"At Saïs in the Temple of Minerva, beneath the Churche and neere unto the walle of Minerva, in a base Chappell, are standinge certayne greate brooches of stone, whereto is adioyninge a lowe place in manner of a Dungeon, couered over wyth a stone curiously wroughte, the vaute it selfe being on euery side carued with most exquisite arte, in biggnesse matching with that in Delos, which is called Trochoïdes. Herein euery one counterfayteth the shadowes of his owne affections and phantasies in the nyghte season, which the Aegyptians call Mysteryes; touchinge whiche, God forbid, I should aduenture to discouer so much as they vouchsafed to tell mee." In chapter i of the _Book of the Dead_, too, we encounter the phrase, "I look upon the hidden things in _Re-stau_"--an allusion to the ceremonies which were performed in the sanctuary of Seker, the god of death at Saqqara. These typified the birth and death of the sun-god, and were celebrated betwixt midnight and dawn. Again, in chapter cxxv of the _Book of the Dead_ (Papyrus of Ani) we read, "I have entered into _Re-stau_ [the other world of Seker, near Memphis] and I have seen the Hidden One [or mystery] who is therein." Chapter cxlviii (_Saïte Recension_) is to be recited "on the day of the new moon, on the sixth-day festival, on the fifteenth-day festival, on the festival of Uag, on the festival of Thoth, on the birthday of Osiris, on the festival of Menu, on the night of Heker, during the mysteries of Maāt, during the celebration of the mysteries of Akertet," and so forth. Herodotus, who was supposed to have been initiated into these mysteries, is righteously cryptic concerning them, and just as he has aroused our interest to fever heat he invariably sees fit to remark that his lips are sealed on the subject. But is there anything so very extraordinary in these terrible doings? Theosophists and others would lead us to suppose that in the gloomy crypts of Egypt weird spiritistic rites of evocation and magical ceremonies of dark import were gone through. What are the probabilities? The Greek Mysteries
