Demeter is said to be the god of agriculture in charge of grains, vegetables and flowers. She has a beautiful daughter, Persephone. Hades took Persephone and became his queen. Demeter was very sad at the loss of her daughter. He looked for her everywhere, so that the field was deserted and yellow. So Zeus persuaded the guardian to return Persephone to her mother. But because Persephone ate Pluto's food, she had to live with Pluto for six months in a year and return to her mother for the rest of the year. In this way, whenever she was with her mother Demeter, Demeter revived the earth. It's spring and summer. When Persephone returned to the ground, Demeter was eager to cultivate, and the particles on the ground were not harvested and the leaves fell. It's late autumn and severe winter. It is said that this is how the four seasons come. Virgo is Demeter's incarnation. When spring comes, Virgo rises from the eastern horizon, but in winter, Virgo can't see its light.
