Why does everyone make such a big deal out of the story of Hades and Persephone?

kata-chthonia:

“Prior to the coming of Rome, the only road in ancient Greece which was not a goat path was the Sacred Way which led from Athens to the city of Eleusis, site of the Rites of Demeter.”

PROBABLY BECAUSE THEY WERE A BIG DEAL TO THE ANCIENT GREEKS??
