This explains what I meant to imply when I said that the megalithic idea and the incentive to mummify the dead are genetically related, the one to the other. The stone-tomb came into existence as a direct result of the importance attached to the corpse. This development defeated the very object that inspired it. The invention of the art of embalming was the logical outcome of the attempt to remedy this unexpected result.
As in the history of every similar happening elsewhere, necessity, or what these simple-minded people believed to be a necessity, was the “mother of invention.”
In the course of the following discussion it will be seen that the practice of mummification became linked up in another way with what may be called the megalithic traditions. The crudely-preserved body no longer retained any likeness to the person as his friends knew him when alive. A life-like stone statue was therefore made to represent him. Magical means (p. 42) were adopted to give life to the statue. Thus originated the belief that a stone might become the dwelling of a living person; and that a person when dead may become converted into stone. So insistent did this belief become that among more uncultured people, who borrowed Egyptian practices but were unable to make portrait statues, a rudely-shaped or even unhewn pillar of stone came to be regarded as the dwelling of the deceased.
Thus from being the mere device for the identification of the deceased the stone statue degenerated among less cultured people into an object even less like the dead man than his own crudely-made mummy. But the fundamental idea remained and became the starting point for that rich crop of petrifaction-myths and beliefs concerning men and animals living in stones.
Thus arose in Egypt, somewhere about 3000 B.C., the nucleus of the “heliolithic” culture-complex—mummification, megalithic architecture, and the making of idols, three practices most intimately and genetically linked one with the other. But it was the merest accident that the people amongst whom these customs developed, should also have been weavers of linen, workers in copper, worshippers of the sun and serpent, and practitioners of massage and circumcision.
