There is this first benefit from myths, that we have to search and do not have our minds idle. That the myths are divine can be seen from those who have used them. Myths have been used by inspired poets, by the best of philosophers, by those who established the mysteries, and by the Gods themselves in oracles. But why the myths are divine it is the duty of philosophy to inquire. Since all existing things rejoice in that which is like them and reject that which is unlike, the stories about the Gods ought to be like the Gods, so that they may both be worthy of the divine essence and make the Gods well disposed to those who speak of them: which could only be done by means of myths.
4th-century Roman philosopher and writer
Sallustius or Sallust (Σαλούστιος) was a 4th-century Latin writer, a friend of the Roman Emperor Julian. He wrote the treatise On the Gods and the Cosmos, which owes much to the work of Iamblichus of Chalcis, who synthesized Platonism with Pythagoreanism and theurgy, as well as to Julian's own philosophical writings. Though uncertainty remains, and some have identified him with the praetorian prefect of Gaul, Flavius Sallustius, he is widely thought to have been Saturninius Secundus Salutius, praetorian prefect of the Orient in 361, who declined the army's offer to become Emperor after the death of Julian, after which Jovian accepted the position.

The essences of the Gods never came into existence (for that which always is never comes into existence; and that exists for ever which possesses primary force and by nature suffers nothing): neither do they consist of bodies; for even in bodies the powers are incorporeal. Neither are they contained by space; for that is a property of bodies. Neither are they separate from the first cause nor from one another, just as thoughts are not separate from mind nor acts of knowledge from the soul.
Those who wish to hear about the Gods should have been well guided from childhood, and not habituated to foolish beliefs. They should also be in disposition good and sensible, that they may properly attend to the teaching. They ought also to know the common conceptions. Common conceptions are those to which all men agree as soon as they are asked; for instance, that all god [here and elsewhere, = godhood, divine nature] is good, free from passion, free from change. For whatever suffers change does so for the worse or the better; if for the worse, it is made bad; if for the better, it must have been bad at first.
