Golden ratioThe golden ratio is a special number approximately equal to1.618. If you divide a line into two parts so that: the longer
part divided by the smaller part is also equal to the wholelength divided by the longer part, then you will have thegolden ratio. The golden section is also a term that describesa unique measurement phenomenon in nature wherein theoff-centered proportional finite value of about 5 to 8represents a measurement with infinite values.

Many artists, architects and mathematicians believed (andstill believe) this proportion is aesthetically pleasing.
Mathematicians have studied the golden ratio because ofits unique and interesting properties.

The Middle Ages art mainly consists of Romanesque and Gothic art.Romanesque art developed between about 1000 and 1300 inconjunction with the rise of monasticism in Western Europe.The style developed initially in France, but spread to Christian
Spain, England, Flanders, Germany, Italy, and elsewhere to becomethe first medieval style found all over Europe.
Gothic art was a Gothic art developed in France out of in the mid-12th century and spread to all of Western Europe, but took over art
more completely north of the Alps, never quite effacing more
classical styles in Italy. In many areas, especially Germany, LateGothic art continued well into the 16th century, before being
subsumed into Renaissance art.

The Renaissance marks the period of European history atthe close of the Middle Ages and the rise of the Modern
world. It represents a cultural rebirth from the 14th through
the middle of the 17th centuries. Early Renaissance, mostlyin Italy, bridges the art period during the fifteenth century,between the Middle Ages and the High Renaissance in Italy.It is generally known that Renaissance matured in Northern
Europe later, in 16th century.

After this period the Golden Section was not more used inart until present times when painters and architects beganagain to project their works according to this proportion.

The CN Tower in Toronto, thetallest tower and freestandingstructure in the world, containsthe golden ratio in its design. Theratio of observation deck at 342meters to the total height of553.33 is 0.618, the reciprocal ofPhi!

Piero della Francesca
It portrays Christ being baptisedby John, his head surmounted by
a dove representing the HolySpirit. Christ, John's hand, thebird and the bowl form an axis
which divides the painting in twosymmetrical parts. A second
division is created by the tree onthe left, which instead divides itaccording to the golden ratio.

Sandro BotticelliThe Birth of the Venus
Botticelli (1445-1510) had to befascinated by the golden
proportion, since he used it forhis "Birth of Venus. " In fact ifyou measure the height of the
navel height overall, theirrelationship will be 0.618, as
well as between the distancebetween the neck of the femurand the knee and the length of
the entire leg or therelationship between the
elbow and the tip of the middlefinger and arm length.

LeonardoDa Vinci
He explored the human body involving in the ratiosof the lengths of various body parts. He called this
ratio the "divine proportion" and featured it inmany of his paintings and used this ratio very
impressive.

Using the left side of the painting as a side, create a square on the left of thepainting by inserting a vertical line. Notice that you have created a square and a
rectangle. The rectangle turns out to be a Golden Rectangle, of course. Also,draw in a horizontal line that is 61.8% of the way down the painting (.618 - theinverse of the Golden Ratio). Draw another line that is 61.8% of the way up the
painting. Try again with vertical lines that are 61.8% of the way across both fromleft to right and from right to left. You should now have four lines drawn acrossthe painting. Notice that these lines intersect important parts of the painting,
such as the angel, the woman, etc. Coincidence? I think not!

Measure the length and the widthof the painting itself. The ratio is,
of course, Golden. Draw a
rectangle around Mona's face(from the top of the forehead tothe base of the chin, and from leftcheek to right cheek) and notice
that this, too, is a Golden
rectangle.

At this time in Northern
Europe Albrecht Durer workedon similar problems. According
to one of his letters he met LucaPacioli in Italy.
Albrecht Durer developeddetailed theory about proportions of
the human body. Important placein his work was taken by
the hold golden ratio. He found thatthe growth of man is
divided of golden ratio fromwaist line.

The horizon falls exactly at the

Golden sections appear in the stairsand the ring of the trumpet carried
by the fourth woman from thetop. The lengths of the gowns from
the sash below the breast to thebottom hem hits the phi point at
their knees. The width of the interiordoor at the back of the top of the

In addition, the windows in the background are formed by a largedodecahedron. Dodecahedrons consist of 12 pentagons, which
exhibit phi relationships in their proportions.
The Sacrament of the Last Supper
Following Da Vinci'slead, Dali positionedthe table exactly atthe golden sectionof the height of his
painting. He
positioned the twodisciples at Christ'sside at the golden
sections of thewidth of the
composition.
