But if the latter supposition could be admissible, did he use his agents only to betray them afterwards to exposure, and that, without any possible clew to his own detection as the instigator? Then, there came over me confused recollections of tales of mediaeval witchcraft, which I had read in boyhood. Were there not on judicial record attestation and evidence, solemn and circumstantial, of powers analogous to those now exercised by Margrave,--of sorcerers instigating to sin through influences ascribed to Demons; making their apparitions glide through guarded walls, their voices heard from afar in the solitude of dungeons or monastic cells; subjugating victims to their will, by means which no vigilance could have detected, if the victims themselves had not confessed the witchcraft that had ensnared, courting a sure and infamous death in that confession, preferring such death to a life so haunted? Were stories so gravely set forth in the pomp of judicial evidence, and in the history of times comparatively recent, indeed to be massed, pell-mell together, as a moles indigesta of senseless superstition,--all the witnesses to be deemed liars; all the victims and tools of the sorcerers, lunatics; all the examiners or judges, with their solemn gradations--lay and clerical--from Commissions of Inquiry to Courts of Appeal,--to be despised for credulity, loathed for cruelty; or, amidst records so numerous, so imposingly attested, were there the fragments of a terrible truth? And had our ancestors been so unwise in those laws we now deem so savage, by which the world was rid of scourges more awful and more potent than the felon with his candid dagger? Fell instigators of the evil in men's secret hearts, shaping into action the vague, half-formed desire, and guiding with agencies impalpable, unseen, their spell-bound instruments of calamity and death.
