The Golden Ratio In 1202, after returning to Italy, Fibonacci documented what he had learned in the "Liber Abaci" ("Book of Abacus"). In the "Liber Abaci," Fibonacci described the numerical series that is now named after him. In the Fibonacci sequence of numbers, after 0 and 1, each number is the sum of the two prior numbers. Hence, the sequence is as follows: 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, 233, 377, 610 and so on, extending to infinity. Each number is approximately 1.618 times greater than the preceding number. This value:1.618 is called Phi or the "Golden Ratio". The Golden Ratio mysteriously appears frequently in the natural world, architecture, fine art, and biology. For example, the ratio has been observed in the Parthenon, in Leonardo da Vinci's painting the Mona Lisa,
