I've been spending quite a bit of time reading old, out of copyright, articles and books on leather and design. In one particular book, the author writes about design and proportion. Something caught my eye ... my right brained eye. I didn't equate the curves of Sheridan carving with this before until I saw the simplified drawings on page 48, figure 64.

Mathematicians amongst us probably recognize the term "The Golden Ratio." Some of you may even recall the formulas and logarithms involved. I personally would rather forget those math classes. But they say that "education" is what remains after you forget what you learned in School. So here I am staring at page 48, I see it..... The spiral created by the Golden Ratio. Suddenly much of what Mr. Paul Burnett said in his tutorials about "continuing the curve" and not "straightening out the lines" made a LOT of sense!
For those who are not cognoscente of the term the golden ratio... or it's significance in art. I invite you to explore the topic at this site. http://cuip.uchicago...lnarain/golden/
Peruse the information under activities, especially "The Golden Ratio in Art"
Basically, in quick and dirty language... The Golden Ratio is a Greek term for perfection in proportion and symmetry. (phi, (φ) ) It's also a mathematical formula. It can be applied to the face of a beautiful woman, to the items in nature and to buildings. The result of the "math" is a spiral something similar to the spiral we see in a snail shell or nautilus.
I'm sure this epiphany lit up both sides of my brain as I came to the realization of what this meant in designing and carving any design in leather. I began to think about how these 'spirals" are repeated through out Sheridan style carving.
I don't have a particular reason for sharing this other than to spark a moncum of understanding in those who like myself struggle with designing anything in Sheridan.
