*Do Pagans eat meat?*
I don’t. As Porphyry, blessed by the Gods, argued, the consumption and sacrifice of meat is immoral. The mystery of Elusis maintained three laws for worshippers: honor your parents/ancestors, offer to the gods from the fruits of the earth, and harm no animals.
These three laws come from Porphyry who quotes Athenian law makers. His claim was that the ancient laws of Athens were only preserved in Elusis and had been abandoned in other places.
*Should we apply or consider the roman mythos when talking about Greek mythology?*
Yes - the Gods inspire the mythological works of the poets and that didn’t stop because the poets spoke a different language (this applies to any modern language too, as the gods are obviously immortal and still present in our world today).
The gods are immortal beings who are present for all people and transcend changing cultural stereotypes.
