I know many interpret this as the Godness Pensive Athena mourning those who fell in 460BC, other say she is standing at a boundary stone for Athenas' sanctuary. The most realistic version is that she is trying to pry that marble stone out of the ground to take it home and make a marble sink out of it for her bathroom.
I'll let you decide. There may also be another message here.
Thank you Katerina, a lovely thought. I did see that Cheryl H. started a Paris Peace project here at UOIMA.
