Why is there nudity in art?

The Renaissance was a period in which Humanism flourished. Humanists promoted a return to Greek and Latin classical texts as a way to enlighten their own lives, and they also emphasized the human body in art. Whereas medieval painting had been dominated by religious themes, the human body became in the Renaissance the center of artistic exploration. Concomitantly, in sixteenth-century Europe, the first dissections were performed, and poems were written about different body parts in both Italy and France. In short, the Renaissance was fascinated by the human more than by the divine.
