The Greek goddess known for her association with the harvest and agriculture is Demeter. She is revered as the goddess of fertility, grain, and the earth, playing a crucial role in the agricultural cycle. Demeter’s relationship with her daughter Persephone, who was abducted by Hades, symbolizes the changing seasons. When Persephone is in the underworld, Demeter mourns, leading to winter; when she returns, it brings spring and renewal. This myth emphasizes the interconnectedness of life, death, and rebirth in nature.
