the man, the cave, the caveman

the cave  
   
found behind the boulder  
his trust, the secrets he'd told her  
trusting    
for rock's not the rusting  
to hold his treasure  
yet to no good measure  
   
the man  
   
the recluse  
the withdrawn  
the old man  
screamed    
from his heart  
the long drawn echoes  
of the cave  
his solace  
his joy  
his pages  
on the book  
of vibrations  
he rendered  
   
   
the caveman  
   
   
for he knew  
the rocks wouldn't betray  
his secrets    
though they never absorbed  
yet returned to him  
and him only  
and with a melody  
   
in the end  
the cave loved the man  
too much  
so much so  
that it absorbed his    
bones into the igneous  
   
and when    
the speleologist stumbled  
across the boulder  
he could still hear the  
echoes
