[The golden number. Applications to architectural and structural cranio-facial analysis]

The Golden Number, expressing in numbers what ancient Greeks called the "Divine Proportion", has a value of 1.618. This number is found in numerous natural phenomena, geometrical propositions and human architectural constructions. These proportions are worth being compared to those of the human face. The author shows that this "golden proportion" is found in many cephalometric measurements and in the comparison of the various stages of facial growth.
