When I read the reference of St Athanasius to the martyrs, I remembered the liturgies that dates the age of St Athanasius:
Roman Canon:
In union with the whole Church we honor Mary, the ever-virgin mother of Jesus Christ our Lord and God. We honor ... the apostles and martyrs Peter and Paul, Andrew, James, John, Thomas, James, Philip, Bartholomew, Matthew, Simon and Jude; we honor Linus, Cletus, Clement, Sixtus, Cornelius, Cyprian, Lawrence, Chrysogonus, John and Paul, Cosmas and Damian and all the saints. May their merits and prayers gain us your constant help and protection, through Christ our Lord. Amen.
Anaphora of Addai and Mari:
Pray for the memorial of our fathers, the catholicoi and bishops, and all presbyters, deacons, young men, and virgins; all those who have departed and gone from this world in the true faith; all our fathers and brothers; all our sons and daughters; all faithful, Christ-loving kings; all prophets and apostles; and all martyrs and confessors, here and everywhere, that God may crown them at the resurrection from the dead, and give us a good hope and portion with them, and an inheritance and life in the kingdom of heaven. - And may this oblation be accepted with confidence.
And I remember you that still now the OO Coptic Church (the Church of St Athanasius) starts his calendar not since the birth of Christ, but since the 284, when the Emperator Diocletian got the power, in remembrance of the huge persecutions under him: it is called "age of Martyrs".
And St Athasius (296-373) is near in time to this huge persecution
