Saint Anysia of Thessalonica (Greek: Άγία Άνυσία) was a Christian virgin and martyr of the 4th century. Anysia was born to a wealthy and pious Christian family in Thessalonica. She dedicated herself to vows of chastity and poverty, praying and helping the poor.
The legend of her martyrdom states that, in 304, a Roman soldier apprehended her as she was on her way to Mass. Discovering she was a Christian, he beat her, and intended to drag her to a pagan temple to sacrifice to Roman gods. When he tore off her veil (a reminder of her vow of chastity), she spat in his face, and he murdered her.[2]
