Many artists and scientists have tried to understand or quantify the form of the perfect, ideal, or most beautiful face both in art and invivo. A mathematical relationship has been consistently and repeatedly reported to be present in beautiful things. This particular relationship is the golden ratio. It is a mathematical ratio of 1:1.618 that seems to appear recurrently in beautiful things in nature as well as in other things that are seen as beautiful. Dr. Marquardt developed a facial golden mask that contains and includes all of the one-dimensional and two-dimensional geometric golden elements formed from the golden ratio and he claimed that beauty is universal, beautiful faces conforms to the facial golden mask.
The frontal view of the face is the most important view because we generally perceive (or view) each other (particularly when we interact socially) from the front not from the side. Our evaluation of how human another face appears occurs from the frontal view. Therefore this view is most critical for our evaluation of another individuals humanness (Or Attractiveness).
In the frontal view, the vertical relationships between the facial components as well as the horizontal relationships between the facial components can both be assessed.
