Ye who have yearned
With too much passion, will here stay and pity
For the mere sake of truth, as 'tis a ditty
Not of these days, but long ago 'twas told
By a cavern wind unto a forest old;
And then the forest told it in a dream
To a sleeping lake, whose cool and level gleam
A poet caught as he was journeying
To Phoebus' shrine; and in it he did fling
His weary limbs, bathing an hour's space,
And after, straight in that inspired place
He sang the story up into the air,
Giving it universal freedom.

John Keats, Endymion, Book II, 827
