I wanted to add my two cents on the "self-generated" images. As soon as I heard that, I immediately thought of the idealist view of the gods. And I agree with Cassius that these "images" would spontaneously occur from particles at random. And these would arguably be so fine that they would only be perceived by the mind not the physical senses. I don't agree that he's talking about pictures we see in clouds. (*See addendum below)
I also think that Epicurus via Lucretius is adamant about receiving particles *from* bodies to contrast with other philosophers that said vision was possible by something coming from the viewer (like a flashlight).
Addendum: Finished the full episode: Now I'm not so sure about the self-begotten. On second hearing and doing some reading, it seems he might be talking about the images we see in clouds and how we may *see* giants et al but there aren't giants shedding their images for us to see. We are perceiving giants where none exist. This whole thing is more subtle than my perfunctory post let on. But I think it may still have wider implications. I'm going to delve into the Latin a little although I am woefully ill-equipped to say anything about that. Full disclosure there ![]()
Addendum 2: Checked Stallings, and, yeah, she does a good job of clearing up the ambiguity in the other translations. It's the faces in clouds. But in Loeb, it also references the section on centaurs and other mythological creatures. So there's more going on with the eidola/simulacra/images/idols here. Looks like an interesting ride coming up in DRN!
