Most famous Mystery Religion of ancient Greece. It is based on the story of Demeter, whose daughter Persephone was kidnapped by Hades. While searching for her daughter, Demeter stopped at Eleusis, revealed her identity to the royal family, and taught the natives her rites. The Greater Mysteries were celebrated in autumn, beginning with a procession from Athens to temple at Eleusis. This was followed by a ritual bath in the sea, three days of fasting, and completion of secret rites. Initiates were promised personal salvation and benefits in the afterlife.
