Theophanes the Confessor, Bishop of Nicaea

Reading from the Synaxarion:

Saint Theophanes, the brother of Saint Theodore the Branded, was a
Palestinian by race. Both were monks at the Monastery of Saint Sabbas. They
were called "the Branded" because Theophilus, the last of the
Iconoclast emperors, had twelve iambic verses branded by hot irons on their
foreheads and then sent them into exile, where Theodore died in the year
838. After the death of Theophilus in 842, Theophanes was elected
Bishop of Nicaea. Both brothers composed many canons and hymns, thereby
adorning the services of the Church.

Apolytikion in the Plagal of the Fourth Tone
You are a guide of Orthodoxy, a teacher of piety and modesty, a
luminary of the world, the God inspired pride of monastics. O wise
Theophanes, you have enlightened everyone by your teachings. You are the harp
of the Spirit. Intercede to Christ our God for the salvation of our
souls.

Kontakion in the Fourth Tone
To the Church thou hast appeared like a new daystar, for thou dost
enlighten her with all thy doctrines' brilliant beams, O righteous Father
Theophanes, since thou indeed art a true priest of Christ our God.
