Saints Diodorus the presbyter and Marianus the deacon suffered martyrdom with Sts Chrysanthus and Daria.
In a cave near the place of execution, Christians began to gather to honor the anniversary of the saints’ martyrdom. They celebrated Church services and partook of the Holy Mysteries. Learning of this, the pagan authorities sealed the entrance to the cave, and those within received the crown of martyrdom.
Two of these martyrs are known by name: the Presbyter Diodorus and the Deacon Marianus.
