To the same manner of explaining striking appearances in physical geography, and especially strange rocks and boulders, we mainly owe the innumerable stories of the transformation of living beings, and especially of men and women, into these natural features.

In the mythology of China we constantly come upon legends of such transformations—from that of the first Counsellor of the Han dynasty to those of shepherds and sheep. In the Brahmanic mythology of India, Salagrama, the fossil ammonite, is recognised as containing the body of Vishnu's wife, and the Binlang stone has much the same relation to Siva; so, too, the nymph Ramba was changed, for offending Ketu, into a mass of sand; by the breath of Siva elephants were turned into stone; and in a very touching myth Luxman is changed into stone but afterward released. In the Buddhist mythology a Nat demon is represented as changing himself into a grain of sand.

Among the Greeks such transformation myths come constantly before us—both the changing of stones to men and the changing of men to stones. Deucalion and Pyrrha, escaping from the flood, repeopled the earth by casting behind them stones which became men and women; Heraulos was changed into stone for offending Mercury; Pyrrhus for offending Rhea; Phineus, and Polydectes with his guests, for offending Perseus: under the petrifying glance of Medusa's head such transformations became a thing of course.

To myth-making in obedience to the desire of explaining unusual natural appearances, coupled with the idea that sin must be followed by retribution, we also owe the well-known Niobe myth. Having incurred the divine wrath, Niobe saw those dearest to her destroyed by missiles from heaven, and was finally transformed into a rock on Mount Sipylos which bore some vague resemblance to the human form, and her tears became the rivulets which trickled from the neighbouring strata.

Thus, in obedience to a moral and intellectual impulse, a striking geographical appearance was explained, and for ages pious Greeks looked with bated breath upon the rock at Sipylos which was once Niobe, just as for ages pious Jews, Christians, and Mohammedans looked with awe upon the salt pillar at the Dead Sea which was once Lot's wife.

Pausanias, one of the most honest of ancient travellers, gives us a notable exhibition of this feeling. Having visited this monument of divine vengeance at Mount Sipylos, he tells us very naively that, though he could discern no human features when standing near it, he thought that he could see them when standing at a distance. There could hardly be a better example of that most common and deceptive of all things—belief created by the desire to believe.

In the pagan mythology of Scandinavia we have such typical examples as Bors slaying the giant Ymir and transforming his bones into boulders; also "the giant who had no heart" transforming six brothers and their wives into stone; and, in the old Christian mythology, St. Olaf changing into stone the wicked giants who opposed his preaching.

So, too, in Celtic countries we have in Ireland such legends as those of the dancers turned into stone; and, in Brittany, the stones at Plesse, which were once hunters and dogs violating the sanctity of Sunday; and the stones of Carnac, which were once soldiers who sought to kill St. Cornely.

Teutonic mythology inherited from its earlier Eastern days a similar mass of old legends, and developed a still greater mass of new ones. Thus, near the Konigstein, which all visitors to the Saxon Switzerland know so well, is a boulder which for ages was believed to have once been a maiden transformed into stone for refusing to go to church; and near Rosenberg in Mecklenburg is another curiously shaped stone of which a similar story is told. Near Spornitz, in the same region, are seven boulders whose forms and position are accounted for by a long and circumstantial legend that they were once seven impious herdsmen; near Brahlsdorf is a stone which, according to a similar explanatory myth, was once a blasphemous shepherd; near Schwerin are three boulders which were once wasteful servants; and at Neustadt, down to a recent period, was shown a collection of stones which were once a bride and bridegroom with their horses—all punished for an act of cruelty; and these stories are but typical of thousands.

At the other extremity of Europe we may take, out of the multitude of explanatory myths, that which grew about the well-known group of boulders near Belgrade. In the midst of them stands one larger than the rest: according to the legend which was developed to account for all these, there once lived there a swineherd, who was disrespectful to the consecrated Host; whereupon he was changed into the larger stone, and his swine into the smaller ones. So also at Saloniki we have the pillars of the ruined temple, which are widely believed, especially among the Jews of that region, to have once been human beings, and are therefore known as the "enchanted columns."
