: Was succeeded by the general Trajan . Trajan is credited with the restoration of traditional privileges and rights of commoner and senatorial classes, which later Roman historians claim to have been eroded during Domitian's autocracy. Trajan fought three Dacian wars , winning territories roughly equivalent to modern-day Romania and Moldova . He undertook an ambitious public building program in Rome, including Trajan's Forum , Trajan's Market and Trajan's Column , with

29241-427: Was used to supply 591 public fountains, among which were 39 lavishly decorative fountains that Frontinus calls munera . According to one of several much later regionaries, by the end of the 4th century AD, Rome's aqueducts within the City – 19 of them, according to the regionary – fed 11 large public baths, 965 smaller public bathhouses and 1,352 public fountains. Between 65 and 90% of the Roman Empire's population
