martyrdom · 310 · Caesarea Maritima
He was beheaded on 16 February 310 with eleven others, at the end of two years in prison. Eusebius wrote a Life of Pamphilus in three books; it is lost, and the loss is one of the sharper ones, because the man who wrote it had been in the same cell. What survives is the Martyrs of Palestine, where the deaths of that persecution are recorded by someone who watched them, and the signature. For the rest of his life Eusebius called himself Eusebius Pamphili — Eusebius, Pamphilus' man — which is how a pupil says something a title cannot.
To finish, in the last years of the Great Persecution, with the presbyter who had made Caesarea a centre of learning.
A book about him by his own pupil, now lost, and a name that pupil carried for the rest of his life.
