AGATHO.
POPE Agatho may deservedly be rank'd among Ecclesiastical Authors, because of the long Letter he writ to the Emperor Constantine, inserted in the Acts of the 6th Council; in * 1.1 which he does largely confute the Error of the Monothelites: But we ought not to value much another Letter, ascribed to this Pope, directed to Ethelred, King of the Mercians, to Theodorus of Canterbury, and to the Abbot Sexulphus; which seems to be a Supposititious Piece, made by some English Monk, and contains nothing remarkable. We shall speak of this Pope's first Letter, when we come to treat of the Acts of the 6th Council, and of another Letter written upon the same Subject and the same Occasion, by Datian, Bishop of Pavia, in the name of Mansuetus, Bishop of Milan, which is also among the Acts of this Council. This Pope died the 10th of January, in 682. after he had governed the Church of Rome 3 years, 6 Months, and 25 days.
