Church History by Eusebius Pamphilius
Chapter XXVII.--The Works of Others that flourished at that Time.
Numerous memorials of the faithful zeal of the ancient ecclesiastical men of that time are still preserved by many. Of these we would note particularly the writings of Heraclitus On the Apostle, and those of Maximus on the question so much discussed among heretics, the Origin of Evil, and on the Creation of Matter. Also those of Candidus on the Hexæmeron, and of Apion on the same subject; likewise of Sextus on the Resurrection, and another treatise of Arabianus, and writings of a multitude of others, in regard to whom, because we have no data, it is impossible to state in our work when they lived, or to give any account of their history. And works of many others have come down to us whose names we are unable to give, orthodox and ecclesiastical, as their interpretations of the Divine Scriptures show, but unknown to us, because their names are not stated in their writings.
