The goddess representing the harvest and fertility in ancient Greek culture is Demeter. She is associated with the growth of crops and the changing of the seasons. Demeter is often depicted with symbols like wheat and the cornucopia, embodying the Earth's abundance. Her most notable myth involves her daughter Persephone, whose abduction by Hades led to the cycle of the seasons, indicating a connection between life, death, and rebirth. Demeter's significance is highlighted in the Eleusinian Mysteries, which celebrated agricultural cycles and the afterlife.
