I find it interesting that you think the sculptures depicting women were symbolistic of fertility and beauty found in curviness. I wonder if there is any other historical context from this time that supports this statement. I do agree with you that they were used as teaching tools. I can imagine that they were also used to tell stories, perhaps to children, to warn them and enlighten them much like the stories we tell today, ex. the boy who cried wolf, etc., are used today.
