Nicene and Post-Nicene Fathers, Ser. II, Vol. III:
Jerome and Gennadius. Lives of Illustrious Men.: Heliodorus the presbyter.

Chapter VI.

Heliodorus 2580 the Presbyter wrote a book entitled An introductory treatise on the nature of things, in which he showed that the beginning of things was one, that nothing was coaeval with God, that God was not the creator of evil, but in such wise the creator of all good, that matter, which is used for 2581 evil, was created by God after evil was discovered, and that nothing material whatever can be regarded as established in any other way than by God, and that there was no other creator than God, who, when by His foreknowledge He knew that nature was to be changed, 2582 warned of punishment.
