Agathodorus (Greek: Ἀγαθόδωρος) was an early Christian martyr in Pergamon, Asia Minor.
He was killed by the Romans to encourage his Christian masters to denounce their faith, but they refused and were also martyred.
The hagiographer Alban Butler wrote in his Lives of the fathers, martyrs, and other principal saints (1821),SS.
The martyrs suffered much in dungeons in both those cities, and underwent three severe examinations; in the third, to intimidate the masters, Agathodorus was, in their presence; scourged to death with bull’s sinews.
Some days after they were laid on iron spikes, their sides were again torn, and at length both were consumed by the flames, together with Agathonice, a sister of Papylus.
