Martyrs Menodora, Metrodora, and Nymphodora

Menodora, Metrodora, and Nymphodora were three virgin sisters of Bithynia in the early fourth century, who from their youth had withdrawn from the world together and lived a solitary life in the foothills above a mineral spring known for its healing waters. They came to the notice of the surrounding population because pilgrims to the spring would often turn first to the cell of the three sisters for prayer, and many healings were attributed to their intercession.

During the persecution of Maximian Galerius, the magistrate Frontonus arrested them on a denunciation. He attempted by separate examinations to play one sister against the others, hoping that the death of the elder would persuade the younger to recant. Menodora was tortured to death before her sisters' eyes; when Metrodora was told that she could save herself by sacrifice, she replied that she wished only to follow her sister to the Kingdom and was tortured to death in turn; Nymphodora, the youngest, was crowned the same way.

Their bodies were thrown into a fire, and their relics were gathered afterward by Christians of the place. Their joint feast is kept on September 10.
