Titan! to whom immortal eyes
The sufferings of mortality
Seen in their sad reality,
Were not as things that gods despise;
What was thy pity's recompense?
A silent suffering, and intense;
The rock, the vulture, and the chain,
All that the proud can feel of pain,
The agony they do not show,
The suffocating sense of woe,
Which speaks but in its loneliness,
And then is jealous lest the sky
Should have a listener, nor will sigh
Until its voice is echoless.

I - Prometheus (1816)
