The existence of Christina herself is poorly attested. Some versions of her legend place her in Tyre (Phoenicia), other evidence points to Bolsena, an ancient town in central Italy, near an Etruscan site called Volsinium, with catacombs in which archeologists have found the remains of an early Christian church and the tomb of a female martyr. Inscriptions found on the site confirm that this martyr had a name like Christina and that the local community was venerating her as a saint by the end of the fourth century.
