Fibanacci’s Spiral

The Spiral is also known as ‘The Golden Mean’ was made famous by Leonardo Fibanicci around 1200AD. It is a mathematical grid that appears in nature and art work and is a sequence of numbers 0, 1, 1, 2, 3, 5, 8, 13, 21 and 34…. The next number is calculated by adding up the two numbers before it. I.e. 1+1=2, 2+1=3, 2+3=5, 3+5=8, 8+5=13, 8+13=21, 13+21=34….

As the golden spiral gets wider it radiates away from the centre but still incorporating important scenes that visually become less important as the central focus (No. 1). It also represents the growth of a snails shell and is now used in many forms such as architecture, art and music. It is very naturalistic and appealing to the eye due to it’s shape and pleasing composition. It is argued that the ‘Rule of Thirds’ is a more simplistic version of the spiral that is used in photography.
