Confession and Arrest
The governor of the district discovered that Carpus and Papylus were not celebrating the pagan festivals. The officials had them arrested and tried to persuade them to take up Roman pagan worship. The saints refused, declaring that they would not sacrifice to false gods.
According to the Latin and Greek acts, the immediate charge was their refusal to eat meat offered to idols and to sacrifice to the gods in the name of the emperor. The accounts name a Roman governor (given as Pergamos) and a member of his council (Optimus).
Martyrdom
The judge ordered the prisoners shackled in iron chains and paraded through the city, then bound to horses and dragged toward the neighboring city of Sardis. Agathodorus and Agathonica followed after Carpus and Papylus of their own will, showing their own commitment to the Christian faith.
The accounts describe distinct fates. By one account Agathonica was put to death with ox sinews, while Carpus, Papylus, and Agathodorus were beheaded at Sardis. The surviving acts vary: in them Agathodorus is scourged to death with bull's sinews; Carpus is hanged and clawed alive; and the death of Agathonica is told differently in the two recensions — the Greek version relates that she threw herself into a blazing pyre after witnessing Carpus's death, while the Latin version states she was hanged and burned.
Saint Papylus was known during his lifetime for the gift of curing the sick; after his martyrdom the faithful attributed continued healing through his intercession in prayer.
Sources and Historical Debate
The early historian Eusebius preserved an account of these martyrs. Only Greek and Latin manuscript versions survive; the Latin is longer and more detailed than Eusebius's Greek text, and the Greek version notes that the account of Agathonica was reported from a letter written by Christians.
The manuscript traditions differ on the saints' identities. One account identifies Carpus as a bishop from Gurdos in Lydia and Papylus as a deacon from Thyatira — a wealthy Roman citizen and the brother of Agathonica.
Scholars are divided on the date: some assign the events to the reign of Marcus Aurelius in the second century, while others, following the qualities of the Latin version, argue for the persecution under Decius in the third century. The anchor tradition followed here places the martyrdom under Decius.
