A narrow passage was before him, scarcely rendered visible by the flickering light of a cresset suspended from the ceiling, and nourished, as it seemed, with spirit, rather than with the richer food of oil. Uncertain, however, as was the illumination, it served to show a second door, even more strongly constructed than the first, fronting the intruder at the distance of some ten paces; while the wall, perforated with loops for musketry, or more probably, if the remote antiquity of the building were considered, for arrows, proved that the hostile intruder had effected but little in forcing his way through the outward entrance. It would be wrong, in the description of this difficult passage, to omit the mention of certain orifices, or slits, extending in length from the floor even to the ceiling of the side-walls, but not exceeding a single inch in width, as they may tend perhaps to cast some light upon an invention of the darkest ages of Scottish history, the reality of which has been considered doubtful by acute antiquarians. From the upper extremity of these slits protruded on either side the blades of six enormous swords, which, being placed alternately, and worked by some concealed machinery, must inevitably hew to atoms, when once set in motion, any obstacle to their appalling sway. This was the dreaded swordmill first discovered by the wizard baron Soulis, and thence invested with superstitious error, which was needless, at the least, when the actual horrors of the engine were considered. It is, however, probable, that these gigantic relics of an earlier age were no longer capable of being rendered available at the period of which we write; at all events they hung in rusty blackness, suspended like the sword of Damocles above the head of the intruder, rendering his position awful, at least, if not in reality insecure. Notwithstanding the warlike and turbulent character of Scotland during the reign of Mary, there was nevertheless enough of the uncommon in the defences of this dark and dangerous entrance to have riveted the attention of a man less anxiously engaged than was the foreign cavalier. Apparently undismayed by the wild contrivances around him, the gallant strode forward to repeat his signal on the inner wicket, when a broad glare of crimson light, produced by some chemical preparation, considered in that dark age supernatural, was shot into his very face from an aperture above, clearly displaying to some concealed observer the form and features of his visiter. “Ha!” cried a voice so shrill and grating as to produce a painful impression on the nerves of the hearer. “Thou art come hither, Sir Italian; enter, then--enter in the name of Albunazar!--enter, the hour is propitious, and thou art waited for!”
