Over time all the artists have sought a way of dividing things perfect but there was nothing to indicate in what proportion should be the things (living things, objects ... ). Now we know there is a formula well known in the world of design, which can divide into equal parts, to achieve a pleasing aesthetic effect and can be very effective. This theory is called "Golden Rule", also known as "divine proportion" or "golden ratio"
The golden section is a ratio between measurements. This division harmonic of a line in extreme and mean ratio. This refers to the lower segment is the largest segment, as this is all on the line. Or cut a line into two unequal parts so that the largest segment is the entire line, as the child is to mayor.De This establishes a relationship of sizes with the same proportionality between the whole divided into major and minor, that is a similar result to the extreme and mean ratio. This ratio, or how to select a line called proportion golden ratio is adopted as a symbol of the golden section (Æ), and representation in issues of the size ratio is called the golden = 1.618.

Throughout the history of visual arts theories have emerged about the composition. Plato said, is impossible to combine two things well without a third, it takes a relationship between them that the assembly, the best bond for this relationship is everything. The sum of the parts as a whole is the most perfect relationship of proportion.
Vitruvius, a leading Roman architect, accepts the same principle but the symmetry is in agreement measures between the various elements of the work and these to the whole. He invented a mathematical formula for dividing the space within a drawing, known as the Golden Section, and was based on a given ratio between the longer sides and shorter than a rectangle. This symmetry is governed by a common module, which is the number. Otherwise defined, bisecting a box and using the diagonal of one of its halves and radio to expand the size of the square to turn it into "golden rectangle." It reaches to the ratio a: b = c: a.
According to Vitruvius, is analyzed to create a composition that, if we place the main elements of design in one of the lines that divide the golden section, the equilibrium between these elements and the rest of the design.
