Triptolemos and Demeter at Eleusis
Beginning at least as early as the Late Bronze Age (about 1400 BC) and maybe much earlier even than that, the people of Eleusis in Greece celebrated a holiday there every year that celebrated the time when the goddess Demeter gave wheat and barley to the people to eat.
According to the Greek story, when Demeter was searching all over the world for her kidnapped daughter Persephone, she came to a house where she asked to stay the night as a guest. Her host, Celeus, was very welcoming. He was so friendly that Demeter wanted to give him a reward. Demeter thought she would reward Celeus by making his son Demophon immortal, so she began burning away his mortality in the fire every night. But one night Demophon's mother Metanira came in and was horrified to see her baby burning in the fire. Metanira snatched her baby away from Demeter, and that was the end of that.
So Demeter thought she would reward Demophon's twin brother Triptolemus instead. She taught Triptolemus how to grow wheat and barley, and lent him a winged chariot so he could fly all over Greece and teach people everywhere how to grow grain. (Compare this to the African story of Anansi teaching people to farm, or the Mayan story of Maize Mountain.)
The celebration itself was part of a mystery cult known as the Eleusinian Mysteries. It began in the evening, with crowds of people, all dressed in plain white tunics, having a torchlight parade down to the beach and wading out into the water with their torches. That must have been very beautiful to see!
After the bathing, the crowd of people walked back to town and went inside the big temple of Demeter at Eleusis. There the priest showed them the sacred objects - but we don't know exactly what the sacred objects were, because this was a secret known only to people who had actually been there. Probably the priest showed them a sheaf of wheat, but maybe there were other things too.
