Thou didst shine resplendently, Martyr Tatiana, in thy sacred sufferings and in the crimson of thy blood, soaring to Heaven like a fair dove; hence ever pray Christ for all them that honour thee.

Tatiana the Martyr of Rome

Reading from the Synaxarion:

Saint Tatiana was the daughter of a most distinguished consul of Rome.
She became a deaconess of the Church, and for her confession of the
Faith of Christ, she endured many torments. As she was suffering,
angels punished her tormentors with the same torments they inflicted on
her, until they cried out that they could no longer endure the
scourges invisibly brought upon them. She was beheaded during the reign
of Alexander Severus (111-135).

Apolytikion in the Fourth Tone
O Lord Jesus, unto Thee Thy lamb doth cry with a great voice: O my
Bridegroom, Thee I love; and seeking Thee, I now contest, and with Thy
baptism am crucified and buried. I suffer for Thy sake, that I may reign
with Thee; for Thy sake I die, that I may live in Thee: accept me
offered out of longing to Thee as a spotless sacrifice. Lord, save our
souls through her intercessions, since Thou art great in mercy.

Kontakion in the Fourth Tone
Thou didst shine resplendently, Martyr Tatiana, in thy sacred
sufferings and in the crimson of thy blood, soaring to Heaven like a fair
dove; hence ever pray Christ for all them that honour thee.
