Italian and Indian roots, but found in nature naturally.
The Italian mathematician known as Fibonacci discovered a number where each number is the sum of the two preceding ones, starting from 0 and 1. The sequence is 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, etc... This symbol represents this sequence proportionally. This sequence is also known as the golden ratio and is the most aesthetically perfect proportion in harmony and balance. Many sacred sites and temples were built proportionally with these sequences. The Great Pyramids, the Partheon, Notre Dame, and the Taj Mahal are examples of architecture using this sequence.
In nature, Fibonacci's sequence is all around us. The number of petals on a flower is usually a Fibonacci number, and the spiraling growth of a sea shell progresses at the same rate as the Fibonacci sequence.
