Loitering with a vacant eye  
Along the Grecian gallery,  
And brooding on my heavy ill,  
I met a statue standing still.  
Still in marble stone stood he,  
And stedfastly he looked at me.  
"Well met," I thought the look would say,  
"We both were fashioned far away;  
We neither knew, when we were young,  
These Londoners we live among."  
 
Still he stood and eyed me hard,  
An earnest and a grave regard:  
"What, lad, drooping with your lot?  
I too would be where I am not.  
I too survey that endless line  
Of men whose thoughts are not as mine.  
Years, ere you stood up from rest,  
On my neck the collar prest;  
Years, when you lay down your ill,  
I shall stand and bear it still.  
Courage, lad, 'tis not for long:  
Stand, quit you like stone, be strong."  
So I thought his look would say;  
And light on me my trouble lay,  
And I stept out in flesh and bone  
Manful like the man of stone.
Alfred Edward Housman
