While on vacation and on a day trip to Provincetown Mass, I found a shell shop and just what I was looking for-a nautilus shell for scroll reference. Here's a scan of it, very useful for proportions.

There's a great illustration of the "golden mean". We have this evidence all around us if we just look! These ratios are what makes good scroll "feel" right when we look at it (scroll done correctly that is). This is the created harmony of nature. Sometimes it is hard to capture the essence of grace & beauty and condense it into words (or, for that matter, onto a pattern cut into metal, but that is what were after): here it is...in a nautilus shell!
