The male obsession with female breasts is a fairly recent phenomenon from a historical viewpoint. In all types of ancient art medium, the female breast was usually exposed. Even in the Christian realm, paintings, sculptures, and drawings commonly and frequently depicted females with one or more uncovered breasts. The Sistine Chapel is adorned with female breasts and ancient artifacts depicting nudity seem to have far greater shock value in modern times than the artists would have believed possible in their time period. The first well-known written work on human sexuality that involved reference to breasts occurred during the 2nd century BC with the advent of the Karma Sutra. In Ancient Egypt, women accented their breasts with primitive cosmetics and exotic scents. However, body painting began much earlier with primitive man and female breasts received far less focus than facial features. In truth, there are no ancient social or cultural precedents to explain the current belief that female breasts are sexual magnets for males. Female breasts and sexuality did not become strongly connected until the repressive Victorian age when women were expected to cover more of their bodies. Strangely, during this same era, the female breast reached a zenith of sorts, as women's clothing was deliberately and provocatively designed to emphasize, enlarge, and expose as much of the female breast as possible without showing the nipples. Thereafter in western societies, the female breast continued its onward march towards becoming a social icon and sexual projectile.
