The most remarkable feature of all in the Bacchic orgies is said to have been the mystic serpent. "The mystery of religion was throughout the world concealed in a chest or box. As the Israelites had their sacred ark, every nation upon earth had some holy receptacle for sacred things and symbols. The story of Ericthonius is illustrative of this remark. He was the fourth King of Athens, and his body terminated in the tails of serpents, instead of legs. He was placed by Minerva in a basket, which she gave to the daughter of Cecrops, with strict injunctions not to open it. Here we have a fable made out of the simple fact of the mysterious basket, in which the sacred serpent was carried at the orgies of Bacchus. The whole legend relates to Ophiolatreia. In accordance with the general practice, the worshippers of Bacchus carried in their consecrated baskets or chests the Mystery of their God, together with the offerings."[17] At the banquets of the Bacchantes, or rather, after them, it was usual to carry round a cup, which was called the "cup of the good dæmon." The symbol of this dæmon was a serpent, as seen on the medals of the town of Dionysopolis in Thrace. On one side were the heads of Gordian and Serapis on the other a coiled serpent. The serpent was mixed up to a considerable extent with the worship of many other of the Grecian deities. The statues, by Phidias, of Minerva, represent her as decorated with this emblem. In ancient medals, as shown by Montfaucon, she sometimes holds a caduceus in her right hand; at other times she has a staff around which a serpent is twisted, and at others, a large serpent appears going in front of her; while she is sometimes seen with her crest composed of a serpent. It is remarkable too, that in the Acropolis at Athens was kept a live serpent who was generally considered the guardian of the place, and Athens was a city specially consecrated to Minerva. Examples of Grecian Ophiolatreia might easily be multiplied to a considerable extent, but we have space for little more than a brief glance. It is known that upon the walls of Athens was a sculptured head of Medusa, whose hair was intertwined with snakes, and in the temple at Tega was a similar figure which was supposed to possess talismanic power to preserve or destroy. The print in Montfaucon represents the face of Medusa as mild and beautiful, but the serpents as threatening and terrible. There is a story current, that a priestess going into a sanctuary of Minerva in the dead of the night, saw a vision of that goddess, who held up her mantle upon which was impressed a Medusa's head, and that the sight of this fearful object instantaneously converted the intruder into stone. The armour of Agamemnon, king of Argos, was ornamented with a three headed serpent; Menelaus, king of Sparta, had one on his shield, and the Spartan people, with the Athenians, affirmed they were of serpentine origin and called themselves _ophiogenæ_.
