The Egyptians embalmed their dead, and the processes which they employed were sufficiently perfect to secure them an indefinite preservation. This is a fact of which the pyramids, the caverns, and all the sepultures of Egypt offer us irrefragible proofs. But what were the causes and the origin of this custom? We have in answer to this question only hypothesis and conjecture. In the absence of valid documents, each one explains according to the bias of his mind, or the nature of his studies, a usage, the origin of which is lost in the night of time. One of the ancients informs us that the Egyptians took so much pains for the preservation of the body, believing that the soul inhabited it so long as it subsisted. Cassien, on the other hand, assures us that they invented this method because they were unable to bury their dead during the period of inundation. Herodotus, in his third book, observes, that embalming had for its object the securing of bodies from the voracity of animals; _they did not bury them_, says he, _for fear they would be eaten by worms, and they did not burn them, because they considered fire like a wild beast that devours everything it can seize upon_. Filial piety and respect for the dead, according to Diodorus Sicculus, were the sentiments which inspired the Egyptians with the idea of embalming the dead bodies. De Maillet, in his tenth letter upon Egypt, refers only to a religious motive the origin of embalming: “The priests and sages of Egypt taught their fellow citizens that, after a certain number of ages, which they made to amount to thirty or forty thousand years, and at which they fixed the epoch of the great revolution when the earth would return to the point at which it commenced its existence, their souls would return to the same bodies which they formerly inhabited. But, in order to arrive, after death, to this wished for resurrection, two things were absolutely necessary; first, that the bodies should be absolutely carefully preserved from corruption, in order that the souls might re-inhabit them; secondly, that the penance submitted to during this long period of years, that the numerous sacrifices founded by the dead, or those offered to their manes by their relations or their friends, should expiate the crimes they had committed during the time of their first habitation on earth. With these conditions exactly observed, these souls, separated from their bodies, should be permitted to re-enter at the arrival of this grand revolution which they anticipated--remember all that had passed during their first sojourn, and become immortal like themselves. They had further the privilege of communicating this same happiness to the animals which they had cherished, provided that their bodies inclosed in the same tomb with themselves, were equally well preserved. It is in virtue of this belief that so many birds, cats, and other animals are found embalmed with almost the same care as the human bodies with
