Martyr Cyril the Deacon and Those with him
Saint Cyril was a deacon from Heliopolis in Phoenicia. During the reign of the Emperor Constantius, son of Saint Constantine, he had also broken the idols in pieces. When Julian came to power, Saint Cyril was seized by the idolaters and his belly was ripped open. The other holy Martyrs celebrated today, martyred in Gaza and Ascalon during the reign of Julian, were men of priestly rank and consecrated virgins; they were disemboweled, filled with barley, and set before swine to be eaten. The account of all the above Saints is given in Book III, ch. 3, of Theodoret of Cyrrhus' "Ecclesiastical History."
Apolytikion of Martyr Cyril the Deacon & Companions
Plagal of the Fourth Tone
Since they had slain through their abstinence and struggles the fiery ragings and fierce motions of the passions, the staunch Martyrs of Christ God laid hold on the graces to drive off the pains and illnesses of the sick and work wonders both while living and after death. Strange indeed is the miracle! That these bare bones should pour forth such overflowing streams of cures. Glory be to our only God.
