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

As Narcissus, by catching at the shadow, plunged himself in the stream and disappeared, so he who is captivated by beautiful bodies, and does not depart from their embrace, is precipitated, not with his body, but with his soul, into a darkness profound and repugnant to intellect (the higher soul), through which, remaining blind both here and in Hades, he associates with shadows. Plotinus
