Very informative article! But, I was having a hard time picturing what it looks like. Then, (once I looked it up elsewhere) I had a hard time picturing how it was used (e.g.: the portion where the rods of various lengths were lined up with 3 of the plumb lines on the instrument). I'll just keep looking up more info, though! smiley - smiley CM
