"But those," says Proclus, "who treat of divine concerns in an indicative
manner, either speak symbolically and fabulously, or through images. And of
those who openly announce their conceptions, some frame their discourses
according to science, but others according to inspiration from the gods.
And he who desires to signify divine concerns through symbols is Orphic,
and, in short, accords with those who write fables respecting the gods.
But he who does this through images is Pythagoric. For the mathematical
disciplines were invented by the Pythagorean in order to a reminiscence of
divine concerns, to which through these as images, they endeavour to
ascend. For they refer both numbers and figures to the gods, according to
the testimony of their historians. But the enthusiastic character, or he
who is divinely inspired, unfolding the truth itself concerning the gods
essentially, perspicuously ranks among the highest initiators. For these do
not think proper to unfold the divine orders, or their idioms, to their
familiars through veils, but announce their powers and their numbers in
consequence of being moved by the gods themselves. But the tradition of
divine concerns according to science is the illustrious, prerogative of the
Platonic philosophy. For Plato alone, as it appears to me of all those who
are known to us, has attempted methodically to divide and reduce into order
the regular progression of the divine genera, their mutual difference, the
common idioms of the total orders, and the distributed idioms in each."

Again, since Plato employs fables, let us in the first place consider
whence the ancients were induced to devise fables, and in the second place,
what the difference is between the fables of philosophers and those of
poets. In answer to the first question then, it is necessary to know that
the ancients employed fables looking to two things, viz. nature, and our
soul. They employed them by looking to nature, and the fabrication of
things, as follows. Things unapparent are believed from things apparent,
