The rites of the Eleusinian Mysteries, begun on the Festival days of the 18th and the 19th, would continue with initiations taking place in an underground chamber full of passageways and sacred objects. These rites would continue till the end of the month. Triptolemus, who had been cured of a childhood illness by Ceres, was taken around the world on a chariot and shown the wonders of nature. When he returned home to Eleusis he built a magnificent temple to Ceres and established the worship of the goddess. These rites, the Eleusinian Mysteries, surpassed all other Greek religious celebrations in their solemnity and splendor.
