In Greek mythology, Persephone plays a critical role in the changing seasons through her cycle between the Underworld and the surface world. As the daughter of Demeter, the goddess of agriculture, Persephone’s annual descent into the Underworld causes Demeter to grieve, leading to winter. In contrast, her return signifies spring and the renewal of life. Thus, Persephone embodies the cycle of life and death, illustrating how her presence directly influences the fertility of the earth and agricultural abundance.
