The real Apollo would have impregnated Palamis in a heartbeat, willing or not...
According to
The Star Trek Compendium, an early draft of the script ended with Carolyn Palamas pregnant with Apollo’s child.
Heh, no wonder it was an early draft then.
I just watched this episode again. It's... amazing how time will change your perspective on things. When I was younger, I didn't care much for this episode for the lack of ship action. And now, I can really appreciate what it has to offer. It's a great story. And the acting is excellent. There are some wonderful moments between Kirk, Scotty, McCoy, and Chekov.
The only things I might say against it is that the being Apollo was just way too single-minded on subjugating the landing party. There was no discussion or compelling offerings. He didn't really push the upside of what he'd be offering them, leaving the core of it to appear as slavery. But perhaps this was to show the difference between the classical Greek God and humanity 5,000 years later. Also, Apollo fused the phasers to no longer function and said "none of your other toys will function either", yet the tricorders continued to function and later on they could use their communicators. A bit of an obvious slip-up. In any case... an episode well done.
Overall, I think that
was Apollo. The idea proffered was that back in the Greek days, we'd been visited by extraterrestrial beings that, having super powers like what we saw, masqueraded as "Gods". They enjoyed the game, the manipulation, and entrenched themselves in Greek society. But perhaps there was a gradual decay of morality that caused them to lose their advantage... without belief from the worshipers, they didn't have that kind of power any longer, to move mankind with mere suggestion. And so, they eventually had to leave. I can see it as if it were real. Kind of a compelling idea, well played out in this episode.
