Cyriades (referred to in other sources as Mareades or Mariades or Mariadnes) was a Roman rebel who betrayed the city of Antioch to Shapur I sometime during the 250s. His chief claim to fame is that he is enumerated as one of the Thirty Tyrants who supposedly tried to overthrow the emperor Gallienus.
Cyriades is listed first in the catalogue of usurpers that comprise the chapter on the Thirty Tyrants within the notoriously unreliable Historia Augusta (and writing under the fictitious name of Trebellius Pollio), whose narrative is brief, indistinct, and largely inaccurate. According to this source, Cyriades was the son of a rich man, also named Cyriades, and whose debauched lifestyle offended his father. After stealing from his father, he fled to the Persians, stimulated Shapur I to invade the eastern Roman provinces and helped in the capture of Antioch and Caesarea. At this point he assumed the purple together with the title of Augustus, possibly killing his father before being slain by his own followers after a short, cruel and crime-filled reign. [1]
The Historia Augusta dates this as occurring when the emperor Valerian was on his way to the east to fight the Persians, so the traditional assumption is that the date of this rebellion was 259. Edward Gibbon instead dated the usurpation as occurring after the defeat and capture of Valerian in 260. [2]
The events of the Persian invasion of the east are also mentioned by other sources, but they attribute the fall of Antioch to the intrigues of an individual named Mareades or Mariades or Mariadnes, none of whom claimed the imperial dignity. [3]
Ammianus Marcellinus mentioned that during the attack on Antioch during the reign of Gallienus, "Mareades, who had inconsiderately brought the Persians there to the destruction of his own people, was burned alive." [4] Outside of the reference to Gallienus' reign, Ammianus Marcellinus does not date this event, but some scholars date this to 256. [5]
The Anonymous Continuator of Cassius Dio refers to a Mariadnes, and describes the same event, but with some variations. Firstly, the people of Antioch were aware of the upcoming invasion, and that a large part of the population of Antioch remained in the city, being well-disposed toward Mariadnes and also favouring a change from the Romans to the Persians. Since this part of the work immediately precedes a section on the approaching formal recognition of Aemilianus as Augustus in 253, its author set the event described therein in the early 250s. This date, and the fall of Antioch occurring during the reign of Trebonianus Gallus, is favoured by a number of modern scholars. [6]
Finally, according to John Malalas, during Valerian's reign, Mariades, one of the officials of Antioch, was expelled from the city council on charges of embezzlement. He was responsible for the running of the chariot races, had not bought the horses for one of the factions, and had stolen money that had been set aside for the Hippodrome. As a result, he fled to Persia, and in an interview with Shapur I, agreed to betray Antioch to the Persians. After the capture of the city, which was plundered and burnt to the ground, Shapur had Mariades beheaded as he was a traitor to his own people. [7] Although John Malalas dates this event to 265/6, his narrative also implies that it occurred around 252/3. [8]
It is now accepted that Cyriades and Mariades are one and the same person. [9] One possibility is that the name Cyriades is a Hellenized version of the Aramaic name Maryad'a ("My Lord Knows"), with CYRI the Latin transliteration of the Greek KYPI ("Lord"). This may give rise to the claim made in the Historia Augusta that Cyriades was firstly made Caesar and then Augustus, as KYPI could be used for the holder of either title. [10]
There is no numismatic and epigraphic evidence that Cyriades (or Mariades) was ever proclaimed Augustus. The coins published by Groltzius and Mediobarbus are rejected by numismatists as unquestionably spurious.
Constantius II was Roman emperor from 337 to 361. His reign saw constant warfare on the borders against the Sasanian Empire and Germanic peoples, while internally the Roman Empire went through repeated civil wars, court intrigues, and usurpations. His religious policies inflamed domestic conflicts that would continue after his death.
Publius Licinius Egnatius Gallienus was Roman emperor with his father Valerian from 253 to 260 and alone from 260 to 268. He ruled during the Crisis of the Third Century that nearly caused the collapse of the empire. He won numerous military victories against usurpers and Germanic tribes, but was unable to prevent the secession of important provinces. His 15-year reign was the longest in half a century.
Year 260 (CCLX) was a leap year starting on Sunday of the Julian calendar. At the time, it was known as the Year of the Consulship of Saecularis and Donatus. The denomination 260 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.
Valerian was Roman emperor from 253 to spring 260 AD. He persecuted Christians and was later taken captive by the Persian emperor Shapur I after the Battle of Edessa, becoming the first Roman emperor to be captured as a prisoner of war, causing shock and instability throughout the Roman Empire. The unprecedented event and the unknown fate of the captured emperor generated a variety of different reactions and "new narratives about the Roman Empire in diverse contexts".
Gaius Vibius Trebonianus Gallus was Roman emperor from June 251 to August 253, in a joint rule with his son Volusianus.
Marcus Aurelius Claudius Quintillus was a Roman emperor. He was a brother of Emperor Claudius Gothicus, whom he succeeded after Claudius' death in 270. Quintillus' claim to be emperor was challenged by Aurelian, who was proclaimed emperor by the legions he commanded. Quintillus' reign lasted no more than six months. Different sources report his cause of death as murder by his own soldiers, in battle with Aurelian, or by suicide.
Marcus Aurelius Marius was emperor of the Gallic Empire in 269 following the assassination of Postumus.
The Historia Augusta is a late Roman collection of biographies, written in Latin, of the Roman emperors, their junior colleagues, designated heirs and usurpers from 117 to 284. Supposedly modeled on the similar work of Suetonius, The Twelve Caesars, it presents itself as a compilation of works by six different authors, written during the reigns of Diocletian and Constantine I and addressed to those emperors or other important personages in Ancient Rome. The collection, as extant, comprises thirty biographies, most of which contain the life of a single emperor, but some include a group of two or more, grouped together merely because these emperors were either similar or contemporaneous.
Ingenuus was a Roman military commander, the imperial legate in Pannonia, who became a usurper to the throne of the emperor Gallienus when he led a brief and unsuccessful revolt in the year 260. Appointed by Gallienus himself, Ingenuus served him well by repulsing a Sarmatian invasion and securing the Pannonian border, at least temporarily. Ingenuus had also been charged with the military education of Caesar Cornelius Licinius Valerianus, the young son of Emperor Gallienus, but after the boy's death in 258, his position became perilous.
Fulvius Macrianus, also called Macrianus Major, was a Roman usurper. He was one of Valerian's fiscal officers. More precisely, sources refer to him as being in charge of the whole state accounts or, in the language of a later age, as Count of the Treasury and the person in charge of markets and provisions. It seems almost certain that he was an Equestrian. The Historia Augusta claims that he was the foremost of Valerian's military commanders, but that is most likely a gross exaggeration, if not entirely fictitious.
Titus Fulvius Junius Quietus was a Roman usurper against Roman Emperor Gallienus.
Lucius Mussius AemilianussignoAegippius who held a number of military and civilian positions during the middle of the third century. He is best known as a Roman usurper during the reign of Gallienus.
The Thirty Tyrants were a series of thirty rulers who appear in the Historia Augusta as having ostensibly been pretenders to the throne of the Roman Empire during the reign of the emperor Gallienus.
Titus Cornelius Celsus, supposedly a Roman usurper, who rebelled against Gallienus. He was one of the so-called Thirty Tyrants enumerated by Trebellius Pollio. His historicity is doubted by some scholars, who consider him an invention of the Historia Augusta.
Valens Thessalonicus was a Roman usurper during the reign of Emperor Gallienus.
Lucius Calpurnius Piso Frugi was probably a Roman general whom the imperial pretender Macrianus Major sent to suppress the governor of Achaia, Valens Thessalonicus. His existence is attested only by the unreliable Historia Augusta, which labels Piso as one of several usurpers who plagued the reign of Emperor Gallienus. While some historians grudgingly regard Piso as a historical figure, many reported details of his life, including his usurpation, are dismissed as fabrications.
Appius Claudius Censorinus was a fictitious usurper against Roman Emperor Claudius II, according to the unreliable Historia Augusta. He is included in the list of the Thirty Tyrants.
Victorinus Junior was a fictional usurper who was claimed to have risen up against the Roman Emperor Aurelian, according to the Historia Augusta. He is included in the list of the Thirty Tyrants.
Festus, whose name also appears in the manuscripts of his work as Rufus Festus, Ruffus Festus, Sextus Festus, Sextus Rufus, and Sextus, was a Late Roman historian and proconsul of Asia whose epitome Breviarium rerum gestarum populi Romani was commissioned by the emperor Valens in preparation for his war against Persia. It was completed about AD 370. The Breviarium covers the entire history of the Roman state from the foundation of the City until AD 364. The book consists of 30 chapters treating events in Roman history in terse overview, mainly focused on military and political conflicts. It is estimated as a work of very low quality.
Marcellus was an officer of the Roman Empire, supporter of usurper Procopius and briefly an usurper himself.
