St Matrona of Thessalonica (4th c.)
She was a servant of the Jewish wife of the governor of Thessalonica. When she refused to enter the synagogue with her mistress, she was beaten, then locked in a cell until she starved to death. Finally, her mistress ordered her body thrown from the roof of the house and left to lie in the open. Christians took her body and buried it honorably, and the bishop, Alexander, built a church over her grave.
