"They cannot conquer forever!"

There, far away, beyond sad Gondor now overwhelmed in shade, the Sun was sinking, finding at last the hem of the great slow-rolling pall of cloud, and falling in an ominous fire towards the yet unsullied Sea. The brief glow fell upon a huge sitting figure, still and solemn as the great stone kings of Argonath. The years had mocked it, and violent hands had maimed it. Its head was gone, and in its place was set in mockery a rough-hewn stone, rudely painted by savage hands in the likeness of a grinning face with one large red eye in the midst of its forehead. Upon its knees and mighty chair, and all about the pedestal, were idle scrawls mixed with the foul symbols that the maggot folk of Mordor used.

Suddenly, caught by the level beams, Frodo saw the old king's head: it was lying rolled away by the roadside. 'Look, Sam!' He cried, startled into speech. 'Look! The King has got a crown again!'

The eyes were hollow and the carven beard was broken, but about the high stern forehead there was a coronel of silver and gold. A trailing plant with flowers like small white stars had bound itself across the brows as if in reverence for the fallen king, and in the crevices of his stony hair yellow stonecrop gleamed.

'They cannot conquer forever!' said Frodo. And then suddenly the brief glimpse was gone. The Sun dipped and vanished, and as if at the shuttering of a lamp, black night fell.
