Of Agapius we know only what Eusebius tells us in this passage. He was the immediate predecessor of Eusebius in the church of Cæsarea, and probably survived the persecution, but not for many years (see above, p. 10 sq.). Eusebius speaks of him in the past tense, so that he was clearly already dead at the time this part of the History was written (i.e. probably in 313; see above, p. 45).
