For 10 points, name this goddess of the seasons and the harvest, the mother of Persephone.
In one myth, Zeus struck this figure's lover Iasion in the face with a thunderbolt after he saw mud on her back from their tryst in a field. Though she hid among the mares of Onkios, Poseidon was still able to find her and impregnate her, resulting in the birth of Despoine. In another myth, this deity disguised herself as the nurse Doso and attempted to burn away Demophon's immortality, but after Metanira stopped her, she taught her skills to Triptolemus. However, this deity is perhaps most famous for ending the harvest after her brother, Hades, took her daughter while she was picking flowers in a field.
