§ Akallabêth The Silmarillion

Now the lightnings increased and slew men upon the hills, and in the fields, and in the streets of the city; and a fiery bolt smote the dome of the Temple and shore it asunder, and it was wreathed in flame. But the Temple itself was unshaken, and Sauron stood there upon the pinnacle and defied the lightning and was unharmed; and in that hour men called him a god and did all that he would. When therefore the last portent came they heeded it little. For the land shook under them, and a groaning as of thunder underground was mingled with the roaring of the sea, and smoke issued from the peak of the Meneltarma. But all the more did Ar-Pharazôn press on with his armament.
