I loved myths, fairy tales and legends as a kid. It was all just stories, and I was an avid reader, even at that age. I have my grandmother's copy of "Bullfinch's Mythology" and may have to get it out this evening in reaction. I don't ever recall studying it in school-I just liked it so read the stories on my own (my school was small enough that there were really no gifted classes).
We didn't study it a lot, but my English teacher in 7th grade took us all to the theatre to watch "Clash of the Titans" when it came out (1981). Then we discussed the mythology. I also bought books on the topic because, come on - Greek mythology is AWESOME!
I don't know how people can follow references in movies, etc without knowing at least some Greek mythology. When I was doing a week-long course for OBE, the English presenter asked us, "So who was Prometheus?" I was the only person who knew!!! In a room of 40 teachers!!! And what gets me is how modern writers often present the stories of, say, Sisyphus and Tantalus as terrible tragedies because all they know is their punishments in the underworld. "Oh, the guy with the rock. The guy who tried to eat/drink and the branches bent away..." If they knew the legends they'd know those guys got what was coming to them.
Sorry, I went on a bit there.
Greek (I made a typo the first time and typed "Geek", heh) mythology underpins a lot of our modern culture. I think people need
to know this stuff.
