Avidius Cassius

Avidius Cassius was born around 130, in the town of Cyrrhus, Syria.[1][2][3] He was born to Gaius Avidius Heliodorus and Julia Cassia Alexandra. His father, Heliodorus, was of equestrian status, and served as Ab epistulis for Hadrian.[4] Heliodorus later served as Praefectus augustalis, the prefect of Roman Egypt, from 137 to 142 AD.[5][6] According to Cassius Dio, he received this post, which was one of the highest posts that an equestrian could hold, due to his oratory skills alone.[6] His mother, Julia Cassia, was the great-granddaughter of Junia Lepida, who was herself a great-great-granddaughter of the first Roman emperor, Augustus. She was also a descendant of Herod the Great, Ptolemy VI Philometor and Antiochus VIII Gryphus through her father, Gaius Julius Alexander Berenicianus.[5] Cassius was also a distant descendant of the Roman client-king Antiochus IV Epiphanes of Commagene, who had been dethroned half a century before.[2][7]

It is thought that Cassius began his career during the reign of Antoninus Pius.[8] He may have been adlected as a quaestor in 154.[9] It is thought that he became a legatus legionis of one of the legions stationed in Moesia Inferior, which guarded against the Sarmatians, during the late years of Pius' rule (138–161), and it is certain that he was a legatus by at least 161 AD, the last year of Pius' reign.[10][11]

Cassius rose to prominence rapidly c.164, under the co-emperors Lucius Verus and Marcus Aurelius, during the Parthian war of Lucius Verus, serving as legatus legionis or commander of Legio III Gallica.[2] In 165, he led Legio III Gallica down the Euphrates, and defeated the Parthians at Dura-Europos. Before the end of the year, Cassius and his legion marched to the south, crossed Mesopotamia at its narrowest point, and attacked and sacked the twin Parthian cities of the Tigris river: Seleucia, which was on the right bank; and Ctesiphon, which was on the left bank and was the Parthian capital.[12][13] After capturing Ctesiphon, he burnt the palace of Vologases IV. Despite the fact that Seleucia had surrendered to the Romans, he destroyed it as well, justifying it by claiming that the local population had broken their agreement.[12]

Cassius' legion was by this time in dire need of supplies. The first signs of what became known as the Antonine Plague showed up in his army in 165. Cassius marched back to Syria, carrying with him the spoils taken from his campaign. He sent details of his campaign to Rome, for which he was rewarded with elevation to the Senate. Much of his success was credited to Emperor Lucius Verus, who, although himself an excellent commander, was notedly unafraid of delegating military tasks to more competent generals.[14]

In May of 166, Cassius was made suffect consul, a position he held while still stationed outside of Rome.[15] During that year, Lucius Verus and Cassius launched a new campaign against the Parthians, invading across the northern stretch of the Tigris river, into Media. During this time, a false rumor reached Rome that Cassius had led Legio III Gallica across the Indus River.[16] In late 166 AD, Cassius was appointed imperial legate of Syria.[17]

In c.170, Cassius was given the extraordinary title of Rector Orientis (literally "Supreme Commander of the Orient"), giving him imperium over the entirety of the eastern section of the empire,[18] in order to combat a large rebellion in Egypt, commonly called the Bucolic War. This rebellion was centered in the area of the Pentapolis of Middle Egypt, and was motivated by a rapid rise of grain prices in the area. The Bucoli[lower-alpha 1] came close to capturing Alexandria, but were halted by Cassius' troops.[19] Cassius succeeded in putting down this revolt in 175, after using a strategy of dividing the various revolting tribespeople, and then conquering them.[20][21]

In 175, after hearing false reports that Marcus Aurelius had succumbed to his severe illness, Cassius declared himself emperor, claiming that Aurelius' troops in Pannonia, where he had been leading troops as a part of the Marcomannic War, had elected him emperor. Some versions say that Cassius was tricked, or persuaded, by Faustina the Younger, who was the wife of Aurelius, because she feared that Aurelius would die while Commodus, their son, was still young, a situation which would likely have led to a usurper seizing the throne for himself. According to these accounts, Faustina thus tricked, or persuaded, Cassius into rebelling, to ensure the next emperor was someone of her choosing.[18] The exact date of his revolt is unknown, although it is known that he revolted by at least 3 May, due to a document about his emperorship from that date. A papyrus from the Oxyrhynchus Papyri has shown that Cassius was confident of Egyptian support as early as April or even March.[4]

Aurelius attempted to suppress news of the revolt, but, when it became widespread throughout his camp, chose to address it in a speech. The exact wording of his speech is unknown, as the record given by Cassius Dio is believed to be a free composition, which followed only the outline of Aurelius' actual speech. In the record, Aurelius laments the betrayal of a dear friend, and says that if the danger had been to him alone, he would be willing to "set the issue" between himself and Cassius, before the Senate and the Army, and would have yielded the empire to Cassius, if the senate and army considered him the better leader.[4] He was also recorded as saying that he hoped that Cassius would not be killed or commit suicide, so that he could show mercy.[22] The Historia Augusta, a work both treasured by historians and notorious for its falsehoods, records that Aurelius formed a peace commission among his advisors.[4]

Cassius started the rebellion in a good position. He received large support from the Eastern provinces, especially his homeland of Syria, due to a combination of his distant royal descent, his victories in the Parthian War and the Bucolic War.[23] He received support from the provinces of Egypt, Syria, Syria Palaestina and Arabia Petraea, giving him a potential strength of seven legions: three from Syria, two from Syria Palaestina, one from Roman Arabia, and one from Egypt.[24][18][4] Cassius set his base of operations in Egypt,[24] with two important bases outside of Egypt being Antioch and Cyrrhus, both important military centres.[25] Gaius Calvisius Statianus, the contemporary prefect of Egypt, issued an edict, which has survived in a fragmentary state, ordering the populace of Egypt to rejoice at the accession of Cassius.[4]

Despite controlling some of the most important parts of the Roman East, especially Egypt which was a critical supplier of grain for the city of Rome, Cassius failed to win widespread support for his rebellion.[24] The Roman Senate swiftly declared Cassius a public enemy,[4] and Publius Martius Verus, the governor of Cappadocia, who staunchly opposed the rebellion, rallied public support for Aurelius.[4] Cassius, through the marriage of his daughter, Avidia Alexandra, to Titius Claudius Dryantianus Antonius, had connection to the Licinnii of Lycia, including Claudius Dryantianus's father Tiberius Claudius Agrippinus, who was a consul.[26][24] The aristocratic Licinnii are one of the most well known Lycian families.[27] It is unknown how much of a role Claudius Dryantianus played, although it is known that some considered him to be Cassius' partner in crime. Claudius Dryantianus and Avidia Alexandra were pardoned by Marcus Aurelius, although Claudius Dryantianus' estate was confiscated after his death.[28]

Many nobles throughout the empire opposed the rebellion, one example being Herodes Atticus, who is recorded as having sent Cassius a letter containing only the word emanes, literally "you are mad". Despite this widespread opposition, the capital of Rome was thrown into a panic, which forced Aurelius to send Gaius Vettius Sabinianus Julius Hospes, the governor of Pannonia Inferior, with troops to secure the city.[29] Aurelius was forced to withdraw from his campaign against the Iazyges, and end the Marcomannic War. Several barbarian tribes sent offers of their assistance to Aurelius, all of which were refused. Aurelius amassed troops and prepared to depart for the East, to depose Cassius.[30] It was soon clear that Aurelius was in a stronger position, with far more legions available to him than to Cassius.[31] When news of Aurelius' plans to invade reached Egypt, a centurion killed Cassius,[32] and sent his head to Aurelius, who refused to see it, and ordered it buried.[22] He was likely killed by at least the end of July 175, as Egypt chose to recognize Aurelius again on 28 July 175. Cassius had rebelled for three months and six days before being killed,[30] during which time no coins were struck bearing his image.[33]

Dio spoke highly of Cassius, saying that he was a "good man" whose only fault was that his father, Heliodorus, was given his post of Praefectus augustalis only because of his speaking abilities.[6] He was labelled as being a strict disciplinarian during his time as commander of Legio III Gallica.[24]

Cassius was married to Volusia Vettia Maeciana, daughter of Lucius Volusius Maecianus,[5] and had at least three children (the Historia Augusta implies he may have had more):[35]

• Avidius Heliodorus – first son of Cassius, who was banished by order of the emperor.[36]
• Avidius Maecianus – second son of Cassius, who was killed after the revolt had been put down.[36]
• Avidia Cassia Alexandra – daughter of Cassius, who was forced to live under the protection of an uncle, along with her husband, Titius Claudius Dryantianus Antonius.[36] Avidia and Claudius had four children.[37]
  • Claudius Cassius Agrippinus – he became a senator and was "ad honores admissus."[37]
  • Claudia Maeciana Alexandra.[37]
  • Claudia Dryantilla Platonis – one of the women who took part in the ludi saeculares of the year 204 AD. She married Cornelius Optatus (or Optatianus), who was either a consul or "adlectus inter consulares."[37]
  • Claudia Vettia Agrippina[37] – according to Christian Settipani her husband was Tiberius Claudius Themistocles Marathonius (fl. 150 AD), by whom she had a daughter:[38]
    • Claudia – wife of Claudius Capitolinus Bassus (fl. 180 AD), proconsul of Asia.[38] Her husband seems to have also been married to a Numeria Marcella.[lower-alpha 2][39][40] Claudia and Capitolinus Bassus had a daughter:[38][41][42]
      • Claudia Capitolina – described as theosebēs (pious) for contributing to the building of a synagogue, although it is not likely that she was Jewish herself, given her senatorial connections.[43][41][42] She married Titus Flavius Stasicles Metrophanes (fl. 190-199 AD), a senator in Rome and priest of Zeus Larasios in Tralleis. Her father-in-law was Titus Flavius Kleistosthenes, suffect consul between 220-230 AD.[41][43] She had the following issue:[lower-alpha 3][43][38]
        • Amnia Demetrias – wife of the senator Anicius Faustus (c. 240 – after 300), who was appointed consul in 298 AD.[38][40]
