St. Perpetua had just become a mother and St. Felicitas was on the point of becoming one, when they were thrown into prison at Carthage during the persecution of Severus. They prayed that they might become martyrs and were filled with joy at their condemnation. They were put to death in the amphitheatre in 202. They were the first saints to be included from outside Rome in the Roman Calendar of the Fourth Century. They are named in the Canon of the Mass.
