The Greek goddess associated with agriculture and fertility is Demeter. Revered as the goddess of the harvest, Demeter is central to farming, the seasons, and the nourishment of the earth. Her myth relates closely to the cycle of life and death, particularly through her daughter Persephone, who resides in the underworld for part of the year. This seasonal cycle reflects agricultural practices and underlines the connection between human existence and the natural world, where Demeter's grief directly impacts the fertility of the land.
