111-610: There are the remains of at least one Roman bridge along the road, which is the Ponte presso Tor di Valle. Modern Via Ostiense follows a similar path to the old road, forming the main connection of Rome to Ostia (one of the quarters of Rome at present) together with the Via del Mare. On its way to Ostia, the road passes by the important basilica of Saint Paul Outside the Walls . This article about an Ancient Roman building or structure

222-504: A series of speeches portraying him as a threat to the republican order. With opinion in Rome turning against him and his year of consular power nearing its end, Antony attempted to pass laws that would assign him the province of Cisalpine Gaul . Octavian meanwhile built up a private army in Italy by recruiting Caesarian veterans, and on 28 November he won over two of Antony's legions with

333-607: A standing army , established the Praetorian Guard as well as official police and fire-fighting services for Rome, and rebuilt much of the city during his reign. Augustus died in AD 14 at age 75, probably from natural causes. Persistent rumors, substantiated somewhat by deaths in the imperial family, have claimed his wife Livia poisoned him. He was succeeded as emperor by his adopted son Tiberius , Livia's son and former husband of Augustus's only biological child, Julia . As

444-677: A battle against the Sabines the Romans set one of their wooden bridges on fire, driving the enemy back. Other early wooden bridges used post and lintel construction. Pontoon bridges were built by laying boats from side to side across a river. During Julius Caesar 's campaign in Germany , he built bridges by driving wooden piles into the stream bed from floating platforms and fixing beams at right angles across them to create trestles. Trajan built another bridge supported by stone during

555-399: A bonus of 500 denarii . Arriving in Rome on 6 May 44 BC, Octavian found consul Mark Antony, Caesar's former colleague, in an uneasy truce with the dictator's assassins. They had been granted a general amnesty on 17 March, yet Antony had succeeded in driving most of them out of Rome with an inflammatory eulogy at Caesar's funeral, mounting public opinion against the assassins. Mark Antony

666-456: A consequence of Roman customs , society, and personal preference, Augustus ( / ɔː ˈ ɡ ʌ s t ə s / aw- GUST -əs ) was known by many names throughout his life: He was born in Rome on 23 September 63 BC. His paternal family was from the Volscian town of Velletri , approximately 40 kilometres (25 mi) south-east of the city. He was born at Ox Head, a small property on

777-498: A coward for handing over his direct military control to Marcus Vipsanius Agrippa instead. After Philippi, a new territorial arrangement was made among the members of the Second Triumvirate. Gaul and the province of Hispania were placed in the hands of Octavian. Antony traveled east to Egypt where he allied himself with Queen Cleopatra , the former lover of Julius Caesar and mother of Caesar's son Caesarion . Lepidus

888-558: A date that he would later commemorate as the beginning of his public career. Antony's forces were defeated at the battles of Forum Gallorum (14 April) and Mutina (21 April), forcing Antony to retreat to Transalpine Gaul . Both consuls were killed, however, leaving Octavian in sole command of their armies. These victories earned him his first acclamation as imperator , a title reserved for victorious commanders. The Senate heaped many more rewards on Decimus Brutus than on Octavian for defeating Antony, then attempted to give command of

999-456: A flat downstream face, though some bridges, such as a bridge in Chester , are exceptions. Two niches carrying cornices were inserted between pilasters . They were then put above the framed starlings. Roman bridges had spandrels , between which images of dolphins were often inserted. They rarely had wide spans and thick piers with bow -shaped piers that used small openings to allow for

1110-448: A foundation. At first, they used heavy timbers as deep foundations in the riverbed, but a later technique involved using watertight walls to redirect the water and then laying a stone foundation in the area. To aid in the construction of a foundation, work was exclusively done during the dry season . This ensured as many piers as possible were accessible. There is some evidence that in order to construct bridges rivers were diverted. Such

1221-571: A monopoly on political and martial power. The Senate still controlled North Africa, an important regional producer of grain , as well as Illyria and Macedonia , two strategic regions with several legions. However, the Senate had control of only five or six legions distributed among three senatorial proconsuls, compared to the twenty legions under the control of Octavian, and their control of these regions did not amount to any political or military challenge to Octavian. The Senate's control over some of

1332-429: A new family usually retained their old nomen in cognomen form (e.g., Octavianus for one who had been an Octavius, Aemilianus for one who had been an Aemilius, etc. see Roman naming conventions for adoptions ). However, though some of his contemporaries did, there is no evidence that Octavian officially used the name Octavianus , as it would have made his adoptive origins too obvious. Historians usually refer to

1443-1001: A new will with the Vestal Virgins , naming Octavian as the prime beneficiary. Octavian was studying and undergoing military training in Apollonia , Illyria , when Julius Caesar was assassinated on the Ides of March (15 March) 44 BC. He rejected the advice of some army officers to take refuge with the troops in Macedonia and sailed to Italy to ascertain whether he had any potential political fortunes or security. Caesar had no living legitimate children under Roman law and so had adopted Octavian, his grand-nephew, in his will, making him his primary heir. Mark Antony later charged that Octavian had earned his adoption by Caesar through sexual favours, though Suetonius describes Antony's accusation as political slander . This form of slander

1554-542: A political and martial gamble in opposing Octavian however, since the Roman army still depended on the triumvirs for their salaries. Lucius and his allies ended up in a defensive siege at Perusia , where Octavian forced them into surrender in early 40 BC. Lucius and his army were spared because of his kinship with Antony, the strongman of the East, while Fulvia was exiled to Sicyon . Octavian showed no mercy, however, for

1665-420: A practice might have been performed by Trajan when constructing his Danube bridge. Roman engineers might have diverted rivers using rudimentary methods and tools. Sometimes dirt was added to the foundation. The foundation of a bridge could either be built above or below water level . Building the bridge above water level resulted in a need for a wider span. Bridge's tunnels and spandrels were designed to decrease

1776-531: A reconstruction during the reign of Augustus (27 BC – 14 AD). The Pons Fabricius, built in 62 BC during the late Republic, is the oldest Roman bridge that is still intact and in use. The largest Roman bridge was Trajan's Bridge over the lower Danube , constructed by Apollodorus of Damascus , which remained for over a millennium the longest bridge to have been built both in terms of overall and span length. Roman engineers built stone arch or stone pillar bridges over all major rivers of their Imperium , save two:

1887-543: A renegade general, following Julius Caesar's victory over his father, had established himself in Sicily and Sardinia as part of an agreement reached with the Second Triumvirate in 39 BC. Both Antony and Octavian were vying for an alliance with Pompeius. Octavian succeeded in a temporary alliance in 40 BC when he married Scribonia , a sister (or daughter) of Pompeius's father-in-law Lucius Scribonius Libo . Scribonia gave birth to Octavian's only natural child, Julia ,

1998-680: A result, he inherited Caesar's name, estate, and the loyalty of his legions. He, Mark Antony , and Marcus Lepidus formed the Second Triumvirate to defeat the assassins of Caesar. Following their victory at the Battle of Philippi (42 BC), the Triumvirate divided the Roman Republic among themselves and ruled as de facto dictators . The Triumvirate was eventually torn apart by the competing ambitions of its members; Lepidus

2109-412: A second founding of Rome. The title of Romulus was associated too strongly with notions of monarchy and kingship, an image that Octavian tried to avoid. The Senate also confirmed his position as princeps senatus , which originally meant the member of the Senate with the highest precedence, but in this case it became an almost regnal title for a leader who was first in charge. The honorific augustus

2220-551: A show of returning full power to the Roman Senate and relinquishing his control of the Roman provinces and their armies. Under his consulship, however, the Senate had little power in initiating legislation by introducing bills for senatorial debate. Octavian was no longer in direct control of the provinces and their armies, but he retained the loyalty of active duty soldiers and veterans alike. The careers of many clients and adherents depended on his patronage, as his financial power

2331-533: A span of 1.3 metres (4 ft 3 in). Another bridge over the Bibey River in Galicia has a pier 1 metre (3 ft 3 in) wide, arches with a 4.3-metre (14 ft) span, 6-and-9-metre (20 and 30 ft) side arches, and an arch spanning 18.5 metres (61 ft). Wider spans increase the bridge's drainage, reduce water pressure on the spandrels , and reduced the bridge's weight. Trajan's Bridge over

2442-569: A tenth of those promised, which Antony viewed as an intentional provocation. Octavian and Lepidus launched a joint operation against Sextus in Sicily in 36 BC. Despite setbacks for Octavian, the naval fleet of Sextus Pompeius was almost entirely destroyed on 3 September by General Agrippa at the naval battle of Naulochus . Sextus fled to the east with his remaining forces, where he was captured and executed in Miletus by one of Antony's generals

Roman bridge The ancient Romans were the first civilization to build large, permanent bridges . Early Roman bridges used techniques introduced by Etruscan immigrants , but the Romans improved those skills, developing and enhancing methods such as arches and keystones . There were three major types of Roman bridge : wooden, pontoon, and stone. Early Roman bridges were wooden, but by

2664-473: Is from the Latin word augere (meaning "to increase") and can be translated as "illustrious one" or "sublime". It was a title of religious authority rather than political one, and it indicated that Octavian now approached divinity. His name of Augustus was also more favorable than Romulus , the previous one which he styled for himself in reference to the story of the legendary founder of Rome , which symbolized

2775-619: Is less than a semicircle. The Romans built both single spans and lengthy multiple-arch aqueducts , such as the Pont du Gard and Segovia Aqueduct . Their bridges often had flood openings in the piers, e.g. in the Pons Fabricius in Rome (62 BC), one of the world's oldest major bridges still standing. There were two main types of wooden bridge in Britain. Small timber bridges with girders , and large ones made of stone and wood. Throughout

2886-417: The aerarium Saturni , the public treasury. According to historian H. H. Scullard , however, Octavian's power was based on the exercise of "a predominant military power and ... the ultimate sanction of his authority was force, however much the fact was disguised." The Senate proposed to Octavian, the victor of Rome's civil wars, that he once again assume command of the provinces. The Senate's proposal

2997-557: The Dacian Wars . Roman engineers gradually developed new techniques to build bridges, such as oval-shaped bases and pierced bases to facilitate the movement of water. Many bridges would have marble reliefs or carvings , but these bridges were likely used exclusively by government officials because of the difficulty and expense of carving marble artwork. There were three major types of Roman bridges. These were wooden, pontoon, and stone bridges. A list of Roman bridges compiled by

3108-477: The Danube featured open-spandrel segmental arches made of wood (standing on 40 metres (130 ft) high concrete piers). This was to be the longest arch bridge for a thousand years both in terms of overall and individual span length. The longest extant Roman bridge is the 790-metre (2,590 ft) Puente Romano at Mérida . When building bridges across moving bodies of water, Roman engineers would begin by laying

3219-739: The Euphrates , which lay at the frontier to the rival Persian empires , and the Nile , the longest river in the world, which was 'bridged' as late as 1902 by the British Old Aswan Dam . The largest rivers to be spanned by solid bridges by the Romans were the Danube and the Rhine , the two largest European rivers west of the Eurasian Steppe . The lower Danube was crossed by least two ( Trajan's Bridge , Constantine's Bridge ) and

In his childhood, he received the cognomen "Thurinus", possibly commemorating his father's victory at Thurii over a rebellious band of slaves which occurred a few years after his birth. Suetonius wrote: "There are many indications that the Octavian family was in days of old a distinguished one at Velitrae; for not only was a street in

3441-478: The Peloponnese , and ensured him a future position as consul for 35 BC. The territorial agreement between the triumvirate and Sextus Pompeius began to crumble once Octavian divorced Scribonia and married Livia on 17 January 38 BC. One of Pompeius's naval commanders betrayed him and handed over Corsica and Sardinia to Octavian. Octavian lacked the resources to confront Pompeius alone, so an agreement

3552-531: The Pons Fabricius , and even after the Fall of the Western Roman Empire , engineers copied their bridges. Roman bridge-building techniques persisted until the 18th century: for example, the prevalence of arches in bridges can be attributed to the Romans. Roman bridges were much larger than the bridges of other civilizations. They could be anywhere from 4.6 to 18.3 metres (15 to 60 ft) long. By

A similar ambiguity is seen in his chosen names, the implied rejection of monarchical titles whereby he called himself Princeps Civitatis ('First Citizen') juxtaposed with his adoption of the title Augustus . Augustus dramatically enlarged

3774-473: The 2nd century BC stone was being used. Stone bridges used the arch as their basic structure , and most used concrete , the first use of this material in bridge-building. Following the conquests of Tarquinius Priscus , Etruscan engineers migrated to Rome, bringing with them their knowledge of bridge-building techniques. The oldest bridge in ancient Rome was the Pons Sublicius . It was built in

3885-404: The 2nd century BC, the Romans had further refined their bridge-building techniques, using stronger materials such as volcanic ash , lime and gypsum . Also, they began to use iron clamps to hold together bridges, constructing midstream arches, and pentagonal stones to allow for wider vaults . According to Canadian classicist John Peter Oleson , no known stone bridges existed in Italy before

3996-527: The 2nd century BC. This view is not supported unanimously: Spanish engineer Leonardo Fernández Troyano suggested that stone bridges have existed since Pre-Roman Italy . Between 150 and 50 BC, many stone Roman bridges were built, the Pons Aemilius being the first. Engineers began to use stone instead of wood to exemplify the Pax Romana and to construct longer-lasting bridges. These were

4107-498: The 6th century BC by Ancus Marcius over the Tiber River . The Romans improved on Etruscan architectural techniques. They developed the voussoir , stronger keystones , vaults , and superior arched bridges. Roman arched bridges were capable of withstanding more stress by dispersing forces across bridges. Many Roman bridges had semicircular arches, but a few were segmental , i.e. with an arc of less than 180 degrees. By

4218-450: The East, Octavian in the West. The Italian Peninsula was left open to all for the recruitment of soldiers, but in reality this provision was useless for Antony in the East. To further cement relations of alliance with Antony, Octavian gave his sister, Octavia Minor , in marriage to Antony in late 40 BC. Sextus Pompeius threatened Octavian in Italy by denying shipments of grain through

4329-511: The Great and was elected consul in 56 BC. Philippus never had much of an interest in young Octavian. Because of this, Octavian was raised by his grandmother, Julia , the sister of Julius Caesar. Julia died in 52 or 51 BC, and Octavian delivered the funeral oration for his grandmother. From this point, his mother and stepfather took a more active role in raising him. He donned the toga virilis ("toga of manhood") four years later and

Pompeius's control over the sea prompted him to take on the name Neptuni filius , "son of Neptune ". A temporary peace agreement was reached in 39 BC with the Pact of Misenum ; the blockade on Italy was lifted once Octavian granted Pompeius Sardinia, Corsica , Sicily, and

These bridges were supported by wooden trestles spanned by horizontal timbers and reinforced with struts , and they were possibly cantilevered . In order to simplify the process of cutting trees, multiple shorter timbers were used. Wooden poles were driven into

4662-491: The Roman generals, and even if he desired no position of authority his position demanded that he look to the well-being of the city of Rome and the Roman provinces . Octavian's aims from this point forward were to return Rome to a state of stability, traditional legality, and civility by lifting the overt political pressure imposed on the courts of law and ensuring free elections—in name at least. On 13 January 27 BC, Octavian made

4773-440: The Roman provinces helped maintain a republican facade for the autocratic principate. Also, Octavian's control of entire provinces followed republican-era precedents for the objective of securing peace and creating stability, in which such prominent Romans as Pompey had been granted similar military powers in times of crisis and instability. On 16 January 27 BC the Senate gave Octavian the new title of augustus . Augustus

4884-573: The Roman world was largely free of armed conflict. The Principate system of government was established during his reign and lasted until the Crisis of the Third Century . Octavian was born into an equestrian branch of the plebeian gens Octavia . His maternal great-uncle Julius Caesar was assassinated in 44 BC , and Octavian was named in Caesar's will as his adopted son and heir; as

4995-473: The Senate and the people while upholding the republican traditions of Rome, appearing that he was not aspiring to dictatorship or monarchy. Marching into Rome, Octavian and Agrippa were elected as consuls by the Senate. Years of civil war had left Rome in a state of near lawlessness, but the republic was not prepared to accept the control of Octavian as a despot. At the same time, Octavian could not give up his authority without risking further civil wars among

5106-467: The Senate grant him, his wife, and his sister tribunal immunity , or sacrosanctitas , in order to ensure his own safety and that of Livia and Octavia once he returned to Rome. Meanwhile, Antony's campaign turned disastrous against Parthia, tarnishing his image as a leader, and the mere 2,000 legionaries sent by Octavian to Antony were hardly enough to replenish his forces. On the other hand, Cleopatra could restore his army to full strength; he already

5217-597: The Senate officially revoked Antony's powers as consul and declared war on Cleopatra's regime in Egypt. In early 31 BC, Antony and Cleopatra were temporarily stationed in Greece when Octavian gained a preliminary victory: the navy successfully ferried troops across the Adriatic Sea under the command of Agrippa. Agrippa cut off Antony and Cleopatra's main force from their supply routes at sea, while Octavian landed on

5328-759: The Senate's archenemy Mark Antony. Octavian made another bold move in 44 BC when, without official permission, he appropriated the annual tribute that had been sent from Rome's Near Eastern province to Italy. Octavian began to bolster his personal forces with Caesar's veteran legionaries and with troops designated for the Parthian war, gathering support by emphasizing his status as heir to Caesar. On his march to Rome through Italy, Octavian's presence and newly acquired funds attracted many, winning over Caesar's former veterans stationed in Campania . By June, he had gathered an army of 3,000 loyal veterans, paying each

5439-568: The armies of Brutus and Cassius, who had built their base of power in Greece. After two battles at Philippi in Macedonia in October 42, the Caesarian army was victorious and Brutus and Cassius committed suicide. Mark Antony later used the examples of these battles as a means to belittle Octavian, as both battles were decisively won with the use of Antony's forces. In addition to claiming responsibility for both victories, Antony branded Octavian as

The Roman dominions were divided between Octavian in the West and Antony in the East. Octavian ensured Rome's citizens of their rights to property in order to maintain peace and stability in his portion of the empire. This time, he settled his discharged soldiers outside of Italy, while also returning 30,000 slaves to their former Roman owners—slaves who had fled to join Pompeius's army and navy. Octavian had

5661-499: The concrete. Travertine limestone and tuff were used to build Roman bridges, or they could be made of dry rubble or concrete. Often the building materials varied in smoothness , or rustication . Other bridges were made of bossed limestone combined with cornices, voussoirs and slabs. Sometimes bedrock , buttresses , and vaults were used to construct bridges. Bridges built in Iberia tended to have cylindrical vault geometry. In

5772-555: The consular legions to Decimus Brutus. In response, Octavian stayed in the Po Valley and refused to aid any further offensive against Antony. In July, an embassy of centurions sent by Octavian entered Rome and demanded the consulship left vacant by Hirtius and Pansa and also that the decree should be rescinded which declared Antony a public enemy. When this was refused, he marched on the city with eight legions. He encountered no military opposition in Rome and on 19 August 43 BC

5883-455: The earliest surviving bridge featuring a pointed arch, though it is now submerged by the Keban Dam . Roman arches were unable to properly fit into the arch springings, forcing the base of the arches upwards. In the 2nd century, arches become thinner, and spandrels became flat and pierced with holes. They were constructed using a wooden frame to hold wedge-shaped blocks in place. Afterwards

5994-471: The empire for opus pontis . The Anglo-Saxons continued this practice with bricg-geworc , a literal translation of opus pontis . Built in 142 BC, the Pons Aemilius , later named Ponte Rotto (broken bridge), is the oldest Roman stone bridge in Rome , with only one surviving arch and pier. However, evidence suggests only the abutment is original to the 2nd century BC while the arch and pier perhaps date to

He reformed the Roman system of taxation, developed networks of roads with an official courier system , established

A more complete survey by the Italian scholar Vittorio Galliazzo found 931 Roman bridges, mostly of stone, in as many as 26 different countries (including former Yugoslavia ; see right table). A segmental arch is an arch that

6327-438: The enticing offer of monetary gain. In the face of Octavian's large and capable force, Antony saw the danger of staying in Rome and, to the relief of the Senate, he left Rome for Cisalpine Gaul, which was to be handed to him on 1 January. However, the province had earlier been assigned to Decimus Junius Brutus Albinus , one of Caesar's assassins, who now refused to yield to Antony. Antony besieged him at Mutina and rejected

6438-541: The exception of Antony's older son . Octavian had previously shown little mercy to surrendered enemies and acted in ways that had proven unpopular with the Roman people, yet he was given credit for pardoning many of his opponents after the Battle of Actium. After Actium and the defeat of Antony and Cleopatra, Octavian was in a position to rule the entire republic under an unofficial principate —but he had to achieve this through incremental power gains. He did so by courting

6549-486: The first half of the 2nd century BC, blocks of stone held together with iron clamps were used to aid in the construction of bridges. Although Roman bricks were used to build many bridges, they were far more commonly used to build aqueducts. Bridges built from bricks were rare as bricks often failed to survive erosion . The brick bridges that were built were generally used by the military , and they used construction techniques called opus vittatum and opus mixtum ,

6660-458: The first large-scale bridges ever constructed. Bridges were constructed by the Roman government to serve the needs of the military and the empire's administration. Sometimes roads and bridges were used for commercial purposes, but this was rare as boats better served the needs of the Roman economy . By the 2nd century Roman techniques had declined, and they had been mostly lost by the 4th century. Some Roman bridges are still used today, such as

6771-418: The flow of water. During construction, cranes were used to move materials and lift heavy objects. Some bridges had aprons . They were used to surround piers. Usually, the aprons covered the area of the stream bed near the bridge. Agrippa used ashlar and bricks to cover the outside of bridges and concrete for footings and water channels. Ashlar was used because large amounts of wood was needed to cast

The breach between Antony and Octavian prompted a large portion of the senators, as well as both of that year's consuls, to leave Rome and defect to Antony. However, Octavian received two key deserters from Antony in the autumn of 32 BC: Munatius Plancus and Marcus Titius. These defectors gave Octavian

Lepidus surrendered to Octavian and was permitted to retain the office of pontifex maximus (head of

After coming ashore with a handful of companions, he crossed hostile territory to Caesar's camp, which impressed Caesar considerably. Velleius Paterculus reports that after that time, Caesar allowed the young man to share his carriage. When back in Rome, Caesar deposited

7215-408: The foundation of his political actions. To a large extent, the public was aware of the vast financial resources that Octavian commanded. He failed to encourage enough senators to finance the building and maintenance of networks of roads in Italy in 20 BC, but he undertook direct responsibility for them. This was publicized on the Roman currency issued in 16 BC, after he donated vast amounts of money to

7326-528: The foundation of the bridge would be put in this area. Cofferdams were constructed of many piles held together. It is possible the piles were interconnected, likely to improve positioning, waterproofness , or both. Cofferdams would have been sealed with packed clay. The cofferdams also needed to be consistently dry. In order to achieve this, engineers would use tools such as buckets to drain the water. Wooden bridges could be burned to stop an attacker, or dismantled quickly. For example, according to Livy , during

Other early techniques used to build wooden bridges involved barges , sometimes they were moored side by side. Workmen would raise weights, sometimes by rope, then it would fall down onto the piles.

Because this technique created cofferdams , which are enclosures build to pump water out of an area. The base for

Octavian forcibly entered the temple of the Vestal Virgins and seized Antony's secret will, which he promptly publicized. The will would have given away Roman-conquered territories as kingdoms for his sons to rule and designated Alexandria as the site for a tomb for him and his queen. In late 32 BC,

One brick bridge in Ticino , Switzerland , has stone arches and brick spandrels. Bricks were sometimes used to create parts of bridges, such as vaults , piers with welding joints , and brick and mortar rubble . Early Roman bridges were wooden, including one constructed by Apollodorus and

7881-559: The legions under their command followed suit. Meanwhile, in Sicyon, Antony's wife Fulvia died of a sudden illness while Antony was en route to meet her. Fulvia's death and the mutiny of their centurions allowed the two remaining triumvirs to effect a reconciliation. In the autumn of 40, Octavian and Antony approved the Treaty of Brundisium, by which Lepidus would remain in Africa, Antony in

While Octavian acted as consul in Rome, he dispatched senators to the provinces under his command as his representatives to manage provincial affairs and ensure that his orders were carried out. The provinces not under Octavian's control were overseen by governors chosen by the Roman Senate. Octavian became the most powerful political figure in the city of Rome and in most of its provinces, but he did not have

8214-409: The mass of allies loyal to Lucius. On 15 March, the anniversary of Julius Caesar's assassination, he had 300 Roman senators and equestrians executed for allying with Lucius. Perusia also was pillaged and burned as a warning for others. This bloody event sullied Octavian's reputation and was criticized by many, such as Augustan poet Sextus Propertius . Sextus Pompeius , the son of Pompey and still

8325-493: The middle and lower Rhine by four different bridges (the Roman Bridge at Mainz , Caesar's Rhine bridges , the Roman Bridge at Koblenz , the Roman Bridge at Cologne ). For rivers with strong currents and to allow swift army movements, pontoon bridges were also routinely employed. Judging by the distinct lack of records of pre-modern solid bridges spanning larger rivers, the Roman feat appears to be unsurpassed anywhere in

8436-428: The most frequented part of town long ago called Octavius, but an altar was shown there besides, consecrated by an Octavius. This man was leader in a war with a neighbouring town ..." Due to the crowded nature of Rome at the time, Octavian was taken to his father's home village at Velletri to be raised. Octavian mentions his father's equestrian family only briefly in his memoirs. His paternal great-grandfather Octavius

8547-508: The much larger fleet of smaller, more maneuverable ships under commanders Agrippa and Gaius Sosius in the Battle of Actium on 2 September 31 BC. Antony and his remaining forces were spared by a last-ditch effort from Cleopatra's fleet that had been waiting nearby. A year later, Octavian defeated their forces in Alexandria on 1 August 30 BC—after which Antony and Cleopatra committed suicide . Antony fell on his own sword and

8658-403: The new Caesar as "Octavian" during the time between his adoption and his assumption of the name Augustus in 27 BC in order to avoid confusing the dead dictator with his heir. Octavian could not rely on his limited funds to make a successful entry into the upper echelons of the Roman political hierarchy. After a warm welcome by Caesar's soldiers at Brundisium, Octavian demanded a portion of

8769-521: The proscription of his ally Cicero, Antony the proscription of his maternal uncle Lucius Julius Caesar (the consul of 64 BC), and Lepidus his brother Paullus . On 1 January 42 BC, the Senate posthumously recognized Julius Caesar as a divinity of the Roman state, divus Iulius . Octavian was able to further his cause by emphasizing the fact that he was divi filius , "Son of the Divine". Antony and Octavian then sent twenty-eight legions by sea to face

8880-415: The resolutions passed by the Senate to stop the fighting. The Senate had no army to enforce their resolutions. This provided an opportunity for Octavian, who already was known to have armed forces. Cicero also defended Octavian against Antony's taunts about Octavian's lack of noble lineage and aping of Julius Caesar's name, stating "we have no more brilliant example of traditional piety among our youth." At

8991-516: The responsibility of multiple local municipalities. Their shared costs prove Roman bridges belonged to the region overall, and not to any one town (or two, if on a border). The Alcántara Bridge in Lusitania , for example, was built at the expense of 12 local municipalities, whose names were added on an inscription. Later, in the Roman Empire , the local lords of the land had to pay tithes to

9102-585: The rest of the Roman world, except for northern Europe, arched bridges made of stone were common. This was likely due to the climate and rivers of the regions. Rivers were much calmer and water levels were lower in the southern parts of the Empire. This ensured foundations were easy to construct. While in the northern parts it was much harder to lay down foundations due to the high water level, muddy water, and substantial waterflow. The costs of building and repairing bridges, known as opus pontis ("bridge work"), were

9213-595: The same day that he divorced her to marry Livia Drusilla , little more than a year after their marriage. While in Egypt, Antony had been engaged in an affair with Cleopatra and had fathered three children with her. Aware of his deteriorating relationship with Octavian, Antony left Cleopatra; he sailed to Italy in 40 BC with a large force to oppose Octavian, laying siege to Brundisium . This new conflict proved untenable for both Octavian and Antony, however. Their centurions, who had become important figures politically, refused to fight because of their Caesarian cause, while

9324-458: The same. Antony refused. Roman troops captured the Kingdom of Armenia in 34 BC, and Antony made his son Alexander Helios the ruler of Armenia. He also awarded the title " Queen of Kings " to Cleopatra, acts that Octavian used to convince the Roman Senate that Antony had ambitions to diminish the preeminence of Rome. Octavian became consul once again on 1 January 33 BC, and he opened

9435-483: The summer, Octavian won the support of Caesarian veterans and also made common cause with those senators—many of whom were themselves former Caesarians—who perceived Antony as a threat to the state. After an abortive attempt by the veterans to reconcile Octavian and Antony, Antony's bellicose edicts against Brutus and Cassius alienated him from the moderate Caesarians in the Senate, who feared a renewed civil war. In September, Marcus Tullius Cicero began to attack Antony in

9546-473: The time of Augustus around the turn of the 1st millennium the maximum span of Roman bridges increased from around 24 metres (79 ft) in 142 BC to 35 metres (115 ft). The Ponte Sant'Angelo , built during the reign of Hadrian , has five arches each with a span of 18 metres (59 ft). A bridge in Alcántara has piers 1 metre (3 ft 3 in) wide, 47 metres (154 ft) high, and arches with

9657-416: The urging of Cicero, the Senate inducted Octavian as senator on 1 January 43 BC, yet he also was given the power to vote alongside the former consuls. In addition, Octavian was granted imperium pro praetore (commanding power) which legalized his command of troops, sending him to relieve the siege along with Hirtius and Pansa (the consuls for 43 BC). He assumed the fasces on 7 January,

9768-409: The use of pointed arches . Roman piers were thick enough to support the pressure of an arch. Stone arches allowed bridges to have much longer spans. Usually, iron clamps covered in lead were used to build piers. Because of poor performance underwater, Roman piers were often destroyed over time. Bridges that survived to the modern day were often furnished with cut waters on the upstream side and

9879-790: The weight of the bridge and function as flood arches . The Pons Aemilius probably had stone piers, with wooden roadbeds and arches. They were rebuilt in stone in 142 BC, and either extended from the abutments to the piers , or vice versa. Throughout Roman history, brick or stone arches were used to support bridges' weight. Roman engineers built bridges with one long arch instead of several smaller ones. This practice made construction easier, as they only needed to build one arch on land, instead of many in water. Roman arches were semi-circular and used voussoirs with equal dimensions and conic sections with equal circumference. Later in Roman history arches started to become semi-circular . Sometimes arches were segmented , or not semicircular. This technique

9990-486: The wooden frame was removed, but the weight of the keystone , the last block to be put in place, held it together. Bridges had abutments at each end and piers in the middle, these two design features carrying most of the bridge's weight. Abutments could be constructed in the many arches of a bridge, allowing each to be built separately. Piers were usually twenty-six feet thick and framed with starlings . The late antique Karamagara Bridge represents an early example of

10101-589: The world until into the 19th century. Augustus Gaius Julius Caesar Augustus (born Gaius Octavius ; 23 September 63 BC – 19 August AD 14), also known as Octavian ( Latin : Octavianus ), was the founder of the Roman Empire . He reigned as the first Roman emperor from 27 BC until his death in AD ;14. The reign of Augustus initiated an imperial cult , as well as an era of imperial peace (the Pax Romana or Pax Augusta ) in which

10212-505: Was a military tribune in Sicily during the Second Punic War . His grandfather had served in several local political offices. His father, also named Octavius, had been governor of Macedonia . His mother, Atia , was the niece of Julius Caesar. His father died in 59 BC when Octavian was four years old. His mother married a former governor of Syria , Lucius Marcius Philippus . Philippus claimed descent from Alexander

10323-534: Was a ratification of Octavian's extra-constitutional power. Through the Senate, Octavian was able to continue the appearance of a still-functional constitution . Feigning reluctance, he accepted a ten-year responsibility of overseeing provinces that were considered chaotic. The provinces ceded to Augustus for that ten-year period comprised much of the conquered Roman world, including all of Hispania and Gaul , Syria , Cilicia , Cyprus, and Egypt . Moreover, command of these provinces provided Octavian with control over

10434-465: Was amassing political support, but Octavian still had the opportunity to rival him as the leading member of the faction supporting Caesar. Antony had lost the support of many Romans and supporters of Caesar when he initially opposed the motion to elevate Caesar to divine status. It is alleged that Antony refused to hand over the money due Octavian as Caesar's adopted heir, possibly on grounds that it would take time to disentangle it from state funds. During

10545-407: Was elected consul with his relative Quintus Pedius as co-consul. Meanwhile, Antony formed an alliance with Marcus Aemilius Lepidus , another leading Caesarian. In a meeting near Bononia in October 43 BC, Octavian, Antony, and Lepidus formed the Second Triumvirate . Their powers were made official by the Senate on 27 November. This explicit arrogation of special powers lasting five years

10656-657: Was elected to the College of Pontiffs in 47 BC. The following year he was put in charge of the Greek games that were staged in honor of the Temple of Venus Genetrix , built by Julius Caesar. According to Nicolaus of Damascus , Octavian wished to join Caesar's staff for his campaign in Africa but gave way when his mother protested. In 46 BC, she consented for him to join Caesar in Hispania , where he planned to fight

10767-486: Was engaged in a romantic affair with her, so he decided to send Octavia back to Rome. Octavian used this to spread propaganda implying that Antony was becoming less than Roman because he rejected a legitimate Roman spouse for an "Oriental paramour ". In 36 BC, Octavian used a political ploy to make himself look less autocratic and Antony more the villain by proclaiming that the civil wars were coming to an end and that he would step down as triumvir—if only Antony would do

10878-529: Was exiled in 36 BC, and Antony was defeated by Octavian at the Battle of Actium in 31 BC. Antony and his wife Cleopatra , the Ptolemaic queen of Egypt , killed themselves during Octavian's invasion of Egypt, which then became a Roman province . After the demise of the Second Triumvirate, Augustus restored the outward facade of the free republic, with governmental power vested in the Roman Senate ,

10989-446: Was inherited by all future emperors and became the de facto main title of the emperor. As a result, modern historians usually regard this event as the beginning of his reign as "emperor". Augustus himself appears to have reckoned his "reign" from 27 BC. Augustus styled himself as Imperator Caesar divi filius , "Commander Caesar son of the deified one". With this title, he boasted his familial link to deified Julius Caesar, and

11100-508: Was invented by the Romans. Segmented arches allowed greater amounts of flood water to pass, preventing the bridge from being swept away and allowing it to be lighter. The Limyra Bridge in southwestern Turkey has 26 segmental arches with an average span-to-rise ratio of 5.3:1, giving the bridge an unusually flat profile unsurpassed for more than a millennium. The late Roman Karamagara Bridge in Cappadocia in eastern Turkey may represent

11211-515: Was left with the province of Africa, stymied by Antony, who conceded Hispania to Octavian instead. Octavian was left to decide where in Italy to settle the tens of thousands of veterans of the Macedonian campaign, whom the triumvirs had promised to discharge. The tens of thousands who had fought on the republican side with Brutus and Cassius could easily ally with a political opponent of Octavian if not appeased, and they also required land. There

11322-523: Was most responsible for the proscriptions and killing. However, the sources agree that enacting the proscriptions was a means by all three factions to eliminate political enemies. Marcus Velleius Paterculus asserted that Octavian tried to avoid proscribing officials whereas Lepidus and Antony were to blame for initiating them. Cassius Dio defended Octavian as trying to spare as many as possible, whereas Antony and Lepidus, being older and involved in politics longer, had many more enemies to deal with. This claim

11433-432: Was motivated in part by a need to raise money to pay the salaries of their troops for the upcoming conflict against Caesar's assassins, Marcus Junius Brutus and Gaius Cassius Longinus . Rewards for their arrest gave incentive for Romans to capture those proscribed, while the assets and properties of those arrested were seized by the triumvirs. Contemporary Roman historians provide conflicting reports as to which triumvir

11544-484: Was no more government-controlled land to allot as settlements for their soldiers, so Octavian had to choose one of two options: alienating many Roman citizens by confiscating their land, or alienating many Roman soldiers who could mount a considerable opposition against him in the Roman heartland. Octavian chose the former. There were as many as eighteen Roman towns affected by the new settlements, with entire populations driven out or at least given partial evictions. There

11655-533: Was popular during this time in the Roman Republic to demean and discredit political opponents by accusing them of having an inappropriate sexual affair. After landing at Lupiae near Brundisium , Octavian learned the contents of Caesar's will, and only then did he decide to become Caesar's political heir as well as heir to two-thirds of his estate. Upon his adoption, Octavian assumed his great-uncle's name Gaius Julius Caesar. Roman citizens adopted into

11766-482: Was reached with the Second Triumvirate's extension for another five-year period beginning in 37 BC. In supporting Octavian, Antony expected to gain support for his own campaign against the Parthian Empire , desiring to avenge Rome's defeat at Carrhae in 53 BC. In an agreement reached at Tarentum , Antony provided 120 ships for Octavian to use against Pompeius, while Octavian was to send 20,000 legionaries to Antony for use against Parthia. Octavian sent only

11877-431: Was rejected by Appian, who maintained that Octavian shared an equal interest with Lepidus and Antony in eradicating his enemies. Suetonius said that Octavian was reluctant to proscribe officials but did pursue his enemies with more vigor than the other triumvirs. Plutarch described the proscriptions as a ruthless and cutthroat swapping of friends and family among Antony, Lepidus, and Octavian. For example, Octavian allowed

11988-651: Was taken by his soldiers back to Alexandria where he died in Cleopatra's arms. Cleopatra died soon after by poisoning, contrary to the popular belief that she was bitten by an asp . Octavian had exploited his position as Caesar's heir to further his own political career, and he was well aware of the dangers in allowing another person to do the same. He therefore followed the advice of the Greek philosopher Arius Didymus that "two Caesars are one too many", ordering Caesarion killed while sparing Cleopatra's children by Antony, with

12099-411: Was then legalised by law passed by the plebs , unlike the unofficial First Triumvirate formed by Pompey , Julius Caesar, and Marcus Licinius Crassus . The triumvirs then set in motion proscriptions , in which between 130 and 300 senators and 2,000 equites were branded as outlaws and deprived of their property and, for those who failed to escape, their lives. This decree issued by the triumvirate

12210-444: Was unrivaled in the Roman Republic. Historian Werner Eck states: The sum of his power derived first of all from various powers of office delegated to him by the Senate and people, secondly from his immense private fortune, and thirdly from numerous patron-client relationships he established with individuals and groups throughout the Empire. All of them taken together formed the basis of his auctoritas , which he himself emphasized as

12321-624: Was widespread dissatisfaction with Octavian over these settlements of his soldiers, and this encouraged many to rally at the side of Lucius Antonius , who was brother of Mark Antony and supported by a majority in the Senate. Meanwhile, Octavian asked for a divorce from Claudia , the daughter of Fulvia (Antony's wife) and her first husband Publius Clodius Pulcher . He returned Claudia to her mother, claiming that their marriage had never been consummated. Fulvia decided to take action. Together with Lucius Antonius, she raised an army in Italy to fight for Antony's rights against Octavian. Lucius and Fulvia took
