You just know that when the first sentence in an article is oxymoronic, it isn't going anywhere useful.
In the context of the sixteenth century that sentence made sense, they were raising the age to ten to protect young girls under ten.

In those days marriage at fourteen or even younger was nothing out of the ordinary. Anyone who made it to thirty was likely to be a grandparent.
