When the last bolt had yielded to the key, the guardians and the reverend archbishop again entreated the king to pause and reflect. “Whatever is within this tower,” said they, “is as yet harmless, and lies bound under a mighty spell: venture not then to open a door which may let forth a flood of evil upon the land.” But the anger of the king was roused, and he ordered that the portal should be instantly thrown open. In vain, however, did one after another exert his strength; and equally in vain did the cavaliers unite their forces, and apply their shoulders to the gate: though there was neither bar nor bolt remaining, it was perfectly immoveable. The patience of the king was now exhausted, and he advanced to apply his hand; scarcely, however, did he touch the iron gate, when it swung slowly open, uttering, as it were, a dismal groan, as it turned reluctantly upon its hinges. A cold, damp wind issued forth, accompanied by a tempestuous sound. The hearts of the ancient guardians quaked within them, and their knees smote together; but several of the youthful cavaliers rushed in, eager to gratify their curiosity, or to signalise themselves in this redoubtable enterprise. They had scarcely advanced a few paces, however, when they recoiled, overcome by the baleful air, or by some fearful vision.[12] Upon this, the king ordered that fires should be kindled to dispel the darkness, and to correct the noxious and long imprisoned air: he then led the way into the interior; but, though stout of heart, he advanced with awe and hesitation. After proceeding a short distance, he entered a hall, or antechamber, on the opposite side of which was a door; and before it, on a pedestal, stood a gigantic figure, of the colour of bronze, and of a terrible aspect. It held a huge mace, which it whirled incessantly, giving such cruel and resounding blows upon the earth as to prevent all further entrance. The king paused at sight of this appalling figure; for whether it were a living being, or a statue of magic artifice, he could not tell. On its breast was a scroll, whereon was inscribed in large letters, “I do my duty.”[13] After a little while Roderick plucked up heart, and addressed it with great solemnity: “Whatever thou be,” said he, “know that I come not to violate this sanctuary, but to inquire into the mystery it contains; I conjure thee, therefore, to let me pass in safety.” Upon this the figure paused with uplifted mace, and the king and his train passed unmolested through the door.
