The chthonic goddess Persephone plays a crucial role in Greek agriculture myths, symbolizing the cycle of death and rebirth. As the queen of the underworld, her seasonal descent and return to the earth signify the changing of seasons and the growth of crops. When Persephone is in the underworld, her absence leads to winter, while her return heralds spring and agricultural abundance. This duality reflects the interconnectedness of life and death, illustrating the importance of her myth in explaining natural cycles and the relationship between humans and the land.
