She was kidnapped by Zeus's brother, Hades, who'd fallen deeply in love with her one day when he saw her picking wild flowers. Because Persephone ate 4 pomagranant seeds, she couldn't return to her mother. Demeter threatened that the Earth would never bloom and grow again, so Zeus said that 4 out of the 12 months of the year, Persephone would stay with Hades and the other 8 months, she'd stay with Demeter. So, when Persephone is underground, the Earth becomes bare and cold, making winter. It is said that after a while, Persephone became cold and distant like the dead and her husbend, it is also said that she soon began to love him.
Psyche is said to be the goddess of butterflies.
When she became a goddess, the first butterfly became known. Eros went to do his mother's bidding, but when he found Psyche, asleep in her garden, he thought she was the most beautiful mortal he'd ever seen and crept closer. Immediately, he fell deeply in love with her. Psyche, happy for a bit, began to tire of her lonely days and her mysterious husbend. She became unhappy and finally her husbend allowed her sisters to visit.
