What is Demeter claim to fame?

Answer 1

She's famous because Hades, the God of the Underworld, was shot by Cupid and fell instantly in love with her daughter, the Goddess of Spring, also known as Persephone. He opened up a black pit beneath her and she fell into the Underworld. She was forced to marry him. Demeter, frantic about the loss of her daughter, makes sure none of the crops grow in her misery. As mankind is starving, Zeus finally sends Hermes to find out what happened. Hermes talks to a farmer who lost his pigs mysteriously in what he described as a "pit as black as the night sky". He also interrogates the God of the Sun, who found out what happened. Zeus orders Hades to give Persephone back, but only if she didn't eat any food while in the Underworld. Persephone, unfortunately, had consumed three pomegranate seeds, and was forced to stay in the Underworld for half the year and could stay with her mother for the other half (Her mother is Demeter, remember.) So while Demeter had her daughter, the Earth enjoyed Spring and Summer. But when Persephone was forced to join Hades the other half of the year, Demeter made the land suffer during her misery, producing Fall and Winter. That's how the seasons were born, and that's how Demeter got famous.
