Types of Ombria (Fossil Sea Urchins). From Mercati’s “Metallotheca Vaticana,” Romæ, 1719.

If we were inclined to accord the title of precious stones to stones greatly esteemed for their talismanic virtues, a high place in this category would be assigned to the sâlagrâma-stone of the Hindus.[[403]] Among the aboriginal inhabitants of India this was regarded as a symbol of the female principle in nature, and of its representative the goddess Prakrti, and in the later Hindu belief the stone was looked upon as the special emblem of the god Vishnu, the “Preserver,” the second personage of the Hindu Trimurti. It is therefore ardently revered by those who are more especially devoted to the worship of Vishnu. These stones are fossil formations, either of ammonites or univalve mollusks of a spiral order, and consist of a number of spirals surrounding a circular, central perforation. They are generally the hardened filling of the shell itself, which has entirely weathered away. For the stone to be an effectual talisman, the diameter of the perforation should not exceed one-eighth of the total diameter of the sâlagrâma. The best specimens are said to be found in Nepal, on the upper course of the Gandakî, which flows into the Ganges from the north, and is called the Salagrama River, because the sacred stone is found in it.

There can be little doubt that we have here a substance similar to the fossils described by Pliny and his successors under the names brontia, ombria, ovum anguinum, and cornu ammonis, and it is most probable that in India, as in Europe, these fossils were believed to have fallen from heaven, and were associated with the thunderbolt. Hence they would be regarded by the Hindus as more especially sacred to Vishnu, who was originally a divinity representing the various forms of light, one of his manifestations being the lightning.

The sâlagrâmas must be carefully chosen, for not all of them are luck-bringing, some being bearers of ill-fortune. A black sâlagrâma brings fame to the owner, and a red one, a crown; but one with an unduly large perforation would cause dissension and strife in a family, one with irregularly formed spirals portends misfortune, and a brown one would bring to pass the death of its owner’s wife. Each faithful worshipper of Vishnu has one of these stones, but two may not be in the same house. To give away a sâlagrâma would be equivalent to casting away every prospect of good fortune. However, only one who belongs to the three highest castes is entitled to become an owner of the sacred stone, in which the very spirit of Vishnu is supposed to dwell; neither a Sudra nor a Pariah enjoys this privilege, which is also denied to women.

The sâlagrâma is carefully wrapped in linen cloths, and must be often washed and perfumed. The water with which it has been washed becomes a consecrated drink. The master of the house must adore the stone once each day, either in the morning or in the evening. As the sâlagrâma not only brings happiness in this world but also insures felicity in the future world, it is held over the dying Hindu while water is allowed to trickle through the orifice. This ceremony appears to have a certain analogy to the rite of extreme unction administered in the Catholic Church.

It is stated by Finn Magnusen that in Iceland, toward the beginning of the last century, he saw superstitious peasants carefully guard small stones of peculiar appearance in pretty bags filled with fine flour. They treated these stones with great reverence and either wore them on their persons or placed them in their beds or other furniture.[[404]]

The fossils known as brontiæ, ombriæ and chelonites were all believed to be antidotes for poison and also to make the wearer victorious over his enemies. Hence they were sometimes set in the pommels of swords. That these objects were equally potent in peace, is shown by the fact that Danish peasant women placed them in their milk pails to ward off the effects of any spell that might have been cast over the cow’s milk by a malevolent witch.[[405]]

David Reich notes the four kinds of astroites, or “victory stones,” given by De Boot; the first, marked with small stars; the second, with rose-like figures; the third, with wavy lines, like the convolutions of a worm; the fourth, with obscure and indefinite markings. To these varieties Reich adds a fifth, the convex side of which was marked with black crosses, while the other, flat side, showed larger crosses surrounded by circles; all these markings were so perfect that an artist could scarcely imitate them; this specimen he had set, with other precious gems, in a silver cross, the flat side of the fossil, at the back of the cross, being covered by a heart-shaped topaz.[[406]] These were all specimens of fossil coral.
