Evagrius was born in the Syrian city of Epiphania into a wealthy family that could support the extended legal study necessary to qualify as a scholasticus. This education enabled him to pursue a career in the patriarchate of Antioch, where he ended up as legal advisor to the Chalcedonian Patriarch, Gregory I, whom he helped to rebut an accusation of sexual misconduct. He is known for composing an Ecclesiastical History, which continued the work of Socrates Scholasticus, and to a lesser extent those of Sozomen and Theodoret, and is the last classical example of this genre. He also compiled a collection of documents, speeches, and other material issued by Gregory and a work celebrating the birth of Emperor Maurice’s son Theodosius in 584, neither of which survives. Emperor Tiberius had awarded him the honorary rank of quaestor in return for a literary work, and Maurice that of prefect, probably for the work on Theodosius (6.24).
