The Holy Martyr Tryphaina came from the city of Cyzicus. She tried to convert the pagans to Christ, and was arrested for this. When threats and flattery had no effect on her, she was tortured. They threw her into a red-hot oven, tied her from a high tree, threw her onto sharp spears. Then they took her away to be devoured by beasts, but the Lord preserved her unharmed. Finally, she was killed by a mad bull.

Women who have difficulty nursing their babies pray to St Tryphaina.
