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.
Nude female figures called Venus figurines are found in very early prehistoric art, and in historical times, similar images represent fertility deities. Representations of gods and goddesses in Babylonian and Ancient Egyptian art are the precursors of the works of Western antiquity. Other significant non-Western traditions of depicting nudes come from India, and Japan, but the nude does not form an important aspect of Chinese art. Temple sculptures and cave paintings, some very explicit, are part of the Hindu tradition of the value of sexuality, and as in many warm climates partial or complete nudity was common in everyday life. Japan had a tradition of mixed communal bathing that existed until recently, and was often portrayed in woodcut prints.
The earliest Greek sculpture, from the early Bronze Age Cycladic civilization consists mainly of stylized male figures who are presumably nude. This is certainly the case for the kouros, a large standing figure of a male nude that was the mainstay of Archaic Greek sculpture. The first realistic sculptures of nude males, the kouroi depict nude youths who stand rigidly posed with one foot forward. By the 5th century BCE, Greek sculptors' mastery of anatomy resulted in greater naturalness and more varied poses. An important innovation was contrapposto—the asymmetrical posture of a figure standing with one leg bearing the body's weight and the other relaxed. An early example of this is Polykleitos' sculpture Doryphoros (ca. 440 BCE).
