Liberatus (7) Diaconus, archdeacon of Carthage,
a Latin writer on the Nestorian and
Eutychian heresies, an account of which he
wrote entitled, Breviarium Causae Nestorianorum
et Eutychianorum, in which he records
some circumstances of his life. He visited
Rome in the pontificate of John II. on the
affair of the Acoemetae order of monks (c. 20).
In 535 he was deputed to Rome, with the
bps. Caius and Peter, by the council of
Carthage, to consult John II. as to how conforming
Arian bishops should be received.
They arrived about the time of the pope's
death (he was buried May 27, 535), and his
successor Agapetus (consecrated June 3, 535)
replied to the synod by the three envoys
(Mansi, viii. 849) Liberatus was an ardent
defender of the Three Chapters, and undertook
many journeys in that cause. On his return
home he composed his Breviarum, so named
as being an abridgment in 24 chapters of a
history which, beginning with the ordination
of Nestorius in 428, reached to the meeting of
the fifth synod in 553. The work was probably
written c. 560. Liberatus intimates in
his preface that he collected his materials from
the Ecclesiastical History which had been
recently translated from the Greek into Latin
(as Garnier thinks, the Historia Tripartitia of
Cassiodorus), from the Acts of the councils,
and from episcopal letters. The Breviarum was
ed. with copious notes and dissertations by
Garnier in 1675 (8vo, Paris), and this ed. is
reprinted by Migne (Patr. Lat. lxviii. 969).
Accounts of Liberatus will be found in Dupin
(Eccl. Wr. t. i. p. 558, ed. 1722), Ceillier (xi.
303), Cave (i. 527), Fabric. (Bibl. Lat. t. iv. p.
272, ed. Mansi, 1754).
