|  |  | Concept Of Beauty In 1498, while working on The Last Supper in Milan, Leonardo da Vinci collaborated with the mathematician Fra Luca Pacioli on the book called "Of Divine Proportion".
       A central concern of the book was the Fibonacci mathematical sequence, 
        a series of numbers in which each new entry is the sum of the previous 
        two (0,1,1,2,3,5,8,13,21,34,55...). A mysterious ratio of 1:1618 hovers 
        between any two numbers in the series, reproducing the harmonious proportion 
        known as "The Golden Mean". Thought to be a reflection of God's divine 
        intention for an ordered cosmos, it was called "The Divine Proportion", 
        and was given the name Phi. This proportion (roughly 3 to 5) has intrigued mathematicians and philosophers 
      for centuries and was utilized by artists and architects in ancient Greece 
      and Egypt. It can be observed in plant and flower design, proportions in 
      the human body, and almost everything considered beautiful in the natural 
      world and it is seen in the incremental spiral of the Nautilus shell. I believe the Fibonacci spiral design demonstrates nature's way of building 
        quantity without sacrificing quality. It has been deemed the most perfectly 
        harmonious relation between a whole and its parts and is universally 
        pleasing to human sensibilities. A well-proportioned human face adheres 
        to this ratio. The dancing Shiva of Hindu mythology holds a Nautilus shell 
        in one hand as an instrument through which he initiates creation. |
