May we not also attribute to the worship of stones some of the religious and funeral rites of antiquity? According to Porphyry, Pythagoras, on his arrival on the island of Crete, was purified with thunder-stones by the dactyl priests of Mount Ida. The Etruscans wore flint arrow-heads on their collars. They were sought after by the Magi, and the Indians gave them an honored place in their temples. According to Herodotus, the Arabs sealed their engagements by making an incision in their hands with a sharp stone; in Egypt the body of a corpse before being embalmed was opened with a flint knife; a similar implement was used by the Hebrews for the rite of circumcision; and it was also with cut stones that the priests of Cybele inflicted self-mutilation in memory of that of Atys. At Rome the stone hatchet was dedicated to Jupiter Latialis, and solemn treaties were ratified by the sacrifice of a pig, the throat of which was cut with a sharp flint. According to Virgil, this custom was handed down to the ancient Romans by the uncouth nation of the Equicoles. At the beginning of the Christian era., the heroes commemorated by Ossian still had in the centre of their shields a polished stone consecrated by the Druids, and a saga maintains that the _ceraunia_ assured certain victory to their owners. On the other side of the Atlantic, the Aztecs used obsidian blades for the sacrifices, in which hundreds of human victims perished miserably; and similar blades are used by the Guanches of Teneriffe to open the bodies of their chiefs after death. At the present day, the Albanian Palikares use pointed flints to cut the flesh off the shoulder-blade of a sheep with a view to seeking in its fibres the secrets of the future, and when the god Gimawong visits his temple of Labode, on the western coast of Africa, his worshippers offer him a bull slain with a stone knife. Lumholtz,23 in the second of his recent explorations in Queensland, tells us that the natives still use stone weapons, varying in form and in the handles used, and that the weapons of the Australians living near Darling River, as well as those of the Tasmanians, are without handles.
