The Venus of Willendorf
An icon of prehistoric art
dated 24,000-22,000 BCE
11.1 cm high
She has large breasts, a very round protruding middle and exaggerated genitalia. She has no face - simply circles of braided hair. There is a suggestion of arms and legs, but those are not the important aspect of the sculpture. Clearly, her makers were emphasizing her womanly aspects, but more importantly, her fertile characteristics.
The Venus of Willendorf, discovered in 1908, is believed by many to have been some sort of fertility goddess figurine. This is merely speculation, but it is an important plot element in my favorite book series: Earth's Children by Jean M. Auel. In the book, life was created by the Mother Goddess (essentially Mother Earth), and procreation was incredibly important. The Venus plays the roll of the physical idol that one can carry around in order to worship the Mother wherever you are. She has no carved face, because who can carve the true face of the Mother?
She is not, however, pregnant. She is very fat, though, which is incredibly unlikely in the time period in which she was carved. If the statue was carved from a real life model of a woman, that woman would have been very special indeed to have been able to get so fat. The fact that several figurines with similar characteristics from this time period were found across a broad geographical area ranging from France to Siberia has led to speculation about the place of women in Stone Age society - possibly a matriarchy existed where women ruled.
