Mithlond -Cool picture! The Tower on the left is obviously
Minas Morgul (formerly
Minas Ithil) "
Tower of the Rising Moon" and the other is
Orthanc, which means "Mount Fang", and "the Cunning Mind".
From "The Stairs of
Cirith Ungol".......
"....Upon the further side, some way within the valley's arms, high on a rocky seat upon the black knees of the Ephel Duath, stood the
walls and tower of Minas Morgul. All was dark about it, earth and sky, but it was lit with light. Not the imprisoned moonlight welling through the marbled walls of Minas Ithil long ago,
Tower of the Moon, fair and radiant in the hollow of the
hills. Paler indeed than the moon ailing in some slow eclipse was the lightn of it now, wavering and blowing like a noisome exhalation of decay, a corpse-light, a light that illuminated nothing. In the walls and tower windows showed, like countless black holes looking inward into emptiness; but the topmost course of the tower revolved slowly, first one way and then the other, a huge ghostly head leering into the night."
Then the three pass the bridge and go up the path, and while they rest there is a tumult in the earth and a great red flash in
the east, then came a great crack of thunder:
"And Minas Morgul answered. There was a flare of livid lightnings: forks of blue flame springing up from the tower and from the encircling hills into the sullen clouds. The earth groaned; and out of the
city there came a cry. Mingled with harsh high voices as of
birds of prey, and the shrill neighing of
horses wild with rage and fear, there came a rending screech, shivering, rising swiftly to a piercing pitch beyond the range of hearing............And out of the gate an army came.........Before them went a great cavalry of horsemen moving like ordered shadows, and at their head was one greater than all the rest: a Rider, all black, save that on his hooded head he had a
helm like a crown that flickered with a perilous light............Here indeed was the haggard king whose cold hand had smitten down the Ringbearer with his deadly
knife."
Then they stop and he tries to sense
Frodo, then move on again, to war with
Gondor.
Isn't that a major event in TTT? I think this must be the other "Tower" in the title.
