168-821: The Chi-Rho symbol was used by the Roman Emperor Constantine the Great (r. 306–337 AD) as part of a military standard ( vexillum ). Constantine's standard was known as the Labarum . Early symbols similar to the Chi Rho were the Staurogram ( [REDACTED] ) and the IX monogram ( [REDACTED] ). In pre-Christian times, the Chi-Rho symbol was also used to mark a particularly valuable or relevant passage in

336-565: A social science and a branch of the humanities . It is usually considered an independent academic discipline , but may also be classified as part of anthropology (in North America – the four-field approach ), history or geography . Archaeologists study human prehistory and history, from the development of the first stone tools at Lomekwi in East Africa 3.3 million years ago up until recent decades. Archaeology

504-608: A theocracy . According to George Ostrogorsky , "the absolute power of the Roman emperor was further increased with the advent of Christian ideas". This became more evident after the Muslim conquests of the 7th century, which gave Byzantine imperialism a new sense of purpose. The emperor was the subject of a series of rites and ceremonies, including a formal coronation performed by the Patriarch of Constantinople . The Byzantine state

672-519: A 50-year period that almost saw the end of the Roman Empire. The last vestiges of Republicanism were lost in the ensuing anarchy. In 238, the Senate attempted to regain power by proclaiming Pupienus and Balbinus as their own emperors (the first time since Nerva ). They managed to usurp power from Maximinus Thrax , but they were killed within two months. With the rise of the "soldier emperors",

840-598: A 5th-century chalice covered in religious iconography, including the Chi-Rho. In Insular Gospel books , the beginning of Matthew 1:18, at the end of his account of the genealogy of Christ and introducing his account of the life, so representing the moment of the Incarnation of Christ , was usually marked with a heavily decorated page, where the letters of the first word "Christi" are abbreviated and written in Greek as "XPI", and often almost submerged by decoration. Though

1008-464: A basic level of analysis, artifacts found are cleaned, catalogued and compared to published collections. This comparison process often involves classifying them typologically and identifying other sites with similar artifact assemblages. However, a much more comprehensive range of analytical techniques are available through archaeological science , meaning that artifacts can be dated and their compositions examined. Bones, plants, and pollen collected from

1176-563: A big impact throughout Europe. However, prior to the development of modern techniques, excavations tended to be haphazard; the importance of concepts such as stratification and context were overlooked. In the mid-18th century, the German Johann Joachim Winckelmann lived in Rome and devoted himself to the study of Roman antiquities, gradually acquiring an unrivalled knowledge of ancient art. Then, he visited

1344-401: A clear objective as to what the archaeologists are looking to achieve must be agreed upon. This done, a site is surveyed to find out as much as possible about it and the surrounding area. Second, an excavation may take place to uncover any archaeological features buried under the ground. And, third, the information collected during the excavation is studied and evaluated in an attempt to achieve

1512-546: A court title bestowed to prominent figures of the government, and lost even more relevance after the creation of the title sebastokrator by Alexios I Komnenos . Despite this, its regular use by earlier emperors led to the name becoming synonym with "emperor" in certain regions. Several countries use Caesar as the origin of their word for "emperor", like Kaiser in Germany and Tsar in Bulgaria and Russia . After

1680-544: A family name ( nomen ), styling himself as Imp. Caesar instead of Imp. Julius Caesar . However, the nomen was still inherited by women (such as Julia the Younger ) and appear in some inscriptions. After the death of Caligula , Augustus' great-grandson, his uncle Claudius was proclaimed emperor. He was not an official member of the Julia gens , but he was the grandson of Octavia , Augustus' sister, and thus still part of

1848-451: A field survey. Regional survey is the attempt to systematically locate previously unknown sites in a region. Site survey is the attempt to systematically locate features of interest, such as houses and middens , within a site. Each of these two goals may be accomplished with largely the same methods. Survey was not widely practised in the early days of archaeology. Cultural historians and prior researchers were usually content with discovering

2016-484: A lack of public interest, and opposition to the excavation of human remains. In Ancient Mesopotamia , a foundation deposit of the Akkadian Empire ruler Naram-Sin (ruled c.  2200 BC ) was discovered and analysed by king Nabonidus , c.  550 BC , who is thus known as the first archaeologist. Not only did he lead the first excavations which were to find the foundation deposits of

2184-528: A large region or site can be expensive, so archaeologists often employ sampling methods.) As with other forms of non-destructive archaeology, survey avoids ethical issues (of particular concern to descendant peoples) associated with destroying a site through excavation. It is the only way to gather some forms of information, such as settlement patterns and settlement structure. Survey data are commonly assembled into maps , which may show surface features and/or artifact distribution. The simplest survey technique

2352-473: A new caesar . Each pair ruled over a half of the Empire, which led to the creation of a Western and Eastern Roman Empire , a division that eventually became permanent. This division had already a precedent in the joint rule of Valerian / Gallienus and Carus / Carinus . Diocletian justified his rule not by military power, but by claiming divine right . He imitated Oriental divine kingship and encouraged

2520-541: A regime in which the notion of legitimacy is as absent as that of the Augustan principate". Imperial propaganda was often used to legitimize or de-legitimize certain emperors. The Chronicon Paschale , for example, describes Licinius as having been killed like "those who had briefly been usurpers before him". In reality, Licinius was the legitimate emperor of the West (having been appointed by Galerius ), while Constantine

2688-504: A site excavated depends greatly on the country and "method statement" issued. Sampling is even more important in excavation than in survey. Sometimes large mechanical equipment, such as backhoes ( JCBs ), is used in excavation, especially to remove the topsoil ( overburden ), though this method is increasingly used with great caution. Following this rather dramatic step, the exposed area is usually hand-cleaned with trowels or hoes to ensure that all features are apparent. The next task

2856-414: A site reveals its stratigraphy; if a site was occupied by a succession of distinct cultures, artifacts from more recent cultures will lie above those from more ancient cultures. Excavation is the most expensive phase of archaeological research, in relative terms. Also, as a destructive process, it carries ethical concerns. As a result, very few sites are excavated in their entirety. Again the percentage of

3024-408: A sole source. The material record may be closer to a fair representation of society, though it is subject to its own biases, such as sampling bias and differential preservation. Often, archaeology provides the only means to learn of the existence and behaviors of people of the past. Across the millennia many thousands of cultures and societies and billions of people have come and gone of which there

3192-527: A stone wall, will develop more slowly, while those above other types of features (such as middens ) may develop more rapidly. Photographs of ripening grain , which changes colour rapidly at maturation, have revealed buried structures with great precision. Aerial photographs taken at different times of day will help show the outlines of structures by changes in shadows. Aerial survey also employs ultraviolet , infrared , ground-penetrating radar wavelengths, Lidar and thermography . Geophysical survey can be

3360-487: A systematic guide to the ruins and topography of ancient Rome in the early 15th century, for which he has been called an early founder of archaeology. Antiquarians of the 16th century, including John Leland and William Camden , conducted surveys of the English countryside, drawing, describing and interpreting the monuments that they encountered. The OED first cites "archaeologist" from 1824; this soon took over as

3528-495: A wide range of influences, including systems theory , neo-evolutionary thought , [35] phenomenology , postmodernism , agency theory , cognitive science , structural functionalism , Marxism , gender-based and feminist archaeology , queer theory , postcolonial thoughts , materiality , and posthumanism . An archaeological investigation usually involves several distinct phases, each of which employs its own variety of methods. Before any practical work can begin, however,

3696-606: Is distinct from palaeontology , which is the study of fossil remains. Archaeology is particularly important for learning about prehistoric societies, for which, by definition, there are no written records. Prehistory includes over 99% of the human past, from the Paleolithic until the advent of literacy in societies around the world. Archaeology has various goals, which range from understanding culture history to reconstructing past lifeways to documenting and explaining changes in human societies through time. Derived from Greek,

3864-561: Is known as the Dominate , derived from the title dominus ("lord") adopted by Diocletian . During his rule, the emperor became an absolute ruler and the regime became even more monarchical. The emperors adopted the diadem crown as their supreme symbol of power, abandoning the subtleties of the early Empire. Beginning in the late 2nd century, the Empire began to suffer a series of political and economic crises, partially because it had overexpanded so much. The Pax Romana ("Roman peace")

4032-451: Is little or no written record or existing records are misrepresentative or incomplete. Writing as it is known today did not exist in human civilization until the 4th millennium BC, in a relatively small number of technologically advanced civilizations. In contrast, Homo sapiens has existed for at least 200,000 years, and other species of Homo for millions of years (see Human evolution ). These civilizations are, not coincidentally,

4200-598: Is never used. The imperial titles are treated as inseparable of the person, which is reflected in the name Imperator Caesar Vespasianus Augustus . This Lex sometimes related to the Lex regia ("royal law") mentioned in the Corpus Juris Civilis of Eastern emperor Justinian I (r. 527–565), who cites the early 3rd-century writer Ulpian . This was probably a later construct, as its very name, which derives from rex ("king"), would have been utterly rejected in

4368-426: Is no one approach to archaeological theory that has been adhered to by all archaeologists. When archaeology developed in the late 19th century, the first approach to archaeological theory to be practised was that of cultural-historical archaeology , which held the goal of explaining why cultures changed and adapted rather than just highlighting the fact that they did, therefore emphasizing historical particularism . In

4536-633: Is often said to have ended with the tyrannical reign of Commodus. His murder was followed by the accession of Septimius Severus , the victor of the Year of the Five Emperors . It was during his reign that the role of the army grew even more, and the emperors' power increasingly depended on it. The murder of his last relative, Severus Alexander , led to the Crisis of the Third Century (235–285),

4704-520: Is often said to have followed a " Caesaropapist " model, where the emperor played the role of ruler and head of the Church, but there was often a clear distinction between political and secular power. The line of Eastern emperors continued uninterrupted until the sack of Constantinople and the establishment of the Latin Empire in 1204. This led to the creation of three lines of emperors in exile:

Passive instruments sense only radiation emitted by the object being viewed or reflected by the object from a source other than the instrument. Active instruments emit energy and record what is reflected. Satellite imagery is an example of passive remote sensing. Here are two active remote sensing instruments: The archaeological project then continues (or alternatively, begins) with

5040-624: Is said to have come in Gaul long before the Battle of the Milvian Bridge. In this later version, the Roman emperor had been pondering the misfortunes that befell commanders who invoked the help of many different gods, and decided to seek divine aid in the forthcoming battle from the One God. At noon, Constantine saw a cross of light imposed over the sun . Attached to it, in Greek characters, was

Western emperors such as Magnentius , Eugenius and Magnus Maximus are sometimes called usurpers, but Romulus Augustulus is traditionally regarded as the last Western emperor, despite never receiving the recognition of the Eastern emperor Zeno . The period after the Principate

5376-428: Is surface survey. It involves combing an area, usually on foot but sometimes with the use of mechanized transport, to search for features or artifacts visible on the surface. Surface survey cannot detect sites or features that are completely buried under earth, or overgrown with vegetation. Surface survey may also include mini-excavation techniques such as augers , corers, and shovel test pits. If no materials are found,

5544-596: Is through archaeology. Because archaeology is the study of past human activity, it stretches back to about 2.5 million years ago when the first stone tools are found – The Oldowan Industry . Many important developments in human history occurred during prehistory, such as the evolution of humanity during the Paleolithic period, when the hominins developed from the australopithecines in Africa and eventually into modern Homo sapiens . Archaeology also sheds light on many of humanity's technological advances, for instance

5712-431: Is to form a site plan and then use it to help decide the method of excavation. Features dug into the natural subsoil are normally excavated in portions to produce a visible archaeological section for recording. A feature, for example a pit or a ditch, consists of two parts: the cut and the fill . The cut describes the edge of the feature, where the feature meets the natural soil. It is the feature's boundary. The fill

5880-420: Is what the feature is filled with, and will often appear quite distinct from the natural soil. The cut and fill are given consecutive numbers for recording purposes. Scaled plans and sections of individual features are all drawn on site, black and white and colour photographs of them are taken, and recording sheets are filled in describing the context of each. All this information serves as a permanent record of

There is no mention of imperium nor tribunicia potestas , although these powers were probably given in the earlier clauses. There is also no mention of any "imperial office", and the title of "emperor"

6216-583: The Constantinian dynasty , emperors followed Imperator Caesar with Flavius , which also began as a family name but was later incorporated into the emperor's titles, thus becoming Imperator Caesar Flavius . The last use of the formula, rendered as Autokrator Kaisar Flabios... Augoustos (Αὐτοκράτωρ καῖσαρ Φλάβιος αὐγουστος) in Greek, is in the Basilika of Leo VI the Wise (r. 886–912). Originally

The Senate could then award the extraordinary honor of a triumph ; the commander then retained the title until the end of his magistracy . In Roman tradition, the first triumph was that of Romulus , the founder of Rome, but the first attested use of imperator was in 189 BC, on

The title slowly lost importance in the following decades, as emperors started to promote their sons directly to augustus . In the East, the title finally lost its imperial character in 705, when Justinian II awarded it to Tervel of Bulgaria . After this it became

His killers proclaimed themselves as the liberatores ("liberators") and the restorers of the Republic, but their rule was cut short by Caesar's supporters, who almost immediately established a new dictatorship. In his will, Caesar appointed his grandnephew Octavian as his heir and adopted son. He inherited his property and lineage,

The Nicean rulers have been traditionally regarded as the "legitimate" emperors of this period, as they recovered Constantinople and restored the Empire in 1261. The Empire of Trebizond continued to exist for another 200 years, but from 1282 onwards its rulers used the modified title of "Emperor and Autocrat of all

The governors appointed to the imperial provinces only answered to the emperor himself, who could maintain or replace them at will.

Recognition by the Senate is often used to determine the legitimacy of an emperor, but this criterion is not always followed. Maxentius is sometimes called an usurper because he did not have the recognition of Tetrarchs , but he held Rome for several years, and thus had

In 476, the Heruli Odoacer overthrew the child-emperor Romulus Augustulus , made himself king of Italy and shipped the imperial regalia to the Emperor Zeno in Constantinople. Historians mark this date as the date of the fall of the Western Roman Empire , although by this time there was no longer any "Empire" left, as its territory had reduced to Italy. Julius Nepos , who

8232-642: The 1920s and 1930s brought the science on swiftly. Wheeler developed the grid system of excavation , which was further improved by his student Kathleen Kenyon . Archaeology became a professional activity in the first half of the 20th century, and it became possible to study archaeology as a subject in universities and even schools. By the end of the 20th century nearly all professional archaeologists, at least in developed countries, were graduates. Further adaptation and innovation in archaeology continued in this period, when maritime archaeology and urban archaeology became more prevalent and rescue archaeology

8736-573: The 5th century, there was scarcely a single decade without succession conflicts and civil war. During this period, very few emperors died of natural causes. Such problems persisted in the later Eastern Empire, where emperors had to often appoint co-emperors to secure the throne. Despite often working as a hereditary monarchy, there was no law or single principle of succession. Individuals who claimed imperial power "illegally" are referred to as " usurpers " in modern scholarship. Ancient historians refer to these rival emperors as " tyrants ". In reality, there

However, the Byzantine Empire had been reduced mostly to Constantinople, and the rise of other powers such as Serbia and Bulgaria forced the Byzantines to recognize their rulers as basileus . Despite this, emperors continued to view themselves as the rulers of an "universal empire". During the last decades of

9408-432: The Empire always saw the emperor as an open monarch. Starting with Heraclius in 629, Roman emperors styled themselves " basileus ", the traditional title for Greek monarchs used since the times of Alexander the Great . The title was used since the early days of the Empire and became the common imperial title by the 3rd century, but did not appear in official documents until the 7th century. Michael I Rangabe (r. 811–813)

9576-440: The Empire used it regularly. It began to used in official context starting with Septimius Severus , and was first officially adopted in coinage by Aurelian . In the East, imperator was translated as autokrator ("self-ruler"), a title that continued to be used until the end of the Empire. This is the modern Greek word for "emperor" ( υτοκράτορας ). There are still some instances of imperator in official documents as late as

9744-494: The Empire, power was once again shared between multiple emperors and colleagues, each ruling from their own capital, notably during the long reign of John V . Constantinople finally fell to the Ottoman Turks in 1453; its last emperor, Constantine XI Palaiologos , dying in battle. The last vestiges of the empire, Morea and Trebizond , fell in 1461. The title imperator – from imperare , "to command" – dates back to

Under the Tetrarchy, Diocletian set in place a system of two emperors ( augusti ) and two subordinates that also served as heirs ( caesares ).

In September 31 BC, Octavian's victory at Actium put an end to any effective opposition and confirmed his supremacy over Rome. In January 27 BC, Octavian and the Senate concluded the so-called " First settlement ". Until then Octavian had been ruling the state with his powers as triumvir , even though

10920-479: The Senate awarded him the appellation of augustus ("elevated"). The honorific itself held no legal meaning, but it denoted that Octavian (henceforth Augustus ) now approached divinity, and its adoption by his successors made it the de facto main title of the emperor. He also received the civic crown alongside several other insignias in his honor. Augustus now held supreme and indisputable power, and even though he still received subsequent grants of powers, such as

The first emperors reigned alone; later emperors would sometimes rule with co-emperors to secure the succession or to divide the administration of the empire between them. The office of emperor was thought to be distinct from that of a rex ('king'). Augustus, the first emperor, resolutely refused recognition as a monarch. For the first three hundred years of Roman emperors, efforts were made to portray

Regional survey in underwater archaeology uses geophysical or remote sensing devices such as marine magnetometer, side-scan sonar , or sub-bottom sonar.

It can reveal several types of information usually not accessible to survey, such as stratigraphy , three-dimensional structure, and verifiably primary context. Modern excavation techniques require that

11928-505: The West acknowledged the Eastern emperors until the accession of Empress Irene in 797. After this, the papacy created a rival lineage of Roman emperors in western Europe, the Holy Roman Emperors , which ruled the Holy Roman Empire for most of the period between 800 and 1806. These emperors were never recognized in Constantinople and their coronations resulted in the medieval problem of two emperors . The last Eastern emperor

Instead the Eastern emperor Zeno proclaimed himself as the sole emperor of a theoretically undivided Roman Empire (although in practice he had no authority in the West).

The papacy and Germanic kingdoms of

12264-423: The West. The Eastern Greek-speaking half of the Empire had always regarded the emperors as open monarchs ( basileis ), and called them as such. The weakest point of the Augustan institution was its lack of a clear succession system. Formally announcing a successor would have revealed Augustus as a monarch, so he and subsequent emperors opted to adopt their best candidates as their sons and heirs. Primogeniture

Later Eastern imperial dynasties, such as the Doukai and Palaiologoi , claimed descent from Constantine the Great . What turns a "usurper" into a "legitimate" emperor is typically that they managed to gain the recognition of a more senior, legitimate, emperor, or that they managed to defeat a more senior, legitimate emperor and seize power. Modern historiography has not yet defined clear legitimacy criteria for emperors, resulting in some emperors being included or excluded from different lists. The year 193 has traditionally been called

He was one of the founders of scientific archaeology and first applied the categories of style on a large, systematic basis to the history of art He was one of the first to separate Greek art into periods and time classifications. Winckelmann has been called both "The prophet and founding hero of modern archaeology " and

13104-434: The area surveyed is deemed sterile . Aerial survey is conducted using cameras attached to airplanes , balloons , UAVs , or even Kites . A bird's-eye view is useful for quick mapping of large or complex sites. Aerial photographs are used to document the status of the archaeological dig. Aerial imaging can also detect many things not visible from the surface. Plants growing above a buried human-made structure, such as

13272-601: The army and the bureaucracy, so the principle of automatic inheritance was not adopted, which often led to several claimants to the throne . Despite this, elements of the republican institutional framework (Senate, consuls, and magistrates) were preserved even after the end of the Western Empire. Constantine the Great , the first Christian emperor, moved the capital from Rome to Constantinople , formerly known as Byzantium , in 330 AD. Roman emperors had always held high religious offices; under Constantine there arose

13440-560: The artifacts they had found in chronological order. A major figure in the development of archaeology into a rigorous science was army officer and ethnologist Augustus Pitt Rivers , who began excavations on his land in England in the 1880s. Highly methodical by the standards of the time, he is widely regarded as the first scientific archaeologist. He arranged his artifacts by type or " Typology (archaeology) ", and within types chronologically. This style of arrangement, designed to highlight

13608-474: The authority based on prestige. The honorific was awarded as both a name and a title to Octavian in 27 BC and was inherited by all subsequent emperors, who placed it after their personal names. The only emperor to not immediately assume it was Vitellius , although he did use it after his recognition by the Senate. Later emperors ruled alongside one or several junior augusti who held de jure (but not de facto ) equal constitutional power. Despite its use as

13776-523: The battle, when Eusebius had not yet had contact with Constantine, he does not mention any dream or vision, but compares the defeat of Maxentius (drowned in the Tiber ) to that of the biblical pharaoh and credits Constantine's victory to divine protection. In a memoir of the Roman emperor that Eusebius wrote after Constantine's death ( On the Life of Constantine , c.  337 –339), a miraculous appearance

13944-563: The best-known; they are open to the inquiry of historians for centuries, while the study of pre-historic cultures has arisen only recently. Within a literate civilization many events and important human practices may not be officially recorded. Any knowledge of the early years of human civilization – the development of agriculture, cult practices of folk religion, the rise of the first cities – must come from archaeology. In addition to their scientific importance, archaeological remains sometimes have political or cultural significance to descendants of

14112-476: The city and Senate of Rome began to lose importance. Maximinus and Carus , for example, did not even set foot on the city. Carus' successors Carinus and Numerian , the last of the Crisis emperors, did not bother to assume the tribunicia potestas either. After reuniting the Roman Empire in 285, Diocletian began a series of reforms to restore stability. Reaching back to the oldest traditions of job-sharing in

14280-400: The continuance of the Republic. The title had already been used by Pompey and Julius Caesar , among others. It was a purely honorific title with no attached duties or powers, hence why it was never used in official titulature. The title was the most preferred by Augustus as its use implies only "primacy" (is in the " first among equals "), as opposed to dominus , which implies dominance. It

14448-549: The creation of a worship cult . Augustus became pontifex maximus (the chief priest of the College of Pontiffs ) in 12 BC, after the death of the former triumvir Lepidus . Emperors from the reign of Gratian (r. 375–383) onward used the style pontifex inclytus ("honorable pontiff"). The title of pontifex maximus was eventually adopted by the bishops of Rome during the Renaissance . The last known emperors to use

14616-473: The early 20th century, many archaeologists who studied past societies with direct continuing links to existing ones (such as those of Native Americans , Siberians , Mesoamericans etc.) followed the direct historical approach , compared the continuity between the past and contemporary ethnic and cultural groups. In the 1960s, an archaeological movement largely led by American archaeologists like Lewis Binford and Kent Flannery arose that rebelled against

14784-617: The emperor derived from an extraordinary concentration of individual powers and offices that were extant in the Republic and developed under Augustus and later rulers, rather than from a new political office. Under the Republic, these powers would have been split between several people, who would each exercise them with the assistance of a colleague and for a specific period of time. Augustus held them all at once by himself, and with no time limits; even those that nominally had time limits were automatically renewed whenever they lapsed. The Republican offices endured and emperors were regularly elected to

14952-453: The emperors as leaders of the Republic, fearing any association with the kings who ruled Rome prior to the Republic. From Diocletian , whose reformed tetrarchy divided the position into one emperor in the West and one in the East , emperors ruled in an openly monarchic style. Although succession was generally hereditary, it was only hereditary if there was a suitable candidate acceptable to

15120-643: The empirical evidence that existed for the understanding of the past, encapsulated in the motto of the 18th century antiquary, Sir Richard Colt Hoare : "We speak from facts, not theory". Tentative steps towards the systematization of archaeology as a science took place during the Enlightenment period in Europe in the 17th and 18th centuries. In Imperial China during the Song dynasty (960–1279), figures such as Ouyang Xiu and Zhao Mingcheng established

15288-413: The end of the Empire. In the West, the title was also used by Charlemagne and the subsequent Holy Roman Emperors as part of the formula Imperator Augustus . Both Eastern and Western rulers also used the style semper augustus ("forever augustus"). The word princeps , meaning "first", was a republican term used to denote the leading member of the Senate, and it was used by the early emperors to emphasize

15456-644: The established cultural-history archaeology. They proposed a "New Archaeology", which would be more "scientific" and "anthropological", with hypothesis testing and the scientific method very important parts of what became known as processual archaeology . In the 1980s, a new postmodern movement arose led by the British archaeologists Michael Shanks , Christopher Tilley , Daniel Miller , and Ian Hodder , which has become known as post-processual archaeology . It questioned processualism's appeals to scientific positivism and impartiality, and emphasized

15624-633: The evolutionary trends in human artifacts, was of enormous significance for the accurate dating of the objects. His most important methodological innovation was his insistence that all artifacts, not just beautiful or unique ones, be collected and catalogued. William Flinders Petrie is another man who may legitimately be called the Father of Archaeology. His painstaking recording and study of artifacts, both in Egypt and later in Palestine , laid down many of

15792-441: The failure of the Tetrarchy. This practice had first been applied by Septimius Severus , who proclaimed his 10-year-old son Caracalla as augustus . He was followed by Macrinus , who did the same with his 9-year-old son Diadumenian , and several other emperors during the Crisis. This became even more common from the 4th century onwards. Gratian was proclaimed emperor at the age of 8, and his co-ruler and successor Valentinian II

15960-500: The family. Following the suicide of Nero, the last descendant of Caesar, the new emperor Galba adopted the name of Servius Galba Caesar Augustus , thus making it part of the imperial title. Five days before his murder he adopted Piso Licinianus as his son and heir, renaming him as Servius Sulpicius Galba Caesar . After this Caesar came to denote the heir apparent, who would add the name to his own as heir and retain it upon accession as augustus . The only emperor not to assume it

16128-538: The father of the discipline of art history . The father of archaeological excavation was William Cunnington (1754–1810). He undertook excavations in Wiltshire from around 1798, funded by Sir Richard Colt Hoare. Cunnington made meticulous recordings of Neolithic and Bronze Age barrows , and the terms he used to categorize and describe them are still used by archaeologists today. Future U.S. President Thomas Jefferson also did his own excavations in 1784 using

16296-765: The fifteenth century, and the general accuracy of his records entitles him to be called the founding father of modern classical archeology." He traveled throughout Greece and all around the Eastern Mediterranean, to record his findings on ancient buildings, statues and inscriptions, including archaeological remains still unknown to his time: the Parthenon , Delphi , the Egyptian pyramids , the hieroglyphics . He noted down his archaeological discoveries in his diary, Commentaria (in six volumes). Flavio Biondo , an Italian Renaissance humanist historian, created

16464-412: The first emperor, whereas Julius Caesar is considered the last dictator of the Roman Republic , a view that is shared by the Roman writers Plutarch , Tacitus , and Cassius Dio . Conversely, the majority of Roman writers, including Pliny the Younger , Suetonius and Appian , as well as most of the ordinary people of the Empire, thought of Julius Caesar as the first emperor. Caesar did indeed rule

16632-528: The first history books of India. One of the first sites to undergo archaeological excavation was Stonehenge and other megalithic monuments in England. John Aubrey (1626–1697) was a pioneer archaeologist who recorded numerous megalithic and other field monuments in southern England. He was also ahead of his time in the analysis of his findings. He attempted to chart the chronological stylistic evolution of handwriting, medieval architecture, costume, and shield-shapes. Excavations were also carried out by

16800-417: The granting of tribunicia potestas in 23 BC, these were only ratifications of the powers he already possessed. Most modern historians use 27 BC as the start date of the Roman Empire. This is mostly a symbolic date, as the Republic had essentially disappeared many years earlier. Ancient writers often ignore the legal implications of Augustus' reforms and simply write that he "ruled" Rome following

16968-414: The highest imperial title, it was generally not used to indicate the office of Emperor itself, as ordinary people and writers had become accustomed to Imperator . In the East the title was initially translated as Sebastos , but the form Augoustos eventually became more common. Emperors after Heraclius styled themselves as Basileus , but Augoustos still remained in use in a lesser form up until

17136-445: The highest importance in the Republic, making the power attached to those offices permanent, and preventing anyone with similar aspirations from accumulating or maintaining power for themselves. Julius Caesar had been pontifex maximus since 64 BC; held the offices of consul and dictator five times since 59 BC, and was appointed dictator in perpetuity in 44 BC, shortly before his assassination . He had also become

17304-475: The ideas behind modern archaeological recording; he remarked that "I believe the true line of research lies in the noting and comparison of the smallest details." Petrie developed the system of dating layers based on pottery and ceramic findings , which revolutionized the chronological basis of Egyptology . Petrie was the first to scientifically investigate the Great Pyramid in Egypt during the 1880s. He

17472-472: The importance of a more self-critical theoretical reflexivity . However, this approach has been criticized by processualists as lacking scientific rigor, and the validity of both processualism and post-processualism is still under debate. Meanwhile, another theory, known as historical processualism , has emerged seeking to incorporate a focus on process and post-processual archaeology's emphasis of reflexivity and history. Archaeological theory now borrows from

17640-493: The letters are written one after the other and the "X" and "P" not combined in a monogram, these are known as Chi-Rho pages. Famous examples are in the Book of Kells and Book of Lindisfarne . The "X" was regarded as the crux decussata , a symbol of the cross; this idea is found in the works of Isidore of Seville and other patristic and Early Medieval writers. The Book of Kells has a second Chi-Rho abbreviation on folio 124 in

17808-444: The lives and interests of the populace. Writings that were produced by people more representative of the general population were unlikely to find their way into libraries and be preserved there for posterity. Thus, written records tend to reflect the biases, assumptions, cultural values and possibly deceptions of a limited range of individuals, usually a small fraction of the larger population. Hence, written records cannot be trusted as

17976-671: The locations of monumental sites from the local populace, and excavating only the plainly visible features there. Gordon Willey pioneered the technique of regional settlement pattern survey in 1949 in the Viru Valley of coastal Peru , and survey of all levels became prominent with the rise of processual archaeology some years later. Survey work has many benefits if performed as a preliminary exercise to, or even in place of, excavation. It requires relatively little time and expense, because it does not require processing large volumes of soil to search out artifacts. (Nevertheless, surveying

18144-467: The loyalty of most of his allies, and – again through a formal process of senatorial consent – an increasing number of the titles and offices that had accrued to Caesar. In August 43 BC, following the death of both consuls of the year , Octavian marched to Rome and forced the Senate to elect him consul. He then formed the Second Triumvirate alongside Mark Antony and Lepidus , dividing

18312-421: The main title of the emperor. According to Suetonius , it was "not merely a new title but a more honorable one, inasmuch as sacred places too, and those in which anything is consecrated by augural rites are called "august" ( augusta ), from the increase ( auctus ) in dignity". It was also connected to the religious practice of augury , which was itself linked to Rome's founding by Romulus , and to auctoritas ,

18480-460: The margin of a page, abbreviating chrēston (good). Some coins of Ptolemy III Euergetes (r. 246–222 BC) were marked with a Chi-Rho. Although formed of Greek characters, the device (or its separate parts) is frequently found serving as an abbreviation in Latin text, with endings added appropriate to a Latin noun, thus XPo , signifying Christo , "to Christ", the dative form of Christus , or χρ̅icola , signifying Christicola , "Christian", in

18648-472: The marginalization of the former heartland of Italy to the empire had a profound cultural impact on the empire and its emperor, which adopted a more Hellenistic character. The Eastern emperors continued to be recognized in the Western kingdoms until the accession of Irene (r. 797–802), the first empress regnant . The Italian heartland was recovered during the reign of Justinian I (r. 527–565), but this

18816-724: The most effective way to see beneath the ground. Magnetometers detect minute deviations in the Earth's magnetic field caused by iron artifacts, kilns , some types of stone structures , and even ditches and middens. Devices that measure the electrical resistivity of the soil are also widely used. Archaeological features whose electrical resistivity contrasts with that of surrounding soils can be detected and mapped. Some archaeological features (such as those composed of stone or brick) have higher resistivity than typical soils, while others (such as organic deposits or unfired clay) tend to have lower resistivity. Although some archaeologists consider

18984-411: The most prominent of them: the consulship and censorship . This early period of the Empire is known as the " Principate ", derived from the title princeps used by the early emperors. The most important bases of the emperor's power were his supreme power of command ( imperium maius ) and tribunician power ( tribunicia potestas ) as personal qualities, separate from his public office. Originally,

19152-510: The murder of Caesar, or that he "ruled alone" after the death of Mark Antony. Most Romans thus simply saw the "emperor" as the individual that ruled the state, with no specific title or office attached to him. Augustus actively prepared his adopted son Tiberius to be his successor and pleaded his case to the Senate for inheritance on merit. After Augustus' death in AD ;14, the Senate confirmed Tiberius as princeps and proclaimed him as

19320-447: The new augustus . Tiberius had already received imperium maius and tribunicia potestas in AD 4, becoming legally equal to Augustus but still subordinate to him in practice. The "imperial office" was thus not truly defined until the accession of Caligula , when all of Tiberius' powers were automatically transferred to him as a single, abstract position that was symbolized by his sacred title of augustus . The legal authority of

19488-418: The next morning, as reported by Lactantius, is not very clear: it closely resembles a Tau-Rho or a staurogram ( [REDACTED] ), a similar Christian symbol. That very day Constantine's army fought the forces of Maxentius and won the Battle of the Milvian Bridge (312), outside Rome . Eusebius of Caesarea (died in 339) gave two different accounts of the events. In his church history, written shortly after

19656-443: The now-destroyed archaeology and is used in describing and interpreting the site. Once artifacts and structures have been excavated, or collected from surface surveys, it is necessary to properly study them. This process is known as post-excavation analysis , and is usually the most time-consuming part of an archaeological investigation. It is not uncommon for final excavation reports for major sites to take years to be published. At

19824-529: The original research objectives of the archaeologists. It is then considered good practice for the information to be published so that it is available to other archaeologists and historians, although this is sometimes neglected. Before actually starting to dig in a location, remote sensing can be used to look where sites are located within a large area or provide more information about sites or regions. There are two types of remote sensing instruments—passive and active. Passive instruments detect natural energy that

19992-413: The past. Since its early development, various specific sub-disciplines of archaeology have developed, including maritime archaeology , feminist archaeology , and archaeoastronomy , and numerous different scientific techniques have been developed to aid archaeological investigation. Nonetheless, today, archaeologists face many problems, such as dealing with pseudoarchaeology , the looting of artifacts,

20160-698: The people who produced them, monetary value to collectors, or strong aesthetic appeal. Many people identify archaeology with the recovery of such aesthetic, religious, political, or economic treasures rather than with the reconstruction of past societies. This view is often espoused in works of popular fiction, such as Raiders of the Lost Ark, The Mummy, and King Solomon's Mines. When unrealistic subjects are treated more seriously, accusations of pseudoscience are invariably levelled at their proponents (see Pseudoarchaeology ) . However, these endeavours, real and fictional, are not representative of modern archaeology. There

20328-410: The powers of command where divided in consular imperium for Rome and proconsular imperium for the provinces . This division became obsolete in 19 BC, when Augustus was given consular imperium – despite leaving the consulship in 23 BC – and thus control over all troops. This overwhelming power was referred to as imperium maius to indicate its superiority to other holders of imperium , such as

20496-550: The precise locations of objects and features, known as their provenance or provenience, be recorded. This always involves determining their horizontal locations, and sometimes vertical position as well (also see Primary Laws of Archaeology ). Likewise, their association , or relationship with nearby objects and features , needs to be recorded for later analysis. This allows the archaeologist to deduce which artifacts and features were likely used together and which may be from different phases of activity. For example, excavation of

20664-448: The protectors of the Church. The territorial divisions of the Tetrarchy were maintained, and for most of the following century the Empire was ruled by two senior emperors, one in the West (with Milan and later Ravenna as capital) and another in the East (with Constantinople as capital). This division became permanent on the death of Theodosius I in 395, when he was succeeded by his sons Honorius and Arcadius . The two halves of

20832-440: The recognition of the Senate. Other "usurpers" controlled, if briefly, the city of Rome, such as Nepotianus and Priscus Attalus . In the East, the possession of Constantinople was the essential element of legitimacy, yet some figures such as Procopius are treated as usurpers. Rival emperors who later gained recognition are not always considered legitimate either; Vetranio had the formal recognition by Constantius II yet he

21000-406: The reverence of the emperor, making anything related to him sacer (sacred). He declared himself Jovius , the son of Jupiter , and his partner Maximian was declared Herculius , son of Hercules . This divine claim was maintained after the rise of Christianity, as emperors regarded themselves as the chosen rulers of God. The emperor no longer needed the Senate to ratify his powers, so he became

21168-459: The saying "Εν τούτῳ Νίκα!" ("In this, conquer!"). Not only Constantine, but the whole army saw the miracle. That night, Christ appeared to the Roman emperor in a dream and told him to make a replica of the sign he had seen in the sky, which would be a sure defence in battle. Eusebius wrote in the Vita that Constantine himself had told him this story "and confirmed it with oaths" late in life "when I

21336-436: The sole source of law. These new laws were no longer shared publicly and were often given directly to the praetorian prefects – originally the emperor's bodyguard, but now the head of the new praetorian prefectures – or with private officials. The emperor's personal court and administration traveled alongside him, which further made the Senate's role redundant. Consuls continued to be appointed each year, but by this point, it

21504-496: The specifically Christian idea that the emperor was God's chosen ruler on earth, a special protector and leader of the Christian Church, a position later termed Caesaropapism . In practice, an emperor's authority on Church matters was frequently subject to challenge. The Western Roman Empire collapsed in the late 5th century after multiple invasions by Germanic barbarian tribes, with no recognised claimant to Emperor of

21672-475: The sub-discipline of historical archaeology . For many literate cultures, such as Ancient Greece and Mesopotamia , their surviving records are often incomplete and biased to some extent. In many societies, literacy was restricted to the elite classes, such as the clergy , or the bureaucracy of court or temple. The literacy of aristocrats has sometimes been restricted to deeds and contracts. The interests and world-view of elites are often quite different from

21840-519: The temples of Šamaš the sun god, the warrior goddess Anunitu (both located in Sippar ), and the sanctuary that Naram-Sin built to the moon god, located in Harran , but he also had them restored to their former glory. He was also the first to date an archaeological artifact in his attempt to date Naram-Sin's temple during his search for it. Even though his estimate was inaccurate by about 1,500 years, it

22008-476: The term archaeology means "the study of ancient history". The discipline involves surveying , excavation , and eventually analysis of data collected, to learn more about the past. In broad scope, archaeology relies on cross-disciplinary research. Archaeology developed out of antiquarianism in Europe during the 19th century, and has since become a discipline practiced around the world. Archaeology has been used by nation-states to create particular visions of

22176-418: The title continued to be used for a time, with emperors registering the number of times they were hailed imperator . The title became the main appellation of the ruler by the time of Vespasian . After the Tetrarchy , emperors began to be addressed as dominus noster ("our Lord"), although imperator continued to be used. The appellation of dominus was known and rejected by Augustus, but ordinary men of

22344-485: The title of caesar . The Senate still exercised some power during this period, as evidenced by his decision to declare Nero a "public enemy", and did influence in the succession of emperors. Following the murder of Domitian in AD 96, the Senate declared Nerva , one of their own, as the new emperor. His "dynasty", the Antonine , continued the adoptive system until the reign of Marcus Aurelius (r. 161–180). Marcus

22512-473: The title of consul was Constans II , who was also the last Eastern emperor to visit Rome. It's possible that later emperors also used it as an honorary title, as the office of consul was not abolished until 892, during the reign of Leo VI . During the Dominate it became increasingly common for emperors to raise their children directly to augustus (emperor) instead of caesar (heir), probably because of

22680-418: The title was Junius Blaesus in AD 22, after which it became a title reserved solely for the sovereign. Augustus used Imperator instead of his first name ( praenomen ), becoming Imperator Caesar instead of Caesar Imperator . From this the title slowly became a synonym of the office, hence the word "emperor". Tiberius , Caligula and Claudius avoided using the title, but it is recorded that Caligula

22848-545: The title were Valentinian III and Marcian , in the 5th century. The only surviving document to directly refer to the emperor's power is the Lex de imperio Vespasiani , written shortly after Vespasian 's formal accession in December 69. The text, of which only the second part survives, states that Vespasian is allowed to: make treaties; hold sessions and propose motions to the Senate; hold extraordinary sessions with legislative power; endorse candidates in elections; expand

23016-559: The tradition of Chinese epigraphy by investigating, preserving, and analyzing ancient Chinese bronze inscriptions from the Shang and Zhou periods. In his book published in 1088, Shen Kuo criticized contemporary Chinese scholars for attributing ancient bronze vessels as creations of famous sages rather than artisan commoners, and for attempting to revive them for ritual use without discerning their original functionality and purpose of manufacture. Such antiquarian pursuits waned after

23184-409: The tribunes, such as sacrosanctity , since 36 BC. With this powers, he could veto any act or proposal of any magistrate, propose laws and convoke the Senate. His sacrosanctity also made him untouchable, and any offence against him could be treated as a crime of treason. The tribunician power was arguably the most stable and important of the emperor's powers. Despite being a perpetual title, it

23352-514: The triumph of Aemilius Paulus . It was a title held with great pride: Pompey was hailed imperator more than once, as was Sulla and Julius Caesar . However, as noted by Cassius Dio , the meaning of the title changed under the new monarchy, and came to denote "the possession of the supreme power". Both Dio and Suetonius refer to Caesar as the first one to assume imperator as a proper name (a praenomen imperatoris ), but this seems to be an anachronism . The last ordinary general to be awarded

23520-576: The use of metal detectors to be tantamount to treasure hunting, others deem them an effective tool in archaeological surveying. Examples of formal archaeological use of metal detectors include musketball distribution analysis on English Civil War battlefields, metal distribution analysis prior to excavation of a 19th-century ship wreck, and service cable location during evaluation. Metal detectorists have also contributed to archaeology where they have made detailed records of their results and refrained from raising artifacts from their archaeological context. In

23688-472: The usual term for one major branch of antiquarian activity. "Archaeology", from 1607 onward, initially meant what we would call "ancient history" generally, with the narrower modern sense first seen in 1837. However, it was Jacob Spon who, in 1685, offered one of the earliest definitions of "archaeologia" to describe the study of antiquities in which he was engaged, in the preface of a collection of transcriptions of Roman inscriptions which he had gleaned over

23856-507: The vague terms of "second" or "little emperor". Despite having a successful reign himself, Diocletian's tetrarchic system collapsed as soon as he retired in 305. Constantine I , the son of tetrarch Constantius I , reunited the empire in 324 and imposed the principle of hereditary succession which Diocletian intended to avoid. Constantine was also the first emperor to convert to Christianity , and emperors after him, especially after its officialization under Theodosius I , saw themselves as

24024-412: The years of his travels, entitled Miscellanea eruditae antiquitatis. Twelfth-century Indian scholar Kalhana 's writings involved recording of local traditions, examining manuscripts, inscriptions, coins and architectures, which is described as one of the earliest traces of archaeology. One of his notable work is called Rajatarangini which was completed in c.  1150 and is described as one of

24192-478: Was imperator , originally a military honorific, and caesar , originally a cognomen . Early emperors also used the title princeps ('first one') alongside other Republican titles, notably consul and pontifex maximus . The legitimacy of an emperor's rule depended on his control of the Roman army and recognition by the Senate ; an emperor would normally be proclaimed by his troops, or by

24360-674: Was Constantine XI Palaiologos , who died during the Fall of Constantinople to the Ottoman Empire in 1453. After conquering the city, Ottoman sultans adopted the title " Caesar of the Romans" ( kayser-i Rûm ). A Byzantine group of claimant emperors existed in the Empire of Trebizond until its conquest by the Ottomans in 1461, although they had used a modified title since 1282. Modern historians conventionally regard Augustus as

24528-415: Was Vitellius , who adopted the name Germanicus instead. Most emperors used it as their nomen – with Imperator as their praenomen – until the reign of Antoninus Pius , when it permanently became part of the formula Imperator Caesar [full name] Augustus . In the 3rd century, caesars also received the honorific of nobilissimus ("most noble"), which later evolved into a separate title. During

24696-525: Was a restlessly itinerant Italian humanist and antiquarian who came from a prominent family of merchants in Ancona , a maritime republic on the Adriatic . He was called by his contemporaries pater antiquitatis ('father of antiquity') and today "father of classical archaeology": "Cyriac of Ancona was the most enterprising and prolific recorder of Greek and Roman antiquities, particularly inscriptions, in

24864-421: Was also responsible for mentoring and training a whole generation of Egyptologists, including Howard Carter who went on to achieve fame with the discovery of the tomb of 14th-century BC pharaoh Tutankhamun . The first stratigraphic excavation to reach wide popularity with public was that of Hissarlik , on the site of ancient Troy , carried out by Heinrich Schliemann , Frank Calvert and Wilhelm Dörpfeld in

25032-508: Was also used to distinguish a junior co-emperor ( basileus ) from his senior colleague ( basileus autokrator ). By the times of the Palaiologos , there were two distinct ceremonies for the accession of an emperor: first an acclamation as basileus , and later a coronation as autokrator (which also included being raised on a shield). These rites could happen years apart. The Eastern Empire became not only an absolute monarchy but also

25200-512: Was always renewed each year, which often coincided with the beginning of a new regnal year (although " regnal years " were not officially adopted until Justinian I ). The office of censor was not fully absorbed into the imperial office until the reign of Domitian , who declared himself "perpetual censor" ( censor perpetuus ) in AD 85. Before this, the title had been only used by Claudius (47), Vespasian and Titus (both in 73). The emperor also had power over religious affairs, which led to

25368-446: Was an office often occupied by the emperor himself, who now had complete control over the bureaucratic apparatus. Diocletian did preserve some Republican traditions, such as the tribunicia potestas . The last known emperor to have used it was Anastasius I , at the start of the 6th century. Anastasius was also the last attested emperor to use the traditional titles of proconsul and pater patriae . The last attested emperor to use

25536-423: Was borrowed from the new geological and paleontological work of scholars like William Smith , James Hutton and Charles Lyell . The systematic application of stratigraphy to archaeology first took place with the excavations of prehistorical and Bronze Age sites. In the third and fourth decades of the 19th century, archaeologists like Jacques Boucher de Perthes and Christian Jürgensen Thomsen began to put

25704-401: Was by definition a plebeian , whereas Augustus, although born into a plebeian family, had become a patrician when he was adopted into the gens Julia . By adopting the role of a tribune, Augustus was presenting himself as the representative of the common man and the protector of democracy. As always, this was not a sudden grant of power; Augustus had been receiving several powers related to

25872-445: Was deemed worthy of his acquaintance and company." "Indeed", says Eusebius, "had anyone else told this story, it would not have been easy to accept it." Eusebius also left a description of the labarum , the military standard which incorporated the Chi-Rho sign, used by Emperor Constantine in his later wars against Licinius. An early visual representation of the connection between the Crucifixion of Jesus and his resurrection, seen in

26040-421: Was developed as a result of increasing commercial development. The purpose of archaeology is to learn more about past societies and the development of the human race . Over 99% of the development of humanity has occurred within prehistoric cultures, who did not make use of writing , thereby no written records exist for study purposes. Without such written sources, the only way to understand prehistoric societies

26208-419: Was hailed imperator by the Senate on his accession, indicating that it was already considered an integral part of the dignity. It was not until the late reign of Nero , in AD 66, that imperator became once more part of the emperor's nomenclature. Virtually all emperors after him used the praenomen imperatoris , with only a few variations under his successors Galba and Vitellius . The original meaning of

26376-426: Was no distinction between emperors and usurpers, as many emperors started as rebels and were retroactively recognized as legitimate. The Lex de imperio Vespasiani explicitly states that all of Vespasian's actions are considered legal even if they happened before his recognition by the Senate. Ultimately, "legitimacy was a post factum phenomenon." Theodor Mommsen famously argued that "here has probably never been

26544-618: Was not relevant in the early Empire, although emperors still attempted to maintain a familiar connection between them; Tiberius , for example, married Julia the Elder , making him Augustus ' son-in-law. Vespasian , who took power after the collapse of the Julio-Claudian dynasty and the tumultuous Year of the Four Emperors , was the first emperor to openly declare his sons, Titus and Domitian , as his sole heirs, giving them

26712-407: Was overthrown and expelled to Dalmatia in favor of Romulus, continued to claim the title until his murder in 480. The Eastern court recognized this claim and Odoacer minted coins in his name, although he never managed to exercise real power. The death of Nepos left Zeno as the sole emperor of a (technically) reunited Roman Empire. The Roman Empire survived in the East for another 1000 years, but

26880-412: Was proclaimed emperor at the age of 4. Many child emperors such as Philip II or Diadumenian never succeeded their fathers. These co-emperors all had the same honors as their senior counterpart, but they did not share the actual government, hence why junior co-emperors are usually not counted as real emperors by modern or ancient historians. There was no title to denote the "junior" emperor; writers used

27048-413: Was replaced with dominus ("lord"); the use of princeps and dominus broadly symbolizes the differences in the empire's government, giving rise to the era designations Principate and Dominate . The title is still found in some later sources, however. The poet Claudian , for example, describes Honorius as having been raised from " caesar " to " princeps " (instead of augustus ). The title survived

27216-617: Was reverted by the end of the century. Rome technically remained under imperial control , but was completely surrounded by the Lombards . Africa was lost to the Arabs in the early 7th century, and Rome eventually fell to the Lombards in 751, during the reign of Constantine V . The Frankish king Pepin the Short defeated them and received the favour of Pope Stephen II , who became the head of

27384-464: Was still a very good one considering the lack of accurate dating technology at the time. The science of archaeology (from Greek ἀρχαιολογία , archaiologia from ἀρχαῖος , arkhaios , "ancient" and -λογία , -logia , " -logy ") grew out of the older multi-disciplinary study known as antiquarianism . Antiquarians studied history with particular attention to ancient artifacts and manuscripts, as well as historical sites. Antiquarianism focused on

27552-486: Was the first emperor to actually use the title of "Roman emperor" (βασιλεύς Ῥωμαίων, Basileus Romaíon ). This was a response to the new line of emperors created by Charlemagne – although he was recognized as basileus of the Franks . By the 9th century the full imperial title became " basileus and autokrator of the Romans", usually translated as "Emperor and Autocrat of the Romans". The title autokrator

27720-409: Was the first emperor to rule alongside other emperors, first with his adoptive brother Lucius Verus , who succeeded jointly with him, and later with his son Commodus , who was proclaimed co- augustus in 177. Despite being the son of a previous emperor and having nominally shared government with him, Commodus' rule ended with his murder at the hands of his own soldiers. From his death in 192 until

27888-602: Was the real "usurper" (having been proclaimed by his troops). There were no true objective legal criteria for being acclaimed emperor beyond acceptance by the Roman army , which was really the true basis of imperial power. Common methods used by emperors to assert claims of legitimacy, such as support of the army, blood connections (sometimes fictitious) to past emperors, distributing one's own coins or statues, and claims to pre-eminent virtue through propaganda, were pursued just as well by many usurpers as they were by legitimate emperors. Septimius Severus notably declared himself as

28056-473: Was the ruler and monarchical head of state of the Roman Empire , starting with the granting of the title augustus to Octavian in 27 BC. The term emperor is a modern convention, and did not exist as such during the Empire. When a given Roman is described as becoming emperor in English, it generally reflects his accession as augustus , and later as basileus . Another title used

28224-408: Was the title used by early writers before the term imperator became popular. In his Res Gestae , Augustus explicitly refers to himself as the princeps senatus . The title was also sometimes given to heirs, in the form of princeps iuventutis ("first of the youth"), a term that continued to be used during the Tetrarchy . In the era of Diocletian and beyond, princeps fell into disuse and
