They threw Tatiana into a fire, but the fire did not harm the martyr. The pagans, thinking that she was a sorceress, cut her hair to take away her magical powers, then locked her up in the temple of Zeus.
On the third day, pagan priests came to the temple intending to offer sacrifice to Zeus. They beheld the idol on the floor, shattered to pieces, and the holy martyr Tatiana joyously praising the Lord Jesus Christ. The judge then condemned the valiant sufferer to be beheaded with a sword. Her father was also executed with her.
Tatiana is venerated as a saint, and her feast day is on January 12 (for those churches which follow the traditional Julian Calendar, January 12 currently falls on January 25 of the modern Gregorian Calendar). The miracles performed by Saint Tatiana are said to have converted many people to the fledgling religion. Saint Tatiana is patron saint of students. In Belarus, Russia, and Ukraine, Tatiana Day, also known as "Students Day", is a public holiday.
