In ancient Greek religion and mythology, Demeter is the Olympian goddess of the harvest and agriculture, presiding over crops, grains, food, and the fertility of the earth. Although Demeter is mostly known as a grain goddess, she also appeared as a goddess of health, birth, and marriage, and had connections to the Underworld. She is also called Deo. In Greek tradition, Demeter is the second child of the Titans Rhea and Cronus, and sister to Hestia, Hera, Hades, Poseidon, and Zeus. Like her other siblings except Zeus, she was swallowed by her father as an infant and rescued by Zeus.
