The vulva is well represented in Palaeolithic art. It is mostly seen as engravings on stone, bone or ivory. The representation is obviously a well known one that has become abstracted to the point where it is often no more than an oval or circle with a single mark at its centre or at its lower edge. Although many examples are from Europe, and from the upper Palaeolithic, it occurs over a broad time range, and a very large area, including not just Europe, but Australia as well.
