Tetrarchs
The Tetrarchy was the system instituted by Roman emperor Diocletian in 293 AD to govern the ancient Roman Empire by dividing it between two emperors, the '' augusti'', and their juniors colleagues and designated successors, the ''caesares''. This marked the end of the Crisis of the Third Century. Initially Diocletian chose Maximian as his ''caesar'' in 285, raising him to co-''augustus'' the following year; Maximian was to govern the western provinces and Diocletian would administer the eastern ones. The role of the ''augustus'' was likened to Jupiter, while his ''caesar'' was akin to Jupiter's son Hercules. Galerius and Constantius were appointed ''caesares'' in March 293. Diocletian and Maximian retired on 1 May 305, raising Galerius and Constantius to the rank of ''augustus''. Their places as ''caesares'' were in turn taken by Valerius Severus and Maximinus Daza. The orderly system of two senior and two junior rulers endured until Constantius died in July 306, and his s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Portrait Of The Four Tetrarchs
The Portrait of the Four Tetrarchs is a porphyry sculpture group of four Roman emperors dating from around 300 AD. The sculptural group has been fixed to a corner of the façade of St Mark's Basilica in Venice, Italy since the Middle Ages. It probably formed part of the decorations of the Philadelphion in Constantinople, and was removed to Venice in 1204 or soon after. ''Spolia'' from the Fourth Crusade, the statues were originally designed as two separate sculptures, each consisting of a pair of armoured late Roman emperors embracing one another. The paired statues stand on plinths supported by a console of the same stone, and their backs are engaged in the remains of large porphyry columns to which the statues were once attached, carved all of a piece. The columns no longer exist, and one emperor pair is missing part of the plinth and an emperor's foot, which has been found in Istanbul. One statue pair has been sliced vertically and is missing a large portion of the right-ha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diocletian
Diocletian (; la, Gaius Aurelius Valerius Diocletianus, grc, Διοκλητιανός, Diokletianós; c. 242/245 – 311/312), nicknamed ''Iovius'', was Roman emperor from 284 until his abdication in 305. He was born Gaius Valerius Diocles to a family of low status in the Roman province of Dalmatia. Diocles rose through the ranks of the military early in his career, eventually becoming a cavalry commander for the army of Emperor Carus. After the deaths of Carus and his son Numerian on a campaign in Persia, Diocles was proclaimed emperor by the troops, taking the name Diocletianus. The title was also claimed by Carus's surviving son, Carinus, but Diocletian defeated him in the Battle of the Margus. Diocletian's reign stabilized the empire and ended the Crisis of the Third Century. He appointed fellow officer Maximian as ''Augustus'', co-emperor, in 286. Diocletian reigned in the Eastern Empire, and Maximian reigned in the Western Empire. Diocletian delegated further on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Gaius Galerius Valerius Maximianus (; 258 – May 311) was Roman emperor from 305 to 311. During his reign he campaigned, aided by Diocletian, against the Sasanian Empire, sacking their capital Ctesiphon in 299. He also campaigned across the Danube against the Carpi, defeating them in 297 and 300. Although he was a staunch opponent of Christianity, Galerius ended the Diocletianic Persecution when he issued an Edict of Toleration in Serdica in 311. Early life Galerius was born near Serdica, in Dacia Ripensis, later named Dacia Mediterranea, though some modern scholars consider the strategic site where he later built his palace named after his mother – Felix Romuliana ( Gamzigrad) – his birth and funeral place.Barnes, ''New Empire'', p. 37.

Porphyry (geology)
Porphyry ( ) is a textural term for an igneous rock consisting of coarse-grained crystals such as feldspar or quartz dispersed in a fine-grained silicate-rich, generally aphanitic matrix or groundmass. The larger crystals are called phenocrysts. In its non-geologic, traditional use, the term ''porphyry'' refers to the purple-red form of this stone, valued for its appearance. The term ''porphyry'' is from the Ancient Greek (), meaning "purple". Purple was the color of royalty, and the "imperial porphyry" was a deep purple igneous rock with large crystals of plagioclase. Some authors claimed the rock was the hardest known in antiquity. Thus, "imperial"-grade porphyry was prized for monuments and building projects in Imperial Rome and thereafter. Subsequently, the name was given to any igneous rocks with large crystals. The adjective ''porphyritic'' now refers to a certain texture of igneous rock regardless of its chemical and mineralogical composition. Its chief characteris ...

Philadelphion
The Philadelphion was a public square located in Constantinople. Location After passing the Forum of Theodosius, the Mese Odos (the main road of Constantinople) branched into two directions. One led to the quarter known today as Yedikule, via the Aksaray and Cerrahpaşa quarters. The other passed through the quarters of Şehzadebaşı and Fatih until reaching the quarter of Edirnekapı (formerly the Gate of Charisius). The space where the road forked was thought to be the physical centre, or ''mesomphalos'', of the city. History According to the 8th-century ''Parastaseis syntomoi chronikai'', the site of the later Philadelphion was originally known as the Proteichisma ("fore-wall"), and the site of a gate in the city wall built by Emperor Carus (r. 282–283). Raymond Janin suggested that this Proteichisma was an outer defensive wall protecting the wall erected by Septimius Severus (r. 193–211) during his rebuilding of Byzantium, possibly indicating that the city had a ...

Fall Of The Western Roman Empire
The fall of the Western Roman Empire (also called the fall of the Roman Empire or the fall of Ancient Rome, Rome) was the loss of central political control in the Western Roman Empire, a process in which the Empire failed to enforce its rule, and its vast territory was divided into several successor Polity, polities.

He was ''Caesar'' from 285 to 286, then ''Augustus'' from 286 to 305. He shared the latter title with his co-emperor and superior, Diocletian, whose political brain complemented Maximian's military brawn. Maximian established his residence at Trier but spent most of his time on campaign. In late 285, he suppressed rebels in Gaul known as the Bagaudae. From 285 to 288, he fought against Germanic tribes along the Rhine frontier. Together with Diocletian, he launched a scorched earth campaign deep into Alamannic territory in 288, refortifying the frontier. The man he appointed to police the Channel shores, Carausius, rebelled in 286, causing the secession of Britain and northwestern Gaul. Maximian failed to oust Carausius, and his invasion fleet was destroyed by storms in 289 or 290. Maximian's subordinate, Constantius, campaigned against Ca ...

Constantius Chlorus
Flavius Valerius Constantius "Chlorus" ( – 25 July 306), also called Constantius I, was Roman emperor from 305 to 306. He was one of the four original members of the Tetrarchy established by Diocletian, first serving as caesar from 293 to 305 and then ruling as augustus until his death. Constantius was also father of Constantine the Great, the first Christian emperor of Rome. The nickname Chlorus () was first popularized by Byzantine-era historians and not used during the emperor's lifetime. After his re-conquering of Roman Britain, he was given the title 'Redditor Lucis Aeternae', meaning 'The Restorer of Eternal Light'. Of humble origin, Constantius had a distinguished military career and rose to the top ranks of the army.

Licinius
Valerius Licinianus Licinius (c. 265 – 325) was Roman emperor from 308 to 324.

He was finally defeated at the Battle of Chrysopolis (AD 324), and was later executed on the orders of Constantine I. Early reign Born to a Dacian peasant family in Moesia Superior, Licinius accompanied his close childhood friend, the future emperor Galerius, on the Persian expedition in 298. He was trusted enough by Galerius that in 307 he was sent as an envoy to Maxentius in Italy to attempt to reach some agreement about the latter's illegitimate political position. Galerius then trusted the eastern provinces to Licinius when he went to deal with Maxentius personally after the death of Severus II. Upon his return to the east Galerius elevated Licinius to the rank of ''Augustus'' in the West on 11 Novem ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Maxentius
Marcus Aurelius Valerius Maxentius (c. 283 – 28 October 312) was a Roman emperor, who reigned from 306 until his death in 312.
