Saint Crispina (died December 5, 304) was a martyr of Africa who suffered during the Diocletian persecution. She was born at Thagara (Thacora, Tagora) (now an archaeological site in Tunisia near the town Taoura) in the Roman province of Africa. She died by beheading at Theveste, in Numidia.
Crispina belonged to a distinguished family and was a wealthy matron with children. At the time of the persecution she was brought before the proconsul Annius Anullinus; on being ordered to sacrifice to the gods she declared she honoured only one God.
Her head was shaved at the command of the judge, and she was exposed to public mockery, but she remained steadfast in the Faith and was not moved even by the tears of her children. When condemned to death, she thanked God and offered her head with joy for execution.
The Acts of her martyrdom, written not long after the event, form a valuable historical document of the period of the persecution. The day of St. Crispina's death was observed in the time of Augustine of Hippo; in his sermons Augustine repeatedly mentions her name, as well known in Africa and worthy to be held in the same veneration as the names of Saint Agnes and St. Thecla.
Thierry Ruinart in his collection of the Acts of the martyrs gives the account of her examination.
