Chronicle of Pseudo-Joshua the Stylite by Frank R. Trombley and John W. Watt, Liverpool University Press
Joshua Stylites (also Joshua the Stylite, or Pseudo-Joshua the Stylite), a resident of Edessa who may date to the sixth century CE, possibly later, wrote a narrative of the events in and around Edessa in the years 494/7–506/7, including the war between the Romans and Persians, usually known as the Chronicle of Joshua the Stylite.
This is a Syriac text written, in all probability, by an inhabitant of Edessa almost immediately after the conclusion of the war between Rome and Persia in 502-506 AD. Although that conflict is treated in other ancient texts, none of them can match ‘Joshua’ in his wealth of detail, his familiarity with the region where the hostilities occurred, and his proximity in time to the events. The Chronicle also vividly describes the famine and plague that swept through Edessa in the years immediately before the war. The work is a document of great importance for both the social and military history of late antiquity, remarkable for the information it provides on Roman and Persian empires alike.
Interpreting Catastrophe: Disasters in the Works of Pseudo-Joshua the Stylite, Socrates Scholasticus, Philostorgius, and Timothy Aelurus By
From: Journal of Late Antiquity Volume 2, Number 1, Spring 2009
pp. 79-98 | 10.1353/jla.0.0032
This study examines four different fifth- and early sixth-century Christian authors (Pseudo-Joshua, Socrates Scholasticus, Philostorgius, and Timothy Aelurus). It then analyzes the biblically derived interpretative structures that each uses to explain fifth-century political catastrophes such as the decline of western Roman political power. All of these authors incorporated a Christian explanation of disasters into a rhetorical strategy designed to advocate certain behaviors. Not all authors expected this rhetoric to influence behavior, but some, such as Pseudo-Joshua and Timothy Aelurus, believed that it could convince people to act in particular ways. The study concludes by arguing that, whereas late antique religious explanations of catastrophe often serve as a literary trope, they need not always be dismissed as empty or ineffectual rhetoric.
According to Encyclopaedia Britannica: Joshua the Stylite, an Edessan of unknown date who was a priest and a monk at the monastery of Zuqnīn near Amida.
