(AFTER A.D. 680.)
[Roman Martyrology.]
S. Mansuetus is alluded to by many writers, but nothing of interest
connected with him has survived; except the fact that he was present
at the Roman Synod in 680, under S. Agatho, in which the heresy of the
Monothelites was condemned.
His relics are preserved in the Church of S. Stephen at Milan.
