We now found ourselves in a deep, narrow ravine, filled with beautiful groves, with a steep avenue and various footpaths winding through it, bordered with stone seats and ornamented with fountains. To our left, we beheld the towers of the Alhambra beetling above us; to our right, on the opposite side of the ravine, we were equally dominated by rival towers on a rocky eminence. These, we were told, were the Torres Vermejos, or Vermilion towers, so called from their ruddy hue. No one knows their origin. They are of a date much anterior to the Alhambra. Some suppose them to have been built by the Romans; others, by some wandering colony of Phoenicians. Ascending the steep and shady avenue, we arrived at the foot of a huge square Moorish tower, forming a kind of barbican, through which passed the main entrance to the fortress. This portal is called the Gate of Justice, from the tribunal held within its porch during the Moslem domination, for the immediate trial of petty causes; a custom common to the Oriental nations, and occasionally alluded to in the sacred Scriptures. [Illustration: THE GATE OF JUSTICE] The great vestibule, or porch of the gate, is formed by an immense Arabian arch of the horseshoe form, which springs to half the height of the tower. On the keystone of this arch is engraven a gigantic hand. Within the vestibule, on the keystone of the portal, is engraven, in like manner, a gigantic key. Those who pretend to some knowledge of Mohammedan symbols affirm that the hand is the emblem of doctrine, and the key of faith; the latter, they add, was emblazoned on the standard of the Moslems when they subdued Andalusia, in opposition to the Christian emblem of the cross. It was a tradition handed down from the oldest inhabitants, and which our informant had from his grandfather, that the hand and key were magical devices on which the fate of the Alhambra depended. The Moorish king who built it was a great magician, and, as some believed, had sold himself to the devil, and had laid the whole fortress under a magic spell. By this means it had remained standing for several hundred years, in defiance of storms and earthquakes, while almost all the other buildings of the Moors had fallen to ruin and disappeared. The spell, the tradition went on to say, would last until the hand on the outer arch should reach down and grasp the key, when the whole pile would tumble to pieces, and all the treasures buried beneath it by the Moors would be revealed.
