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.
