Santa Costanza is a 4th-century church in Rome , Italy, on the Via Nomentana , which runs north-east out of the city. It is a round building with well preserved original layout and mosaics. It has been built adjacent to a horseshoe-shaped church, now in ruins, which has been identified as the initial 4th-century cemeterial basilica of Saint Agnes . (Note that the much later Church of St Agnes , still standing nearby, is distinct from the older ruined one.) Santa Costanza and the old Saint Agnes were both constructed over the earlier catacombs in which Saint Agnes is believed to be buried.
154-503: According to the traditional view, Santa Costanza was built around the reign of Constantine I as a mausoleum for his daughter Constantina , later also known as Constantia or Costanza, who died in AD 354. However, more recent excavations have called this date (and therefore the original purpose of the building) into question. Ultimately, Constantina's sarcophagus was housed here, but it may have been moved from an earlier location. The mausoleum
308-642: A pivotal role in elevating the status of Christianity in Rome, decriminalizing Christian practice and ceasing Christian persecution in a period referred to as the Constantinian shift . This initiated the Christianization of the Roman Empire . Constantine is associated with the religiopolitical ideology known as Caesaropapism , which epitomizes the unity of church and state. He founded
462-568: A saint , she is traditionally credited for the conversion of her son. Constantine served with distinction under the Roman emperors Diocletian and Galerius . He began his career by campaigning in the eastern provinces (against the Persians ) before being recalled in the west (in AD ;305) to fight alongside his father in the province of Britannia . After his father's death in 306, Constantine
616-511: A Christian, he waited to be baptised on his deathbed, believing that the baptism would release him of any sins he committed in the course of carrying out his policies while emperor. He supported the Church financially, built basilicas, granted privileges to clergy (such as exemption from certain taxes), promoted Christians to high office, and returned property confiscated during the long period of persecution. His most famous building projects include
770-506: A collection of panegyrics from the late 3rd and early 4th centuries, provides valuable information on the politics and ideology of the tetrarchic period and the early life of Constantine. Contemporary architecture—such as the Arch of Constantine in Rome and palaces in Gamzigrad and Córdoba — epigraphic remains, and the coinage of the era complement the literary sources. Constantine
924-467: A connection to Bacchus , the God of Wine. This style of sarcophagus would cease to be used in Rome by the end of the fourth century, and this sarcophagus of Constantia is a prime example of the style. The sarcophagus is massive with the chest measuring 128 cm or 4 ft 2 3 ⁄ 8 in high, 233 cm or 7 ft 7 1 ⁄ 2 in long, and 157 cm or 5 ft 1 3 ⁄ 4 in wide. It
1078-536: A grand adventus in the city which was met with jubilation. Maxentius' body was fished out of the Tiber and decapitated, and his head was paraded through the streets for all to see. After the ceremonies, the disembodied head was sent to Carthage, and Carthage offered no further resistance. Unlike his predecessors, Constantine neglected to make the trip to the Capitoline Hill and perform customary sacrifices at
1232-550: A helmet emblazoned with the Chi Rho , and coins issued at Siscia in 317/318 repeat the image. The figure was otherwise rare and is uncommon in imperial iconography and propaganda before the 320s. It was not completely unknown, however, being an abbreviation of the Greek word chrēston (good), having previously appeared on the coins of Ptolemy III Euergetes in the 3rd century BC. Following Constantine, centuries of Christians invoked
1386-565: A large donative pledge to any who would support him as emperor, most of Constantine's army remained loyal to their emperor, and Maximian was soon compelled to leave. When Constantine heard of the rebellion, he abandoned his campaign against the Franks and marched his army up the Rhine. At Cabillunum ( Chalon-sur-Saône ), he moved his troops onto waiting boats to row down the slow waters of the Saône to
1540-468: A later date (though the bell tower dates from the 12th century). The structure itself, built in AD 305 as the Mausoleum of Diocletian , is the second oldest structure used by any Christian Cathedral. The cathedral was named after Saint Domnius ( Saint Dujam , or Saint Domnius ) patron saint of Split, who was a 3rd-century Bishop of Salona . Salona was a large Roman city serving as capital of
1694-487: A long evening of drinking, Galerius granted the request. Constantine's later propaganda describes how he fled the court in the night, before Galerius could change his mind. He rode from post-house to post-house at high speed, hamstringing every horse in his wake. By the time Galerius awoke the following morning, Constantine had fled too far to be caught. Constantine joined his father in Gaul , at Bononia ( Boulogne ) before

#17327730009371848-552: A mausoleum for Constantina's sister Helena in the reign of her husband Julian the Apostate . (This would be odd, however, because Julian was a staunch pagan.) If true, the larger of the two porphyry sarcophagi there would belong to Helena, and the smaller to Constantina, the opposite of what has been traditionally thought. The earlier triconch building of the 330s was probably indeed built for Constantina, but she later had to take second place to her sister. Then, as Constantina's fame as
2002-460: A military support, which Maxentius accepted. According to Eusebius, inter-regional travel became impossible, and there was military buildup everywhere. There was "not a place where people were not expecting the onset of hostilities every day". Constantine's advisers and generals cautioned against preemptive attack on Maxentius; even his soothsayers recommended against it, stating that the sacrifices had produced unfavourable omens. Constantine, with
2156-412: A new type of building. It was different from earlier styles in that the roof, which would previously have been typically flat and made with wood, was instead designed as a dome and vault. The mosaics of Santa Costanza are important examples of Early Christian art , and even rarer examples of secular palace ceiling mosaics. The apses , central dome, and ambulatory all had mosaic decoration, though that in
2310-541: A palace complex in the northeastern part of the city. To the south of his palace, he ordered the construction of a large formal audience hall and a massive imperial bathhouse. He sponsored many building projects throughout Gaul during his tenure as emperor of the West, especially in Augustodunum ( Autun ) and Arelate ( Arles ). According to Lactantius, Constantine followed a tolerant policy towards Christianity, although he

In these several biblical scenes appear, resembling catacomb paintings from the 3rd century, including Susanna and the Elders, Tobias, the sacrifice of Cain and Abel, the sacrifice of Elias on Mount Carmel, possibly Lot receiving the angels, Moses striking the rock for water, and possibly even Noah building
2618-453: A result of a debilitating sickness taken in the winter of 304–305, announced his resignation. In a parallel ceremony in Milan , Maximian did the same. Lactantius states that Galerius manipulated the weakened Diocletian into resigning and forced him to accept Galerius' allies in the imperial succession. According to Lactantius, the crowd listening to Diocletian's resignation speech believed, until
2772-518: A revolting and horrifying sight." Galerius died soon after the edict's proclamation, destroying what little remained of the Tetrarchy. Maximinus mobilised against Licinius and seized Asia Minor . A hasty peace was signed on a boat in the middle of the Bosphorus . While Constantine toured Britain and Gaul, Maxentius prepared for war. He fortified northern Italy and strengthened his support in
2926-511: A saintly figure developed in the Middle Ages, their roles became reversed in the popular mind. Constantine I Constantine I ( Latin : Flavius Valerius Constantinus ; 27 February c. 272 – 22 May 337), also known as Constantine the Great , was a Roman emperor from AD 306 to 337 and the first Roman emperor to convert to Christianity . He played
3080-550: A spirit that left a deep impression on his followers, inspiring some to believe that he had some form of supernatural guidance, ignored all these cautions. Early in the spring of 312, Constantine crossed the Cottian Alps with a quarter of his army, a force numbering about 40,000. The first town his army encountered was Segusium ( Susa , Italy), a heavily fortified town that shut its gates to him. Constantine ordered his men to set fire to its gates and scale its walls. He took
3234-460: A temple to Aphrodite . Generations later there was the story that a divine vision led Constantine to this spot, and an angel no one else could see led him on a circuit of the new walls. The capital would often be compared to the 'old' Rome as Nova Roma Constantinopolitana , the "New Rome of Constantinople". Constantine was the first emperor to stop the persecution of Christians and to legalize Christianity, along with all other religions/cults in

#17327730009373388-435: A tolerant and politically skilled man, Constantius advanced through the ranks, earning the governorship of Dalmatia from Emperor Diocletian, another of Aurelian's companions from Illyricum , in 284 or 285. Constantine's mother was Helena , a Greek woman of low social standing from Helenopolis of Bithynia . It is uncertain whether she was legally married to Constantius or merely his concubine . His main language
3542-415: A year, rejected it. Constantine sent Galerius an official notice of Constantius' death and his own acclamation. Along with the notice, he included a portrait of himself in the robes of an augustus. The portrait was wreathed in bay . He requested recognition as heir to his father's throne and passed off responsibility for his unlawful ascension on his army, claiming they had "forced it upon him". Galerius
3696-572: Is a complex of a church, formed from an Imperial Roman mausoleum , with a bell tower ; strictly the church is dedicated to the Virgin Mary , and the bell tower to Saint Domnius . Together they form the Cathedral of St. Domnius. The Cathedral of Saint Domnius , consecrated at the turn of the 7th century AD, is regarded as the oldest Catholic cathedral in the world that remains in use in its original structure, without near-complete renovation at
3850-450: Is clothed in golden robes, suggesting his power and supremacy. He is shown rising above paradise, which further shows his dominance over both heaven and earth. In the second apse, Christ appears somewhat more simply but still as supremely powerful. His robes are not quite as rich as in the other apse, but still suggest power. He wears a simple tunic but it is purple and gold. This suggests not only holy power, but human power given that purple
4004-544: Is located a minute's walk to the side of the Via Nomentana, a short way outside the ancient walls of Rome. The road follows the ancient Roman route which runs north-east from Rome to Nomentum or Mentana . The area was an Imperial family estate, and the bodies of the sisters were both brought considerable distances to be buried there: Ammianus records that Constantina's body was brought back from Bithynia , and Helena's from Gaul ( History XIV: 11, 6). The mausoleum
4158-474: Is made of porphyry , a hard purple stone, reserved by the Romans for use only by the imperial family, whose colour purple was. It was quarried from only one place, Mons Porphyriticus (Coptos, Egypt), making it even more exclusive. It appears, but can not be certain, that the sarcophagus of Constantina is a copy of that of Constantine I, her father, which is now lost. A piece of what is believed to be his sarcophagus
4312-496: Is missing from the decorative scheme is the mosaic of the central dome. In the sixteenth century, watercolours were made of this central dome so the pictorial scheme can be hypothetically reconstructed. The large porphyry sarcophagus of either Constantina or her sister Helena has survived intact, and is now in the Vatican Museum – an object of great significance to the study of the art of Late Antiquity. Santa Costanza
4466-632: Is my Rome ". Sirmium and Thessalonica were also considered. Eventually, however, Constantine decided to work on the Greek city of Byzantium , which offered the advantage of having already been extensively rebuilt on Roman patterns of urbanism during the preceding century by Septimius Severus and Caracalla , who had already acknowledged its strategic importance. The city was thus founded in 324, dedicated on 11 May 330 and renamed Constantinopolis ("Constantine's City" or Constantinople in English). Special commemorative coins were issued in 330 to honor
4620-472: Is not known. His praenomen is variously given as Lucius , Marcus and Gaius . Whatever the case, praenomina had already disappeared from most public records by this time. He also adopted the name "Valerius", the nomen of emperor Diocletian , following his father's ascension as caesar . Constantine probably spent little time with his father who was an officer in the Roman army, part of Emperor Aurelian 's imperial bodyguard. Being described as

These naturalistic ornaments suggest to

Despite the loss of the coloured stone veneers of the walls, some damage to the mosaics and incorrect restoration, the building stands in excellent condition as a prime example of Early Christian art and architecture . The vaults of the apses and ambulatory display well preserved examples of Late Roman mosaics. A key component which

An original structure might be located underneath the current church, as a possibly triconch -shaped structure was partially excavated in 1987 and 1992 and computer-reconstructed by David J. Stanley. That could suggest that the current church is the second Christian building on the site, and may be some decades later than traditionally thought, being built as
5236-499: Is similar in style and of the same material. A cast replica has been placed in the church, though in the ambulatory; presumably its original position was in the centre of the church, now occupied by the altar. There is another in the Museum of Roman Civilization in the city. Some consider that the building was only later reassigned as a church dedicated to Santa Costanza. The veneration of Constantina as "Santa Costanza" (Saint Constance)
5390-466: Is somewhat doubtful, the fact is that he seems to have been far less open in his support of Christianity than Constantine. Therefore, Licinius was prone to see the Church as a force more loyal to Constantine than to the Imperial system in general, as the explanation offered by the Church historian Sozomen . This dubious arrangement eventually became a challenge to Constantine in the West, climaxing in
5544-518: Is the anonymous Origo Constantini , a work of uncertain date which focuses on military and political events to the neglect of cultural and religious matters. Lactantius ' De mortibus persecutorum , a political Christian pamphlet on the reigns of Diocletian and the Tetrarchy , provides valuable but tendentious detail on Constantine's predecessors and early life. The ecclesiastical histories of Socrates , Sozomen , and Theodoret describe
5698-547: Is the color of royalty and the gold stripes suggestion a connection to the Roman emperors. Peter also approaches Christ in supplication, like one would approach the Emperor. This is one of the first examples in Christian art of Christ being portrayed in the same way as the emperor or royalty. It is a concept that would later be prevalent in Christian art and architecture. In this apse Christ is not just portrayed as royalty but as
5852-533: Is venerated as a saint in Eastern Christianity , and he did much to push Christianity towards the mainstream of Roman culture. The age of Constantine marked a distinct epoch in the history of the Roman Empire and a pivotal moment in the transition from classical antiquity to the Middle Ages . He built a new imperial residence in the city of Byzantium and renamed it New Rome , later adopting

The ambulatory has most of the surviving mosaics in the church. Larger arches mark the cardinal points in the mausoleum. The walls were probably covered in slabs of colourful marble, as was usual in imperial buildings. Santa Costanza was also to some extent

Maxentius' support continued to weaken: at chariot races on 27 October, the crowd openly taunted Maxentius, shouting that Constantine was invincible. Maxentius, no longer certain that he would emerge from a siege victorious, built a temporary boat bridge across the Tiber in preparation for a field battle against Constantine. On 28 October 312,

6468-505: The Church of the Holy Sepulchre and Old St. Peter's Basilica . In constructing the Old St. Peter's Basilica, Constantine went to great lengths to erect the basilica on top of St. Peter 's resting place, so much so that it even affected the design of the basilica, including the challenge of erecting it on the hill where St. Peter rested, making its complete construction time over 30 years from

However, he did visit the Senatorial Curia Julia , and he promised to restore its ancestral privileges and give it a secure role in his reformed government; there would be no revenge against Maxentius' supporters. In response, the Senate decreed him "title of the first name", which meant that his name would be listed first in all official documents, and they acclaimed him as "the greatest augustus". He issued decrees returning property that

His reputation flourished during the lifetime of his children and for centuries after his reign. The medieval church held him up as a paragon of virtue, while secular rulers invoked him as a prototype, a point of reference, and the symbol of imperial legitimacy and identity. At

The Roman army was reorganised to consist of mobile units ( comitatenses ), often around the Emperor, to serve on campaigns against external enemies or Roman rebels, and frontier-garrison troops ( limitanei ) which were capable of countering barbarian raids, but less and less capable, over time, of countering full-scale barbarian invasions . Constantine pursued successful campaigns against

The epitomes of Aurelius Victor ( De Caesaribus ), Eutropius ( Breviarium ), Festus ( Breviarium ), and the anonymous author of the Epitome de Caesaribus offer compressed secular political and military histories of the period. Although not Christian, the epitomes paint a favourable image of Constantine but omit reference to Constantine's religious policies. The Panegyrici Latini ,

His early support dissolved in the wake of heightened tax rates and depressed trade; riots broke out in Rome and Carthage ; and Domitius Alexander was able to briefly usurp his authority in Africa. By 312, he was a man barely tolerated, not one actively supported, even among Christian Italians. In

In contrast,

Constantine recognised the implicit danger in remaining at Galerius' court, where he was held as a virtual hostage. His career depended on being rescued by his father in the West.

In 288, Maximian appointed Constantius to serve as his praetorian prefect in Gaul . Constantius left Helena to marry Maximian's stepdaughter Theodora in 288 or 289. Diocletian divided the empire again in 293, appointing two caesars to rule over further subdivisions of East and West. Each would be subordinate to his respective augustus but would act with supreme authority in his assigned lands. This system would later be called

He completed the reconstruction of military bases begun under his father's rule, and he ordered the repair of the region's roadways.

The Franks learned of Constantine's acclamation and invaded Gaul across the lower Rhine over

The tombstones of the Imperial Horse Guard were ground up and used in a basilica on the Via Labicana , and their former base was redeveloped into the Lateran Basilica on 9 November 312—barely two weeks after Constantine captured the city. The Legio II Parthica was removed from Albano Laziale , and the remainder of Maxentius' armies were sent to do frontier duty on

In February 313, he met with Licinius in Milan and developed the Edict of Milan, which stated that Christians should be allowed to follow their faith without oppression. This removed penalties for professing Christianity, under which many had been martyred previously , and it returned confiscated Church property. The edict protected all religions from persecution, not only Christianity, allowing anyone to worship any deity that they chose. A similar edict had been issued in 311 by Galerius, senior emperor of

It was because of the predominance of this imagery that during the Renaissance period the building came to be known as the “Tempio di Bacco” and believed to have a pagan origin.

The pagan appearance of such images of grapes, fruit, birds, and mythological figures represent

The Edict of Milan included several clauses which stated that all confiscated churches would be returned, as well as other provisions for previously persecuted Christians. Some scholars think that Helena adopted Christianity as an adult, and according to Eusebius she was converted by Constantine, but other historians debate whether Constantine adopted his mother Helena's Christianity in his youth or whether he adopted it gradually over

According to Lactantius , Galerius was a brutal, animalistic man. Although he shared the paganism of Rome's aristocracy, he seemed to them an alien figure, a semi-barbarian. On 1 March, Constantius was promoted to the office of Caesar, and dispatched to Gaul to fight

Constantine's forces successfully surrounded the town and laid siege. Ruricius gave Constantine

The 4th-century mosaics on the ambulatory vault are contemporary with the building, and show a stark contrast to those in the apses, being essentially secular in appearance and make no obvious Christian allusions. The surface of area of many of these mosaic panels
10626-403: The ambulatory, filled with cupids, birds, and Bacchus and grapevines. This may reflect the merging of pagan and Christian values in Rome, or alternatively construction under the non-Christian Julian. These mosaics probably represent the sort of decoration found in the Imperial palaces of the period, and in general have needed little restoration. The mosaics of the central dome no longer exist, but

It is documented that Pope Nicholas I celebrated mass there in 865, the first time that "Santa Costanza" is recorded as its name, but its consecration as a church was not until 1254, by Pope Alexander IV , who had what were believed to be the remains of Constantia removed from
11088-558: The beginning of the Renaissance , there were more critical appraisals of his reign with the rediscovery of anti-Constantinian sources. Trends in modern and recent scholarship have attempted to balance the extremes of previous scholarship. Constantine was a ruler of major importance and has always been a controversial figure. The fluctuations in his reputation reflect the nature of the ancient sources for his reign. These are abundant and detailed, but they have been strongly influenced by

Eusebius describes a vision that Constantine had while marching at midday in which "he saw with his own eyes the trophy of a cross of light in the heavens, above the sun, and bearing the inscription, In Hoc Signo Vinces " ("In this sign thou shalt conquer"). In Eusebius's account, Constantine had a dream the following night in which Christ appeared with
11550-687: The city of Constantinople and made it the capital of the Empire, which remained so for over a millennium. Born in Naissus , in Dardania within Moesia Superior (now Niš , Serbia), Constantine was the son of Flavius Constantius , a Roman army officer of Illyrian origin who had been one of the four rulers of the Tetrarchy . His mother, Helena , was a Greek woman of low birth, probably from Asia Minor in modern Turkey . Later canonised as
11704-413: The coinage of Constantine advertised Mars as his patron. From 310 on, Mars was replaced by Sol Invictus , a god conventionally identified with Apollo. There is little reason to believe that either the dynastic connection or the divine vision are anything other than fiction, but their proclamation strengthened Constantine's claims to legitimacy and increased his popularity among the citizens of Gaul. By
11858-540: The columns while the "lower ring encloses a circular ambulatory whose space flows between the columns into the axial cylinder." This design essentially creates two spaces or two worlds, that of the ambulatory and that of the upper dome. The screens of the ambulatory and inner ring create a dark contrast to the bright upper space of the dome. This contrast of light can be seen in the picture of the main interior. The single door, flanked by two arched niches, would originally have been an internal arch or doorway leading straight into
12012-416: The composition using glass cubes that would become popular in later works. The use of color is significant as the mosaics encompass a narrow range of colors including dark green, brown, red and yellow on a relatively plain light backdrop. This color scheme is comparable to earlier Roman mosaic compositions of the first half of the fourth century and dates these compositions to very soon after the completion of
12166-465: The conflation of this with Christian art. A mosaic with two women wearing white, reported as being behind the sarcophagus in the Renaissance, has now gone and was never drawn. One of the apses shows a traditio legis : Christ is shown with Saints Peter and Paul giving Peter the scroll representing law, with the inscription, "DOMINUS PACEM DAT," or "The Lord is giving Peace." A few sheep represent his role as shepherd governing and leading his flock. Christ
12320-490: The course of his life. Constantine possibly retained the title of pontifex maximus which emperors bore as heads of the ancient Roman religion until Gratian renounced the title. According to Christian writers, Constantine was over 40 when he finally declared himself a Christian, making it clear that he owed his successes to the protection of the Christian High God alone. Despite these declarations of being
12474-633: The date Constantine ordered it to be built. Split Cathedral The Cathedral of Saint Domnius ( Croatian : Katedrala Svetog Duje ), known locally as the Sveti Dujam or colloquially Sveti Duje , is the Catholic cathedral in Split , Croatia . The cathedral is the seat of the Archdiocese of Split-Makarska , currently headed by Archbishop Zdenko Križić . The Cathedral of St. Domnius
12628-430: The demotion and continued to style himself as augustus on his coinage, even as other members of the Tetrarchy referred to him as a caesar on theirs. Maximinus was frustrated that he had been passed over for promotion while the newcomer Licinius had been raised to the office of augustus and demanded that Galerius promote him. Galerius offered to call both Maximinus and Constantine "sons of the augusti", but neither accepted
12782-438: The dome no longer survives. As evidenced by surviving Renaissance-era illustrations the church was likely once covered with mosaic decoration but today all that remains are those in the two apses and those in the ring barrel vault . In particular, the ring vault mosaics are well preserved and consist of eleven divisions of ornamental motifs, some of which are repeated. The mosaics here were composed using pieces of marble unlike
12936-487: The earlier rupture in their relations, Maxentius was eager to present himself as his father's devoted son after his death. He began minting coins with his father's deified image, proclaiming his desire to avenge Maximian's death. Constantine initially presented the suicide as an unfortunate family tragedy. By 311, however, he was spreading another version. According to this, after Constantine had pardoned him, Maximian planned to murder Constantine in his sleep. Fausta learned of
13090-408: The eastern front by the spring of 303, in time to witness the beginnings of Diocletian's " Great Persecution ", the most severe persecution of Christians in Roman history. In late 302, Diocletian and Galerius sent a messenger to the oracle of Apollo at Didyma with an inquiry about Christians. Constantine could recall his presence at the palace when the messenger returned and Diocletian accepted
13244-475: The ecclesiastic disputes of Constantine's later reign. Written during the reign of Theodosius II (r. 402–450), a century after Constantine's reign, these ecclesiastical historians obscure the events and theologies of the Constantinian period through misdirection, misrepresentation, and deliberate obscurity. The contemporary writings of the orthodox Christian Athanasius and the ecclesiastical history of
13398-400: The economy and the arts. His refusal to participate in the war increased his popularity among his people and strengthened his power base in the West. Maximian returned to Rome in the winter of 307–308 but soon fell out with his son. In early 308, after a failed attempt to usurp Maxentius' title, Maximian returned to Constantine's court. On 11 November 308, Galerius called a general council at
13552-522: The elder Emperor Maximian and needed a new source of legitimacy. In a speech delivered in Gaul on 25 July 310, the anonymous orator reveals a previously unknown dynastic connection to Claudius II , a 3rd-century emperor famed for defeating the Goths and restoring order to the empire. Breaking away from tetrarchic models, the speech emphasizes Constantine's ancestral prerogative to rule, rather than principles of imperial equality. The new ideology expressed in
13706-402: The emperor's traditional purple robes . Constantine accepted the decision, knowing that it would remove doubts as to his legitimacy. Constantine's share of the empire consisted of Britain, Gaul, and Spain, and he commanded one of the largest Roman armies which was stationed along the important Rhine frontier. He remained in Britain after his promotion to emperor, driving back the tribes of
13860-442: The empire. The document had special benefits for Christians, legalizing their religion and granting them restoration for all property seized during Diocletian's persecution. It repudiates past methods of religious coercion and used only general terms to refer to the divine sphere—"Divinity" and "Supreme Divinity", summa divinitas . The conference was cut short, however, when news reached Licinius that his rival Maximinus had crossed
14014-640: The event. The new city was protected by the relics of the True Cross , the Rod of Moses and other holy relics, though a cameo now at the Hermitage Museum also represented Constantine crowned by the tyche of the new city. The figures of old gods were either replaced or assimilated into a framework of Christian symbolism . Constantine built the new Church of the Holy Apostles on the site of
14168-402: The field bearing unfamiliar symbols on their standards and their shields. According to Lactantius "Constantine was directed in a dream to cause the heavenly sign to be delineated on the shields of his soldiers, and so to proceed to battle. He did as he had been commanded, and he marked on their shields the letter Χ, with a perpendicular line drawn through it and turned round thus at the top, being
14322-420: The first charge. His horse guards and praetorians initially held their position, but they broke under the force of a Constantinian cavalry charge; they also broke ranks and fled to the river. Maxentius rode with them and attempted to cross the bridge of boats ( Ponte Milvio ), but he was pushed into the Tiber and drowned by the mass of his fleeing soldiers. Constantine entered Rome on 29 October 312 and staged
14476-414: The great civil war of 324. Constantine's Christian eulogists present the war as a battle between Christianity and paganism; Licinius, aided by Gothic mercenaries, represented the past and ancient paganism, while Constantine and his Franks marched under the standard of the labarum . Outnumbered but fired by their zeal, Constantine's army emerged victorious in the Battle of Adrianople . Licinius fled across
14630-546: The honours that he had granted to leaders of the Senate were also invalidated. Constantine also attempted to remove Maxentius' influence on Rome's urban landscape. All structures built by him were rededicated to Constantine, including the Temple of Romulus and the Basilica of Maxentius . At the focal point of the basilica, a stone statue was erected of Constantine holding the Christian labarum in its hand. Its inscription bore
14784-404: The imperial court's demands for universal persecution. On 23 February 303, Diocletian ordered the destruction of Nicomedia' s new church, condemned its scriptures to the flames, and had its treasures seized. In the months that followed, churches and scriptures were destroyed, Christians were deprived of official ranks, and priests were imprisoned. It is unlikely that Constantine played any role in
14938-424: The larger sarcophagus and placed under a central altar. Santa Costanza is a circular, centralized structure, with a circular ambulatory ringing a high central space topped by a shallow dome, which is raised on a round drum , as can be seen from the exterior. It is built of brick-faced concrete and its structure is basically two rings supported by columns placed around a vertical central axis. The upper ring sits on
15092-403: The last moment, that Diocletian would choose Constantine and Maxentius (Maximian's son) as his successors. It was not to be: Constantius and Galerius were promoted to augusti , while Severus and Maximinus , Galerius' nephew, were appointed their caesars respectively. Constantine and Maxentius were ignored. Some of the ancient sources detail plots that Galerius made on Constantine's life in
15246-530: The message which the statue illustrated: "By this sign, Constantine had freed Rome from the yoke of the tyrant." Constantine also sought to upstage Maxentius' achievements. For example, the Circus Maximus was redeveloped so that its seating capacity was 25 times larger than that of Maxentius' racing complex on the Via Appia . Maxentius' strongest military supporters were neutralised when he disbanded
15400-524: The middle of 310, Galerius had become too ill to involve himself in imperial politics. His final act survives: a letter to provincials posted in Nicomedia on 30 April 311, proclaiming an end to the persecutions, and the resumption of religious toleration. Eusebius maintains "divine providence [...] took action against the perpetrator of these crimes" and gives a graphic account of Galerius' demise: "Without warning suppurative inflammation broke out round
15554-408: The middle of his genitals, then a deep-seated fistula ulcer; these ate their way incurably into his innermost bowels. From them came a teeming indescribable mass of worms, and a sickening smell was given off, for the whole of his hulking body, thanks to over eating, had been transformed even before his illness into a huge lump of flabby fat, which then decomposed and presented those who came near it with
15708-455: The military city of Carnuntum ( Petronell-Carnuntum , Austria) to resolve the instability in the western provinces. In attendance were Diocletian, briefly returned from retirement, Galerius, and Maximian. Maximian was forced to abdicate again and Constantine was again demoted to caesar. Licinius , one of Galerius' old military companions, was appointed augustus in the western regions. The new system did not last long: Constantine refused to accept
15862-419: The miraculous or the supernatural when justifying or describing their warfare. Constantine deployed his own forces along the whole length of Maxentius' line. He ordered his cavalry to charge, and they broke Maxentius' cavalry. He then sent his infantry against Maxentius' infantry, pushing many into the Tiber where they were slaughtered and drowned. The battle was brief, and Maxentius' troops were broken before
16016-420: The months following Diocletian's abdication. They assert that Galerius assigned Constantine to lead an advance unit in a cavalry charge through a swamp on the middle Danube, made him enter into single combat with a lion, and attempted to kill him in hunts and wars. Constantine always emerged victorious: the lion emerged from the contest in a poorer condition than Constantine; Constantine returned to Nicomedia from
16170-545: The name Constantinople after himself, where it was located in modern Istanbul . It subsequently became the capital of the empire for more than a thousand years, the later Eastern Roman Empire often being referred to in English as the Byzantine Empire , a term never used by the Empire, invented by German historian Hieronymus Wolf . His more immediate political legacy was that he replaced Diocletian's Tetrarchy with
16324-457: The natural scene, there are also four portraits including Constantia herself, "on the lid, four graceful portrait heads, one apparently that of Constantina, look calmly out over this assurance that the best is yet to be". The imagery presented of wine and nature are not inherently Christian but could be perceived as such considering the use of wine in the Eucharist . Or they could be perceived as
16478-431: The new title. By the spring of 310, Galerius was referring to both men as augusti. In 310, a dispossessed Maximian rebelled against Constantine while Constantine was away campaigning against the Franks. Maximian had been sent south to Arles with a contingent of Constantine's army, in preparation for any attacks by Maxentius in southern Gaul. He announced that Constantine was dead and took up the imperial purple. In spite of
16632-426: The north Italian plain sent Constantine embassies of congratulation for his victory. He moved on to Milan, where he was met with open gates and jubilant rejoicing. Constantine rested his army in Milan until mid-summer 312, when he moved on to Brixia ( Brescia ). Brescia's army was easily dispersed, and Constantine quickly advanced to Verona where a large Maxentian force was camped. Ruricius Pompeianus , general of
16786-596: The north without achieving great success. Constantius had become severely sick over the course of his reign and died on 25 July 306 in Eboracum . Before dying, he declared his support for raising Constantine to the rank of full Augustus. The Alamannic king Chrocus , a barbarian taken into service under Constantius, then proclaimed Constantine as augustus. The troops loyal to Constantius' memory followed him in acclamation. Gaul and Britain quickly accepted his rule; Hispania , which had been in his father's domain for less than
16940-522: The official propaganda of the period and are often one-sided; no contemporaneous histories or biographies dealing with his life and rule have survived. The nearest replacement is Eusebius 's Vita Constantini —a mixture of eulogy and hagiography written between 335 and circa 339 —that extols Constantine's moral and religious virtues. The Vita creates a contentiously positive image of Constantine, and modern historians have frequently challenged its reliability. The fullest secular life of Constantine
17094-520: The old family alliance between Maximian and Constantius and offer support to Maxentius' cause in Italy. Constantine accepted and married Fausta in Trier in summer 307. Constantine gave Maxentius his meagre support, offering Maxentius political recognition. Constantine remained aloof from the Italian conflict, however. Over the spring and summer of 307, he had left Gaul for Britain to avoid any involvement in
17248-491: The orator proclaims that Constantine experienced a divine vision of Apollo and Victory granting him laurel wreaths of health and a long reign. In the likeness of Apollo, Constantine recognised himself as the saving figure to whom would be granted "rule of the whole world", as the poet Virgil had once foretold. The oration's religious shift is paralleled by a similar shift in Constantine's coinage. In his early reign,
17402-545: The panegyrist the opportunity to comment favourably on the similarities between father and son, and Eusebius remarked that Constantine was a "renewal, as it were, in his own person, of his father's life and reign". Constantinian coinage, sculpture, and oratory also show a tendency for disdain towards the "barbarians" beyond the frontiers. He minted a coin issue after his victory over the Alemanni which depicts weeping and begging Alemannic tribesmen, "the Alemanni conquered" beneath
17556-422: The period of transition between paganism to Christianity that was taking place in Rome at this time. Bacchic motifs were often used in the funerary monuments of late antiquity and although a decided religious shift was taking place in Rome it would be logical that some traditional imagery would persist and be adopted by the new tradition. The theme continues in the floor mosaics which were similar in style to those in
17710-412: The persecution. In his later writings, he attempted to present himself as an opponent of Diocletian's "sanguinary edicts" against the "Worshippers of God", but nothing indicates that he opposed it effectively at the time. Although no contemporary Christian challenged Constantine for his inaction during the persecutions, it remained a political liability throughout his life. On 1 May 305, Diocletian, as
17864-642: The person or place to be honored" and was popular for mausoleums and places of baptisms at this time. Other early Christian buildings with a similar origin and a circular plan include Split Cathedral , built within Diocletian's Palace as his mausoleum, and the Rotunda of Galerius (now the Church of St. George) in Thessaloniki built as a mausoleum for Galerius . The huge funerary hall or Constantinian basilica gradually fell out of use and into ruins, with
18018-440: The phrase "Romans' rejoicing". There was little sympathy for these enemies; as his panegyrist declared, "It is a stupid clemency that spares the conquered foe." Following Galerius' recognition of Constantine as caesar, Constantine's portrait was brought to Rome, as was customary. Maxentius mocked the portrait's subject as the son of a harlot and lamented his own powerlessness. Maxentius, envious of Constantine's authority, seized
18172-475: The plot and warned Constantine, who put a eunuch in his own place in bed. Maximian was apprehended when he killed the eunuch and was offered suicide, which he accepted. Along with using propaganda, Constantine instituted a damnatio memoriae on Maximian, destroying all inscriptions referring to him and eliminating any public work bearing his image. The death of Maximian required a shift in Constantine's public image. He could no longer rely on his connection to
18326-492: The quicker waters of the Rhone . He disembarked at Lugdunum ( Lyon ). Maximian fled to Massilia ( Marseille ), a town better able to withstand a long siege than Arles. It made little difference, however, as loyal citizens opened the rear gates to Constantine. Maximian was captured and reproved for his crimes. Constantine granted some clemency but strongly encouraged his suicide. In July 310, Maximian hanged himself . In spite of
18480-512: The rebels Carausius and Allectus . In spite of meritocratic overtones, the Tetrarchy retained vestiges of hereditary privilege, and Constantine became the prime candidate for future appointment as Caesar as soon as his father took the position. Constantine went to the court of Diocletian, where he lived as his father's heir presumptive . Constantine received a formal education at Diocletian's court, where he learned Latin literature, Greek, and philosophy. The cultural environment in Nicomedia
18634-403: The ruler of the world, of all existence. He sits atop a blue sphere, a clear symbol for the world or universe. From this perch he hands keys to Peter. This is a clear sign of Christ, and the power of heaven, giving authority and holy power to man. It is also important to note that Peter was Rome's first bishop so this meant Roman authority was sanctioned by God. This concept and picture of Christ as
18788-451: The same heavenly sign and told him to make an army standard in the form of the labarum . Eusebius is vague about when and where these events took place, but it enters his narrative before the war begins against Maxentius. He describes the sign as Chi (Χ) traversed by Rho (Ρ) to form ☧, representing the first two letters of the Greek word ΧΡΙΣΤΟΣ (Christos). A medallion was issued at Ticinum in 315 which shows Constantine wearing
18942-461: The same time as the funerary hall. This was assumed to be the structure that survives. But excavations in 1992 discovered an earlier building beneath, and the existing building is now dated to around 350 AD. The structure of Santa Costanza reflects its original function as the mausoleum of one or both Constantine's two daughters, Constantia and Helena, rather than as the church it became much later. The centralized design put "direct physical emphasis on
19096-554: The same type of war he had waged against Severus and Galerius: he occupied Rome and prepared for a siege. He still controlled Rome's Praetorian Guard , was well-stocked with African grain, and was surrounded on all sides by the seemingly impregnable Aurelian Walls . He ordered all bridges across the Tiber cut, reportedly on the counsel of the gods, and left the rest of central Italy undefended; Constantine secured that region's support without challenge. Constantine progressed slowly along
19250-491: The sixth anniversary of his reign, he approached the keepers of the Sibylline Books for guidance. The keepers prophesied that, on that very day, "the enemy of the Romans" would die. Maxentius advanced north to meet Constantine in battle. Maxentius' forces were still twice the size of Constantine's, and he organised them in long lines facing the battle plain with their backs to the river. Constantine's army arrived on
19404-422: The slip and returned with a larger force to oppose Constantine. Constantine refused to let up on the siege and sent only a small force to oppose him. In the desperately fought encounter that followed, Ruricius was killed and his army destroyed. Verona surrendered soon afterwards, followed by Aquileia , Mutina ( Modena ), and Ravenna . The road to Rome was now wide open to Constantine. Maxentius prepared for
19558-434: The speech made Galerius and Maximian irrelevant to Constantine's right to rule. Indeed, the orator emphasizes ancestry to the exclusion of all other factors: "No chance agreement of men, nor some unexpected consequence of favour, made you emperor," the orator declares to Constantine. The oration also moves away from the religious ideology of the Tetrarchy, with its focus on twin dynasties of Jupiter and Hercules . Instead,
19712-513: The structure as opposed to being later additions. In the ambulatory wall there are two shallow apses, each with a mosaic showing Christ as the Pantocrator , the earliest surviving examples of this depiction; they probably date to the 5th or 7th century, though there has been much discussion of this. Like many mosaics of the period, both have suffered from restoration and both show elements of Roman imperial imagery, representing early examples of
19866-579: The summer of 305. From Bononia, they crossed the English Channel to Britain and made their way to Eboracum ( York ), capital of the province of Britannia Secunda and home to a large military base. Constantine was able to spend a year in northern Britain at his father's side, campaigning against the Picts beyond Hadrian's Wall in the summer and autumn. Constantius' campaign, like that of Septimius Severus before it, probably advanced far into
20020-581: The summer of 311, Maxentius mobilised against Constantine while Licinius was occupied with affairs in the East. He declared war on Constantine, vowing to avenge his father's "murder". To prevent Maxentius from forming an alliance against him with Licinius, Constantine forged his own alliance with Licinius over the winter of 311–312 and offered him his sister Constantia in marriage. Maximinus considered Constantine's arrangement with Licinius an affront to his authority. In response, he sent ambassadors to Rome, offering political recognition to Maxentius in exchange for
20174-580: The title of emperor on 28 October 306. Galerius refused to recognize him but failed to unseat him. Severus was sent against Maxentius in April 307, but during the campaign, Severus' armies, previously under command of Maxentius' father Maximian, defected, and Severus was seized and imprisoned. Maximian, brought out of retirement by his son's rebellion, left for Gaul to confer with Constantine. He offered to marry his daughter Fausta to Constantine and elevate him to augustan rank. In return, Constantine would reaffirm
20328-673: The town quickly. Constantine ordered his troops not to loot the town and advanced into northern Italy. At the approach to the west of the important city of Augusta Taurinorum ( Turin , Italy), Constantine met a large force of heavily armed Maxentian cavalry. In the ensuing Battle of Turin Constantine's army encircled Maxentius' cavalry, flanked them with his own cavalry, and dismounted them with blows from his soldiers' iron-tipped clubs. Constantine's armies emerged victorious. Turin refused to give refuge to Maxentius' retreating forces, opening its gates to Constantine instead. Other cities of
20482-809: The tribes on the Roman frontiers —such as the Franks , the Alemanni , the Goths , and the Sarmatians —and resettled territories abandoned by his predecessors during the Crisis of the Third Century with citizens of Roman culture. Although Constantine lived much of his life as a pagan and later as a catechumen , he began to favour Christianity beginning in 312, finally becoming a Christian and being baptised by Eusebius of Nicomedia , an Arian bishop, although
20636-404: The turn of the 4th century. On the intersection of two main roads, cardo and decumanus , there is a monumental court Peristyle , from which the only access to Cathedral of St. Domnius is to the east. The Cathedral of St. Domnius is composed of three different sections of different ages. The main part is Emperor Diocletian's mausoleum , which dates from the end of the 3rd century. The mausoleum
20790-445: The two augusti fought against one another at the Battle of Cibalae , with Constantine being victorious. They clashed again at the Battle of Mardia in 317 and agreed to a settlement in which Constantine's sons Crispus and Constantine II , and Licinius' son Licinius Junior were made caesars . After this arrangement, Constantine ruled the dioceses of Pannonia and Macedonia and took residence at Sirmium , whence he could wage war on
20944-542: The viewer ideas of beauty and abundance and reflect the decorations found in Early Christian catacombs , suggesting a theme of the promise of beauty and abundance to be found in Heaven following a Christian death. Significantly one particular panel is especially pagan in character and depicts grapevine scrolls accompanied by cupids picking grapes and crafting them into wine, a depiction that seems to recall Bacchus ,
21098-401: The winter of 306–307. He drove them back beyond the Rhine and captured kings Ascaric and Merogais ; the kings and their soldiers were fed to the beasts of Trier Amphitheater in the adventus (arrival) celebrations which followed. Constantine began a major expansion of Trier. He strengthened the circuit wall around the city with military towers and fortified gates, and he began building
21252-487: Was Latin , and during his public speeches he needed Greek translators. In April 286, Diocletian declared Maximian , another colleague from Illyricum, his co-emperor. Each emperor would have his own court, his own military and administrative faculties, and each would rule with a separate praetorian prefect as chief lieutenant. Maximian ruled in the West, from his capitals at Mediolanum ( Milan , Italy) or Augusta Treverorum ( Trier , Germany), while Diocletian ruled in
21406-404: Was a factor in the choice of location, although in general terms early Christians believed that their souls benefited from being buried close to martyrs, which was almost certainly a major attraction of the funerary hall to those who paid to be buried in it. Attaching an important mausoleum as an annex to a church was a common practice in Rome and can be seen the cases of other Roman churches such as
21560-554: Was actually Constantina's. Constantina's sarcophagus has complex symbolic designs in relief : "the surface is dominated by an intricate pattern of stylized vine-stems into which are fitted cherubs...with this scene of Dionysiac exuberance, and the hope of future blessedness which it implies, two peacocks, birds of immortality, are completely in accord". The scene presents an image of nature and plenty complete with grape vines, sheep and birds. The putti are framed in acanthus scrolls, above which there are several images of masks. Aside from
21714-576: Was born on 27 February, c. AD 272 in the city of Naissus , a time where the unity of the Empire was threatened by the breakaway wars of the Palmyrene Empire . The city—which is modern day Niš in Serbia —was located in Dardania within Moesia Superior . His father was Flavius Constantius an Illyrian who was born in the same region, and a native of the province of Moesia. His original full name, as well as that of his father,
21868-466: Was built like the rest of the palace with white local limestone and marble of high quality, most of which was from marble quarries on the island of Brač , with tuff taken from the nearby river Jadro beds, and with brick made in Salonitan and other factories. Later, in the 17th century a choir was added to the eastern side of the mausoleum. For that purpose the eastern wall of the mausoleum
22022-658: Was built on his orders at the claimed site of Jesus' tomb in Jerusalem and was deemed the holiest place in all of Christendom . The papal claim to temporal power in the High Middle Ages was based on the fabricated Donation of Constantine . He has historically been referred to as the "First Christian Emperor", but while he did favour the Christian Church, some modern scholars debate his beliefs and even his comprehension of Christianity. Nevertheless, he
22176-421: Was built over the catacombs that contained the relics of Saint Agnes, who was martyred as a thirteen-year-old, and which was attached to the ancient basilica of Saint Agnese mid-way along the liturgical north side. The basilica was originally a "funerary hall" rather than a church in the modern sense. Later legend considerably elaborated Constantina's devotion to Saint Agnes, but it now cannot be determined if this
22330-404: Was killed in 326. Thus Constantine became the sole emperor of the Roman Empire. Diocletian had chosen Nicomedia in the East as his capital during the Tetrarchy —not far from Byzantium, well situated to defend Thrace, Asia, and Egypt, all of which had required his military attention. Constantine had recognised the shift of the empire from the remote and depopulated West to the richer cities of
22484-439: Was lost under Maxentius, recalling political exiles, and releasing Maxentius' imprisoned opponents. An extensive propaganda campaign followed, during which Maxentius' image was purged from all public places. He was written up as a "tyrant" and set against an idealised image of Constantine the "liberator". Eusebius is the best representative of this strand of Constantinian propaganda. Maxentius' rescripts were declared invalid, and
22638-708: Was nonetheless a prominent member of the court: he fought for Diocletian and Galerius in Asia and served in a variety of tribunates ; he campaigned against barbarians on the Danube in 296 and fought the Persians under Diocletian in Syria in 297, as well as under Galerius in Mesopotamia in 298–299. By late 305, he had become a tribune of the first order, a tribunus ordinis primi . Constantine had returned to Nicomedia from
22792-528: Was not yet a Christian. He probably judged it a more sensible policy than open persecution and a way to distinguish himself from the "great persecutor" Galerius. He decreed a formal end to persecution and returned to Christians all that they had lost during them. Constantine was largely untried and had a hint of illegitimacy about him; he relied on his father's reputation in his early propaganda, which gave as much coverage to his father's deeds as to his. His military skill and building projects, however, soon gave
22946-474: Was open, fluid, and socially mobile; in it, Constantine could mix with intellectuals both pagan and Christian. He may have attended the lectures of Lactantius, a Christian scholar of Latin in the city.
