Irmos: All things are filled with awe at thy divine glory; for thou, O Virgin who hast not known wedlock, didst contain within thy womb Him Who is God over all, and gavest birth to the timeless Son, granting peace unto all who hymn thee.
Theotokion: The Imperial City, having thee, the Queen and Lady, as a bulwark, doth triumph over the bestial assaults of the barbarians, is delivered from all perils, and groweth and is made steadfast, O most immaculate Mother of God
Thou wast shown to be a right wondrous martyr without shedding blood, a crowned one without enduring pangs, an excellent victor without being wounded, laying low hordes of the enemy by thy struggles, O blessed Diomedes.
Inextinguishable light shone forth upon thee, the righteous one, and gladness, its mate, followed thee, O divinely wise one, in that thou wast possessed of a righteous soul which followed all the precepts of the Savior.
The torturers who cut off thy head after thine end were struck blind; but having approached Christ with faith, their spiritual eyes were opened to radiant light, O wondrous Diomedes.
