Via Instapundit, an interesting look at how Christianity changed the viewpoint toward children.
Various pagan authors describe children as being more like plants than human beings. And this had concrete consequences.
Well-to-do parents typically did not interact with their children, leaving them up to the care of slaves. Children were rudely brought up, and very strong beatings were a normal part of education. In Rome, a child's father had the right to kill him for whatever reason until he came of age.
