Shelley, Prometheus Unbound

On a poet's lips I slept
Dreaming like a love-adept
In the sound his breathing kept;
Nor seeks nor finds he mortal blisses,
But feeds on the aëreal kisses
Of shapes that haunt thought's wildernesses.
He will watch from dawn to gloom
The lake-reflected sun illume
Than yellow bees in the ivy-bloom,
Nor heed nor see, what things they be;
But from these create he can
Forms more real than living man,
Nurslings of immortality!
One of these awakened me,
And I sped to succour thee.

(PU, I, 736-751)
