The term 'Harvest Goddess' refers to three deities from Greek mythology: Ops, CERES, and DEMETER. Ops was the goddess of fertility and abundance, while CERES was the goddess of agriculture and grain. DEMETER was the goddess of the harvest, and was the most widely worshipped of the three. All three goddesses were associated with the cycle of life, death, and rebirth, and were seen as symbols of abundance and prosperity.
