 The seawards initiates ("halade mystai") started out in Athens on 16th Boedromion with the celebrants washing themselves in the sea at Phaleron.On the 17th, the participants began the "Epidauria", a festival for Asklepios named after his main sanctuary at Epidauros.This "festival within a festival" celebrated the healer's arrival at Athens with his daughter Hygieia, and consisted of a procession leading to the Eleusinion, during which the mystai apparently stayed at home, a great sacrifice, and an all-night feast ("pannykhís").
