St Margaret Of Antioch

Her feast day is July 20, St Margaret of Antioch is one of the Fourteen Holy Helpers (auxiliary saints responsible for various aspects of our health) of the Catholic Church, originally venerated in the Eastern Orthodox church as Marina. She gets July 17 in the Eastern church.

She's regarded as a protector-ess against demonic powers generally, but has been frequently associated in particular with being the patron saint of childbirth, where long strips of parchment with her life story written on it were fastened around the waists of women in labour. The story might provide some notion of the reasoning for the action.....

According to the Golden Legend, she was a native of Antioch, daughter of a pagan priest named Aedesius. She was scorned by her father for her Christian faith, and lived in the country with a foster-mother keeping sheep. Olybrius offered her marriage at the price of her renunciation of Christianity. Her refusal led to her being cruelly tortured, and after various miraculous incidents, one of which involved getting swallowed by Satan in the shape of a dragon, from which she escaped alive, when the cross she carried irritated the dragon's innards, she was beheaded in A.D. 304. The Golden Legend, in an atypical moment of scepticism, describes this last incident as "apocryphal and not to be taken seriously".

Go those indulgences, baby.
