Herodotus is our chief authority for the few circumstances recounted of this impostor's life and deeds, and those few circumstances, like so many other wonderful things told of by the "Father of History," must be taken _cum granô salis_. It is very difficult to distinguish the facts of so remote a period of the world's history as was the epoch of Smerdis from the fable, and the safer plan is to accept all such records, not strongly corroborated by a conformity of contemporary opinion, as pure fiction, or as merely symbolic. The migrations and conquests of prehistoric peoples, as displayed by their philological and ethnological remains, are far more reliable evidence than are fables of the partial, or purposely misleading so-called "historians" of antiquity, whose writings generally are little better than collections of allegorical folk-lore. The story of the pseudo Smerdis, with these qualifying reservations, may be narrated thus:--Cyrus, the founder of the Persian empire, left his extensive possessions to his eldest son, Cambyses. This monarch, whom it has been sought to identify with the Ahasuerus of Scripture, commenced his reign with a great display of energy and warlike spirit, but would appear to have incensed the priesthoods of the different countries under his sway by manifesting an utter contempt for their rites, and by deriding their ceremonies. Urged by an insatiable ambition, he made war upon Egypt, added it to his already overgrown empire, and then, with his vast hordes of soldiery, overran the greater portion of North Africa. Not, however, possessing the ability or means of swaying such extended domains, he found himself, after his armies had suffered most frightful loss of life, compelled to retreat from Ethiopia and to return to Egypt. Arriving in this latter country about the period of the festivals held in honour of Apis, he is stated to have slain the sacred bull, under which form the god was symbolically worshipped, and in consequence of the sacrilegious deed, was punished with insanity. Previous to this catastrophe, in a fit of jealousy, he had sent his only brother Smerdis back to Persia; and now his suspicions as to the good faith of his nearest relative and heir were intensified by a dream he had, in which he imagined that a courier had arrived from Persia to inform him that Smerdis had usurped the Persian throne. Filled with dread, Cambyses sent for Prexaspes, his most faithful servitor, and persuaded him to undertake the assassination of Smerdis. During the absence of his envoy, and whilst under the influence of frightful attacks of mental aberration, he committed the most terrible cruelties, amongst the crimes enumerated by the historian being the brutal murder of his sister, whom he had espoused; the slaying of the son of his favourite, Prexaspes, and the burying alive--head downwards--of twelve of the principal noblemen of his court.
