Constantine joined his father in Gaul , at Bononia ( Boulogne ) before

Of the four Tetrarchs, Constantius made the least effort to implement the decrees in the western provinces that were under his direct authority, limiting himself to knocking down a handful of churches. Eusebius denied that Constantius destroyed Christian buildings, but Lactantius records that he did. Between 303 and 305, Galerius began maneuvering to ensure that he would be in

He remained in Britain after his promotion to emperor, driving back the tribes of
10286-442: 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
10425-616: 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
10564-402: 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
10703-420: 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
10842-548: The forces of Allectus, resulting in the defeat and death of the usurper. Constantius in the meantime occupied Londinium ( London ), saving the city from an attack by Frankish mercenaries who were now roaming the province without a paymaster. Constantius massacred all of them. Constantius remained in Britannia for a few months, replaced most of Allectus's officers, and the British provinces were probably at this time subdivided along
10981-414: 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
11120-537: 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
11259-404: 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
11398-403: 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
11537-467: The lines of Diocletian's other administrative reforms of the Empire. The result was the division of Britannia Superior into Maxima Caesariensis and Britannia Prima , while Flavia Caesariensis and Britannia Secunda were carved out of Britannia Inferior . He also restored Hadrian's Wall and its forts. Later in 298, Constantius fought in the Battle of Lingones ( Langres ) against the Alemanni . He
11676-518: 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
11815-519: 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
11954-408: 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
12093-455: 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
12232-419: 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
12371-420: 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
12510-562: The monument to Constantine, the supposed son of Magnus Maximus and Elen, who was said to have ruled over the area prior to the Irish invasions . Constantine the Great 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
12649-482: 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
12788-421: The new caesar , and proclaimed Constantius as augustus . The same scene played out at Nicomedia ( İzmit ) under the authority of Diocletian. Constantius, notionally the senior emperor, ruled the western provinces, while Galerius took the eastern provinces. Constantine, disappointed in his hopes to become a caesar , fled the court of Galerius after Constantius had asked Galerius to release his son as Constantius
12927-431: 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
13066-479: The next three years the Rhine frontier continued to occupy Constantius's attention. From 303 – the beginning of the Diocletianic Persecution – Constantius began to enforce the imperial edicts dealing with the persecution of Christians , which ordered the destruction of churches . The campaign was avidly pursued by Galerius , who noticed that Constantius was well-disposed towards the Christians , and who saw it as
13205-501: The next two years neutralising the threat of the Franks who were the allies of Allectus, as northern Gaul remained under the control of the British usurper until at least 295. He also battled against the Alamanni , achieving some victories at the mouth of the Rhine in 295. Administrative concerns meant he made at least one trip to Italy during this time as well. Only when he felt ready (and only when Maximian finally came to relieve him at
13344-426: 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
13483-591: 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
13622-522: 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
13761-512: 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
13900-485: 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,
14039-540: 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
14178-640: The patron saints of Perugia, Italy Saint Constantius (Theban Legion) (c. 3rd century), a member of the legendary Theban Legion Constantius of Lyon ( fl. c. 480 ), cleric who wrote the Vita Germani , a hagiography Saint Constantius of Aquino , 6th century bishop of Aquino Saint Constantius of Capri (died 7th or 8th century), Bishop of Capri Other [ edit ] Constantius Africanus , ( c. 1020 – 1085), translator of Greek and Islamic medical texts See also [ edit ] Constantine Constantius ,
14317-412: 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
14456-440: 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
14595-475: 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
14734-488: 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
14873-458: The rank of tribunus within the army, and during the reign of Carus he was raised to the position of praeses , or governor, of the province of Dalmatia . It has been conjectured that he switched allegiances to support the claims of the future emperor Diocletian just before Diocletian defeated Carinus , the son of Carus, at the Battle of the Margus in July 285. In 286, Diocletian elevated
15012-447: The rank of caesar once Diocletian and Maximian had resigned the purple, by the end of 304 Galerius had convinced Diocletian (who in turn convinced Maximian) to appoint Galerius's nominees Severus and Maximinus as caesares . Diocletian and Maximian stepped down as co-emperors on 1 May 305, possibly due to Diocletian's poor health. Before the assembled armies at Mediolanum, Maximian removed his purple cloak and handed it to Severus,
15151-512: 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
15290-451: 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
15429-550: 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
15568-533: 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
15707-422: 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
15846-434: 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,
15985-464: 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
16124-581: 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
16263-576: 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
16402-667: 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
16541-681: 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
16680-445: 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
16819-401: 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
16958-487: 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
17097-490: Was also father of Constantine the Great , the first Christian emperor of Rome. The nickname "Chlorus" ( Ancient Greek : Χλωρός , lit. 'the Pale';) was first popularized by Byzantine -era historians and not used during the emperor's lifetime. Of humble origin, Constantius had a distinguished military career and rose to the top ranks of the army. Around 289, he set aside Helena , Constantine's mother, to marry
17236-564: 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,
17375-637: 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
17514-417: Was himself a Christian, although he pretended to be a pagan, and while Caesar under Diocletian, took no part in the Emperor's persecutions. It was claimed that his first wife, Helena , found the True Cross . Constantius's activities in Britain were remembered in medieval Welsh legend , which frequently confused his family with that of Magnus Maximus , who also was said to have wed a Saint Elen and sired
17653-446: Was ill. Constantine joined his father's court at the coast of Gaul, just as he was preparing to campaign in Britain. In 305, Constantius crossed over into Britain, travelled to the far north of the island and launched a military expedition against the Picts , claiming a victory against them and the title Britannicus Maximus II by 7 January 306. After retiring to Eboracum ( York ) for the winter, Constantius had planned to continue
17792-404: 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
17931-439: 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
18070-685: 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
18209-528: 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
18348-477: Was of humble origins. Constantine probably sought to dissociate his father's background from the memory of Maximian. Constantius was a member of the Protectores Augusti Nostri under the emperor Aurelian and fought in the east against the secessionist Palmyrene Empire . While the claim that he had been made a dux under the emperor Probus is probably a fabrication, he certainly attained
18487-417: 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. Because Diocletian did not completely trust Constantius—none of the Tetrarchs fully trusted their colleagues—Constantine was held as something of a hostage, a tool to ensure Constantius' best behavior. Constantine
18626-440: Was proclaimed as augustus (emperor) by his army at Eboracum ( York , England). He eventually emerged victorious in the civil wars against emperors Maxentius and Licinius to become the sole ruler of the Roman Empire by 324. Upon his ascension, Constantine enacted numerous reforms to strengthen the empire. He restructured the government, separating civil and military authorities. To combat inflation, he introduced
18765-476: Was proposed that a new Eastern capital should represent the integration of the East into the Roman Empire as a whole, as a centre of learning, prosperity, and cultural preservation for the whole of the Eastern Roman Empire. Among the various locations proposed for this alternative capital, Constantine appears to have toyed earlier with Serdica (present-day Sofia ), as he was reported saying that " Serdica
18904-445: Was put into a fury by the message; he almost set the portrait and messenger on fire. His advisers calmed him and argued that outright denial of Constantine's claims would mean certain war. Galerius was compelled to compromise: he granted Constantine the title "caesar" rather than "augustus" (the latter office went to Severus instead). Wishing to make it clear that he alone gave Constantine legitimacy, Galerius personally sent Constantine
19043-439: Was shut up in the city, but was relieved by his army after six hours and defeated the enemy. He defeated them again at Vindonissa thereby strengthening the defences of the Rhine frontier. In 300, he fought against the Franks on the Rhine frontier, and as part of his overall strategy to buttress the frontier, Constantius settled the Franks in the deserted parts of Gaul to repopulate the devastated areas. Nevertheless, over
19182-415: Was the son of Eutropius, a nobleman from the province of Moesia Superior , and Claudia , a niece of the emperors Claudius Gothicus and Quintillus . The same source also gives Claudius the nomina " Flavius Valerius " to strengthen his connection to Constantius. Modern historians suspect this maternal connection to be a genealogical fabrication created by his son Constantine I , and that his family
19321-404: Was to deal with the Roman usurper Carausius who had declared himself emperor in Britannia and northern Gaul in 286. In late 293, Constantius defeated the forces of Carausius in Gaul, capturing Bononia ( Boulogne-sur-Mer ). Carausius was then assassinated by his rationalis (finance officer) Allectus , who assumed command of the British provinces until his death in 296. Constantius spent
