Among the hills a meteorite 
Lies huge; and moss has overgrown, 
And wind and rain with touches light 
Made soft, the contours of the stone. 
 
Thus easily can Earth digest 
A cinder of sidereal fire, 
And make her translunary guest 
The native of an English shire. 
 
Nor is it strange these wanderers 
Find in her lap their fitting place, 
For every particle that's hers 
Came at the first from outer space. 
 
All that is Earth has once been sky; 
Down from the sun of old she came, 
Or from some star that travelled by 
Too close to his entangling flame. 
 
Hence, if belated drops yet fall 
From heaven, on these her plastic power 
Still works as once it worked on all 
The glad rush of the golden shower.
Clive Staples Lewis
