Square René-Viviani

In the midst of this square is this odd sculpture 
known as the Saint Julien fountain.  
It was constructed by Frenchman Georges Jeanclos in 1995 
and based on a tale of a curse by witches (with many characters), 
a tale told and retold since the Middle Ages.

It is an interesting square near the Seine and Notre Dame.  
I can hear the crunch of the "Paris gravel."
