In Mediterranean myths, the goddess responsible for the changing seasons is Demeter. As the goddess of agriculture and fertility, Demeter's emotional bond with her daughter Persephone directly influences the cycles of nature. Her grief during Persephone's absence in the underworld leads to winter, while her joy upon her return heralds spring. This duality encapsulates themes of life and death, highlighting the seasonal rhythms of growth and decay inherent in the agricultural cycle, thus reinforcing the interconnectedness of familial ties and nature’s patterns.
