Zosimus (historian) in the context of "Fausta"

Pacatianus, known in English as Pacatian (/ˈpəkeɪʃ(i)ən/; Latin: Tiberius Claudius Mar[...] Pacatianus; died c. 248) was a usurper in the Danube area of the Roman Empire during the time of Philip the Arab. His praenomen and nomen suggest his ancestors obtained Roman citizenship either during the time of Tiberius or of Claudius.

His life is known from mentions in the histories of Zosimus and Zonaras. However, the chronology of these accounts is obscure, and modern scholars use coinage to establish the timeline of his life and revolt. Zonaras names him as a 'unit commander' of one of the Danube legions, possibly Legio VII Claudia. He was likely a leader in the effort to drive Gothic invaders out of Roman territory in 248, one of the first actions of the Gothic War. Either during this action or soon after he was acclaimed emperor by the Danube legions. Eventually his control extended to the city of Viminacium. According to Zosimus, the news of Pacatian's revolt in Moesia and of Jotapian's near-simultaneous revolt in Syria prompted Philip to make an offer to the Roman Senate to step down. Both Zosimus and Zonoras relate that Philip was advised by the senator Decius, who predicted that Pacatian would soon be killed by his troops. This soon came to pass, and Philip (over Decius' objections) sent Decius to the Danube to find out the causes of the revolt. Decius was promptly acclaimed as emperor by the legions on the Danube, and (though Zonaras records that Decius offered to resign) eventually overcame Philip by the end of 249.

Lucius Domitius Alexander (died c. 310), probably born in Phrygia, was vicarius of Africa when Emperor Maxentius ordered him to send his son as hostage to Rome. Alexander refused and proclaimed himself emperor in 308.

The most detailed if somewhat confusing description of the insurrection is given by Zosimus (II, 12 and 14). He reports that Maxentius sent his portrait to Africa to gain recognition as Emperor there. The troops resisted because of their loyalty to Galerius. Maxentius ordered Domitius Alexander, the vicar of Africa, to send his son to Rome to secure his loyalty. Alexander refused and was crowned Emperor by his army. The incident was probably caused by the conflict between Maxentius and his father Maximian in April 308, and Zosimos confused Galerius with Maximian in his account.

Jotapian (/dʒəˈteɪpiən/) or Iotapian (Latin: M(arcus) F(ulvius) Ru(fus) Iotapianus; died c. 249) was an usurper in the eastern provinces of the Roman Empire during the reign of Emperor Philip the Arab, around 249. Jotapian is known from his rare coins and from accounts in Aurelius Victor (Caesares xxix.2), Zosimus (i.20.2 and i.21.2), and Polemius Silvius (Laterculus).
