Barsumas (the Eutychian), an archimandrite of a Syrian monastery, who
warmly espoused the cause of Eutyches. When, in 448, Eutyches was denounced before
the local synod of Constantinople, Barsumas, who was resident in the city, raised
a violent opposition to the Eastern bishops. The next year, 449, at the "Robbers'
Synod" of Ephesus, Theodosius II. summoned Barsumas as the representative of the
malcontent monastic party, and granted him a seat and vote among the bishops. He
was the first monk allowed to act as a judge at a general council. Barsumas brought
with him a turbulent band of 1000 monks to coerce the assembly, and took a prominent
part in the disorderly proceedings, vociferously expressing his joy on the acquittal
of Eutyches and joining in the assault on the aged Flavian by the monks and soldiers.
The injuries inflicted were so serious that the venerable patriarch died three days
afterwards. When with great effrontery Barsumas presented himself at the council
of Chalcedon, 451, an outcry was raised against him as "the murderer of the blessed
Flavian." He actively propagated Eutychian doctrines in Syria and died 458. His
disciple, Samuel, carried Eutychianism into Armenia. He is regarded among the Jacobites
as a saint and worker of miracles (Assemani, Bibl. Orient. ii. 4; Labbe, iv.
105 seq.; Liberatus, c. 12; Tillemont, xv.; Schröckh, xvii. 451 seq.).
