The opinion of Volney, revived and adopted by Pariset, in his memoir on the causes of the plague, is closely allied to the preceding. “In a numerous population, under a burning climate, and a soil profoundly drenched during many months of the year, the rapid putrefaction of bodies is a leaven for plague and disease. Stricken by these murderous pests, Egypt, at an early day, struggled to obviate them; hence have arisen, on the one hand, the custom of burying their dead at a distance from their habitations; and on the other, an art so ingenious and simple, to prevent putrefaction by embalming: a secondary precaution, more important and more efficacious, with which the primary could not dispense, and which, exacting attempts, trials, and experiments, could only be obtained as a last result--an art by no means expensive, of a simplicity and facility of execution, which rendered its immediate application popular, general, and, perhaps, uniform for all dead bodies. Research and luxury followed at a later period.” The sentiments to which the authors above cited attribute the origin of embalming among the Egyptians exist in every man, viewed either as a social or isolated being. One individual may be induced to embalm the bodies of his relatives or friends by motives of superstition; another from egotism or personal interest; a third from motives of salubrity or common interest; another, in fine, is impelled by an instinctive affection to perform the sacred duty of preserving the remains of those who were dear to him. But none of these motives possess a character of generality and perpetuity, which consecrates a usage and renders it popular; it was therefore left to government to interfere and give it the force of law. The noble sentiments of affection, of respect, and of veneration, had then, without doubt, the priority; and everything proves to us that these inspired the admirable art of embalming, and that they were above all invoked by legislators. Nature, besides, upon this torrid soil, gave the first idea of this mode of preserving the remains of men and animals: the mummy[1] of the sands, a natural phenomenon, was a revelation to a people so wise and industrious. The course of our work will demonstrate, we hope, the simple connection of these facts; it had already arrested M. le Comte de Caylus, who, in a memoir read to the Academy of Inscriptions and Belles-Lettres, in 1749, thus expresses himself: “The Egyptians, according to appearances, owe the idea of their mummies, to the dead bodies which they found buried in the burning sands which prevail in some parts of Egypt, and which, carried away by the winds, bury travellers and preserve their bodies, by consuming the fat and flesh without altering the skin.”
