Baring-Gould’s sources: Roman Martyrology. Authority: — The Acts, not trustworthy."! Abundius was priest at Rome, and Abundantius was his deacon. They were brought before Diocletian, and ordered to adore Hercules. When they refused, they were sent chained to the Mamertine prison. But thirty other Christians, taken at the same time, were executed with the sword. After thirty days Abundius and Abundantius were brought again before Diocletian, and tortured; they remained inflexible in their faith, and were ordered to execution. On their way to martyrdom, they passed a man named Marcian, who was lamenting the death of his son John. Abundius and Abundantius bade the body be brought before them, and the father ran and fetched his dead boy, and laid him at the feet of the martyrs; and Abundius knelt down and prayed, and the eyes of the dead boy opened, and he revived. Then Marcian brought water, and Abundius baptized him and the boy. These were therefore arrested and executed the same day as Abundius and Abundantius.
