Just when you thought you were done with novenas (ha ha) here I am with St. Cyriacus. Although I don’t have an image of this dear saint, I do know that he was a Deacon who won the palm of martyrdom in the year 303 under Diocletian, along with two companions, Ss. Largus and Smaragdus (whom I’m including in this novena, firstly because their names were in the Collect for the Mass and secondly because, even if you’ve heard of St. Cyriacus [which would be really incredible] I doubt you’ve heard of Largus and Smaragdus, and since they accompanied Cyriacus to the death I think they certainly deserved to be honored and invoked alongside him in this novena. So there.)
St. Cyriacus is especially invoked for protection against sudden death.
O God, Who dost gladden us by the yearly festival of Thy holy Martyrs
Cyriacus, Largus, and Smaragdus: mercifully grant that we, who celebrate
their heavenly birthday, may also follow the example of the fortitude they showed in their martyrdom. Through our Lord Jesus Christ, Thy Son, who livest and reignest with Thee in the unity of the Holy Ghost, God, world without end. Amen.
