The youth put the letter in his bosom. 'Trust me, lady,' said he, 'I will neither halt nor turn aside, nor cast a look behind, until I reach Count Julian.' He mounted his fleet steed, sped his way across the bridge, and soon left behind him the verdant valley of the Tagus. * * * * * The heart of Don Roderick was not so depraved by sensuality, but that the wrong he had been guilty of toward the innocent Florinda, and the disgrace he had inflicted on her house, weighed heavy on his spirits, and a cloud began to gather on his once clear and unwrinkled brow. Heaven, at this time, say the old Spanish chronicles, permitted a marvellous intimation of the wrath with which it intended to visit the monarch and his people, in punishment of their sins; nor are we, say the same orthodox writers, to startle, and withhold our faith, when we meet in the page of discreet and sober history with these signs and portents, which transcend the probabilities of ordinary life; for the revolutions of empires and the downfall of mighty kings are awful events, that shake the physical as well as the moral world, and are often announced by forerunning marvels and prodigious omens. With such-like cautious preliminaries do the wary but credulous historiographers of yore usher in a marvellous event of prophecy and enchantment, linked in ancient story with the fortunes of Don Roderick, but which modern doubters would fain hold up as an apocryphal tradition of Arabian origin. Now, so it happened, according to the legend, that about this time, as King Roderick was seated one day on his throne, surrounded by his nobles, in the ancient city of Toledo, two men of venerable appearance entered the hall of audience. Their snowy beards descended to their breasts, and their gray hairs were bound with ivy. They were arrayed in white garments of foreign or antiquated fashion, which swept the ground, and were cinctured with girdles, wrought with the signs of the zodiac, from which were suspended enormous bunches of keys of every variety of form. Having approached the throne and made obeisance: 'Know, O King,' said one of the old men, 'that in days of yore, when Hercules of Libya, surnamed the strong, had set up his pillars at the ocean strait, he erected a tower near to this ancient city of Toledo. He built it of prodigious strength, and finished it with magic art, shutting up within it a fearful secret, never to be penetrated without peril and disaster. To protect this terrible mystery he closed the entrance to the edifice with a ponderous door of iron, secured by a great lock of steel; and he left a command that every king who should succeed him should add another lock to the portal; denouncing wo and destruction on him who should eventually unfold the secret of the tower.
