On the episcopacy of Demetrius, see Bk. V. chap. 22, note 4. Forty-three years, beginning with 189 a.d., bring us down to 232 as the date of his death, and this agrees excellently with the statements of this chapter. ↩

Firmilian, bishop of Caesarea, the capital of Cappadocia (to be distinguished from Caesarea in Palestine), was one of the most famous prelates of his day in the Eastern Church. He was a friend of Origen, as we learn from the next chapter, and took part in a council called on account of the schism of Novatian (see chap. 46), and also in councils called to consider the case of Paul of Samosata (see Bk. VII. chaps. 28 and 30). He was one of the bishops whom Stephen excommunicated because they rebaptized heretics (see Bk. VII. chap. 2, note 3, and chap. 5, note 4), and he wrote an epistle upon this subject to Cyprian, which is extant in a Latin translation made by Cyprian himself (Ep. 74, al. 75, in the collection of Cyprian's epistles. See Dict. of Christ. Biog. I. 751, note). Basil (de Spiritu Sancto, 29) refers to works (logoi) left by Firmilian, but none of them are extant except the single epistle mentioned, nor do we hear from any other source that he was a writer. Jerome does not mention him in his De vir. ill. The exact date of his accession is unknown to us, as it very likely was to Eusebius also. He was a bishop already in the tenth year of Alexander (231 a.d.), or very soon afterward, and from Bk. VII. chap. 30, we learn that he died at Tarsus on his way to Antioch to attend a council which had been summoned to deal with Paul of Samosata. This synod was held about 265 a.d. (not in 272 as is commonly supposed; see Bk. VII. chap. 29, note 1), and it is at this time, therefore, that we must put the death of Firmilian; so that he was bishop of Caesarea at least some thirty-four years. ↩
