Robert Ferre, of  Labyrinth Enterprises ,was commissioned by the Danville Labyrinth Project to cut a Grace Cathedral variation of the Chartres pattern into their slab. I was fortunate enough to be invited by Robert to help. 

The 43 foot sandstone slab is very impressive. They quarried it from within a formation of 15 successive layers of sandstone. You may be familiar with sandstone that's at the surface. It's hard. This freshly quarried stone from deep in the earth is soft! It's almost like a sandy clay.  It's 43 feet across. The stone mason had to be gentle with it when laying it on the bed of gravel he'd prepared. Otherwise, it could have cracked. The slab itself is about 6 inches thick . It's on the west side of the church with a view of Centre College campus.

27° Fahrenheit  The sandstone was so cold our layout tape wouldn't stay stuck to the slab.

You may notice that it is dark. The snow clouds are moving in!

The faint horizontal lines in the foreground are the path lines Robert cut on December 3rd.

The hardest part of this job was the lebendy seben times I had to take my gloves off to make a precise measurement or cut, and then put them back on!

It got dark!

It was starting to become a challenge to work. We got into the rythm of sweep and cut, sweep and cut.

You can see Robert's unique method of anchoring the 'center pivot' of the labyrinth cutting compass between us. It's a stack of three 45 pound bar bell weights on top of the pivot! 

It is darker and the snow has gotten deeper. We keep sweeping and cutting.

It was still snowing so we decided to cover up the shoveled slab with some tarps we'd been gifted by Chuck Whitehouse. It was beginning to sleet. We went home a little early this day.

I lightened up this image so you could see the detail.
