But eruptions and earthquakes, though the most tremendous, are not the only phenomena of volcanic regions which have affected the religion of the inhabitants. Poisonous mephitic vapours and hot springs, which abound especially in volcanic regions,[611] have also had their devotees, and both are, or were formerly, to be found in those western districts of Asia Minor with which we are here concerned. To begin with vapours, we may take as an illustration of their deadly effect the Guevo Upas, or Valley of Poison, near Batur in Java. It is the crater of an extinct volcano, about half a mile in circumference, and from thirty to thirty-five [pg 204] feet deep. Neither man nor beast can descend to the bottom and live. The ground is covered with the carcases of tigers, deer, birds, and even the bones of men, all killed by the abundant emanations of carbonic acid gas which exhale from the soil. Animals let down into it die in a few minutes. The whole range of hills is volcanic. Two neighbouring craters constantly emit smoke.[612] In another crater of Java, near the volcano Talaga Bodas, the sulphureous exhalations have proved fatal to tigers, birds, and countless insects; and the soft parts of these creatures, such as fibres, muscles, hair, and skin, are well preserved, while the bones are corroded or destroyed.[613]
Places of Pluto or Charon. The valley of Amsanctus.
The ancients were acquainted with such noxious vapours in their own country, and they regarded the vents from which they were discharged as entrances to the infernal regions.[614] The Greeks called them places of Pluto (Plutonia) or places of Charon (Charonia).[615] In Italy the vapours were personified as a goddess, who bore the name of Mefitis and was worshipped in various parts of the peninsula.[616] She had a temple in the famous valley of Amsanctus in the land of the Hirpini, where the exhalations, supposed to be the breath of Pluto himself, were of so deadly a character that all who set foot on the spot died.[617] The place is a glen, partly wooded with chestnut trees, among limestone hills, distant about four miles from the town of Frigento. Here, under a steep shelving bank of decomposed limestone, there is a pool of dark ash-coloured water, which continually bubbles up with an explosion like distant thunder. A rapid stream of the same blackish water rushes into the pool from under the [pg 205] barren rocky hill, but the fall is not more than a few feet. A little higher up are apertures in the ground, through which warm blasts of sulphuretted hydrogen are constantly issuing with more or less noise, according to the size of the holes. These blasts are no doubt what the ancients deemed the breath of Pluto. The pool is now called Mefite and the holes Mefitinelle. On the other side of the pool is a smaller pond called the Coccaio, or Cauldron, because it appears to be perpetually boiling. Thick masses of mephitic vapour, visible a hundred yards off, float in rapid undulations on its surface. The exhalations given off by these waters are sometimes fatal, especially when they are borne on a high wind. But as the carbonic acid gas does not naturally rise more than two or three feet from the ground, it is possible in calm weather to walk round the pools, though to stoop is difficult and to fall would be dangerous. The ancient temple of Mefitis has been replaced by a shrine of the martyred Santa Felicita.[618]
Sanctuaries of Charon or Pluto in Caria.
Similar discharges of poisonous vapours took place at various points in the volcanic district of Caria, and were the object of superstitious veneration in antiquity. Thus at the village of Thymbria there was a sacred cave which gave out deadly emanations, and the place was deemed a sanctuary of Charon.[619] A similar cave might be seen at the village of Acharaca near Nysa, in the valley of the Maeander. Here, below the cave, there was a fine grove with a temple dedicated to Pluto and Persephone. The place was sacred to Pluto, yet sick people resorted to it for the restoration of their health. They lived in the neighbouring village, and the priests prescribed for them according to the revelations which they received from the two deities in dreams. Often the priests would take the patients to the cave and leave them there for days without food. Sometimes the sufferers themselves were favoured with revelations in dreams, but [pg 206] they always acted under the spiritual direction of the priests. To all but the sick the place was unapproachable and fatal. Once a year a festival was held in the village, and then afflicted folk came in crowds to be rid of their ailments. About the hour of noon on that day a number of athletic young men, their naked bodies greased with oil, used to carry a bull up to the cave and there let it go. But the beast had not taken a few steps into the cavern before it fell to the ground and expired: so deadly was the vapour.[620]
Sanctuary of Pluto at the Lydian or Phrygian Hierapolis.
Another Plutonian sanctuary of the same sort existed at Hierapolis, in the upper valley of the Maeander, on the borders of Lydia and Phrygia.[621] Here under a brow of the hill there was a deep cave with a narrow mouth just large enough to admit the body of a man. A square space in front of the cave was railed off, and within the railing there hung so thick a cloudy vapour that it was hardly possible to see the ground. In calm weather people could step up to the railing with safety, but to pass within it was instant death. Bulls driven into the enclosure fell to the earth and were dragged out lifeless; and sparrows, which spectators by way of experiment allowed to fly into the mist, dropped dead at once. Yet the eunuch priests of the Great Mother Goddess could enter the railed-off area with impunity; nay more, they used to go up to the very mouth of the cave, stoop, and creep into it for a certain distance, holding their breath; but there was a look on their faces as if they were being choked. Some people ascribed the immunity of the priests to the divine protection, others to the use of antidotes.[622]
