The Greek goddess often depicted with a harvest sheaf and accompanied by a snake is Demeter. As the goddess of the harvest, she represents agriculture, fertility, and the changing seasons. The sheaf symbolizes nourishment and the fruits of the earth, while the snake may denote renewal and transformation. Demeter's most famous myth involves her daughter, Persephone, whose annual descent to the underworld represents the cycle of life and death. Through her myths, Demeter epitomizes the vital connection between humanity and nature, brought to life in rituals celebrating the harvest and the importance of sustenance.
