Hear the voice of the Bard !
Who present, past, and future sees;
Whose ears have heard
The Holy Word,
That walked among the ancient trees,

Calling the lapsed soul,
And weeping in the evening dew;
That might control
The starry pole,
And fallen, fallen, light renew!

'O Earth, O Earth, return!
Arise from out the dewy grass;
Night is worn,
And the morn
Rises from the slumberous mass.

'Turn away no more;
Why wilt thou turn away?
The starry floor,
The watery shore,
Is given thee till the break of day.'

William Blake
