Antioch, in 429 he was
quaestor sacri palatii when Emperor
Theodosius II (r. 402–450) appointed him member of the first commission that was to formulate the
Codex Theodosianus (March 26). Later he was appointed
praetorian prefect of the East, an office he held between 430 and 431. During his tenure, he exchanged letters with
Theodoret, organised with
Nestorius his return to the East through
Asia Minor and
Pontus, and rebuilt the city walls of
Antioch. In 431 he was appointed consul by the Eastern court, with
Anicius Auchenius Bassus as Western colleague. In 435 he was appointed member of the second commission for the formulation of the
Codex Theodosianus. When the Codex was issued in 438, Antiochus was listed among its formulators. He died between 438 and 444. ==References and sources==
