Most of us just get taught the Greek/Roman set, and parts of the Abrahamic set. And not many 'dryer-setting' people read world mythology for fun.

I did read a story once that used Egyptian mythology as an example of time travel where contradictory stuff could be simultaneously true. (I.e. being someone's parent /and/ child.) I can't say for sure how accurate the mythology or history was. The 'be nice to the reanimated dead guy who just read his own memorial' bit seemed to be really well done.
