1. The first of these was Plutarch, who was mentioned just above. As he was led to death, the man of whom we are speaking being with him at the end of his life, came near being slain by his fellow-citizens, as if he were the cause of his death. But the providence of God preserved him at this time also.
2. After Plutarch, the second martyr among the pupils of Origen was Serenus, who gave through fire a proof of the faith which he had received.
3. The third martyr from the same school was Heraclides, and after him the fourth was Hero. The former of these was as yet a catechumen, and the latter had but recently been baptized. Both of them were beheaded. After them, the fifth from the same school proclaimed as an athlete of piety was another Serenus, who, it is reported, was beheaded, after a long endurance of tortures. And of women, Herais died while yet a catechumen, receiving baptism by fire, as Origen himself somewhere says.
