Hundreds and thousands of times had he heard that same sound in the city. But hundreds and thousands of times, it seemed to him, he had not comprehended it.
It was an immeasurably glorious and transporting sound. As deep and rumbling as, and more powerful than, any sound on earth. The voice of the ocean when it is angry, the voice of falling torrents, the voice of very close thunder-storms would be miserably drowned in this Behemoth-din. Without being shrill it penetrated all walls, and, as long as it lasted, all things seemed to swing in it. It was omnipresent, coming from the heights and from the depths, being beautiful and horrible, being an irresistible command.
It was high above the town. It was the voice of the town.
Metropolis raised her voice. The machines of Metropolis roared; they wanted to be fed.
Freder pushed open the glass doors. He felt them tremble like strings under strokes of the bow. He stepped out on to the narrow gallery which ran around this, almost the highest house of Metropolis. The roaring sound received him, enveloped him, never coming to an end.
Great as Metropolis was: at all four corners of the city, this roared command was equally perceptible.
Freder looked across the city at the building known to the world as the “New Tower of Babel.”
In the brain-pan of this New Tower of Babel lived the man who was himself the Brain of Metropolis.
As long as the man over there, who was nothing but work, despising sleep, eating and drinking mechanically, pressed his fingers on the blue metal plate, which apart from himself, no man had ever touched, so long would the voice of the machine-city of Metropolis roar for food, for food, for food....
She wanted living men for food.
