Excerpt from Epiphanios of Eleutheroupolis

In Alexandria there is the so-called Korion, and it is a very large temple, that is the temenos of Kore. (The worshippers) having passed the night in vigilance with songs and flute playing, singing to the idol …. After the call of the roosters they descend with torches in hand to an underground chamber and from it they bring up on a litter a wooden xoanon, seated, nude, bearing on its forehead some seal of a cross, covered with gold … and they carry this xoanon around seven times, making a circle around the most central temple with flutes and drums and hymns, and having sang and danced they take it down again to the underground place … and they say that at this hour, today the Kore, that is the Virgin, gave birth to the Aion.
