The soul descends Corically [or after the manner of Proserpine] into generation, but is distributed into generation Dionysiacally, and she is bound in body Prometheiacally and Titanically: she frees herself therefore from its bonds by exercising the strength of Hercules; but she is collected into one through the assistance of Apollo and the savior Minerva, by philosophical discipline of mind and heart purifying the nature. – Olympiodorus
Orphic Mysteries
What Orpheus delivered in hidden allegories, Pythagoras learned when he was initiated into the Orphic Mysteries; and Plato next received a perfect knowledge of them from the Orphean and Pythagorean writings. – Proclus

The State of the Soul After Death
Lastly, that I may comprehend the opinion of the ancient theologists, on the state of the soul after death, in a few words: they considered, as we have elsewhere asserted, things divine as the only realities, and that all others were only the images and shadows of truth. Hence they asserted that prudent men, who earnestly employed themselves in divine concerns, were above all others in a vigilant state. But that imprudent [i. e. without foresight] men, who pursued objects of a different nature, being laid asleep, as it were, were only engaged in the delusions of dreams; and that if they happened to die in this sleep, before they were roused, they would be afflicted with similar and still more dazzling visions in a future state. And that as he who in this life pursued realities, would, after death, enjoy the highest truth, so he who pursued deceptions would hereafter be tormented with fallacies and delusions in the extreme: as the one would be delighted with true objects of enjoyment, so the other would be tormented with delusive semblances of reality. Ficinus
