Virgin Martyr Helen of Sinope, a young Christian who suffered for her faith under Ottoman rule.
Saint Helen was a young woman of Sinope on the Black Sea coast of Asia Minor. Tradition relates that a local Ottoman official, struck by her beauty, tried to force her to renounce Christ and marry him; she refused steadfastly.
She was imprisoned and tortured, and finally put to death for her faith. Her relics were honoured by the Greek Christians of Sinope and later carried to Greece by refugees, where her veneration continues.

On the New Calendar, Helen of Sinope is commemorated on November 1. Churches on the Old (Julian) Calendar keep the feast on November 14 of the civil calendar.
