Their feast does not appear in the Roman calendar until the twelfth century. The Acts of these martyrs are wholly legendary. They give the following details. Marius was a Persian of noble extraction. With his wife, who was also noble-born, and his two sons, Audifax and Abachus, he came to Rome during the reign of Emperor Claudius II (268-270) to venerate the graves of the martyrs. They visited the Christians in prison, encouraged them by word and deed, and shared with them their goods. And like Tobias of old, they buried the bodies of the saints.
It was not long before they themselves were arrested; and when neither threats nor allurements could make them offer sacrifice to the idols, they were savagely flogged. Martha was the first to die, but not before she had fervently exhorted her husband and sons to endure steadfastly whatever tortures might be inflicted for the faith. All were beheaded in the same place and their bodies thrown into the fire. Felicitas, a saintly Roman woman, succeeded in recovering the half-burnt bodies and buried them on her estate.
