There's an episode where they find a huge underwater pyramid that has ancient Greek writing on it. A character gets possessed and starts speaking Greek. It turns out it's The Temple of Minerva built by Neptune. Now if you had a thing for mythology, like I did, as a kid you probably notice those are the Roman names of the gods. And Minerva is a black woman. This is in the early 90s.
This "replacement rot" has been going on for a long time
Was that the episode where Neptune actually shows up and one guy says he doesn't want the story to come out because he wants to run for office?
That be the one
That's one of the few episodes I've seen. It turned me off from the whole show.
Yeah the pointing out it's an ancient Greek temple, using Greek language, and showing Greek writing but using Roman names was silly.
Honestly, that's common even among college professors. The guys who study it directly screw it up, and then lecture us on the differences. Hercules is very different even on the era let alone Greek and Roman.
