Imperial Crisis Response and the Antiochene Magic and Treason Trials of 372 CE

Abstract

The writings of Ammianus Marcellinus, Libanius, and John Chrysostom have enshrined the Antiochene treason and magic investigations conducted under Emperor Valens in 372 CE as a testament to the ruler’s excessive paranoia and poor relationship with the eastern metropolis. By reexamining these three authors’ allegations of judicial corruption and abusive policing during the trials, this article contends that Valens’s response to the crisis was leveraged with far more legality, moderation, and success than often discussed. The rigorous tactics implemented during the trials demonstrate Valens and his administration’s intent to counter potential sedition among Antioch’s citizenry with the full brunt of Roman law and military action. Comparisons with legal precedents reveal, however, that Valens’s administration balanced these stern deterrents with deference to the law and attempted to assuage Antiochene interests throughout the investigations. Antiochene lobbying efforts were also more impactful in mitigating the imperial response, as demonstrated by Chrysostom’s account of a public protest that successfully petitioned Valens to pardon one of the accused. This article concludes that this pardon and Valens’s application of moderated or commuted sentences throughout the trials indicate his efforts to maintain a constructive imperial-urban relationship with the Antiochene populace. This conclusion not only forces a reconsideration of Valens’s relationship with his de facto imperial capital throughout the trials but also indicates the dangers of relying too heavily on literary interpretations of Valens’s reign.
