Not The Vandal Who Ravaged Gaul

Faded in gold, "Mercury" graffiti.    
I had left behind a storefront branded    
With names that did not matter to me.    
Yet, the matter that clung here,    
Vapor of what was left    
of what the concrete was keeping    
Gold paint through paint seeping    
upon the alley wall, vestiges      
from the past. No longer all here.    
But the echoes that reverberate, in smoke,    
do so with our hopes and fears.    
In the reflection of the glass shards    
beneath me, I saw the mirrored wall    
of the alley behind me and strewn across    
the bricks again, but vivid in color;       
Brilliant, this time, in gold, "Mercury" graffiti.
