It is because of these similarities that we recognize each other as human beings and not as chickens or gazelles. But, that is where the similarity stops and people become individuals. Everyone has a slightly different arrangement of nose, eyes and mouth. Notice how some people have long thin faces, some have rather round faces. Other faces are narrow at the bottom and wider across the forehead.
Younger people have very smooth skin and older people have lines around their eyes and mouth.
Some people have small smiles and others have big,wide smiles. Finally, it is the hair that often makes a definite statement about a person. Before the camera was invented, it was the job of the artist to preserve the image of a person. Sitting for a portrait was a lengthy and expensive way to preserve a face in history. Often the portrait included not only the head and shoulders of the person but also a few objects or even a landscape that had particular meaning to the subject of the painting.
