These were the guards of Saints Peter and Paul when they were kept in the Mamertime Prison in Rome. Along with forty-seven prisoners they were converted by Saint Peter. Since there was no water with which to baptize them, Saint Peter by his prayer caused to gush forth a miraculous spring which continues to flow to the present day. This lets us know that God will never fail to provide the water necessary for the sacrament of Baptism without which no one can enter Heaven. Saints Processus and Martinian were cruelly tortured and finally beheaded.
