Who is the greek goddess who lives under hell?

Answer 1

Persephone, the unwilling bride of Hades. (I'm assuming that's who you are asking about). She is the daughter of the Nature Goddess Demeter. One of my favorite Greek stories is the one on Persephone!

Persephone was out in a field picking flowers in a field

(Note, quick fact, a maiden picking flowers in a field is a sure sign of trouble in Greek Mythology).

Hades saw her and her beauty, and reached up to grab her. He succeeded, and took her down to the underworld as his bride. Demeter searched the world for her lost daughter, and, in her grief, forgot to give Mankind the power of nature. all the crops died, and the human race was dieing.

The other gods ordered Hades to give up Persephone, but Hades had other ideas. He offered Persephone a pomegranate, (a fruit), and she ate six seeds of it. This "gift" was actually a trick. Once you have eaten food of the underworld, you are not allowed to leave. But, (because Persephone was a goddess) and (because Demeter would have continued grieving) the gods made a deal.

Persephone must remain with hades for six months of the year, one month for each seed she ate. This is supposedly the reason why we have summer and winter, because, when Persephone is with her mother, there is happiness and joy and warmth, and crops grow, giving us summer.

But when Persephone returns to the underworld, to hades, Demeter weeps and grieves again, and all turns cold and sad, thus giving us fall and winter.
