In Greek mythology, Hypnos, the god of sleep, created a poppy drink to quell the grief of the corn goddess Demeter whose daughter, Persephone, had been abducted to the underworld. While Demeter mourned, famine covered the land. Hypnos’s drink forced Demeter into a state of gentle slumber and healing. She awakened comforted, and the world was made green again. To this day some farmers sow poppies among the corn plants to ensure a healthy harvest.
