Life and Martyrdom
By tradition Agrippina was a Roman by birth, of noble family, who rejected marriage and devoted her life entirely to the service of Christ as a consecrated virgin — the role closest to monastic life available in her era.
Her martyrdom is placed during the persecution of Christians under the emperor Valerian. Accounts relate that she voluntarily came forward before the authorities and openly confessed her Christian faith. She was subjected to severe torture, including beatings that broke her bones; though imprisoned in chains, she was, the tradition holds, delivered from her bonds. The injuries she sustained ultimately proved fatal, and she died a martyr.
