It may simply be that Celestia doesn't have time to check on everypony's education all the time. Smaller towns like ponyville might slip into myth while a larger city like Canterlot would have more accurate records. Or maybe Celestia doesn't have much at all to do with the education system, and lets it do as it would. Although that misses out on the wonderful opportunity of Celestia giving a guest lecture on Equestrian history and Canterlot university
I wouldn't expect her to allow that sort of thing to happen... though I did hear (from Ask Aquilinus, actually) the idea that Celestia sealed herself away in the Everfree Palace for about forty or fifty years after the Nightmare Eclipse, and just refused to come out. That might have been sufficient time for ponies to fall into a mini-dark age and lose some history, and if she tried to reeducate her subjects about Luna once she got back on the throne, it would by necessity end with 'so she went evil, tried to murder you all, and then I sent her away, possibly forever'. Especially when Nightmare Moon is apparently a hated and feared figure, linking your sister to her probably isn't the best way to give her a smooth re-introduction into society. Being forgotten is easier than being demonized for a thousand years, especially when you can then work to make things better.

Yeah, Ponychan is a BAD place to discuss ponies. /pony/ sucks hardcore, but /chat/ and /phoenix/ are nice. and if you like randomness, /oat/ is fun too. As is /pic/. Just stay away from /pony/ and you're in the clear.
Weird thought: Do judge ponies need to use gavels? Or do their hooves suffice?

Didn't Celestia say that she and Luna came to Equestria to free it from Discord? If so I'd imagine that the events of the play take place before any of that. Discord showed up sometime after the founding, and the princesses some time after that. That's what I'm going with for now, though the episode might mess that up completely. I doubt Discord will actually be in the play, just because that seems like a lot of details to cram into a single episode.
Yup, I'm fully willing to get my ideas on the origins of Equestria jossed to shit after this episode. Good thing I've never written them down anywhere!
The gavel gives it an air of authority. Banging your hoof (equivalently a fist) on the table looks like someone getting mad enough to start throwing a temper tantrum.
