Nothing can be loved or hated unless it is first understood.” – Leonardo da Vinci


The Mona Lisa is constructed using certain proportions which can be found in the most well-known monuments on Earth. This provides us with a reason to look at sacred geometry which is said to have originated when God created the world. We need to understand that sacred geometry is not the product of any religion but is rather the normal Euclidean and non-Euclidean geometry. Sacred geometry is the foundation upon which all other geometric shapes are based, and which can be observed everywhere in Cosmos.


In the language of mathematics, the symbol of a square means the end of a mathematical proof. As pons asinorum, also Mona Lisa can be transformed into square. It is here called Mona Lisa Square. There are shapes and forms in the Mona Lisa which find their counterparts when the painting is multiplied three times and then squared: parts of Mona Lisa’s hair and the all-seeing eye in the sky are now in congruence. Similarly, the small, blue horizontal lines in the background of the Mona Lisa have thus far puzzled students of Mona Lisa.


To understand the following equations requires familiarity with terms such as triangle, square, circle, radius, perimeter etc. The reader should also be able to calculate the surface area, to understand the Pythagorean Theorem and all the basic operations concerning Rational numbers. We will first discuss a few mathematical definitions, which are used in the study. Finally, the theorems and proofs are built into a general point of view, which is called the Image of the All, or the Image of God.


Three Mona Lisas putted into square, and thus horizontal lines are matching.

Definition 1. (Number π)

π is commonly defined as the ratio of a circle's circumference C to its diameter d: (Arndt & Haenel, 2001)

π = C / d.

The ratio C/d is constant, regardless of the circle's size.


Definition 2. (Golden ratio φ)

In mathematics, two quantities are in the golden ratio if their ratio is the same as the ratio of their sum to the larger of the two quantities. The golden ratio is expressed with symbol φ. (Livio,, 2015)


Notice: An alternative definition to the golden ratio is already formed in Theorem A, which stated that any non-negative integer divisible by 3 can be divided into the legs of right triangle with ratio 1 : 2, and when comparing the sum of shorter leg and hypotenuse against the longer leg, the result is always the golden ratio.


Definition 3. (Mona Lisa Square)

A square with a side length of 792 is called the Mona Lisa square, because its dimensions match the height of the painting (in mm).


Notice: In sacred geometry (also in Euclidean) the forming of a square is only possible with four circles. As said, the four circles symbol is found on the bodice of Mona Lisa’s dress (Image 19. Right). In the following calculations we choose to use the height of Mona Lisa – 792 mm. It is eleven times the mysterious number 72.


Definition 4. (Earth Circle and Earth Square)

Image of Mona Lisa square and the Earth.

Image 34. Mona Lisa matches Earth’s dimensions


A circle with a diameter of 792 is called the Earth Circle, since its dimensions match those of Earth, whose diameter is 7920 miles (and 792 in tens of miles). When a Square is formed around the Earth Circle, one side of such a Square is 792, and thus it is called the Earth Square.


Notice: The Earth Circle fits exactly inside the Mona Lisa Square because of their matching dimensions. The Mona Lisa Square can thus also be called the Earth Square.


Definition 5. (Moon Circle and Moon Square)

A circle with a diameter of 216 is called the Moon Circle, since its dimensions matches with those of the Moon, whose diameter is 2160 in miles (and 216 in tens of miles). When a square is formed over the Moon Circle its side length is 216, and it is called the Moon Square.


Image shows the Earth and the Moon in miles and divided by 720.

Image 35. Left: Earth and Moon in miles. Right: Dimensions simplified (divided by 720).


Notice: The Earth Square and Circle are in proportion to the Moon Square and Circle, when the Moon is placed above the Earth. Now is also possible to modify the dimensions so that they are easier to treat in calculations.


Definition 6. (Earth-Moon Radius)

Radius of the Earth and the Moon is visible.

Image 36. The Earth-Moon Radius


When the Moon is placed above Earth, it is possible to draw a circle connecting them, with a radius of the Earth’s and Moon’s radius together. We call it the Earth-Moon radius. Correspondingly a Circle, which radius is the Earth-Moon Radius, is called Earth-Moon Circle.


Notice: With simplified numbers the Earth-Moon radius is 7 and correspondingly the diameter of Earth-Moon Circle is 14 (= 2 x 7).
