I shot it for several reasons. First, the lines and color drew my eye. There's a lot of movement and I imagine it took some time to assemble the mosaic. I also thought it was curious that the symbol was on the floor of the Vatican Museum. It always seems a little odd to put sacred symbols on the floor people walk on, but I was also curious why this Jewish symbol would be on.
I am sure the designers of this floor didn't mean to hurt anybody's feelings. There are many mosaic floors with the symbol of the cross all around the world. As for this photo I hope to find out where and when exactly it was made.
