Juliana of Nicomedia & her 630 Companion Martyrs

Reading from the Synaxarion:

Saint Juliana, who was from Nicomedia, lived during the years of
Maximian and was the daughter of wealthy parents. They were pagans, but
she was secretly a Christian. Without consulting her, her parents
betrothed her to an idolater named Eleusius, who was a member of the
Senate. She, not wishing to marry him, told him that unless he became
eparch, she would not marry him. When he had obtained this position, she
told him that unless he renounced the religion of the idols and became
a Christian, she would have nothing to do with him. Eleusius then
told Juliana's father of this. He attempted to turn her from the Faith
of Christ, but when he saw that she could not change her constancy,
he gave her up to the Eparch, Eleusius her betrothed, to be tried
according to the law. When he could not persuade her to do his will, he
subjected her to the most inhuman tortures and after imprisoning her, cast
her into a furnace. But by the grace of God, the furnace was
marvellousy quenched. Seeing this, some five hundred men and one hundred and
fifty women believed in Christ and were beheaded for His sake. After
further torments, she was beheaded, in the year 299.

Kontakion in the First Tone
A comely virgin wast thou, O wise Juliana; and as thy soul was
wounded with love for thy Maker thy body was also pierced through with
comely martyric wounds, which adorned thee as the bride of Christ and
His Martyr; now as thou dost dwell in the bridechambers of Heaven,
thou prayest for all of us.
