Holy Martyrs Chrysanthus and Daria and with them Martyrs Claudius the Tribune with his wife Hilaria and their sons Jason and Maurus, and Diodorus the Priest and Marianus the Deacon at Rome

According to their Passion, Chrysanthus was the son of Polemius, a nobleman from Alexandria who became a senator in Rome. As a student of philosophy he found the books of the New Testament, sought out a hidden priest, Carpophorus, and was baptized. His father tried prison and then pleasure to turn him back, and finally married him to Daria, a learned priestess of Athena. Chrysanthus won her over, and they lived as brother and sister, gathering communities of young men and women.

Arrested under Numerian, they converted the tribune Claudius, his wife Hilaria and their sons Jason and Maurus, who were all put to death. Chrysanthus and Daria were buried alive in a pit by the Via Salaria, c. 283. Later the priest Diodorus, the deacon Marianus and other Christians praying at their tomb were walled up in the cave.
