Classic Poem

Noise of hammers once I heard
Many hammers, busy hammers,
Beating, shaping, night and day,
Shaping, beating dust and clay
To a palace; saw it reared;
Saw the hammers laid away.

And I listened, and I heard
Hammers beating, night and day,
In the palace newly reared,
Beating it to dust and clay:
Other hammers, muffled hammers,
Silent hammers of decay.
