This snail is drawn with a sequence of numbers that helps to create its complex beauty.
This feature is one aspect that makes the snail so visually appealing and characteristically interesting: its spiral.
The spiral in that of a snail shell follows the same mathematical pattern as a nautilus,
the organization of seeds on a sunflower or the form of solar systems in their slow and stunning growth.
The pattern they share in common can be seen in Fibonacci’s Sequence,
created by Leonardo of Pisa, known as Fibonacci, or son of Bonaccio, in 1202.
The sequence itself begins with 0, 1, and proceeds by adding the two previous numbers
in the sequence to get the third. 0, 1, 1 , 2, 3, 5, 8, 13, 21, 34, 55, 89… and so on.
Geometrically, this sequence forms the perfect spiral.
