‘I am the daughter of Earth and Water, 
And the nursling of the Sky; 
I pass through the pores of the ocean and shores; 
I change, but I cannot die. 
For after the rain when with never a stain 
The pavilion of Heaven is bare, 
And the winds and sunbeams with their convex gleams 
Build up the blue dome of air, 
I silently laugh at my own cenotaph, 
And out of the caverns of rain, 
Like a child from the womb, like a ghost from the tomb, 
I arise and unbuild it again.’ 

From ‘The Cloud’, in Prometheus Unbound (1820), by the English Romantic poet Percy Bysshe Shelley.
