Most famous mystery religion of ancient Greece.
It was 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 the 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.
