97-551: Catacombs are man-made underground passages primarily used for religious purposes, particularly for burial. Any chamber used as a burial place is considered a catacomb, although the word is most commonly associated with the Roman Empire . The first place to be referred to as catacombs was the system of underground tombs between the 2nd and 3rd milestones of the Appian Way in Rome , where

194-405: A priestly role . He could not marry a woman from a senatorial family, nor achieve legitimate senatorial rank himself, but during the early Empire, freedmen held key positions in the government bureaucracy, so much so that Hadrian limited their participation by law. The rise of successful freedmen—through political influence or wealth—is a characteristic of early Imperial society. The prosperity of

291-425: A fifth of the population and played a major role in the economy. Slavery was a complex institution that supported traditional Roman social structures as well as contributing economic utility. In urban settings, slaves might be professionals such as teachers, physicians, chefs, and accountants; the majority of slaves provided trained or unskilled labour. Agriculture and industry, such as milling and mining, relied on

388-635: A fine for a crime for which an humilior might receive a scourging . Execution, which was an infrequent legal penalty for free men under the Republic, could be quick and relatively painless for honestiores , while humiliores might suffer the kinds of torturous death previously reserved for slaves, such as crucifixion and condemnation to the beasts . In the early Empire, those who converted to Christianity could lose their standing as honestiores , especially if they declined to fulfil religious responsibilities, and thus became subject to punishments that created

485-425: A freedman were born free, with full rights of citizenship. After manumission, a slave who had belonged to a Roman citizen enjoyed active political freedom ( libertas ), including the right to vote. His former master became his patron ( patronus ): the two continued to have customary and legal obligations to each other. A freedman was not entitled to hold public office or the highest state priesthoods, but could play

582-617: A high-achieving group of freedmen is attested by inscriptions throughout the Empire . The Latin word ordo (plural ordines ) is translated variously and inexactly into English as "class, order, rank". One purpose of the Roman census was to determine the ordo to which an individual belonged. Two of the highest ordines in Rome were the senatorial and equestrian. Outside Rome, cities or colonies were led by decurions , also known as curiales . "Senator"

679-565: A higher social class. Most of the emperors were bilingual but had a preference for Latin in the public sphere for political reasons, a "rule" that first started during the Punic Wars . Different emperors up until Justinian would attempt to require the use of Latin in various sections of the administration but there is no evidence that a linguistic imperialism existed during the early Empire. After all freeborn inhabitants were universally enfranchised in 212 , many Roman citizens would have lacked

776-401: A household or workplace, a hierarchy of slaves might exist, with one slave acting as the master of others. Talented slaves might accumulate a large enough peculium to justify their freedom, or be manumitted for services rendered. Manumission had become frequent enough that in 2 BC a law ( Lex Fufia Caninia ) limited the number of slaves an owner was allowed to free in his will. Following

873-465: A knowledge of Latin. The wide use of Koine Greek was what enabled the spread of Christianity and reflects its role as the lingua franca of the Mediterranean during the time of the Empire. Following Diocletian's reforms in the 3rd century CE, there was a decline in the knowledge of Greek in the west. Spoken Latin later fragmented into the incipient romance languages in the 7th century CE following

970-403: A large effect upon the concrete's reaction to chlorides. Today's water repellents help create a vapor permeable barrier; liquid water, especially from wind driven rains, will stay out of the brick and masonry. Water vapor from the interior of the building, or from the underside of pavers can escape. This will reduce efflorescence, spalling and scaling that can occur from water being trapped inside

1067-513: A lasting influence on the development of language , religion , art , architecture , literature , philosophy , law , and forms of government across its territories. Latin evolved into the Romance languages while Medieval Greek became the language of the East. The Empire's adoption of Christianity resulted in the formation of medieval Christendom . Roman and Greek art had a profound impact on

1164-454: A man as an equestrian. The census of 28 BC uncovered large numbers of men who qualified, and in 14 AD, a thousand equestrians were registered at Cádiz and Padua alone. Equestrians rose through a military career track ( tres militiae ) to become highly placed prefects and procurators within the Imperial administration. The rise of provincial men to the senatorial and equestrian orders

1261-554: A married woman could have sex only with her husband, but a married man did not commit adultery if he had sex with a prostitute or person of marginalized status. Childbearing was encouraged: a woman who had given birth to three children was granted symbolic honours and greater legal freedom (the ius trium liberorum ). At the time of Augustus, as many as 35% of the people in Roman Italy were slaves, making Rome one of five historical "slave societies" in which slaves constituted at least

1358-507: A result of the heat of hydration as cement stone is being formed, brings salts to the surface that are not commonly bound as part of the cement stone. As the water evaporates, it leaves the salt behind, which forms a white, fluffy deposit, that can normally be brushed off. The resulting white deposits are referred to as "efflorescence" in this instance. In this context efflorescence is sometimes referred to as "saltpetering." Since primary efflorescence brings out salts that are not ordinarily part of

1455-427: A sense of "Romanness". Roman society had multiple, overlapping social hierarchies . The civil war preceding Augustus caused upheaval, but did not effect an immediate redistribution of wealth and social power. From the perspective of the lower classes, a peak was merely added to the social pyramid. Personal relationships— patronage , friendship ( amicitia ), family , marriage —continued to influence politics. By

1552-507: A slave's rapist had to be prosecuted by the owner for property damage under the Aquilian Law . Slaves had no right to the form of legal marriage called conubium , but their unions were sometimes recognized. Technically, a slave could not own property, but a slave who conducted business might be given access to an individual fund ( peculium ) that he could use, depending on the degree of trust and co-operation between owner and slave. Within

1649-403: Is a common traffic infrastructure and building maintenance concern. Secondary efflorescence is akin to osteoporosis of the concrete. For controlling secondary efflorescence, admixtures containing aqueous-based calcium stearate dispersion (CSD) are often added at a later stage of the batching process with the mix water. In a typical batching process, sand is first charged into the mixer, then

1746-545: Is an aspect of social mobility in the early Empire. Roman aristocracy was based on competition, and unlike later European nobility , a Roman family could not maintain its position merely through hereditary succession or having title to lands. Admission to the higher ordines brought distinction and privileges, but also responsibilities. In antiquity, a city depended on its leading citizens to fund public works, events, and services ( munera ). Maintaining one's rank required massive personal expenditures. Decurions were so vital for

1843-456: Is by using special admixtures that chemically react with and bind the salt-based impurities in the concrete when hydrogen (H) is present. The chemical reaction in these special additives fuses the sodium chloride on a nanomolecular level, converting it into non-sodium chemicals and other harmless matter that will not leach out or migrate to the surface. In fact, the nanotechnology in these additives can be up to 100,000 times smaller than even

1940-462: Is distributed uniformly throughout the concrete batch mix. Secondary efflorescence is named such as it does not occur as a result of the forming of the cement stone or its accompanying hydration products. Rather, it is usually due to the external influence of concrete poisons, such as chlorides. A very common example of where secondary efflorescence occurs is steel-reinforced concrete bridges as well as parking garages. Saline solutions are formed due to

2037-478: Is the Ichthys , or "Monogram of Christ" which reads ΙΧΘΥΣ, standing for "Jesus Christ, Son of God, Savior". In recent years unique strains of bacteria have been discovered that thrive in catacombs, inducing mineral efflorescence and decay. These include Kribbella sancticallisti , Kribbella catacumbae , and three types of non-thermophilic (low-temperature) Rubrobacter . Roman Empire The Roman Empire

2134-613: Is traditionally regarded as the Pax Romana ("Roman Peace"). The cohesion of the empire was furthered by a degree of social stability and economic prosperity that Rome had never before experienced. Uprisings in the provinces were infrequent and put down "mercilessly and swiftly". The success of Augustus in establishing principles of dynastic succession was limited by his outliving a number of talented potential heirs. The Julio-Claudian dynasty lasted for four more emperors— Tiberius , Caligula , Claudius , and Nero —before it yielded in 69 AD to

2231-590: The Battle of Actium in 31 BC. In 27 BC the Senate gave him the title Augustus ("venerated") and made him princeps ("foremost") with proconsular imperium , thus beginning the Principate , the first epoch of Roman imperial history. Although the republic stood in name, Augustus had all meaningful authority. During his 40-year rule, a new constitutional order emerged so that, upon his death, Tiberius would succeed him as

2328-470: The Dominate . The emperor was the ultimate authority in policy- and decision-making, but in the early Principate, he was expected to be accessible and deal personally with official business and petitions. A bureaucracy formed around him only gradually. The Julio-Claudian emperors relied on an informal body of advisors that included not only senators and equestrians, but trusted slaves and freedmen. After Nero,

2425-666: The Huns of Attila , led to the decline of the Western Roman Empire . With the fall of Ravenna to the Germanic Herulians and the deposition of Romulus Augustus in 476 by Odoacer , the Western Empire finally collapsed. The Eastern Roman Empire survived for another millennium with Constantinople as its sole capital, until the city's fall in 1453. Due to the Empire's extent and endurance, its institutions and culture had

2522-533: The Italian Renaissance . Rome's architectural tradition served as the basis for Romanesque , Renaissance and Neoclassical architecture , influencing Islamic architecture . The rediscovery of classical science and technology (which formed the basis for Islamic science ) in medieval Europe contributed to the Scientific Renaissance and Scientific Revolution . Many modern legal systems, such as

2619-615: The Mediterranean and beyond. However, it was severely destabilised by civil wars and political conflicts , which culminated in the victory of Octavian over Mark Antony and Cleopatra at the Battle of Actium in 31 BC, and the subsequent conquest of the Ptolemaic Kingdom in Egypt. In 27 BC, the Roman Senate granted Octavian overarching military power ( imperium ) and

2716-691: The Napoleonic Code , descend from Roman law. Rome's republican institutions have influenced the Italian city-state republics of the medieval period, the early United States , and modern democratic republics . Rome had begun expanding shortly after the founding of the Roman Republic in the 6th century BC, though not outside the Italian Peninsula until the 3rd century BC. Thus, it was an "empire" (a great power) long before it had an emperor. The Republic

2813-466: The Nile Valley in Egypt. The empire completely circled the Mediterranean  ... referred to by its conquerors as mare nostrum —'our sea'. Trajan's successor Hadrian adopted a policy of maintaining rather than expanding the empire. Borders ( fines ) were marked, and the frontiers ( limites ) patrolled. The most heavily fortified borders were the most unstable. Hadrian's Wall , which separated

2910-495: The Pax Romana ( lit.   ' Roman Peace ' ). Rome reached its greatest territorial extent under Trajan ( r.  98–117 AD ), but a period of increasing trouble and decline began under Commodus ( r.  180–192 ). In the 3rd century, the Empire underwent a 49-year crisis that threatened its existence due to civil war, plagues and barbarian invasions . The Gallic and Palmyrene empires broke away from

3007-590: The Servile Wars of the Republic, legislation under Augustus and his successors shows a driving concern for controlling the threat of rebellions through limiting the size of work groups, and for hunting down fugitive slaves. Over time slaves gained increased legal protection, including the right to file complaints against their masters. A bill of sale might contain a clause stipulating that the slave could not be employed for prostitution, as prostitutes in ancient Rome were often slaves. The burgeoning trade in eunuchs in

3104-605: The 600-member body by appointment. A senator's son belonged to the ordo senatorius , but he had to qualify on his own merits for admission to the Senate. A senator could be removed for violating moral standards. In the time of Nero, senators were still primarily from Italy , with some from the Iberian peninsula and southern France; men from the Greek-speaking provinces of the East began to be added under Vespasian. The first senator from

3201-400: The 6th and 7th centuries with the disintegration of the complex Imperial economy. Laws pertaining to slavery were "extremely intricate". Slaves were considered property and had no legal personhood . They could be subjected to forms of corporal punishment not normally exercised on citizens, sexual exploitation , torture, and summary execution . A slave could not as a matter of law be raped;

3298-452: The Augustan programme to restore traditional morality and social order, moral legislation attempted to regulate conduct as a means of promoting " family values ". Adultery was criminalized, and defined broadly as an illicit sex act ( stuprum ) between a male citizen and a married woman, or between a married woman and any man other than her husband. That is, a double standard was in place:

3395-513: The Empire was engulfed by the Crisis of the Third Century , a period of invasions , civil strife , economic disorder , and plague . In defining historical epochs , this crisis sometimes marks the transition from Classical to Late Antiquity . Aurelian ( r.  270–275 ) stabilised the empire militarily and Diocletian reorganised and restored much of it in 285. Diocletian's reign brought

3492-602: The Middle East. The Latin phrase imperium sine fine ("empire without end" ) expressed the ideology that neither time nor space limited the Empire. In Virgil 's Aeneid , limitless empire is said to be granted to the Romans by Jupiter . This claim of universal dominion was renewed when the Empire came under Christian rule in the 4th century. In addition to annexing large regions, the Romans directly altered their geography, for example cutting down entire forests . Roman expansion

3589-658: The Old and New Testaments of the Bible. Much of the sculpture work and art, other than engravings on the walls or tombs, has been preserved in places such as the Museum of Saint John Lateran , Christian Museum of Berlin University, and the Vatican. Three representations of Christ as Orpheus charming animals with peaceful music have been found in the catacombs of Domatilla and St. Callista. Another figure

3686-450: The Rhine and Danube. Roman jurists also show a concern for local languages such as Punic , Gaulish , and Aramaic in assuring the correct understanding of laws and oaths. In Africa , Libyco-Berber and Punic were used in inscriptions into the 2nd century. In Syria , Palmyrene soldiers used their dialect of Aramaic for inscriptions, an exception to the rule that Latin was the language of

3783-606: The Roman Republic ) while greatly extending its power beyond Italy. In 44 BC Julius Caesar was briefly perpetual dictator before being assassinated by a faction that opposed his concentration of power. This faction was driven from Rome and defeated at the Battle of Philippi in 42 BC by Mark Antony and Caesar's adopted son Octavian . Antony and Octavian divided the Roman world between them, but this did not last long. Octavian's forces defeated those of Mark Antony and Cleopatra at

3880-430: The Roman legal concept of imperium , meaning "command" (typically in a military sense). Occasionally, successful consuls or generals were given the honorary title imperator (commander); this is the origin of the word emperor , since this title was always bestowed to the early emperors. Rome suffered a long series of internal conflicts, conspiracies, and civil wars from the late second century BC (see Crisis of

3977-448: The Roman world from what was perceived as an ever-present barbarian threat, is the primary surviving monument of this effort. Latin and Greek were the main languages of the Empire, but the Empire was deliberately multilingual. Andrew Wallace-Hadrill says "The main desire of the Roman government was to make itself understood". At the start of the Empire, knowledge of Greek was useful to pass as educated nobility and knowledge of Latin

4074-449: The account of his achievements ( Res Gestae ) prominently featured the geographical cataloguing of the Empire. Geography alongside meticulous written records were central concerns of Roman Imperial administration . The Empire reached its largest expanse under Trajan ( r.  98–117 ), encompassing 5 million km . The traditional population estimate of 55–60 million inhabitants accounted for between one-sixth and one-fourth of

4171-486: The acid dilution is neutralised with mild diluted detergent, and then well rinsed with water. However, if the source of the water penetration is not addressed efflorescence may reappear. Common rebar protective measures include the use of epoxy coating as well as the use of a slight electrical charge, both of which prevent rusting. One may also use stainless steel rebar. Certain cement types are less resistant to chlorides than others. The choice of cement, therefore, can have

4268-552: The bodies of the apostles Peter and Paul , among others, were said to have been buried. The name of that place in Late Latin was L.L. fem. nom. pl. n. catacumbas (sing. catacumba ) a word of obscure origin, possibly deriving from a proper name or a derivation of the Greek phrase cata cumbas , "near the quarries". The word referred originally only to the Roman catacombs , but was extended by 1836 to refer to any subterranean receptacle of

4365-414: The cement stone, it is not a structural, but, rather, an aesthetic concern. For controlling primary efflorescence, formulations containing liquid fatty acid mixtures (e.g., oleic acid and linoleic acid) have commonly been used. The oily liquid admixture is introduced into the batch mix at an early stage by coating onto the sand particles prior to the introduction of any mix water, so that the oily admixture

4462-417: The centuries-old catacombs of Rome , catacombs of Paris , and other known, some of which include inscriptions, paintings, statues, ornaments, and other items placed in the graves over the years. Most of these decorations were used to identify, immortalize and show respect to the dead. Decorations in the catacombs of Rome were primarily decorated with images and words exalting Christ or depicting scenes from

4559-418: The collapse of the Empire's west. The dominance of Latin and Greek among the literate elite obscure the continuity of other spoken languages within the Empire. Latin, referred to in its spoken form as Vulgar Latin , gradually replaced Celtic and Italic languages . References to interpreters indicate the continuing use of local languages, particularly in Egypt with Coptic , and in military settings along

4656-482: The conditions of martyrdom . The three major elements of the Imperial state were the central government, the military, and the provincial government. The military established control of a territory through war, but after a city or people was brought under treaty, the mission turned to policing: protecting Roman citizens, agricultural fields, and religious sites. The Romans lacked sufficient manpower or resources to rule through force alone. Cooperation with local elites

4753-430: The dead, as in the 18th-century Paris catacombs . The ancient Christians carved the first catacombs from soft tufa rock. (ref)" (World Book Encyclopedia, page 296) All Roman catacombs were located outside city walls since it was illegal to bury a dead body within the city, providing "a place…where martyrs ' tombs could be openly marked" and commemorative services and feasts held safely on sacred days. Catacombs around

4850-481: The deceased emperor's deification. The dominance of the emperor was based on the consolidation of powers from several republican offices. The emperor made himself the central religious authority as pontifex maximus , and centralized the right to declare war, ratify treaties, and negotiate with foreign leaders. While these functions were clearly defined during the Principate , the emperor's powers over time became less constitutional and more monarchical, culminating in

4947-497: The descent "from a kingdom of gold to one of rust and iron", a comment which has led some historians, notably Edward Gibbon , to take Commodus' reign as the beginning of the Empire's decline . In 212, during the reign of Caracalla , Roman citizenship was granted to all freeborn inhabitants of the empire. The Severan dynasty was tumultuous; an emperor's reign was ended routinely by his murder or execution and, following its collapse,

5044-467: The easternmost province, Cappadocia , was admitted under Marcus Aurelius. By the Severan dynasty (193–235), Italians made up less than half the Senate. During the 3rd century, domicile at Rome became impractical, and inscriptions attest to senators who were active in politics and munificence in their homeland ( patria ). Senators were the traditional governing class who rose through the cursus honorum ,

5141-505: The empire's most concerted effort against the perceived threat of Christianity , the " Great Persecution ". Diocletian divided the empire into four regions, each ruled by a separate tetrarch . Confident that he fixed the disorder plaguing Rome, he abdicated along with his co-emperor, but the Tetrarchy collapsed shortly after . Order was eventually restored by Constantine the Great , who became

5238-506: The empire. This legal egalitarianism required a far-reaching revision of existing laws that distinguished between citizens and non-citizens. Freeborn Roman women were considered citizens, but did not vote, hold political office, or serve in the military. A mother's citizen status determined that of her children, as indicated by the phrase ex duobus civibus Romanis natos ("children born of two Roman citizens"). A Roman woman kept her own family name ( nomen ) for life. Children most often took

5335-609: The end of the Western Roman Empire in 476, when Romulus Augustulus was forced to abdicate to the Germanic warlord Odoacer . Odoacer ended the Western Empire by declaring Zeno sole emperor and placing himself as Zeno's nominal subordinate. In reality, Italy was ruled by Odoacer alone. The Eastern Roman Empire, called the Byzantine Empire by later historians, continued until the reign of Constantine XI Palaiologos ,

5432-498: The exploitation of slaves. Outside Italy, slaves were on average an estimated 10 to 20% of the population, sparse in Roman Egypt but more concentrated in some Greek areas. Expanding Roman ownership of arable land and industries affected preexisting practices of slavery in the provinces. Although slavery has often been regarded as waning in the 3rd and 4th centuries, it remained an integral part of Roman society until gradually ceasing in

5529-457: The father's name, with some exceptions. Women could own property, enter contracts, and engage in business. Inscriptions throughout the Empire honour women as benefactors in funding public works, an indication they could hold considerable fortunes. The archaic manus marriage in which the woman was subject to her husband's authority was largely abandoned by the Imperial era, and a married woman retained ownership of any property she brought into

5626-619: The first emperor to convert to Christianity , and who established Constantinople as the new capital of the Eastern Empire. During the decades of the Constantinian and Valentinian dynasties, the empire was divided along an east–west axis, with dual power centres in Constantinople and Rome. Julian , who under the influence of his adviser Mardonius attempted to restore Classical Roman and Hellenistic religion , only briefly interrupted

5723-456: The functioning of cities that in the later Empire, as the ranks of the town councils became depleted, those who had risen to the Senate were encouraged to return to their hometowns, in an effort to sustain civic life. In the later Empire, the dignitas ("worth, esteem") that attended on senatorial or equestrian rank was refined further with titles such as vir illustris ("illustrious man"). The appellation clarissimus (Greek lamprotatos )

5820-664: The historian Christopher Kelly described it: Then the empire stretched from Hadrian's Wall in drizzle-soaked northern England to the sun-baked banks of the Euphrates in Syria; from the great Rhine – Danube river system, which snaked across the fertile, flat lands of Europe from the Low Countries to the Black Sea , to the rich plains of the North African coast and the luxuriant gash of

5917-537: The influence of the latter was regarded with suspicion, and the emperor's council ( consilium ) became subject to official appointment for greater transparency . Though the Senate took a lead in policy discussions until the end of the Antonine dynasty , equestrians played an increasingly important role in the consilium . The women of the emperor's family often intervened directly in his decisions. Efflorescence In what has been described as "primary efflorescence",

6014-515: The last Roman emperor. He died in battle in 1453 against Mehmed II and his Ottoman forces during the siege of Constantinople . Mehmed II adopted the title of caesar in an attempt to claim a connection to the former Empire. His claim was soon recognized by the Patriarchate of Constantinople , but not by most European monarchs. The Roman Empire was one of the largest in history, with contiguous territories throughout Europe, North Africa, and

6111-588: The late 1st century prompted legislation that prohibited the castration of a slave against his will "for lust or gain". Roman slavery was not based on race . Generally, slaves in Italy were indigenous Italians, with a minority of foreigners (including both slaves and freedmen) estimated at 5% of the total in the capital at its peak, where their number was largest. Foreign slaves had higher mortality and lower birth rates than natives, and were sometimes even subjected to mass expulsions. The average recorded age at death for

6208-597: The local languages' plural katakomby ) also refers to the network of abandoned caves and tunnels earlier used to mine stone, especially limestone . In Italy, possible Catacombs are also located in Alezio , beside the Sanctuary of Santa Maria dell'Assunta , as well as the basement of Santa Maria della Lizza Sanctuary  [ it ] . Catacombs, although most notable as underground passageways and cemeteries, also house many decorations. There are thousands of decorations in

6305-486: The marriage. Technically she remained under her father's legal authority, even though she moved into her husband's home, but when her father died she became legally emancipated. This arrangement was a factor in the degree of independence Roman women enjoyed compared to many other cultures up to the modern period: although she had to answer to her father in legal matters, she was free of his direct scrutiny in daily life, and her husband had no legal power over her. Although it

6402-503: The material with an impregnating, hydro-phobic sealer. This is a sealer that repels water and will penetrate deeply enough into the material to keep water and dissolved salts well away from the surface. However, in climates where freezing is a concern, such a sealer may lead to damage from freeze/thaw cycles. And while it will help to protect against efflorescence, it cannot permanently prevent the problem. Efflorescence can often be removed from concrete using phosphoric acid. After application

6499-416: The members of the three higher "orders", along with certain military officers. The granting of universal citizenship in 212 seems to have increased the competitive urge among the upper classes to have their superiority affirmed, particularly within the justice system. Sentencing depended on the judgment of the presiding official as to the relative "worth" ( dignitas ) of the defendant: an honestior could pay

6596-719: The military. The last reference to Gaulish was between 560 and 575. The emergent Gallo-Romance languages would then be shaped by Gaulish. Proto-Basque or Aquitanian evolved with Latin loan words to modern Basque . The Thracian language , as were several now-extinct languages in Anatolia, are attested in Imperial-era inscriptions. The Empire was remarkably multicultural, with "astonishing cohesive capacity" to create shared identity while encompassing diverse peoples. Public monuments and communal spaces open to all—such as forums , amphitheatres , racetracks and baths —helped foster

6693-565: The mix may render the resulting concrete masonry unit water repellent, as CSD particles are well distributed in the pores of the unit to interfere with the capillary movement of water. Calthemite is also a secondary deposit derived from concrete, mortar or lime, which can be mistakenly assumed to be efflorescence. Calthemites are usually deposited as calcite which is the most stable polymorph of calcium carbonate (CaCO 3 ). The only way to completely and permanently prevent (both primary and secondary) efflorescence in cementitious materials

6790-444: The new de facto monarch. As Roman provinces were being established throughout 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 200 years that began with Augustus's rule

6887-407: The new title of Augustus , marking his accession as the first Roman emperor . The vast Roman territories were organized into senatorial provinces, governed by proconsuls who were appointed by lot annually, and imperial provinces, which belonged to the emperor but were governed by legates . The first two centuries of the Empire saw a period of unprecedented stability and prosperity known as

6984-535: The oil-based primary anti-efflorescence admixture is added with constant mixing to allow the oil to coat the sand. Then coarse aggregates, colorants, and cement are added, followed by water. If CSD is used, it is then introduced usually at this point during or after the addition of the mix water. CSD is an aqueous dispersion wherein fine solid particles of calcium stearate are suspended in the water uniformly. Commercially available CSD has an average particle size of about 1 to 10 micrometres. The uniform distribution of CSD in

7081-412: The political career track, but equestrians often possessed greater wealth and political power. Membership in the equestrian order was based on property; in Rome's early days, equites or knights had been distinguished by their ability to serve as mounted warriors, but cavalry service was a separate function in the Empire. A census valuation of 400,000 sesterces and three generations of free birth qualified

7178-507: The poor were other sources. Vernae , by contrast, were "homegrown" slaves born to female slaves within the household, estate or farm. Although they had no special legal status, an owner who mistreated or failed to care for his vernae faced social disapproval, as they were considered part of the family household and in some cases might actually be the children of free males in the family. Rome differed from Greek city-states in allowing freed slaves to become citizens; any future children of

7275-438: The pores of porous materials, resulting in the destruction of those materials by internal water pressure, as seen in the spalling of brick. Primary efflorescence is named such, as it typically occurs during the initial cure of a cementitious product. It often occurs on masonry construction, particularly brick , as well as some firestop mortars , when water moving through a wall or other structure, or water being driven out as

7372-411: The presence of road salt in the winter. This saline solution is absorbed into the concrete, where it can begin to dissolve cement stone, which is of primary structural importance. Virtual stalactites can be formed in some cases as a result of dissolved cement stone, hanging off cracks in concrete structures. Where this process has taken hold, the structural integrity of a concrete element is at risk. This

7469-528: The slaves of the city of Rome was seventeen and a half years (17.2 for males; 17.9 for females). During the period of republican expansionism when slavery had become pervasive, war captives were a main source of slaves. The range of ethnicities among slaves to some extent reflected that of the armies Rome defeated in war, and the conquest of Greece brought a number of highly skilled and educated slaves. Slaves were also traded in markets and sometimes sold by pirates . Infant abandonment and self-enslavement among

7566-477: The smallest cement particles, allowing their molecules to literally pass through cement minerals or sand particles and ultimately become part of the cement or sand with which they react. And since they require the presence of hydrogen they stop reacting as the concrete dries out and begin reacting again when the concrete is exposed to moisture. It is also possible to protect porous building materials such as brick, tiles, and concrete against efflorescence by treating

7663-636: The state and a series of short-lived emperors led the Empire, which was later reunified under Aurelian ( r.  270–275 ). The civil wars ended with the victory of Diocletian ( r.  284–305 ), who set up two different imperial courts in the Greek East and Latin West . Constantine the Great ( r.  306–337 ), the first Christian emperor , moved the imperial seat from Rome to Byzantium in 330, and renamed it Constantinople . The Migration Period , involving large invasions by Germanic peoples and by

7760-522: The strife-torn Year of the Four Emperors , from which Vespasian emerged as the victor. Vespasian became the founder of the brief Flavian dynasty , followed by the Nerva–Antonine dynasty which produced the " Five Good Emperors ": Nerva , Trajan , Hadrian , Antoninus Pius , and Marcus Aurelius . In the view of contemporary Greek historian Cassius Dio , the accession of Commodus in 180 marked

7857-461: The succession of Christian emperors. Theodosius I , the last emperor to rule over both East and West, died in 395 after making Christianity the state religion . The Western Roman Empire began to disintegrate in the early 5th century. The Romans fought off all invaders, most famously Attila , but the empire had assimilated so many Germanic peoples of dubious loyalty to Rome that the empire started to dismember itself. Most chronologies place

7954-562: The time of Nero , however, it was not unusual to find a former slave who was richer than a freeborn citizen, or an equestrian who exercised greater power than a senator. The blurring of the Republic's more rigid hierarchies led to increased social mobility , both upward and downward, to a greater extent than all other well-documented ancient societies. Women, freedmen, and slaves had opportunities to profit and exercise influence in ways previously less available to them. Social life, particularly for those whose personal resources were limited,

8051-535: The water is the invader and the salt was already present internally, and a reverse process, where the salt is originally present externally and is then carried inside in solution, is referred to as "secondary efflorescence". Efflorescences can occur in natural and built environments. On porous construction materials it may present a cosmetic outer problem only (primary efflorescence causing staining), but can sometimes indicate internal structural weakness (migration/degradation of component materials). Efflorescence may clog

8148-901: The world include: There are also catacomb-like burial chambers in Anatolia , Turkey ; in Sousse , Tunisia; in Syracuse, Italy ; Trier , Germany; Kyiv , Ukraine. Capuchin catacombs of Palermo, Sicily , were used as late as the 1920s. Catacombs were available in some of the grander English cemeteries founded in the 19th century, such as Sheffield General Cemetery (above ground) and West Norwood Cemetery (below ground). There are catacombs in Bulgaria near Aladzha Monastery and in Romania as medieval underground galleries in Bucharest . In Ukraine and Russia, catacomb (used in

8245-411: The world's total population and made it the most populous unified political entity in the West until the mid-19th century. Recent demographic studies have argued for a population peak from 70 million to more than 100 million . Each of the three largest cities in the Empire – Rome, Alexandria , and Antioch – was almost twice the size of any European city at the beginning of the 17th century. As

8342-442: Was a point of pride to be a "one-man woman" ( univira ) who had married only once, there was little stigma attached to divorce , nor to speedy remarriage after being widowed or divorced. Girls had equal inheritance rights with boys if their father died without leaving a will. A mother's right to own and dispose of property, including setting the terms of her will, gave her enormous influence over her sons into adulthood. As part of

8439-465: Was further defined by their citizenship. Most citizens held limited rights (such as the ius Latinum , "Latin right"), but were entitled to legal protections and privileges not enjoyed by non-citizens. Free people not considered citizens, but living within the Roman world, were peregrini , non-Romans. In 212, the Constitutio Antoniniana extended citizenship to all freeborn inhabitants of

8536-466: Was further fostered by a proliferation of voluntary associations and confraternities ( collegia and sodalitates ): professional and trade guilds, veterans' groups, religious sodalities, drinking and dining clubs, performing troupes, and burial societies . According to the jurist Gaius , the essential distinction in the Roman " law of persons " was that all humans were either free ( liberi ) or slaves ( servi ). The legal status of free persons

8633-460: Was made of gilded glass and dates back to the fourth century, featuring Jesus with the world balanced in his hand and a scroll at his feet. Although thousands of inscriptions were lost as time passed, many of those remaining indicate the social rank or job title of its inhabitants; however, most of the inscriptions simply indicate how loving a couple was, or the love of parents and such. A common and particularly interesting one found in Roman catacombs

8730-589: Was mostly accomplished under the Republic , though parts of northern Europe were conquered in the 1st century, when Roman control in Europe, Africa, and Asia was strengthened. Under Augustus , a "global map of the known world" was displayed for the first time in public at Rome, coinciding with the creation of the most comprehensive political geography that survives from antiquity, the Geography of Strabo . When Augustus died,

8827-671: Was necessary to maintain order, collect information, and extract revenue. The Romans often exploited internal political divisions. Communities with demonstrated loyalty to Rome retained their own laws, could collect their own taxes locally, and in exceptional cases were exempt from Roman taxation. Legal privileges and relative independence incentivized compliance. Roman government was thus limited , but efficient in its use of available resources. The Imperial cult of ancient Rome identified emperors and some members of their families with divinely sanctioned authority ( auctoritas ). The rite of apotheosis (also called consecratio ) signified

8924-416: Was never a legal requirement for Latin in the Empire, but it represented a certain status. High standards of Latin, Latinitas , started with the advent of Latin literature. Due to the flexible language policy of the Empire, a natural competition of language emerged that spurred Latinitas , to defend Latin against the stronger cultural influence of Greek. Over time Latin usage was used to project power and

9021-445: Was not a nation-state in the modern sense, but a network of self-ruled towns (with varying degrees of independence from the Senate ) and provinces administered by military commanders. It was governed by annually elected magistrates ( Roman consuls above all) in conjunction with the Senate. The 1st century BC was a time of political and military upheaval, which ultimately led to rule by emperors. The consuls' military power rested in

9118-426: Was not itself an elected office in ancient Rome; an individual gained admission to the Senate after he had been elected to and served at least one term as an executive magistrate . A senator also had to meet a minimum property requirement of 1 million sestertii . Not all men who qualified for the ordo senatorius chose to take a Senate seat, which required legal domicile at Rome. Emperors often filled vacancies in

9215-485: Was the era of Roman civilisation lasting from 27 BC to 476 AD. Rome ruled the Mediterranean and much of Europe, Western Asia and North Africa. The Romans conquered most of this during the Republic , and it was ruled by emperors following Octavian 's assumption of effective sole rule in 27 BC. The western empire collapsed in 476 AD, but the eastern empire lasted until the fall of Constantinople in 1453. By 100 BC, Rome had expanded its rule to most of

9312-447: Was used to designate the dignitas of certain senators and their immediate family, including women. "Grades" of equestrian status proliferated. As the republican principle of citizens' equality under the law faded, the symbolic and social privileges of the upper classes led to an informal division of Roman society into those who had acquired greater honours ( honestiores ) and humbler folk ( humiliores ). In general, honestiores were

9409-476: Was useful for a career in the military, government, or law. Bilingual inscriptions indicate the everyday interpenetration of the two languages. Latin and Greek's mutual linguistic and cultural influence is a complex topic. Latin words incorporated into Greek were very common by the early imperial era, especially for military, administration, and trade and commerce matters. Greek grammar, literature, poetry and philosophy shaped Latin language and culture. There
