The Guanches, with the Egyptians, are the only nation among whom embalming had become national, and there exists in the process and mode of preservation of both such striking analogy, that the study of the Guanch mummies is, probably, the surest means of arriving at some positive notions of their origin and relationship. To make ourselves understood in the subject which now occupies us, we ought to remark, that the details known of the mode of embalming among the Guanches, will enlighten and complete the descriptions that ancient authors have transmitted to us of the Egyptian processes: it is thus that it appears to us without a doubt, that their silence on desiccation in the act of mummification, is a simple omission on their part: that this desiccation was continued during the seventy days of preparation; that it constituted the principal part of the processes adopted; and that, because among the Guanches desiccation was placed in the first rank, if we are to credit the relations of authors. We see in this, one of the finest examples of the utility of the comparative study of the manners and usages of different nations: light is thrown on both by the comparison of facts. The pains taken by the Guanches to evaporate the fluid parts of their dead bodies, is the cause which determines us to place their mummies immediately after those of the deserts of Lybia; because their processes approach nearest to that of nature. The details which we are about to give, are extracted from the excellent work of M. Bory de Saint Vincent on the Fortunate Isles. “The arts of the Guanches were not numerous, the most singular without doubt is that of embalming. “The Guanches preserved the remains of their relations in a scrupulous manner, and spared no pains to guarantee them from corruption. As a moral duty, each individual prepared for himself the skins of goats, in which his remains could be enveloped, and which might serve him for sepulture. These skins were often divested of their hair, at other times they permitted it to remain, when they placed indifferently the hairy side within or without. The processes to which they resorted to make perfect mummies, which they named _xaxos_, are nearly lost. Some writers have, nevertheless, left details on this subject, but perhaps they are not more exact than those which Herodotus has transmitted to us upon the embalming of the Egyptians.
