It took a long while to stand the sculpture vertically yesterday. I was glad however to get a chance to have a good look at it in that position as I realised that I had been a little timid with the cutting out of the slots. Today I re-cut most of the slots, pushing them another half inch deeper on each of the twisting facets. I can see already that there is now a lightness that was not there before. Much better. The marble has a very subtle shifting coloration running through it hard to see here but quite evident especially when wet. No two blocks are alike I suppose, just like people.
