Theodore Roethke

The Adamant

Thought does not crush to stone.
The great sledge drops in vain.
Truth never is undone;
Its shafts remain.

The teeth of knitted gears
Turn slowly through the night,
But the true substance bears
The hammer's weight.

Compression cannot break
A center so congealed;
The tool can chip no flake:
The core lies sealed.
