Baring-Gould’s sources: By the Greeks on April 3rd, and May 29th; on April 3rd, in the ancient Martyrology attributed to S. Jerome. On the 2nd, by the Roman Martyrology, and by that of Ado. Authority: — Eusebius, in his Hist, of the Martyrs of Palestine, c. 7.] Eusebius thus describes the martyrdom of Theodosia, of which he was eye-witness. “The persecution had now extended to the fifth year, when on the fourth of the nones of April, on the very day of our Lord's Resurrection, a virgin of Tyre, named Theodosia, not yet aged eighteen, distinguished by her faith and virtue, in Caesarea, approached some prisoners, confessors of Christ, seated before the judgment-seat, with the purpose of apparently saluting them, and entreating them to remember her when they appeared before the Lord. Whilst she was so doing, she was seized by the soldiers, and led before the commander. Presently, merciless and savage as he was, he had her tortured with dreadful cruelties, furrowing her sides and breasts with instruments, to the very bones, and then ordered her, yet breathing, and withal cheerful of countenance, to be cast into the sea.”

Her relics [the bodily remains of a saint, or objects they used, kept with honor] were removed to Constantinople, where May April *.] ^S*. Mary & Zosimus. 29th was observed as the feast of the translation. The body was said to have been enshrined by Roger, Abbot of Dervum, in the monastery Church of Moutier en Der, on the Voire. But a portion of the body is also said to have been brought from the East and presented to the Cathedral of Ltege, in the time of Notker. However the entire body of S. Theodosia is shown at Bologna by the Trinitarians; and another entire body, also asserted to be that of the Virgin Martyr of Caesarea is preserved at Salvatierra, near Vittoria in the north of Spain.
