6th century) was an archdeacon and the author of an important history of the Nestorian and Monophysite controversies in the 5th- and 6th-century Christian Church.
In 535 he was sent to Rome, as legate of a great African national synod of two hundred and seventeen bishops, to consult Pope Agapetus I (535-6) about a number of questions (Harduin, II, 1154; Mansi, VIII, 808).
"Tired with the fatigue of traveling, and resting the mind a little from temporal cares" (according to the introduction to his book), he used his leisure to compose a summary history of the two great heresies of the preceding century.
His authorities are the Historia tripartita of Cassiodorus, acts of synods, and letters of contemporary Fathers.
In spite of Liberatus's controversial purpose and his indignation against Monophysites and all of those involved in the condemnation of the Three Chapters, his short history is well and fairly written.
