"Wow! What a great pic!" I said to myself, when I looked at the two sisters crucified on the same cross. Then I noticed I had 'liked it' over two years ago. It is indeed a very powerful image: full of agony, shame, pity and sibling rivalry! Like roxie said: "Who's at fault?" I'll put my money on the younger sister. She probably did something reckless and stupid. A mess that big sis tried to help her get out of but wound up condemned herself.
Now they have lots of 'together time' to work out their issues.
Time to repost the luckless sisters, along with Michele Patri's death-in-the-arena emulation.
