There is no Saint Apollonian. However, there is a Saint Apollonia of Alexandria. She was a consecrated virgin and deaconess. During an anti-Christian uprising in Alexandria, Egypt, that was caused by a pagan prophecy, the mob seized Apollonia as a leader among the local Christians. After her teeth were broken with pincers, she was given the choice of renouncing Christ or being burned alive; she leaped onto the fire herself, about the year 249. She would have been proclaimed a saint by popular acclamation and the approval of a bishop. There was no official canonization process at the time she was martyred.
