On the seventh of September this year (13 Boedromion), the festival of the Greater Eleusinian Mysteries started. The Eleusinian Mysteries (Ἐλευσίνια Μυστήρια) had festivals throughout the year, which were tied to agriculture through Demeter's refusal to perform her duties as an agricultural Theia while her daughter Persephone is with Hades, and to the afterlife and Underworld through Persephone's return to the surface of the earth after Her mandatory stay with Hades has ended. Initiation ceremonies were held every year at Eleusis. Of all the mysteries celebrated in ancient times, the mysteries at Eleusis are assumed to be of great importance to a large portion of the ancient Hellens. The cult itself likely has origins dating back to the Mycenean period of around 1600 to 1100 BC, and it is believed that the cult of Demeter Herself was established in 1500 BC.

The Eleusinian mysteries consist mostly of two festivals, but the worship of Demeter and Persephone consist of a cycle of seven festivals: the Greater Mysteries (13-23 Boedromion), Proerosia (6 Pyanepsion), Stenia (9 Pyanepsion), Thesmophoria (11-13 Pyanepsion), Haloa (26 Poseideon), the Lesser Mysteries (20-26 Anthesterion),  and the Skiraphoria (12 Skirophorion). These are placed in sequence of the Athenian year. Sunset yesterday (or today, depending on the source) marked a special event during the Greater Mysteries, however: the Epidauria.

The Epidauria was a festival of Asklēpiós placed smack in the middle of the Mysteries--exactly six months after the other major festival of Asklēpiós in Athens: the one during the Greater Dionysia. The day was named after Asklēpiós' healing centre to the south at Epidauros. It was said that on this day, the cult of Asklepios and Hygeia joined the Eleusinian Mysteries rites in Athens.

What, exactly, happened during the Epidauria is unclear as discussing the rites that took place at Eleusis carried a death sentence, but I think we can safely say that the rites at Eleusis involving Asklēpiós were most likely similar to the rites to Asklēpiós that took place at other places--including Epidauros. What we do know is that the evening rites of sacrifices were held at Demeter’s Eleusinion temple in Athens to honour Asklēpiós, His daughter Hygeia, and Demeter and Persephone, who also were revered as healing deities. Special blessings were invoked for doctors and healers, and perhaps healing practices were offered at Demeter’s Eleusinion temple.

Then started the part that we have to guestimate by way of other practices involving Asklēpiós. Asklēpiós' worship almost always included a 'night watch'; a night time period of meditation and contemplation at a temple to Asklēpiós; the Asklepion. the initiates would most likely sit, contemplate, and cleanse themselves of ailments, distress, and anything that might distract them form the proceedings to follow. The temple of Asklēpiós was built near the enclosure of a sacred spring in a small cave and it included an abaton, a sleeping hall sacred to Asklēpiós where initiates could sleep while watched over by priests of Asklēpiós who prayed to Asklēpiós to visit these initiates in their sleep and give them messages intended to heal and cleanse. The following morning, initiates would tell their dream to a priest of Asklēpiós or Hygeia, called 'therapeutes'. The initiate would then be encouraged to put the advice he or she had gotten into practice.

The Epidauria took place as a preparatory intermezzo: afterwards, the initiates were cleaned and focussed, ready to be drawn further into the Mysteries. As these proceedings took place late at night, a certain lack of sleep might also occur, leaving the initiates more susceptible to the coming proceedings. Whatever the case, the initiates would soon be enveloped in the hectic but highly ritualized proceedings of the Mysteries, and likely feel far more ready--and worthy--to face them.
