The nude figure is a tradition in Western art, and has been used to express ideals of male and female beauty and other human qualities. It was a central preoccupation of Ancient Greek art, and after a semi-dormant period in the Middle Ages returned to a central position in Western art with the Renaissance. Athletes, dancers, and warriors are depicted to express human energy and life, and nudes in various poses may express basic or complex emotions such as pathos. In one sense, a nude is a work of fine art that has as its primary subject the unclothed human body, forming a subject genre of art, in the same way as landscapes and still life. Unclothed figures often also play a part in other types of art, such as history painting, including allegorical and religious art, portraiture, or the decorative arts.
