95 Lucifer the bishop PL 23, 697
Lucifer, bishop of Cagliari, was sent by Liberius the bishop, with Pancratius and Hilary, clergy of the Roman church, to the emperor Constantius, as legates for the faith. When he would not condemn the Nicene faith as represented by Athanasius, sent again to Palestine, with wonderful constancy and willingness to meet martyrdom, he wrote a book against the emperor Constantius and sent it to be read by him, and not long after he returned to Cagliari in the reign of the emperor Julian and died in the reign of Valentinian.
Lucifer, Caralitanus episcopus, cum Pancratio et Hilario Romanae Ecclesiae clericis, ad Constantium imperatorem a Liberio episcopo, pro fide legatus missus, cum nollet sub nomine Athanasii Nicaenam damnare fidem, in Palaestinam relegatus, mirae constantiae et praeparati animi ad martyrium, contra Constantium imperatorem scripsit librum, eique legendum misit, ac non multo post, sub Juliano principe, reversus Caralis, Valentiniano regnante, obiit.
Λουκίφερ, Καρακάλεως ἐπίσκοπος, ἅμα Παγκρατίῳ καὶ Ἱλαρίῳ τῆς Ἐκκλησίας Ῥώμης Κληρικοῖς, πρὸς Κωνστάντιον βασιλέα παρὰ Λιβερίου ἐπισκόπου, ὑπὲρ τῆς πίστεως εἰς πρεσβείαν σταλεὶς, μὴ βουλόμενος ἐπ' ὀνόματι Ἀθανασίου τὴν Νικηνὴν συνόδον καταλῦσαι, εἰς Παλαιστίνην ἐξορισθεὶς, θαυμαστῆς ἐγκρατείας καὶ εὐπρεπισμένου λογισμοῦ εἰς μαρτύριον, συνέταξε λόγον κατὰ Κωνσταντίου, τοῦτόν τε αὐτῷ ἀπέστειλεν ἀναγνωσθησόμενον, καὶ μετ' οὐ πολὺ βασιλεύοντος Ἰουλιανοῦ, εἰς τὴν Καρακαλίνων ἀναζεύξας, ἐπί Βαλεντινιανοῦ βασιλέως ἐτελεύτησεν.
