Fibonacci spiral mona lisa12/27/2023 The Mona Lisa’s body from elbow to elbow to the top of the head forms the Golden Triangle. In addition to the Golden Rectangle, Da Vinci, a mathematician as well as an artist, used the Golden Triangle to draw attention to the Mona Lisa’s face. The Golden Rectangle was believed by artists to be the most aesthetically pleasing quadrangle. Da Vinci and the Golden RectangleĪs can be seen in this picture of the Mona Lisa, Da Vinci appears to have used the Golden Rectangle to bring balance and depth into the painting. Using this formula, Leonardo Fibonacci discovered the mathematical series that can be witnessed in everything from DNA to seashells and from music to art and architecture. In the simplest of terms, The Golden Ratio is Phi squared or Phi plus 1. (Note: Phi (upper case) is 1.618… and phi (lower case) is 0.618 or Phi minus 1.) This happens only at the point where A is 1.618 times B and B is 1.618 times C alternatively C is 0.618 of B and B is 0.618 of A. Therefore, (see diagram) the ratio of a line (A) to the length of a larger section (B) is the same as the ratio of (B) to the smaller section (C). When used as the solution to a quadratic equation, Phi is the ratio of the line segments that result when a line is divided in one very special and unique way. The Golden Ratio begins with Phi, an irrational number (1.618033988749895…). In fact, it was a concept on which he studied. How did Da Vinci design his painting in just such a way as to cause onlookers to first look at the face, specifically the lips?ĭa Vinci understood, like many other artists from ancient times through the 20th century, concept of the Golden Ratio. Often, viewers ask why it is that the painting of the Mona Lisa draws them to her face and that mysterious smile.
